[linux-lvm] Need to keep running fsck on LVM

[Terry Rigby]

Once a week or so I am getting an issue with my volume where I can no longer 
write to it  and I get "read only filesystem" errors.  I need to unmount it 
and run an fsck.ext3 on it and it will fix errors and then will be fine for 
awhile.  I assume that there is a drive that is dying in the array.  Is there 
any way or telling which drive this might be?

I would think that if you look in the /var/log/messages and/or
/var/log/syslog would give you some indication if there is a hardware
failure building.

Try this:
# grep /dev/hd /var/log/messages /var/log/syslog | more

And see what you get.

Nope, that outputs nothing at all.

I do however see the following in /vavr/log/messages over and over and over 
again...

Dec  1 23:12:46 localhost kernel: attempt to access beyond end of device
Dec  1 23:12:46 localhost kernel: dm-0: rw=0, want=6444890144, limit=905314304

I've had the beyond end of device errors on a regular IDE drive before.
Then they mysteriously went away.

If you find out, let me know.  I was always curious about those.

Have you tried to use smartctl to access SMART data on the drives?

That complaint is from ll_rw_blk.c.  There is probably an application
corrupting your filesystem, or a filesystem bug.
