Unmountable: Wrong or no file sysem


Recommended Posts

Hi,

I just tried to add the sdj to my array. It was written "Unmountable".

I remove it from of the array.

In Unassigned Devices, I can't mount or format the disk
I have attached the diagnostic file.

In Unassigned devices I was able to mount the disk and format it to xfs (after 10min...)

I added it to my array

Data-rebuild is in progress...
but in the array devices, still "Unmountable: Wrong or no file sysem" (sysem or system ?)

 

Thank,

Are you sure that Unraid is not ‘clearing’ the disk?    Rebuilding normally only applies when replacing a failed drive.    However, depending exactly on what you did it is possible you have managed to get it into a state where unraid is ‘rebuilding’ a disk containing all zeroes.
 

Normally when you add a new disk to the array Unraid will Clear it by writing zeroes to every sector on the disk so that parity remains valid (which wipes any existing format).    If the drive has been pre-cleared (but NOT formatted) then this clear phase is skipped).  When that completes you then need to format the drive to create an empty file system so that it can be used.

I added the hard drive to the array
Unraid clearing the disk
I received the message "Unmountable", because the file system type was on "auto"
I changed the file system type was to "xfs"
Remove the disk from the array
I did not get a message to format the hard drive

In unassigned devices, Mount appeared and I was able to format it to xfs.

I added the hard drive to the array...

I went there

 

There's the new diagnotics file.

There would have been a button to allow all ‘unmountable’ disks to be formatted in the Array Operations part of the Main tab with the new drive listed as one of the drives to be formatted.


The procedure for adding disks to an array is documented here in the online documentations accessible via the ‘Manual’ link at the bottom of the GUI.

I have a parity drive
I did exactly 1 to 6.
7- Unraid has pre-cleared my hard drive

but it didn't seem to have been formatted

8- ok

9-10-11 ... to be continued

but now, Unraid rebuild the drive. 88,8%
