Pool offline after replacing disk

Disks

 

[sretalla]

OK, very good.

So we're going to start by partitioning the disk ready for use as a pool member:
gpart create -s gpt /dev/ada0 (working under the assumption it's currently not partitioned at all... you may need to do gpart destroy -F /dev/ada0 first if it's not blank)

Then we create the swap and data partitions:
gpart add -s 2G -t freebsd-swap /dev/ada0

gpart add -t freebsd-zfs /dev/ada0

Ok, done,

 

[sretalla]

OK, so now we'll get the gptid of that partition with glabel status | grep ada0

Ok

 

[sretalla]

OK, note down (copy paste to notepad or something) the gptid for ada0p2, we'll use that a little later.

Now we should import the pool.

Let's try first with a normal import (zpool import VOL-1)

I'm expecting this to result in an indication that we'll need to use -f to go ahead, but want to check that first.

 

[Paengaroa]

Ok, it's still thinking.
Issue is I can't copy for some reason,.

You'll need to type it out manually then... not fun.

You could enable the SSH service and then use Putty (assuming you use Windows) which will get you in a terminal window that can copy/paste.

Ok, I'll go manual for now just to be safe.
Is this expected to take a while? It's not broken?

the zpool import should take no more than a minute... with a missing member disk in the pool, perhaps it's doing some extra checks, but that shouldn't mean waiting for a long time.

We can give it a few more minutes, then I think a reboot is the next step if it remains stuck.

Ok ,it says it cannon import VOL-1, one or more devices are unavailable

 

[sretalla]

OK, so the next step is to do it again but with the force switch:
zpool import -f VOL-1

 

[Paengaroa]

OK, so the next step is to do it again but with the force switch:
zpool import -f VOL-1

Ok, and we wait...

 

[Paengaroa]

OK, so the next step is to do it again but with the force switch:
zpool import -f VOL-1

It's said the same thing again

 

[Paengaroa]

Code:

root@freenas:~ # zpool import -f VOL-1
cannot import 'VOL-1': one or more devices is currently unavailable
root@freenas:~ #

 

[sretalla]

OK, so we'll try the last resort...

zpool import -F VOL-1

 

[Paengaroa]

OK, so we'll try the last resort...

zpool import -F VOL-1

Ok, just entered that.
Does the cap F do something different?

 

[Paengaroa]

OK, so we'll try the last resort...

zpool import -F VOL-1

Ok the Pool VOL-1 is online but degraded. Mirror 1 which is supposed to have drives ADA2 and ADA0 is showing only ADA2.
Progress!

 

[Paengaroa]

Should I just replace the unidentified disk with ADA0?

Yes, if that's an option, go for it.
