I'm migrating some filesystems from UFS to ZFS and I'm not sure how to create a
couple of them.
I want to migrate /, /var, /opt, /export/home and also want swap and /tmp. I
don't care about any of the others.
The first disk, and the one with the UFS filesystems, is c0t0d0 and the 2nd
disk is c0t1d0.
I've been told that /tmp is supposed to be part of swap. So far I have:
lucreate -m /:/dev/dsk/c0t0d0s0:ufs -m /var:/dev/dsk/c0t0d0s3:ufs -m
/export/home:/dev/dsk/c0t0d0s5:ufs -m /opt:/dev/dsk/c0t0d0s4:ufs -m
-:/dev/dsk/c0t1d0s2:swap -m /tmp:/dev/dsk/c0t1d0s3:swap-n zfsBE -p rootpool
And then set quotas for them. Is this right?
Hi
So zfs root is very different, one cannot have a mix of ufs + zvol based
swap at all.
and lucreate is a bit restricted, one cannot split out /var.
The only one that works is
lucreate -n zfsBE -p rpool
where rpool is an SMI based pool.
To check for SMI run format, select the rpool disk and p, p, then check
if it lists cylinders ( SMI ), if not run format -e on the disk and
label ( delete rpool first if it all ready exists ), then preferrably (
but not necessary ), put all space in slice 0 say ( so that rpool has
the whole disk ).
Post boot of zfsBE, one can modify the swap and dump zvols ( look on
google for zfs root swap ).
Enda
