I'm using a dual pentium board with 2 233mmx chips. 192mb ram.
I got an oops when trying to attach md2 back to 3 scsi disks.
I have attached /etc/mdtab and the oops trace.
I have raid0, raid1, and raid5 compiled as modules.
/proc/modules:
serial 17632 2 (autoclean)
unix 10484 30 (autoclean)
rarp 2704 1 (autoclean)
3c509 5468 1 (autoclean)
3c59x 17520 1 (autoclean)
ipx 12484 3 (autoclean)
raid0 1696 1 (autoclean)
raid1 6104 1 (autoclean)
/proc/mdstat:
Personalities : [2 raid0] [3 raid1]
read_ahead 128 sectors
md0 : active raid1 sdc1 sdd1 sdc1 1052160 blocks [3/2] [UU_]
md1 : active raid0 sdc2 sdd2 1333392 blocks 8k chunks
