ledctl: /dev/nvme0n1: device not supported

I want to use ledctl to locate my nvme whose model is INTEL SSDPE2KE020T7. But ledctl reported device not supported. Why does this happen?

ledmon with zfs

hello
i have proxmox installation 4 disk connected on the Motherboard with sata.
i know the sata port but should find out the sda port

in my case i see the sda, sdb sdc sdd but the led will not flash maybe because the Disk are in a IcyDock - FatCage MB153SP-B?

ledctl -L

/sys/devices/pci0000:00/0000:00:17.0 (AHCI)

i only have one maybe should be 4 entry for each disk,

have a nice day

Define Ledmon behavior for corner cases

Problem description

For some corner case scenarios Ledmon behavior is not obvious and cannot be easily
determined. The goal is to decide how ledmon should behave in those scenarios.
This list contains known undefined behaviors for the moment of submitting. I strongly
believe that it is a good point to start. Our expectation is to define rules
which ledmon should follow. Those rules will be noted and saved in the
documentation. This new file will be added to repository. Required changes will
be applied to product later.

Scenario 1: Manual stop / RAID deactivation

Problem:

When RAID is stopped, Ledmon marks all disks as normal. It does not check the reason.
It may be caused by:

user, if raid stop is requested
system, if it is caused by drive failure or IO errors.

From Ledmon perspective there - there is no good way to tell the difference.

Question:

If RAID array disappears, should member LEDs stay normal or blink failure?

Steps to reproduce:

Manual stop:
Create container with 2 disks:
#mdadm -CR $CONTAINER_NAME -e imsm -n2 $DISK1 $DISK2
Create RAID:
#mdadm -CR $RAID_NAME -l1 -n2 /dev/$DISK1 /dev/$DISK2
Stop created RAID:
#mdadm -S /dev/md/$RAID_NAME

System stop:
Create container with 2 disks:
#mdadm -CR $CONTAINER_NAME -e imsm -n2 $DISK1 $DISK2
Create RAID:
#mdadm -CR $RAID_NAME -l0 -n2 /dev/$DISK1 /dev/$DISK2
Stop RAID by system – remove one drive:
#echo 1 > /sys/block/$DISK1/device/delete

Actual result

RAID is removed from system (see /proc/mdstat). If one drive is removed then it is
marked as failed by Ledmon. Other drives are marked as normal.

Scenario 2: Matrix RAID – remove one volume.

Problem

Up to two volumes can be created upon one IMSM container. Each array can have different
failure tolerance. As a result one volume can be gone, but second one is still
active. It is a more complicated case for Scenario 1.

Question

Should Ledmon mark failure on each array member or only on failed members?

Steps to reproduce:

Create container with 2 disks:
#mdadm -CR $CONTAINER_NAME -e imsm -n2 $DISK1 $DISK2
Create partial capacity RAID1:
#mdadm -CR $RAID_NAME_1 -l1 -n2 /dev/$DISK1 /dev/$DISK2 -z 10G
Create RAID0 from rest of free space :
#mdadm -CR $RAID_NAME_2 -l0 -n2 /dev/$DISK1 /dev/$DISK2
Remove one drive or stop one volume:

#echo 1 > /sys/block/$DISK1/device/delete

#mdadm -S /dev/md/$RAID_NAME_2

Actual result

If DISK_1 is removed then it is marked as failed. RAID0 disappears, RAID1 is
degraded. DISK_2 is marked as normal.

Scenario 3: Remove mounted volume

Problem

If volume is in use then mdadm is not able to unmount it before stop. If
array fails, then - as a last resort - udisk is triggered. The root cause is the same as for Scenario 1 and Scenario 2 - array becomes failed but in this case
RAID won't be stopped. Ledmon can't detect that array is failed, it relies on
md device existing.

Question

How Ledmon should behave when it is not possible to stop RAID when it becomes failed?

