Hi. I have two 70GB drives and a 140GB disk set up in RAID1 across the 140GB drive and a RAID0 built over the 70GB disks. Both the RAID0 and the big disk are quite fast (transfers ~ 110MB/s and 70MB/s) - but the mirror is dead slow. Resync lokes like this: md1 : active raid1 md11[2] sdd1[0] 497856 blocks [2/1] [U_] [=========>...........] recovery = 48.0% (240188/497856) finish=15.6min speed=272K/sec If this configuration unwise in some respect? Plain 2.4.20-kernel with some fixes (ext3 and ptrace bugs).
