Jesse,
Thanks for responding. This is definitely a learning experience :-)
Here is the contents of my /etc/raidtab file:
raiddev /dev/md0
raid-level 1
nr-raid-disks 2
chunk-size 64k
persistent-superblock 1
nr-spare-disks 0
device /dev/sda1
raid-disk 0
device /dev/sdb1
raid-disk 1
raiddev /dev/md1
raid-level 1
nr-raid-disks 2
chunk-size 64k
persistent-superblock 1
nr-spare-disks 0
device /dev/sda2
raid-disk 0
device /dev/sdb2
raid-disk 1
And here is what the filesystem looks like:
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/md0 31994832 2911144 27458320 10% /
none 256612 0 256612 0% /dev/shm
/dev/md1 2521952 673612 1720228 29% /var
/dev/tmpMnt 1968528 8892 1859636 1% /tmp
Any ideas? Thanks for the help,
Peter
