Mergefs: Couldn't extract an UUID from the provided path ...

jkaberg · 24. Dezember 2016

Happy christmas everyone.

Yesterday I got around to reinstalling OMV to 3.0.57 and setting up mergefs with a bunch of drives, but whenever I navigate the web ui where it maps the mergefs mountpoint (eg. in NFS, Samba or Docker plugins) I get the following error

Code

My fstab looks like this

Code

Anyone with any ideas as to why this is happening? or is it a bug?

,fsname=xfiles

Why are you setting this in options? This seems to be the problem.

Ah yes, that was the problem indeed.

I used to use this cause it helps formatting df output;

without fsname=XXX

Yes, ran into the same problem. OMV should really try to work around having fsname included as it really helps 'df' output.

Mergefs: Couldn't extract an UUID from the provided path ...

Jetzt mitmachen!
