Are you commited to that controller? Do you have the option of jumpering it to be simple sata controller(s) without using the raid portion, and then using software raid?
No, not easily. I have lot's of data there... BTW, I'm using LVM in between the RAID and the partitions - but that should not make any difference, right?
Should not make a difference as i understand it, although it should not be necessary. Are you sure the raid is not degraded (disk went bad)? Thats too obvious to miss, so I assume its not the case.
The RAID is out only "hard disk". So some part of it is reserved for boot, but rest of the partitions are on LVM so that we can adjust the sizes as needed later on.
No, the hard disks seem fine.
I have situation which is completely different, uses different hardware and disks, but the same effect as you: Write access to my RAID array is about 2mb/s, sequential reads 22mb/s, random reads about 11-12 mb/s. I'm using SuSE 9.2 pro with a Compaq SmartArray 2P / 3200 SCSI RAID controller and a stack of 8 SCSI drives, 18 GB 10,000 RPM. I boot from a separate IDE drive. The raid array is set up as three ReiserFS filesystems each in its own logical volume. I can't explain it. I did finally install a daemon that writes events to the messages log file generated my the RAID controller. But that's specific to the Compaq controller. Do you have something like that for the SATA RAID controller you are using? -T [Men] The Ideal Man should talk to us as if we were goddesses, and treat us as if we were children.
