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.
