Error when editing MergerFS filesystem

jroch74 · 21. Juli 2022

Hello !

First, thank you for all the great work ! It will be the 8th anniversary of my OMV NAS in october and I rarely face bugs that I can't solve by myself

When I try to edit the "Usage Warning Threshold" value of my MergerFS filesystem, I have the following error :

Code

fsname: The value null is not a string.


OMV\Json\SchemaValidationException: fsname: The value null is not a string. in /usr/share/php/openmediavault/json/schema.inc:370

I have found old threads about similar issues but they didn't help me a lot.

Do you know a way to fix this ?

I will have to look into this. The mergerfs backend is causing this.

Thank you for the reply, I will wait for the fix to come out

Since mergerfs (and remotemount) are using systemd instead of fstab, I guess I could add the setting in the mergerfs plugin. You would have to edit it in the mergerfs plugin. I'm not sure a filesystem usage warning makes sense for mergerfs because all of the underlying drives will have a limit set.

I use this drives as "cache" one day they can be at 5% and the next day at 100%.

The warning is helpful in this case, if I can't have it this way, I will try to have it with another way but I prefer a clean setup and an option directly on the OMV WebUI

I understand. As an example, if the three drives that make up the pool have their warning limits set at 95%, that would be almost the same as the pool having a warning limit set at 95%.

When I said edit it in the mergerfs plugin, that is in the OMV web interface.
