pblk: corrupted read LBA about femu HOT 2 CLOSED

Hi,

When I run FEMU as a write box, instantiate pblk, and mkfs. Dmesg warns me "corrupted read LBA".

This happens each time when pblk tries to read some data from the device.
It seems that the rqd didn't return the LBA metadata correctly.
Same configuration under qemu-nvme may not print same warnings.

Thanks for reporting this.

We're aware of this bug. We're looking into this. However, this doesn't affect you to use LightNVM. It's just a warning that there is a metadata mismatch between LightNVMs' version and FEMU's. You can still use file systems on top of pblk targets and the data are still correct.

For now, we suggest to comment out the WARN() statement in function pblk_read_check()
