Hi,

some time ago I removed some physical disks from a server and now I'm still getting dmesg messages like:

sd 0:2:2:0: SCSI error: return code = 0x00040001 end_request: I/O error, dev sdc, sector 0

And all lvm tools still grumbel about that disks too:

/dev/sdb: read failed after 0 of 4096 at 0: Eingabe-/Ausgabefehler /dev/sdb: read failed after 0 of 4096 at 1746969493504: Eingabe-/Ausgabefehler

How may I tell the lvm and the system, that it is ok that this disk do not exist any more?

If a software RAID has been removed, don't forget : mdadm --misc --zero-superblock /dev/sdX where sdX is every disk that was part of the RAID.
