Good day.
I have a question, maybe someone can help me with it.
The problem is I have a target node with 3 disks in on handler sda, sdb,sdc.
For some reason, drive /dev/sdc failed, and was manually removed from
initiator node. I checked target node, removed LUN and device from
handler manually.
Then, when I try to add device, I see an error:
root@sas00: echo "add_device sas00_sdc filename=/dev/sdc; nv_cache=1"
> /sys/kernel/scst_tgt/handlers/vdisk_fileio/mgmt
-bash: echo: write error: No such device or address
root@sas00: ls -la /dev/sdc
brw-rw---T 1 root disk 8, 32 Mar 18 05:31 /dev/sdc
Here is dmesg message:
[10161276.316398] dev_vdisk: Registering virtual vdisk_fileio device
sas00_sdc (NV_CACHE, ROTATIONAL)
[10161276.316563] dev_vdisk: ***ERROR***: filp_open(/dev/sdc) returned error -6
[10161276.316620] scst: ***ERROR***: New device handler's vdisk_fileio
attach() failed: -6
I assumed, that the disk could be used by another process, but lsof
shows nothing for sdc:
root@sas00:/sys/kernel/scst_tgt# lsof | grep sdc
root@sas00:/sys/kernel/scst_tgt# lsof | grep sdb | head
sas00_sdb 1816 root cwd DIR 0,18
260 2 /
sas00_sdb 1816 root rtd DIR 0,18
260 2 /
sas00_sdb 1816 root txt unknown
/proc/1816/exe
Why can't it be attached now? Any ideas?
Thanks