Steps to reproduce:

Create container with 2 disks:
#mdadm -CR $CONTAINER_NAME -e imsm -n2 $DISK1 $DISK2
Create RAID:
#mdadm -CR $RAID_NAME -l0 -n2 /dev/$DISK1 /dev/$DISK2
Mount RAID
#mkfs /dev/md/$RAID_NAME
#mount /dev/md/$RAID_NAME /mnt
Generate IO:
#dd if=/dev/urandom of=/dev/md/$RAID_NAME &
During IO remove one drive:
#echo 1 > /sys/block//device/delete

Actual result

Ledmon marks removed drive as failure. Second drive from this RAID is marked as normal.

Summary

Those three scenarios have one common result, in each case RAID
becomes unusable because it is failed or disappears from system. We should define
and document the behavior which should be expected in this case.
Marking as failure looks reasonable, but it can be misleading in some cases. From
other hand marking as normal won't inform about any raid failure. We want to know
user expectation and provide best solution.

ledctl dont change LED status

Hi,

i have a Supermicro Mainboard H11DSi-NT with Supermicro Backplane BPN-SAS3-743A-N4
I hoped the new amd-sgpio patch would work an I could change die LEDs of the
Backplane, but nothing changed. Not sure if my SATA-Controller of the MB is supported.
The activity LED is blinking blue, if the softraid writes to disk and at PC start i can see
a red LED flashing very short. So I think the cable ist right.

ledctl not working with simple Intel SATA controller

Hi there,

I'm running a Debian Testing system on a Biostar HM110MHV3 mainboard and having issues controling the LEDs of my SATA devices, connected to an ICYBOX IB-55SSK (https://icybox.de/en/product.php?id=336 --> as far as I know, just wires SATA from mainboard to the connected disks, nothing special inbetween but a nice case and a fan), which has a combined power/activity LED for each disk.

Used ledmon is version 0.95-1

Two disks are an mdadm raid1, so I not only have /dev/sdX, but also a /dev/md127
other disks run in single mode

ledctl -L says:

# ledctl -L
/sys/devices/pci0000:00/0000:00:17.0 (AHCI)

If I set loglevel to all, I get f.i. this:

# ledctl locate=/dev/sdb
ledctl: Unable to issue IPMI command GetSystemInfo
ledctl: (raid_device_init) path: md127, level=2, state=6, degraded=0, disks=2, type=1
ledctl: (_set_block_state): device: sdc, state: NORMAL
ledctl: (_set_block_state): device: sdb, state: NORMAL

LED does nothing... tried different pattern. Same ... --> nothing.

I'm not very deep into the underlying technical stuff required for this. Maybe this helps to identify the problem?

# lspci | grep -i AHCI
00:17.0 SATA controller: Intel Corporation Q170/Q150/B150/H170/H110/Z170/CM236 Chipset SATA Controller [AHCI Mode] (rev 31)

What am I doing wrong? Or is my system simply not compatible? Any way of letting drive-led blink to show hw-issues or to identify drive?

br,
Alex

ledctl overrides ibpi request under certain conditions

Not using ledmon, just using ledctl to manage LED status of one of the soft raid devices.

ledctl is expected to update status of LED with user requested irrespective of current RAID conditions.

When raid constructions is "In progress" and requested to set to Normal, ibpi requested status gets overridden by value regarding to "DEGRADED".

Clarify supported hardware configurations of LEDs

Manual is not very clear about which cases are supported.

I have recently bought OImaster MR-6601 (Thermaltake MAX 2506) sata bay, and I was exploring if it is possible to activate locate blinking on it. Activating locate pattern with ledctl locate=/dev/sda did nothing.

The sata bay looks looks like this:

There are two LEDs for each bay: power (blue) and access (red). I thought that Access led and Status led are synonyms. But looks like it is not, according to what I have read in #58.

