Get data from freenas8 drive without freenas

[riegersn]

Hey guys, my pc running freenas is shot. Has issues with the older hardware but drives are intact. I bought a device that allows me to pop the Sata drive in and connect to my Mac (10.6) via USB.

When I connect it my Mac says the drive is not readable by this computer. I know the device works as I've used another hard drive successfully.

I installed zfsmac but still is not readable. I have very important documents and other content on these 2 drives that I NEED to get to.

I'm in need of some help here, can anyone assist? Thanks in advance.

UFS Explorer - For Mac/Win/Linux ... Worked for me in a similar situation.

MAC does not support anything close to a recent version of zfs.

you could install a virtual machine host (vmware, virtualbox), create a VM and install FreeNAS and expose the disk to the VM. that would get you your data.

you could also scrap together another computer and install FreeNAS.

you could boot a live disk of Solaris express 11 and read the drives from there.


please let me know if you need more details.

Tried UFS Explorer but since I can't mount the harddrive on the mac the app doesn't see the volume.

Installed solaris express 11 on a vm but can't mount it either. GParted can see the drive but can't detect the filesystem. (screenshot: http://cl.ly/2H3b002E2h300Q290O1m) However in terminal im getting: /dev/dsk/c8t0.... is part of active ZFS pool rpool. Please see zpool(1M).

I hope someone can help, i really need this data and without buying new hardware ;(

 

[matthewowen01]

it looks like the proper format for the disk, 2 GB is setup as swap space on each drive for FreeNAS

did you Import them when you were in solaris?

after it boots, pull up a console and type

zpool import

it should print out the pool name after a little while

then type

zpool import -f YouPoolName

you need the -f to import a pool that was not properly exported.


let us know how that does.

I didn't think Solaris could read GPT partitioned drives correctly? That was the major issue for ZFSguru survivors wanting to jump to a form of Solaris - the way ZFSGuru (and FreeNAS) partitioned the drives wasn't accessible by Solaris.

I might be wrong. I *wish* I was wrong as FreeNAS has suddenly become so unstable for me lately (trap 12 kernel panics under high load) that I've had to go back to ZFSGuru because I don't have spare drives to set up for use with Open Solaris. But that's another story...

i moved drives from my FreeNAS 7.2 box to my Solaris 11 box, I'll try going from 8 to solaris 11, hopefully tonight...

So I've tried this but when I type zpool import nothing is listed. Could this be because the disk is not mounted?

 

[matthewowen01]

could be, but i'm not 100% sure.

sorry i didn't have time to check last night, i'll try and make time tonight.

Matthew any update on this?

 

[matthewowen01]

tried it a few minutes ago and i could not get it to work. i have a few other things to do.

 

[matthewowen01]

ok i tried the some more things and i can say, that zpool import does not pickup the pools properly.

 

[matthewowen01]

i did some checking and i can't get them to detect. i'm filing a bug. you should be able to reinstall FreeNAS temporarily to get your data off.

 

[matthewowen01]

taking foot out of mouth, it's not a bug, FreeNAS uses GPT not MBR, solaris doesn't play nice with GPT, but you can use gdisk to convert from GPT to MBR and mount them under solaris.
