Hi, I am doing some tests with raid. I will probably have more posts on other situations, but here is a situation that causes raid problems... scenario: 1) mkraid /dev/md/0 # raid5 three drive, no spare (using devfs) 2) Wait for resync to complete 3) Disable one of the drives. 4) mke2fs /dev/md/0 Environment: PC + Linux 2.2.2pre2, + raid 19990128 patch + devfs + (out of memory patch) + sym53c8xx scsi driver. The mke2fs process starts queuing *many* scsi requests before the first request fails on the crippled device. Each of the queued scsi requests fails and starts a scsi bus reset cycle and the raid driver spits out its * <COMPLETE RAID STATE PRINTOUT> * with other things and somewhere in there is a program bug message. The scsi reset cycle is over a second and there were perhaps 150 or more queued items. It took a while before the system gave up on the mkfs process. After that, things worked okay in degraded mode. Can't the raid driver de-queue any requests it has for a device it has marked bad? In my case, the raid driver apparently re-issued the device requests for the same blocks to the other good drives. This eventually ran out of memory which terminated the mke2fs. I don't mind this happening to mkfs, but it may happen to something else much more critical. Note: since I have devfs in raid5.c, the line number 666 (I didn't make that up,) is probably different than the standard code. The message is coming from a MD_BUG message within the raid5_error() routine. <>< Lance. Log of some of the bad activity....
