Cache drive Unmountable: Unsupported or no file system

Featured Replies

Hi

 

I had my unraid GUI unreachable and nothing on the server screen, console disabled and had to restart.

 

A array start I got on my cache drive "Unmountable: Unsupported or no file system"

 

Here is my diagnostic.

Could someone tell me what can I do ?

 

Many thanks

It's been running for an hours and a half and only shows hundreds of dots continuously. Don't know if it is the normal stuff.

This means there's no valid xfs filesystem on that device, post the output of

blkid

and

fdisk -l /dev/sdf

@JorgeB thank you for your help again

It's strange to see btrfs in dev/sdf1 as it was formatted in xfs at install.

 

fdisk -l /dev/sdf gives

After seeing this btrfs word, I stopped array and set the cache drive to file system auto.

Started the array, everything is there again but the cache drive is now in BTRFS.

 

Files are there. Nothing looks corrupted. It's really strange.

 

I'm sure at 1000% to have formatted this cache drive in XFS.

 

Is this a bug ?

 

Thank you @JorgeB for your help and especially this blkid command.

There is no way that Unraid can change the format by itself.  Much more likely that you forgot what format it was in as the default is btrfs.

Hi, I created this cache pool last week because I had issues with btrfs. So, I am sure that this drive was formatted by using WebGUI in XFS. What unraid does for real, I don't know, but I know what I and what was displayed until yesterday on my cache pool line was XFS, not BTRFS.

 

And if it was not formatted to XFS, then why at reboot Unraid tried to mount this drive in XFS ?

If you have explicitly set XFS as the format then Unraid will try and mount it using that format and fail if it is not XFS.

  • Author

Yes indeed.

I dont' know where you want to go saying that but yes.

If I set XFS it mounts as XFS.

But if I format in XFS, manifestly this time there was an issue with formatting and it formatted to BTRFS (what I absolutely wanted anything but not that)

 

We'll see next time, I have to change this drive again next week !

@itimpi I can tell his cache is xfs:
 

Quote

#config/pools/cache.cfg

 

diskUUID=""

diskFsType="xfs"

diskFsProfile="single"

diskFsWidth="1"

diskFsGroups="1"

diskNumMissing="0"

diskAutotrim="on"

diskWarning=""

diskCritical=""

diskComment=""

diskShareEnabled="yes"

diskShareFloor="0"

diskExport="-"

diskFruit="no"

diskSecurity="public"

diskReadList=""

diskWriteList=""

diskVolsizelimit=""

diskIdSlot="-"

diskSize="3907017540"

diskType="Cache"

diskSpindownDelay="-1"

diskSpinupGroup=""

 

The weird part that the diskUUID is missing and should be "7bd58c2e-679a-4d26-8105-134b4913c3f3"

 

@LittleLama would you mind posting your last diagnose with your last time you mount it to double check that?

Same behavior, the UUID is missing from the file at config/pools/cache.cfg

 

At least it has the diskId, but it's kind of weird from my point of view.
