Hello. I'm trying to recover the data from a failed volume on Snap 4500. Server is configured with 4x250 ParalelATA HDDs in RAID0 for approx. 1 TB of space. All available space is configured as one volume.
Yesterday all shares (both SMB and AFP) disappeared. Server boot fine, have access to console, but I see the volume as:
Code:
Name RAID Set Size Mount Point Status Quotas
VOL0 md0 922.50 GB /hd/vol_mnt0 Not mounted Disabled
Also, the Event Log shows thеse errors every two minutes:
Code:

It seems to me it is a software issue (a corruprion in the file system, may be).
Is there a way to retrieve the data on the volume? Again, the OS itself is OK, server boots fine. The data is what is important.
