Hi

I'm looking to replace a 2tb disk with a 3tb disk in my RaidZ2 setup to see it increase the pool size (currently have 1x2tb, 2x3tb, 1x4tb) in a HP proliant Gen8 G1610T microserver.

I have a couple of other issues that Nas4Free is reporting, that are outlined in this post:
http://forums.nas4free.org/viewtopic.php?t=11660

Essentially:
- ada1 shows the 4tb disk as a filesystem of "Unknown or unformatted"
- ada1 is not showing in the dvice list for Disks|ZFS|Pools|Virtual Device|Edit
- disks using "non-native block size"

Do I address any of these issues before or after I put the new 3tb disk in?

Thanks!

Not sure if th e screen shot in the previous post shows the data, so another link to the image here on my own site too:

I couldn't see the details in the screenshot too well.

Sounds like all drives are in the same pool so you should be able to replace the old 2TB with the new 3TB. Although since you already have a 4TB might be better to add a 2nd 4TB but that is out of scope here.

zpool replace pool-name old-device new-device
should work

If not post the results and / or consult google

So I keep ignoring the oddities/errors?
And hopefully this screen shot is clearer.

1- first you need to use button "clear config & import disk" this solve your ada1 is not showing in the dvice list
2- you can replace one at time like kenZ1 says.


- disks using "non-native block size" have no sollution other than destroy your pool and recreate new one , this time using apropiate parameter to use native 4k Blok size, but this lose your data, so my suggest is do not change anything here, the performance of use 4k or 512 bit is not great, perhaps 5 to 10%, so no need to start from scrath if you have a lot of data.

1 - ada1 is now showing
2 - I will do this, and not worry about the non-native block size

ada1 does show under
Disks|ZFS|Pools|Information
however, one strange thing remains, ada1 is not showing when I look at
Disks|ZFS|Pools|Virtual Device|Edit

I only have one pool and one virtual device, shouldn't ada1 show there too?

to show in ZFS you need to sync webGUI and reallity in Disks|ZFS|Configuration|Synchronize

Push the button synchronize.

worked perfectly - thanks!

I also discovered that I had 2 more steps needed to allow the pool to expand and utilise the new disk space available:
- set autoexpand to on
- oflline and then online the new disk

After that, the pool expanded to reflect the size of the disks.
