Two weeks ago I (clean-)installed CentOS 6.2 on a server which had been running 5.7.
There is a 16 disk = ~11 TB data volume running on an Areca ARC-1280 raid card with LVM + xfs filesystem on it. The included arcmsr driver module is loaded.
At first it seemed ok, but with in a few hours I started getting I/O error message on directory listings, and then a bit later when I did a vgdisplay command there was garbage in that.
I then ran the volume check on the RAID card bios, it flagged 3 errors. When I restarted the system, things were ok, but then the problem reappeared. I ran another volume check and no errors were flagged (I should note, the check takes about 9 hours). but upon restarting, the file system was ok, but then went bad again.
Another symptom was that the cli64 raid management utility, which I got from the Areca site would just hang.
After a couple of days of this, I decided I could not afford to have this system unavailable, and I reinstalled CentOS 5.8. Everything has been fine since.
Any body else seen anything like this?
