I searched bugzilla but could not find any complaints about this issue, and since I am seeing it on several different computers, I find it hard to believe that I am the only one seeing it.. I am running openSuSE 11.2, x86_64 on all my systems. I also looked in /var/log/messages but see nothing that indicates a problem.
I have a similar problem but didn't report it for 2 reasons: 1) I can't figure out where the problem is, and 2) (as a result of 1) can't figure out if it is related to some configuration problem I've created. But in my case the outcome is worse -- the system hangs when shutting down. It kills off all processes and goes into the final stages of shutdown -- but hangs before it actually unmounts the disks. It has to be power-cycled -- the result is disk-thrashing. I've lost a software RAID5 array twice, this way (that contained backups). Neither of my hardware RAID5's have been affected. It does indicate to me that Software RAID5 isn't very reliable and shouldn't be used for important data. I have experienced some data loss when some local reconfigurations caused loss of primary data when backups had been on a software RAID5. I'm contemplating how to switch over to hardware RAID5 for my backups so they won't be destroyed so often. But had my systems not experienced the shutdown-reboot problems you mentioned, I might never have noticed a problem with software RAID. FWIW -- if files didn't get written out completely, that'd be 'fine', but to have the arrays fail to be able to be assembled even in degraded mode is unacceptable from a reliability standpoint. -linda -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
