I have run into a snag with a two drive raid1 Appcache while replacing the drive. After combing the forum, i figured I would head the advice of dont do anything and post your diag file first before trying some of the many fixes.

 

Just as a background I started getting alot of SMART errors from the sdg device in the Appcache array. I stopped the arrays, deselected the device from the array, started the arrays and then powered down. replaced the device, powered backup and then added the new device back to the array.

 

And this is where I have left things with a unmountable : unsupported or no file system status for the Appcache array

 

Any insight or advice would be appreciated

According to the diags there are two missing devices from the pool:

 

Nov 11 10:15:54 RUBIX emhttpd: ERROR: cannot read chunk root
Nov 11 10:15:54 RUBIX emhttpd: warning, device 2 is missing
Nov 11 10:15:54 RUBIX emhttpd: warning, device 1 is missing
Nov 11 10:15:54 RUBIX emhttpd: Label: none  uuid: ca2b2eae-7df9-4f81-8471-de925a4d85a2
Nov 11 10:15:54 RUBIX emhttpd:  Total devices 3 FS bytes used 27.70GiB
Nov 11 10:15:54 RUBIX emhttpd:  devid    3 size 232.88GiB used 6.00GiB path /dev/sdf1

 

Do you still have the old device? It will have been wiped but it may be recoverable if otherwise intact.

I still have the device that was showing the smart errors, so your saying the first step is putting it back into the array?

 

I put the original device back into the array and it seems to come up (with same SMART errors). So how do I make sure the RAID 1 mirror is intact and replace the failing device properly?

Got it all sorted and resolved, thanks for the support!
