Hi all, I have a IX4-200d with 4 x 2TB drives config in RAID 1+0 with a 2.8TB iSCSI drive conected to a Win2008 SRVR
I notice problems accesing the iSCSI drive so i wento to check the NAS and found a faillure in drives 3 and 4!
I´ve replaced both drives and the array autorebuild itself stating all ok...
I then try to conect from the windows server but couldnt initialize the drive and the log stated bad blocks on the nas drive.
Using ssh to conect to the NAS I get:

root@NASYN1:/# mdadm -D /dev/md1

Now in drive management I get Total drive size 9.10TB with 4x1.82TB drives?
I also get USED SPace: 4.63TB!

What can I do to get the data back? Our backups are not fully updated...

It looks like you most likely lost a whole mirror meaning your data is lost.
