Cannot change file system on cache drive

Featured Replies

So after a headache trying to remove a ssd from a cache pool, I am now having issues trying to do anything like balancing.

 

Worst part is I cannot even change from btrfs to xfs on the disk. It just shows auto, btrfs, and btrfs encrypted. I thought xfs was suppose to be in there (which I want).

 

On top of that, it's showing 1TB total free space when it should be half of that since I had identical drives.

 

Right now running a balance gives output of:

 

root@Tower:~# btrfs balance start -f -dconvert=single -mconvert=raid1 /mnt/cache
Done, had to relocate 3 out of 3 chunks

How many cache slots do you have allowed?   If it is more than 1 then only BTRFS types are allowed as the other types do not support having a cache pool.

Just 1. Something is wrong, I knew as soon as i saw that balance output.

Please post the diagnostics: Tools -> Diagnostics

So, if you stop the array and on the main page click on cache you can't change the filesystem?

Only btrfs choices.

Weird, with the array stopped edit /config/disk.cfg and change

 

cacheFsType="btrfs" to "xfs"

 

start the array and you should be able to format it xfs.

Stop the array and make sure the number of cache devices is set to 1

So far so good. Back to 1 disk cache with xfs. However, are there any clean up commands I can use on both of my ssd disks(1 cache, 1 unassigned) to ensure no traces of irregularities?

 

Thanks by the way.

Reformatting the disks should effectively erase the current contents.
