PEs Shows ??? in LVM

Hi All,

I have logical volume /dev/vg00/lvol8 which shows ??? in LVM column of pvdisplay. I think it should show /dev/vg00/lvol8. I think because of this I am unable to do fsck. How can I resolve this problem.

Please let me know how to correct this problem.

Thanks in advance

Can you post your "pvdisplay -v /device" as a text file?

Also, what does vgdisplay -v vg00 produce?

Hi Venkat,

I would move aside "/etc/lvmtab" and execute "vgscan -v", which should re-create the file - but with proper contents. Then check with "vgdisplay", "lvdisplay", and "pvdisplay", again.

Additionally check wether you have the device-files "/dev/vg00/lvol8" (a block device) and "/dev/vg00/rlvol8" ( a character device).

If they are missing you could re-create them with:
mknod /dev/vg00/lvol8 b 64 0x000008
mknod /dev/vg00/rlvol8 c 64 0x000008

HTH,

Hi Venki:

Have a look at Technical Knowledge Base document #KBRC00005706. This describes the procedure to determine the missing device files and recreate them,
