Lost Pools After USB Reinstallion

[robotmonkeys]

So something happened and my FreeNAS box locked up and I did a hard reset after I couldn't connect to it. After that happened, the has got in a horrible state where the FreeBSD boot prompt just sat there outputting a stream of #s and doing nothing. (I could not find any documentation about what that means, and google just gave me more forum posts were people were asking the same question.) Without any better ideas, I decided to install the USB boot drive.

That fixed the boot problem, but of course it lost my configuration information. I didn't think this would be much of a problem since I could just reimport my pool. Unfortunately I can't seem to figure out how to do this. The webui throws up warnings about how I'm about wipe the disks. (I don't want to do that. I assume the data on them is fine.)

Using the root prompt from the webui, `zpool status` just says 'no pools available' and `zpool import -FX MyPool` says 'no such pool available'

Just to be clear. If I use Auto Import from the gui, the drop down is empty (probably because of the 'no pools available' message above). If I go to manually import the the volumes, I see the partitions, but i can't bring them in as ZFS.

Am I screwed? I don't think I should be.

You shouldn't be.

First, go get a beer and relax! Your data is safe unless you installed over your pool drive or something else is VERY wrong.

Second, does your GUI show any disks if you go to the View Disks window? If it does, does it show the number of disks that you expect to be in the system?

Post your system specs and freenas version. :)

 

[robotmonkeys]

It does show all four disks ada0 through ada3.

MB: Asus H871-plus
FreeNas 9.1.1
Is there anything specific you're looking in the system specs? I really think this is just that I'm not using the software correctly.

The four drives were raided 1-0, but I have to admit that I don't remember what was paired with what. It was just the default that the gui picked out. I'm pretty sure not remembering the layout will screw me over, if the raid tries to rebuild.

The irony of course is that this all got screwed up during the first backup. :( Luckily, must of the data could be reassembled if necessary.

naughty naughty naughty....not ECC RAM. :)

Anyway, I agree with CJ, the odds are good that unless you suffered a non-ECC-related catastrophe, you should be OK.

 

[robotmonkeys]

I'm still confused on how I'm supposed to proceed, since the most obvious approach says it will destroy the data. How am I supposed to create a pool without having it reinitialize all the disks in the pool. There should be a way to do it, but I'm not familiar with how to do it, and how to do it in a way that informs the gui.

 

[cyberjock]

Sorry I didn't respond back. Somehow I missed your reply posts. So far so good.

So you will need to follow the FreeNAS manual for importing a zpool(assuming you had a zpool). doc.freenas.org is the manual.

Can you post the output of zpool import and zpool status?

Well that's kind of a problem.

`zpool import` prints nothing, and as I said above, `zpool status` says no pools found.

 

[DrKK]

robotmonkeys, you're making it very hard to help you.

Cyberjock wants to issue the command "zpool import" and "zpool status" on your command-line interface, and tell us what it says back to you.

I did. Twice. http://imgur.com/Ysu0vqw

 

[DrKK]

weird, the line where you said it did nothing was not present when I viewed this thread before...

Sorry.

Well I assume CJ has some ideas...

 

[cyberjock]

Umm... something is VERY wrong.

Post the output of:

camcontrol devlist
gpart status

 

[cyberjock]

Are you running in a VM? Post your hardware specs too please.

 

[robotmonkeys]

1) This is not in a VM.

2) The hardware specs are in post 3 (after which DrKK flames me for not having ECC ram) Again, if there's something specific hardware-wise you want to know about, I'll post more but I think the MB info should be enough.

3) Here are the outputs of the commands

This is the correct number of HDDs, and the partitions don't look wrong. Each one is a 2GB swap, followed by a 2.7TB zfs partition

How much RAM do you have installed? Are you using the x86 or x64 version(please check.. some people install the wrong version and don't realize it).

 

[DrKK]

Sir, your threshold for considering yourself "flamed" seems quite low. :)

 

[cyberjock]

Post the output of gpart list too.

Something fishy is going on here. Normally if zpool import doesn't work that means you are in SERIOUS trouble. Normally this would also be a time to see you have no disk partitions. But since your disk partitions are there and look healthy, it's a little confusing.

"flamed" is easier to spell than "chastised." ;)

It is very odd. That's why I'm here.

OK, well, "flamed", in a forum setting, implies the use of considerable vitriol and effort in deconstructing your intelligence and value as a human being. I was merely clicking my tongue. Doesn't even rise to the level of "chastise" much less "flame". But OK. :)

Try these commands...

sysctl vfs.zfs.vdev.larger_ashift_disable=1
zpool import -D -R /mnt yourpoolname

If that doesn't import do:

zpool import
zpool export yourpoolname

Edit: zpool import -D -R /mnt yourpoolname might throw an error, then you'll have to add -f
