Problems growing ZFS Volume. Volume does not exist?

[mightymouse2275]

Hey all,

I am new to FreeNas and new to the forums.
have been browsing online for an answer to my issue but have not found it. Maybe my Google-Fu is not so good. I figured I would ask the experts!

Currently I am running FreeBSD 8.2-RELEASE-p1 / FreeNAS Build 8.0-amd64

I have a Zvol named DVD. It is composed of 6 1TB SATA drives (ada0 - ada5). It is a raidz1 volume.

I am now starting to run out of space and I would like to expand this volume. I understand that an existing vdev cannot be expanded, but that a new vdev can be added to the pool to make the volume bigger.

I log into the GUI and follow the steps ** Create New Volume---> Name it the same as the existing volume----> add new disks (ada6-ada10 and ada12).
This completes successfully according to the GUI however there is no increase in volume size.

I logged into the console and performed a zpool status:

freenas# zpool status
pool: dvd
state: ONLINE
scrub: none requested
config:

NAME STATE READ WRITE CKSUM
dvd ONLINE 0 0 0
raidz1 ONLINE 0 0 0
ada0 ONLINE 0 0 0
ada1 ONLINE 0 0 0
ada2 ONLINE 0 0 0
ada3 ONLINE 0 0 0
ada4 ONLINE 0 0 0
ada5 ONLINE 0 0 0

I then test to see if I manually add the disks, what the volume will look like:
freenas# zpool add -n dvd raidz1 ada6 ada7 ada8 ada9 ada10 ada12
would update 'dvd' to the following configuration:
dvd
raidz1
ada0
ada1
ada2
ada3
ada4
ada5
raidz1
ada6
ada7
ada8
ada9
ada10
ada12

Everything looks good, so I attempt the addition and get the following message:
freenas# zpool add -f dvd raidz1 ada6 ada7 ada8 ada9 ada10 ada12
cannot add to 'dvd': no such pool or dataset.

Funny.....I know it exists because I can see it!!!!!! I have data on it and can access the data.

Any ideas on how to get this expanded?

Thanks!

Nobody has any ideas as to why it says the pool is not there when it clearly is? Any suggestions as to what I should be checking?

I would recommend you upgrade to 8.0.1-RC1 as this should fix an awful lot of bugs in the FreeNAS 8.0-RELEASE. Creating a pool with "stacked" vdevs should now work as I created such a zpool (2x4-disk RAIDZ1 vdevs) using just the GUI.

Agree with the suggestion to upgrade to the latest, greatest. But:

Why are you using "-f" in your add? To circumvent some other problem?

What I'd try:

create a pool with just your new drives in
fill it and scrub it (I wear a tinfoil hat, you can probably skip this step if you don't)
destroy it
try again adding the drives to your old pool

FWIW. YMMV.
