Am trying to mount a sdx2 partition that is LVM and save the data on it - my unraid rc12 - saw the drive this time and am trying to mount it and copy off some mysql databases and other files.

 

Is this even possible using unraid to manually mount it somewhere to acess it

 

I get the following when trying to mount:

 

mount: unknown filesystem type 'LVM2_member'

 

Thanks

Right unRaid doesn't include any of the LVM stuff, you might have better luck booting some other linux live-cd or live-usb disk.

will have to try a rescue usb image, but i am afraid that the MB wont see it again after I reboot...

 

Thanks anyways

...boot with a Centos or FedoraCore Live Edition - will work from USB or CD/DVD-ISO.

 

The Disk-Utility would allow you to manage and mount all disks you need, inlcuding LVM based ones..

I'd mount the LVM based disk and another unRAID disk (like cache or one not part of the array) and then transfer files.

Then reboot to unRAID and transfer into the array.

If the drive is failing, use ddrescue to copy an image of the failing drive to another drive.  This also gives you the ability to make a backup copy of the image file before you attempt recovery of the files.  I don't know if ddrescue is included in unraid or not, but any linux rescue livecd distribution should have it.

Look into RIP Linux. This is what I used. I believe it had ddrescue on it.
