Can't metattach root partition

Probos · May 28, 2009, 2:47pm

I'm mirroring up a T2000. Able to metainit and metattach all partitions with the exception of root. Getting the following error:

metattach: <hostname>; c1t1d0s0; is mounted on /

I'm stumped. By the way, target 1 is the boot disk.

you can run metaroot to reset the system to boot from volume

eg.

#metaroot d0

Did that prior to trying to attach the mirror.

check the entry in /etc/vfstab and /etc/system if the its there where the volume is mount in those file then reboot the system and try attaching the disk

Question. In /etc/system - the MDD root line:

rootdev:/pseudo/md@0:0,10,blk

The "md@0:0",...do either of the zeros represent what disk is the actual boot disk/device? Either 0 or 1?

As per my understanding, if its md then its mean it meatdevice and its shows that the entry has been placed into the /etc/system to instruct that the root file system is on pseudo file system.

hi,

please show the output

`metastat -p`

and your metattach command

You must do the metaroot command and then reboot the machine before attaching the other half of the mirror to the root device. In most cases people forget the reboot which causes the below error.....assuming everything else is OK.
