Folks,
This is, umm, odd. Two, at least, and possibly a third over theweekend, of some older Dell 1950's, suddenly died shortly after being upgraded to 5.6. They're all about the same age, and it's not happening with other systems, but they claim a scsi abort, and the f/s goes read-only. The little lcd screen goes orange, and shows a fatal error E 171, and B0 F3 D0? D0 F3 B0? I forget, and won't be able to double check my memory till the morning.
Has anyone seen this, with a f/s suddenly going r/o, on machinesthat seemed to be running fine for years? Since this is two? three machines, that's somewhere between "coincidence" and "enemy action".
Probably a coincidence. Last week, I lost 2 disks in the same system in 2 days. The 2nd time, even if RAID 5 status was optimal, it did not handle the loss of one hard-disk.
We have a bunch of PowerEdge 1950/2950 running CentOS 5.6. No specific problem since the upgrade (I though about an issue with Squid, but no link with the fact that I upgraded to 5.6).
If you have the LCD screen orange, this is an hardware-related issue. Some of them can be prevented/fixed by upgrading firmwares. You can easily upgrade from CentOS using Dell Server Update Utility or Dell Linux Hardware repository.
