I am trying to get RAID 5 up and running under potato. I have four 4.5G SCSI drives (sda-sdd) that were originally set up as a RAID device on this same machine under RedHat. Now, I'm very confused as to whether to use raidtools or raidtools2. raidtools2 says I must patch the kernel, but I can find no patches for the 2.2.17 kernel that comes with potato. I actually hoped that the kernel was already patched since it came with the RAID 5 module.
I have tried it with raidtools and raidtools5. I have the RAID 5 module installed. I get errors about "read_ahead not defined" in /proc/mdstat, and all four devices are listed but show they are not used. Have tried to make the raid device with raidtools and raidtools2. No luck. Not sure I'm doing the raidtools creation correctly, but have created /etc/raidtab from the samples, modified for my configuration. Any help is appreciated. Rod R. W. Rodolico Daily Data, Inc.
