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!

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

What kind of storage do you have?
This might happen if you have an active/passive storage array. The
passive paths won't accept I/O, but will show up in a device list. LVM
(and other processes/threads) tries to do I/O to all devices (unless
they are filtered out in /etc/lvm.conf), and so you get I/O errors.
