pbs hosted in a synology VM and connected to an SMB share on the synology
been working fine for a year
this morning it stopped being able to use the SMB share, reboot of the pbs VM didn't fix, seeing things like this in the proxmox log
thing is it was connnecting just fine at 6am... when it was doing its scrub
after pbs reboot
any ideas?
(and the dialect warning is fine, my synology happily does SMB2.1 and later)
