otheus / pdsh Goto Github PK

Hi!
Since we're still using Torque as resource manager on the compute clusters at 
our site, I created a torque-module (similar to the slurm-module; in fact, I 
modified the slurm-module to instead talk to torque/pbs-server).
Is it something that you would be interested in including in pdsh?
The module is not thoroughly tested yet, but afaik it works at my place. 
Autotools and spec-stuff also seems to work (on CentOS5).

Currently pdsh loads all modules found in pkglibdir,
but unloads modules that fail to initialize, typically
due to conflicting module options. Therefore, present
but conflicting modules do not appear in the output of
-L and -V.

At least one user has noted that it will be less confusing to
list conflicting modules in -L and -V, but somehow denote the
inactive modules.

I stumbled across the following issue

echo -e 'n01:\nn2:' | dshbak -c

It get collected as 
n[01-2]
which then would get expanded to
n01,n02
by pdsh.

I'm really not much of a perl hacker, so I don't present any patch for it 
though. ;)

        Hello Mark,                                                             
please find attached the perl script my colleague has kindly                    
turned dshbak(1) into on my request.  Maybe dshbak might be                     
modified to include this functionality but we needed at least                   
something capable of putting each node's output separately                      
and it might be useful for others as well.                                      

Alexander is CCed, and I've finally wrote a manpage along with                  
including the script into ALT Linux package:                                    
http://packages.altlinux.org/pdsh

Usage: dshdir -d DIR [-f]

Add support in pdsh to execute a different command per target,
i.e. read from a file.

See Debian bug here:

http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=594884

From an sf.net user:

"It would be nice, if pdsh could be used in a pipe. For example:

 $ echo foo bar | pdsh -w host1,host2 md5sum"

In order to support anything like this, pdsh first needs to support
broadcasting of stdin. This is on the TODO list, but is low priority
at the moment.

Since the arguments in PDSH_SSH_ARGS_APPEND are appended after
the default args of:

 "-2 -a -x -l%u %h"

the new args come after the hostname and mess up the ssh command,
thus rendering this env var useless. The arguments need to be appended
after the last real ssh option, not the hostname, which is compulsory
and probably should not be optional anyway.

It would be handy to be able to provide a default value for the -e option to 
pdcp/rdcp from an environment variable. Patch attached relative to trunk r1260.

I am trying to use pdsh to startup a hiphop server in daemon mode. I see that 
pdsh hangs on the issuing machine.

If I shutdown hiphop on the target machine, through other means, pdsh shuts 
down on the issuing machine.

As a workaround I am using the '-u' option to timeout after 10 seconds. But 
this is error-prone.

If you can give me reasons why this is happening (created process not shutting 
down file descriptors etc) I can fix this on hiphop.

I would really appreciate any pointers.