The man page for ledctl says:
There are two types of systems: 2-LEDs systems (Activity LED , Status LED ) and 3-LEDs systems (Activity LED , Locate LED , Fail LED ).
So can you clarify about led namings on bays like mine?
Activity led - am I right that it is led which blinks when you write/read data from the drive?
Status led - am I right that it is Power led? Or what is status?
Access led - am I right it is the same as Activity led?

So my bay is 2-led? If not, then why there is no mentioning in man about such bays with one led (Access Led, power LED is not counted it seems). May it be added to man page?

And another statement which is not very clear to understand to me:
LED management ( AHCI ) and SAF-TE protocols are not supported.
Why it says led management not supported? I have In ledctl -L this output /sys/devices/pci0000:00/0000:00:17.0 (AHCI). So is my controller supported?

Gauging interest in a C library API

Has there been any interest in a C library API which provides the ability to list/get/set etc. individual LEDs? Would folks be amenable to integrating a change which adds this if one was supplied?

Ledmon changes device name assigned after every loop.

If there are multiple namespaces defined, I can see that ledmon is changing namespace assigned in every loop:

ll /sys/block/| grep nvme7
lrwxrwxrwx 1 root root 0 Mar 21 19:35 nvme7n1 -> ../devices/pci0000:5d/0000:5d:05.5/pci10001:00/10001:00:03.0/10001:02:00.0/nvme/nvme7/nvme7n1

It could affect scenarios with multiple namespaces defined and VROC RAID array on top of first one, however I didn't dig into it. Need to be investigated.

ledctl outputs nothing when run in user mode

When ledctl is run without sudo or with a user that is not root, then it sends no appropriate message.

Messy tagging

Is it any particular reaso why sometimes new version is tagged with leading v and somerimes not? 🤔
That breaks my automation 😋

compilation errors because of references to packed struct members

With gcc 9.2.1, I'm getting a lot of these during the compilation of ledmon-0.93:

...

...

To be honest, I don't know if such references are even supposed to work, but I can imagine that the generated code might act funny on architectures like ppc64.

difference between software ledmon and sgpio

There is a software named sgpio in fedora and rhel, I noticed that it is also a tool about controlling LEDs in an enclosure via sgpio.
And sgpio's author is also an employee of intel , but since 2008, it has not been updated.

So is ledmon an alternatives of old sgpio?

ledctl segfaults

This currently happens with ledmon-0.92.

Here's an excerpt from a gdb session:

The problem is that ibpi_str[state->ibpi] assumes that state->ibpi maps into ibpi_str, but that's not correct. I'm not sure what the intention of the mapping is, therefore I'm not sure how to fix this properly.

Locate empty slot example

Can you please provide an example locate command for an empty slot? There is no associated drive letter and am unsure what pattern to pass.

locate
Turns Locate LED associated with the given device(s) or empty slot(s) on.

Patch for new Dell servers 13g/14g

The current version of ledctl/ledmon does not support NVME SSD correctly on latest generation of Dell servers.

0001-Add-support-for-Dell-12g-13g-14g-servers-for-drive-b.patch.txt

The return value of 'sscanf()' should be checked

ledmon/src/config_file.c

Line 146 in 0b4e9df

sscanf(s, "%d", &conf.scan_interval);

ledctl slot commands "--controller" option is misleading

Based on ledctl --help it is not clear how to use the slot commands ("--list-slots", "--get-slot", "--set-slot") correctly:

--list-controllers                                                    -L                                      Displays list of controllers detected by ledmon.
--list-slots --controller CONTROLLER                                  -P -c CONTROLLER                        List slots under the controller, their led states, slot numbers and devnodes connected.
--get-slot --controller CONTROLLER --device DEVNODE / --slot SLOT     -G -c CONTROLLER -d DEVNODE / -p SLOT   Prints slot information, its led state, slot number and devnode.
--set-slot --controller CONTROLLER --slot SLOT --state STATE          -S -c CONTROLLER -p SLOT -s STATE       Sets given state for chosen slot under the controller.

