Thanks for the many responses, everyone. Just so you know, the reason
I am creating a raid on a single disk is because I am testing the
raidtools before I put it on some larger file servers. I have run
into a new problem now. When I run raidstart I get an error. I first
created /etc/raidtab. I ran mkraid /dev/md0. I did a mke2fs -b=4096
/dev/md0 . All of this appeared to work fine. I mounted /dev/md0. I
copied data to it. I unmounted /dev/md0, stopped the raid, and
rebooted the machine. Now I get this error:
[root@cwb-fs raidtools-0.90]# raidstart -a
/dev/md0: Invalid argument
[root@cwb-fs raidtools-0.90]# raidstart /dev/md0
/dev/md0: Invalid argument
Any ideas? I am running the raidtools from the
raidtools-19990421-0.90.tar.gz tarball.
Thanks
