Hello list members, I'm trying to make software raid working on SATA drives for two days with partial success. I'm using kernel 2.6.5 with Debian.The server has two 160Go drives and i want to make RAID 1 on them. It works partially since the server boot on a raid partition w/o problem. The problem comes when i try to construct RAID 1 array on big partition (it seems to works when partition size is not too big) e.g. /home which is about 140 Go. When i mkraid or raidhotadd, it starts to construct the array and seems to work for some times but fails after an random amount of time. At this moment, disk led shows disks are busy and the system is no more usable (but does not panic since i can magic sysrq to reboot). I tried to use the "standard" ATA drivers. It works, for sure, but performance are really poor. I've also tried to create more little partitions but even with a 70Go partition, array construction fails. Hope you can help, thanks !
P.S. : Do you think I should use iswraid on 2.4.22 kernel ?
