I setup a raid 5 with 5 18G disks. 3 for data, 1 for parity and one hot
swap. This config file I used is:
raiddev /dev/md0
raid-level 5
nr-raid-disks 4
nr-spare-disks 1
chunk-size 128
parity-algorithm left-symmetric
device /dev/sdc1
raid-disk 0
device /dev/sdd1
raid-disk 1
device /dev/sde1
raid-disk 2
device /dev/sdf1
raid-disk 3
device /dev/sdg1
spare-disk 4
I made the raid, put an ext2 file system on it, and copied about 9gigs of
data to it, then rebooted. After rebooting, we got errors like this:
Data overrun detected in Data-In phase, tag 13;
and
Have seend Data Phase. Length=122880 NumSGs=30
and a few errors with SEQADDR and SAVED_TCL in them.
First question I guess would be, is this a problem with the raid?
If it is, is there a know fix? We were hoping to use a software raid, but
a hardware raid is looking better and better. Does anyone have a
recommendation on a raid controller card?
thanks
