[linux-lvm] pvscan/vgscan/lvscan error

[Jordi Prats <jprats cesca es>]

Hi all,
I've found that all vgscan is giving me an error. This is the output:

# vgscan -v
   Wiping cache of LVM-capable devices
   Wiping internal VG cache
 Reading all physical volumes.  This may take a while...
   Finding all volume groups
 /dev/dm-4: read failed after 0 of 4096 at 12989693952: Input/output error
 /dev/dm-4: read failed after 0 of 4096 at 0: Input/output error
   Finding volume group "padicat"
 Found volume group "padicat" using metadata type lvm2
   Finding volume group "vg_bbdd"
 Found volume group "vg_bbdd" using metadata type lvm2
   Finding volume group "vg_ordal"
 Found volume group "vg_ordal" using metadata type lvm2

Any idea what this "Input/output error" on /dev/dm-4 does it means? What 
is causing this error?

Thank you!
