A customer had no more access to the sharespace NAS 4TB after a firmware update. By following a couple of guidelines from the archives here ( http://community.wdc.com/t5/WD-ShareSpace/HOWTO-Sharespace-RAID-5-Data-Recovery/td-p/287736 ) ( http://community.wdc.com/t5/WD-ShareSpace/WD-SHARESPACE-RAID-5-FAILURE/m-p/363255#M3016 )
I’ve used an Ubuntu live cd (usb actually) on a pc where we connected the 4 sata HDD.
The problem was that the raid created with mdadm apparently had no LVM2 file systems.
I was starting to make an image of partitions with dd in order to tinker a bit with other solutions, when I decided to try and mount the raid read-only:
sudo mount -r -t auto /dev/md0 /mnt/raid
I had no warnings so I checked the mount point and… my data were there.
I suppose then that not all the WD sharespace raids …share the same file system configuration.
Check this before starting with other solutions.
