Unmountable: no File system. Format doesnt do anything

[pago]

Wanted to try unraid for Gaming VM.

Build Array with 4 TB parity, 2 TB Array, 1TB SSD Cache.

Installed VM and Windows.

 

After fiddling with Windows VM and GPU Passthrough (didnt know my GPU Bios), i restarted my Server several times.

Now it:

- cant mount 2TB array anymore

- libvirt failed (but thats a secondary/follow up problem, i think).

 

To keep it simple, i wanted to start new, so tools > new config (as there are still no important data on all Disks).

Assigned now only Array and Cache.

Still unmountable.

Formatting 2 TB... no error, but still unmountable.

 

looked into Smart, telling me:

197	Current pending sector	0x0032	200	200	000	Old age	Always	Never	1

Smart short test and smart extended test fails, always with same error as above.

 

I just dont get it, i just want to build simple array and start gaming on Windows VM.

Please post the diagnostics after a format attempt: Tools -> Diagnostics

Diagnostics directly after formatting.

That disk is failing:

 

197 Current_Pending_Sector  -O--CK   200   200   000    -    1

As written in my first post. 
can i fix that?

 

2TB drive was in 2 other raids and never failed or had smart errors. 

[JorgeB]

Disks can fail at any time, you can write zeros to the entire disk, it might fix it, but possibly only temporarily, use for example pre-clear, then run a read test or and extended SMART test.

syslog is filled with errors, eg:

If this is a new build, check all your cabling, power, etc.  Maybe move drive to a different controller or port.

detached the 2TB drive.

Now it seems to work.

 

libvirt online again, all shares now there again.

VMs there and starting.

i experiment a little longer and look for errors in diagnostics.

Thanks.
