[OMV 6.x] MERGERFS - Getting error when editing a pool in WebUI

Hi,

I created a mergerfs pool.

Now, when I try to edit it in the WebUI, I got a "500 - OK" error pop up:

Hereafter the full error stack:

Failed to execute XPath query '/config/services/mergerfs/pools/pool[uuid='b5fcc760-f23e-4b19-b360-cba52d31aabb']'.

OMV\Config\DatabaseException: Failed to execute XPath query '/config/services/mergerfs/pools/pool[uuid='b5fcc760-f23e-4b19-b360-cba52d31aabb']'. in /usr/share/php/openmediavault/config/database.inc:88

#8 {main}

I did try to restart the MergerFS pool, but got the same "500 - OK" error in the WebUI, but quite different stack trace:

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LANG=C.UTF-8; export LANGUAGE=; systemctl restart srv-mergerfs-union\x2d1.mount' with exit code '5':

#4 /usr/sbin/omv-engined(537): OMV\Rpc\Rpc::call('Mergerfs', 'restartPool', Array, Array, 1)
#5 {main}

Nonetheless, the MergerFS pool seems to be created and accessible at /srv/mergerfs/union-1 :

Any idea of what can be the issue?

Hi,

Zitat von chente

I would try creating a group with a name that begins and ends with alphabetic characters (not numbers) and would not include that hyphen in the name. These things usually cause problems.

Zitat von ryecoaaron

And yes, the dash/hyphen is the problem

Indeed, the dash/hyphen was the root cause of my issue. I renamed my mergerfs share as union1 rather than union-1 and it worked.

Why did you add category.create=mfs to the options?

Because I did a dumb copy/paste from the mergerfs Github documentation (I have a torrent client writing on the mergerfs share):

May I ask which option from the dropdown list should I pick to remove the category.create=mfs from the options?

Thanks for your help!

Best regards,

PS: I'm tagging this thread as resolved as the initial issue (mergerfs one) is now solved.