It is not clear that the "--controller" parameter actually requires the controller type, e.g. "VMD", not the actual controller path printed by --list-controllers. The ledctl manpage does mention this for the "--list-slots" command, but not for "--get-slot" and "--set-slot".

ledmon not working on centos 5

Hello,

I noted on http://rpm.pbone.net/index.php3/stat/4/idpl/23726038/dir/centos_5/com/ledmon-0.77-3.1.x86_64.rpm.html that that version of ledmon is supposed to work on centos 5 even though the rpm seemingly no longer exists. I therefore downloaded the source tar from https://sourceforge.net/projects/ledmon/files/ledmon-0.77/. I was able to get it working after installing "sg3_utils-libs-1.25-5.el5". I also had to create /usr/include/linux/bsg.h from a copy available online and do "cp /usr/lib64/libsgutils.so.1 /usr/lib64/libsgutils2-1.45.so.2" to get the binary to run.

However, although ledctl executes, it will not locate any drives. Perhaps this is the cause from strace:

lstat("/sys/dev", 0x7fffa8e3b6c0) = -1 ENOENT (No such file or directory)

Since that leads to it erroring out:

lstat("/sys/dev", 0x7fffa8e3b6c0) = -1 ENOENT (No such file or directory)
write(3, "0x5cd40fe6:0x0005e6f1 WARNING: I"..., 88) = 88

stat("/etc/localtime", {st_mode=S_IFREG|0644, st_size=3519, ...}) = 0
writev(2, [{"ledctl: IBPI LOCATE: missing blo"..., 64}, {"\n", 1}], 2ledctl: IBPI LOCATE: missing block device(s)... pattern ignored.
) = 65
sendto(4, "<12>May 9 07:32:54 ledctl: IBPI"..., 84, MSG_NOSIGNAL, NULL, 0) = 84
close(3) = 0
munmap(0x2b994747e000, 4096) = 0
close(4) = 0
exit_group(0) = ?

ls /sys/dev

ls: /sys/dev: No such file or directory

The kernel is: 2.6.18-398.el5.028stab116.1

Is this a known bug? Or is there an older version that does not rely on /sys/dev's presence?

Thanks!

compile error of format not a string literal and no format arguments

Hi,
I came across an compile error in util.c since commit
dfa5e66 ("[ledmon] Unify logging methods.")

error is:

utils.c: In function '_log':
utils.c:314:21: error: format not a string literal and no format arguments [-Werror=format-security]
fprintf(s_log, lli->prefix);

I try to add an "%s" to it, then the error is not produced:
fprintf(s_log, "%s", lli->prefix);

Is it an issue? Could you help check?

Thanks,
Liwei.

ledctl

I don't know how the ledctl -x option is supposed to work.
If I did "ledctl -x /dev/sda" , the sda led is first on
and then "ledctl -x /dev/sdb", the sdb led is on but sda led is off. Isn't "-x" option touches one led only? The 2nd command should not bother /dev/sda at all?

Or I am supposed to use -x with locate command together?
Thanks!

Weird behavior when both VMD and NPEM are inplace

Nvme9n1 is not connected to npem controller but it is determined as npem capable.
Ledctl couldn't find device when asked for VMD.

No Enclosure Script

Here's a simple script I made to create activity to identify a failed HDD in a zfs pool where the disks are directly connected to the motherboard thus no enclosure and ledctl won't work.
Requires zpool, awk, & ioping

sudo zpool status TANK | awk '$2 ~ /^FAULTED$/ {system("sudo ioping /dev/disk/by-id/" $1)}'

where TANK is the zpool tank name

ledmon stopped working after upgrade from debian 10 (buster) to debian 11 (bullseye)

Hi,

I have an issue with ledmon after upgrading my debian installation from debian 10 to debian 11.

