Subjectlvm: hw error or misconfig?
Dear developers!

(sorry for the long mail)

We have a compaq proliant server with NO raid and 5 scsi discs:
Host: scsi0 Channel: 00 Id: 04 Lun: 00
Vendor: COMPAQ Model: BD00911934 Rev: 3B02
Type: Direct-Access ANSI SCSI revision: 02

bounded together to a volume group vg00.

This morning we received this strange message, and a file is not readable
anymore. It is i/o error-ed. unfort. this caused loosing important data.

Jan 5 11:30:21 matrix kernel: attempt to access beyond end of device
Jan 5 11:30:21 matrix kernel: 08:31: rw=0, want=8883914, limit=8883913
Jan 5 11:30:21 matrix kernel: dev 3a:00 blksize=1024 blocknr=8551735
sector=17767820 size=4096 count=1

Does it mean that some of the disks are hw errored or is it a
misconfiguration, error in lvm or kernel code?

How could I check the disks while they are in live work?
It would be a big pain to stop the system and reformat the drives, so on.
any idea?

kernel 2.2.17, lvm 0.8i a la debian woody.

thanks for your help, and hoping for fast answer
