Hi,
I am trying to build a RAID 1 with two disks on a new system. Linux is
Debian potato, kernel 2.2.16 patched with raid-2.2.16-A0, raidtools
built from raidtools-dangerous-0.90.20000116.tar.gz.
Partitioning and raidtab follows:
|haber@gwen[6/57]:~$ sudo fdisk -l
|
|Disk /dev/hda: 255 heads, 63 sectors, 2501 cylinders
|Units = cylinders of 16065 * 512 bytes
|
| Device Boot Start End Blocks Id System
|/dev/hda1 * 1 2501 20089251 5 Extended
|/dev/hda5 1 31 248944+ 83 Linux
|/dev/hda6 32 37 48163+ 83 Linux
|/dev/hda7 38 2501 19792048+ fd Linux raid autodetect
|
|Disk /dev/hdb: 255 heads, 63 sectors, 2501 cylinders
|Units = cylinders of 16065 * 512 bytes
|
| Device Boot Start End Blocks Id System
|/dev/hdb1 1 2501 20089251 5 Extended
|/dev/hdb5 1 31 248944+ 82 Linux swap
|/dev/hdb6 32 37 48163+ 83 Linux
|/dev/hdb7 38 2501 19792048+ fd Linux raid autodetect
|haber@gwen[7/58]:~$ cat /etc/raidtab
|raiddev /dev/md0
| raid-level 1
| nr-raid-disks 2
| nr-spare-disks 0
| chunk-size 4
| persistent-superblock 1
| device /dev/hda7
| raid-disk 0
| device /dev/hdb7
| raid-disk 1
|haber@gwen[8/59]:~$
However, when I finally try to build the RAID, this is what happens:
|haber@gwen[8/59]:~$ sudo mkraid /dev/md0
|handling MD device /dev/md0
|analyzing super-block
|/dev/hda7: device too small (0kB)
|mkraid: aborted, see the syslog and /proc/mdstat for potential clues.
|haber@gwen[9/60]:~$ cat /proc/mdstat
|Personalities :
|read_ahead not set
|unused devices: <none>
|haber@gwen[10/61]:~$
Nothing is written to syslog.
I made the partitions smaller (2 GB each), and get the same error
message.
Can anybody please point me in the right direction to get my RAID
working?
Greetings
Marc
