I mirrored these partitions on my boot drive to my 2nd. internal disk
/
/var
I ran the bootmirror command on the / partition only.
I manually changed the /etc/vfstab file to have /var mount
onto the /etc/md device and I commented out the /var entry
that was mounting on the /dev/dsk/c#t#d#. I did this right after
I issued the metainit commands to create the concat/strip and then
the metainit -m to attach them for var.
When I rebooted the computer /var would not mount. I received
this error
"inconsistency please run fsck manually"
When I ran fsck on the var slice I received this error
"bad super block use alternate"
When I tried to fsck using an alternate I got the same error and
nothing worked.
I had to re-install the OS.
My question is there a certain procedure for unmounting /var
from it's /dev/c#t#d# over to /dev/md? Should I have brought
the system down to single and then manually tried to remount
it onto the /dev/md? Is it ok to create the strip and mirror
on a mounted /var partition?
Any help would be great.