Debian 10 uses ledmon version 0.90-0.1
Debian 11 uses ledmon version 0.95-1

My system has a Supermicro X9DRD-7LN4F motherboard and a BPN-SAS2-846EL1 24 slots backplane with an LSI expander.

On version 0.90-0.1 ledctl works fine and i can identify my disks without issue.
However after upgrading to debian 11 (and ledmon to 0.95-1) it always throws the following error:

ledctl: /dev/sdX: device not supported
ledctl: IBPI LOCATE: missing block deivce(s)... pattern ignored.

When i then manually downgrade the ledmon package on debian 11 to version 0.90-0.1 it starts working again so it doesn't seem to be a kernel/driver issue but an issue in the ledmon package itself.

If i need to provide more information or do any testing, please let me know.

Kind regards,
Caspar

How does one provide patches to this project?

In order to submit fixes/enhancements/etc? Also, is there an official maintainer?

Turning off the locate LED after ejecting the device

I use ledctl to identify which disk to pull when a disk fails: ledctl locate=/dev/sdn

This works well. But, once I eject the faulted device, ledctl locate_off=dev/sdn no longer works (since, I suppose, the /dev node is no longer there).

Is there a solution or workaround for this?

Controllers that have enclosure devices without expanders are not supported

On our hardware, the controllers use SES thus an enclosure device. ledctl does not find expanders in the sysfs path and tries to use SMP which is not supported by our device.

Build for macos/bsd

Is there a build available for macos/bsd unix to use these tools?
Is it thinkable to port?

Not enumerated block device(s) - supporting NVMe

NVMe usage are seen primarily two ways as it stands. One is via kernel and another with SPDK.
When SPDK is used with, currently ledmon/ledctl cannot be used.

Primary reason is - SPDK would load stub driver instead of "nvme" driver and all traces of the device shall disappear from the sysfs path that qualifies it as valid "block" device.

Now - ability to "manage" LED is a slot feature than NVMe itself and slot does not disappear when running SPDK (or in kernel). If tool has ability to absorb PCIe path of the NVMe drive - now same tool can also be used with SPDK as well. Note that "/dev/nvme*" are used merely to find PCIe device path. Also, NPEM support that got added to this tool makes it even more powerful and compelling to be used in multiple application.

RFE: Ability to query current state of LEDs

Is there any interest in adding the ability to query the state of the LED's? At the moment it appears that only turning on/off is provided.

parallel build may failed sometimes

Hi Expert,
when build ledmon parallel will failed with error:
"git/src/_build/cntrl.o: file not recognized: file truncated"
or
"git/src/_build/utils.o: file not recognized: file truncated" or failed with other .o file.

the error rate may 1/10 or 1/8, build with 40 job parallel(make -j 40)

Could you help check if it is a real issue.

Thanks,
Liwei.

ledctl overrides status of other LEDs

with every launch of the ledctl application, it loops and resets all of the other LEDs.

Fix --help for ledctl

The column size should be limited to 100 chars (compatibility with terminals and kernel style).

Help should be divided into

general_help;
print modes and IBPI (backward compatibility)
help per mode
print mode specific parameters if --help is used after mode

SES is not used for enclosure devices that are directly connected.

We have a controller that has enclosure devices connected without expanders, they have to be controlled with SES and they cannot be controlled with smp.

The issue is in these lines:

ledmon/src/block.c

Lines 89 to 91 in 8cb8c5f

 } else if (cntrl->cntrl_type == CNTRL_TYPE_SCSI 

 && dev_directly_attached(path)) { 

 result = scsi_smp_fill_buffer;

and this function:

ledmon/src/block.c

Lines 55 to 60 in 8cb8c5f

 int dev_directly_attached(const char *path) 

 { 

 if (strstr(path, "/expander") == 0) 

 return 1; 

 return 0; 

 }

If it finds no "/expander" in the path, it decides to use the function: scsi_smp_fill_buffer for this device. I think you should check if its an enclosure device differently not based solely on that string.
