Server dead. Trying to read drives via Linux fails.

[page3]

A power-cut has taken out my server (even though it has a UPS and surge-protector).

 

The disks were formatted to XFS, directly from UnRAID.

 

I only have access to a Mac, which cannot read XFS so have installed Ubuntu 14 under VMWare.

 

I have an external USB caddy. The drives can show up in 'disks', but when I try to mount them I get the following error:

 

Error mounting /dev/sdb1 at /media/davisa/3e3be4f8-1f83-441c-9630-96eacd67fd5f: Command-line `mount -t "xfs" -o "uhelper=udisks2,nodev,nosuid" "/dev/sdb1" "/media/davisa/3e3be4f8-1f83-441c-9630-96eacd67fd5f"' exited with non-zero exit status 32: mount: wrong fs type, bad option, bad superblock on /dev/sdb1,

      missing codepage or helper program, or other error

      In some cases useful info is found in syslog - try

      dmesg | tail  or so

I thought that array disks would be readable outside the array, am I mistaken or doing something wrong? Help appreciated

What's the output of fdisk -l

[itimpi]

Normally plugging an unRAID disk into a Linux system "just works".

 

What size are the disks?  I have a feeling that VMWare cannot handle disks larger than 2TB.

 

Do you have a DVD drive for the Mac?  If so you might be able to use a Linux 'live' DVD and boot into that instead of Mac OS.  That would bypass VMWare and might be a way of getting at the data on the disks.

Thanks for the advice

 

Disks are WD 2Tb Red's. I'm hoping the issue is with VMware or the external USB caddy rather than any corruption on the drives.

 

I can try fdisk -l tonight (I'm in the UK).

 

I am able to borrow an old HP box from work to set-up a temporary UnRaid server. I'll do some searching here, but assume I can simply boot from my USB install and re-assign the drives etc. This would hopefully be a good way to recover things.

Sounds like you're making tracks in the right direction.  I guess being from the UK explains your username then..... 

 

Whereabouts?  I'm in Staffs...

The Page3 isn't what you think! During my youth my parents ran an out of print book finding service and I was one of four sons. The business was called "The Four Pages" and as the third son I got labelled as "Page 3". Seems to have stuck

 

I *really* hope my disks are OK. I can't see why they're be corrupt. They probably weren't even spun up at the time.

 

I've used VMWare/Ubuntu to read Reiser disks before, but never had to try since upgrading to XFS.

 

Once this is done, I REALLY need to sort a backup solution from UnRAID to a small NAS/USB. I@ve struggled with this for some time and keep giving up. I think this is the one area where the likes of Synology/QNAP do better.

Just to update...

 

I brought back a borrowed pc from work. Can't try UnRAID yet as I need a few more sata cables, which I've ordered.

 

I did however boot up a live Linux distribution and that read the xfs disks just fine. Look like my problem was VMware/Mac related.

 

Will try UnRAID on it once the cables arrive.
