7.1.4 | Minimum Free Space cannot be set above a certain value

Share "backup". 1TB cache drive + 10TB HDD.

Set min free to 500 GB > Size set is 285.5 GB.

I can go a little above this, but around 380 GB or so, it'll revert to 285.5 GB.

Nothing super in the logs, just:

Jul 22 21:41:59 backup emhttpd: Starting services...
Jul 22 21:41:59 backup emhttpd: shcmd (534): /etc/rc.d/rc.samba reload
Jul 22 21:41:59 backup emhttpd: shcmd (537): exportfs -ra
Jul 22 21:41:59 backup emhttpd: shcmd (539): /etc/rc.d/rc.avahidaemon reload

It's quite irritating because It means OS drive backups from my desktop (typically ~450 GB) will clog the cache, causing the Proxmox backup VM I have there to pause, ruining backup jobs for the cluster, on top of my desktop not getting backed up.

Last attempt was made at 21:44:30. Syslog is flooded with a bluetooth device warning, that's just me forgetting to disable the device on a replacement board that got swapped in yesterday, can ignore that.

Diags attached.
