SUMMARY: Attempt to remove SDS from root disc caused "mount: /dev/dsk/c0t0d0s0 is not this fstype."

SUMMARY

The reason for the errors was because the default boot disc was set to the
rootmirror (c1t0d0s0) and not c0t0d0s0.
This meant that the vfstab entry for root was incorrect.
Booting from the correct device (and updating the OBP default boot device)
solved the problem.

Thank-you to everyone for theit suggestions.

Dear all,

I have a small problem that has knocked out a domain :(  Has anyone got any
clues on what went wrong, and of course how on earth I mend it.  Myself & a
collegue have spent this morning googeling and looking on the Sun site to
try and work this out but have had no luck.

* Today, I tried to remove SDS from the root & swap partition.   
  I had installed Veritas VM and FS but did not run the vxinstall script

* What I did to remove SDS on root and swap:

metaroot /dev/dsk/c0t0d0s0
checked that /etc/system & vfstab were correct metadetach d10 d12 (the
second mirror of the root disc) dumpadm -d /dev/dsk/c0t0d0s1 (updated
dumpadm)


/etc/vfstab is now:
/dev/dsk/c0t0d0s1       -       -       swap    -       no      -
/dev/dsk/c0t0d0s0       /dev/rdsk/c0t0d0s0      /       ufs     1       no
logging
/dev/md/dsk/d30    /dev/md/rdsk/d30     /export/home    ufs     2       yes
logging
/dev/md/dsk/d40    /dev/md/rdsk/d40     /u01    ufs     2       yes
logging
swap    -       /tmp    tmpfs   -       yes     size=512m


* Rebooted and got it would not mount / other than as a ro device.  Here
follows the output of boot and df:
