Howdy,
I want to migrate some existing plexes to a different volume than the one that
they are currently a member of. Here's the existing configuration:
V iso State: up Plexes: 2 Size: 4096 MB
V iso2 State: up Plexes: 2 Size: 1500 MB
P iso.p0 C State: up Subdisks: 1 Size: 4096 MB
P iso.p1 C State: up Subdisks: 1 Size: 4096 MB
P iso2.p0 C State: up Subdisks: 1 Size: 1500 MB
P iso2.p1 C State: up Subdisks: 1 Size: 1500 MB
S iso.p0.s0 State: up PO: 0 B Size: 4096 MB
S iso.p1.s0 State: up PO: 0 B Size: 4096 MB
S iso2.p0.s0 State: up PO: 0 B Size: 1500 MB
S iso2.p1.s0 State: up PO: 0 B Size: 1500 MB
D yin State: up Device /dev/ad0s1e Avail: 0/38172 MB (0%)
D yang State: up Device /dev/ad2s1e Avail: 0/38172 MB (0%)
I don't want to have seperate iso and iso2 volumes anymore, I'd like to merge
their plexes into a single volume called iso.
Here's my plan to go about doing this:
* enter vinum interface
* detach -f iso2.p0
* detach -f iso2.p1
* rm -f iso
* attach iso2.p0 iso
* attach iso2.p1 iso
* use growfs on the changed volume
Do I have the logic correct? Are there any potential pitfalls involving
dataloss?
I suspect that I'm missing a step to alert vinum that the new plexes extend the
mirror - and I'm not sure that it can be done without destroying both the iso
and the iso2 volume and recreating the mirror from scratch (thus, dataloss).
Thanks,
-T
