Hi Everybody,
I tried it exactly as Martin says and it works until you try to reboot. On
my Red Hat 9 soft RAID would not be restarted since my entry in fstab is in
the form:
/dev/testvg/mylv /export/home ........
I found the work around for that issue ie: since rc.sysinit looks for md
entry in fstab you need to set INFSTAB variable =1 in rc.sysinit then soft
RAID will start and your LVM file system will be mounted.
Since I'm new to the group I hope I'm not saying obvious things. I only had
to do that to get mirroring since I wasn't able to install LVM2 on Red Hat
9.
Regards
Wojtek
