Greetings. I
am more of a general user than a guru, so please be gentle…I’ll do
my best to describe the issue here. I
have a system running FC11 with five HDDs, ~2 TB of space, all in a logical
volume. It was my presumption that the LVM system functioned sort of like a
raid system (I know you can run striped, for instance). Everything has been running
fine, up until last Monday – I noticed that I couldn’t write to my
samba drive (on the machine in question) – it was read only. I
thought: “Hmm”. Whatever…I rebooted the system, but walked
away (busy) so didn’t watch the reboot process. Came back and did use the
shared samba drive later – but later Tuesday, it went read-only again. OK,
so I started looking around, and it appeared that I had a disk failure from
checking dmesg. Indeed, I could not access anything to write – it was
read only even for root - because SElinux said so…locked up. So…I
rebooted again. One
of the five drives refused to come up – and made a rather ominous
clicking noise – would not initialize. The system would not boot at all.
Would get thru BIOS, pass the ATA card, and then stop. I
pulled the drive out that was bad, dl’d and burned a boot CD-ROM, booted
off of that, and tried to do a restore. I
got an error message: “Error processing LVM. There is inconsistent
LVM data on logical volume _____________. You can reinitialize all
related PVs ___ which will erase the LVM metadata, or ignore which will
preserve the contents.” I
tried ignore first, and it then stated that there were no partitions to mount
(or something – I didn’t write this one down). I
rebooted, mounted read-only this time ( I didn’t want to erase any
metadata) and tried re-initialize – got the same error message again. I
am at a loss as to what to do – I’m thinking that there must be a
way to recover the data on the remaining four drives. Surely this LVM system is
not going to cause me to lose the data on all five drives because one of them
failed? I
would greatly appreciate any help you could give me – I’ve search
quite a bit and can’t seem to fine much in relation to this. It seems
like it would be something that had been addressed…somewhere. Kind
