Hello everyone,
Recently I had to set up a large file archive on-a x86 system. The setup
included two HPT374 ATA-RAID controllers which after testing prooved to be
inapropriate (poor performance, buggy drivers provided by the
manufacturer). So I decided to use the controllers only for their IDE
funcionality. After setting up the hard drives (10 Seagate Barracuda.7
7200/2048k cache) and cfdisking them to partition type
Linux-Raid-Autodetect I set-up a raidtab file containing the following:
raiddev /dev/md0
raid-level 5
nr-raid-disks 5
nr-spare-disks 0
persistent-superblock 1
chunk-size 256k
parity-algorithm left-symmetric
device /dev/hdm1
raid-disk 0
device /dev/hdp1
raid-disk 1
device /dev/hdq1
raid-disk 2
device /dev/hds1
raid-disk 3
device /dev/hdt1
raid-disk 4
raiddev /dev/md1
raid-level 5
nr-raid-disks 5
nr-spare-disks 0
persistent-superblock 1
chunk-size 256k
parity-algorithm left-symmetric
device /dev/hde1
raid-disk 0
device /dev/hdf1
raid-disk 1
device /dev/hdg1
raid-disk 2
device /dev/hdi1
raid-disk 3
device /dev/hdk1
raid-disk 4
--
and created the arrays.
After several days of usage of the archive and when one of the arrays
reached 35% of its' capacity I noticed this error:
attempt to access beyond end of device
09:00: rw=0, want=1017335020, limit=625153024
This keeps showing up and I'm worried about data consistency. The
filesystem I use is reiserfs.
Please advise me where could be the problem.
Thanks in advance,
