Hi,
My Centos 5.2 server (5.1 suffered the same problem as well) has a
logical volume on a RAID 10 array (4 SATA harddisks on a Highpoint
RR2310 controller). /etc/fstab has an entry for this array as below
/dev/raid_vg0/raid_lv0 /mnt/raid ext3 defaults 0 0
Normally it works OK. But, file system of "this volume" once in a while
goes "read only" mode. The RAID software reports no problem with the
hard disks. After reboot, the system comes back in normal rw mode.
If it happens again, you may be able to avoid the reboot with
mount -o remount,rw /mnt/raid
As to your "how to check production ...", easy. The trade-off (down
time, reboot, ...) makes it easy to decide to knock users down, umount
the FS, run the check, remount, tell users they can go again.
William, thank you for the hint. Nevertheless, the command doesn't
mount rw. It says
mount: block device /dev/raid_vg0/raid_lv0 is write-protected, mounting
read-only
I had to reboot again.
