All data disks 'Unmountable: Unsupported or no file system'

[PFT1]

Server is running 6.12.6. Two parity disks plus eight data disks, all 16TB.

 

Problem occurred after I cancelled a file system check and restarted the array in normal i.e. not maintenance mode. Each of the data disks now has the above error message and all are listed in the Array Operation area as 'Unmountable disks present' along with a 'format' box.

 

The disks themselves appear to be active and operating 'normally'. At this point the system presents two options - format the disks or start a parity check.

 

This is obviously a very worrying scenario so I would appreciate any guidance about how to recover. Diagnostics are attached, thanks in advance.

Reboot and they should come back, also take the opportunity to update to latest stable.

Yes thanks, that worked. Any idea why the system got into that state? Was it something I did? Perhaps aborting the reiserfschk before completion?

Not sure, looks like the disks tried to mount twice, but don't see why, unless it happens again I wouldn't worry.
