Have any of you seen a problem with disks stopping communicating, but when the system is turned off for a while and turned back on, they work again? The initial symptoms we saw was that oracle was not working properly. Then we noticed that while df showed paritions mounted, all partitions associated with a given disk actually would give input/output errors when you would try to touch them. The 'ls' command would return nothing while the 'df' command showed tons of space used. I'm using SuSE 7.0. The hardware is HP Vectra VL. I've seen this problem with various PCs. Once the PC is turned back on again, the disks continue to work for a long time with out problems. Is this definitely hardware related, or is this a communication problem with the disk and OS? thanks for your help, Walter
I do not know if it matters, but every time I have seen this occur, it has only been on disks that have oracle installed and running on them. Walter Walter Moore wrote:

I have had these symptoms, but w/o oracle. I have an IBM 32gb 5k drive that I finally unplugged. It would be OK after ~10 min cold and boot. Might be OK for 3-4 days, then would not allow access to any files. Still showed as mounted but empty, . & .. Would not allow any access and did not affect anything else that I could see. If i umount, then the drive would show as not available or too many xxx, etc. I finally just gave up. I have heard that the IBM 32gb drives had problems ?? -- Patrick Shanahan Registered Linux User #207535 @ http://counter.li.org
That's the same problem I am having. In this case, the disks are Maxtor 53073U6. SuSEnixER wrote:

Just a thought, but are the drives overheating? Is there adequate ventilation? I am probably on the wrong track but sometimes the most simple things.....
