Last night, my machine rebooted (possibly due to Evolution locking up -- I don't think it is as stable as Mozilla Mail?) and this seemed to have caused a problem with my software RAID devices md0 and md1.It started "syncing" and the process took hours to do, from around 6:30 p.m. to 4:00 a.m. The physical disks are 2 -- 120 GB Western Digital WD1200JB drives. An Asus DVD drive is connected as /dev/hdb meaning it is the slave drive on one of the IDE busses. Could the RAID array have started syncing according to some schedule that I'm unaware of? Is it normal for software RAID to take the whole darn night to "sync" (reconstruct?) a disk array? I also got these kernel messages: Oct 10 16:40:15 bobcp4 kernel: hda: status error: status=0x58 { DriveReady SeekComplete DataRequest } Oct 10 16:40:15 bobcp4 kernel: hda: drive not ready for command And /proc/mdstat says: [root@bobcp4 root]# cat /proc/mdstat Personalities : [raid1] read_ahead 1024 sectors md1 : active raid1 hda2[0] hdc2[1] 115860416 blocks [2/2] [UU] md0 : active raid1 hda1[0] hdc1[1] 313152 blocks [2/2] [UU] unused devices: <none> [root@bobcp4 root]# Do I have a problem with my drives based on the kernel messages? The mdstat messages? Thanks Bob Cochran Greenbelt, Maryland, USA
