Hi,

I have a NAS iomegaStoreCenter ix2 with 2 disk of 2Tb with a RAID 1 option enabled.
Some days ago the NAS unit loss the power conection and when the power supply back and the NAS restarted I cannot access to the data. I can enter to the disck via internet conections and the disk cannot obtain ip directions. I can see the folders, but I cannot see the files.
I put both sick on my computer, conected via SATA and mount the RAID with Ubuntu. In this way I can see the filesistem of the disks (a partition of 20 Gb) but I cannot access to the data.

This is the information of

fdisk -l
cat /proc/partitions
lvscan

I really need to acces to some data stored on the NAS unit, or at least I need to know if I loose the data.

Thanks!
