Re: [linux-lvm] pvscan/vgscan/lvscan error



Hello,
I've found more errors using lvm commands. This time using vgdisplay and
lvdisplay:

# vgdisplay
  /dev/sdb: read failed after 0 of 4096 at 0: Input/output error
  /dev/sde: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdf: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdg: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdi: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdk: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdl: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdp: read failed after 0 of 4096 at 0: Input/output error
  --- Volume group ---
(...)

# lvdisplay
  /dev/sdb: read failed after 0 of 4096 at 0: Input/output error
  /dev/sde: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdf: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdg: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdi: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdk: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdl: read failed after 0 of 4096 at 0: Input/output error
  /dev/sdp: read failed after 0 of 4096 at 0: Input/output error
  --- Logical volume ---
(...)

I don't know what is causing this. Anyone can help me with this problem?

Thank you!
Jordi
