Permission issues. Will check the other thread about freenas permission issues.
[WFPDS] 21:54:30 INFO: Puller: final: chmod /mnt/backup/laptop1/Andreas/AppData/Local/Microsoft/CLR_v4.0_32/UsageLogs/.syncthing.Con
nectifyShutdown.exe.log.tmp: operation not permitted
Hm, strange. I’ve configured a new dataset as described in Permission Denied on any path I choose (FreeNAS) - #5 by Jesse_Moore but I still get the chmod errors.
Will try a) storage local to the jail (not mounted) and b) and UNIX dataset later.
Btw: adding logs to syncthing in a freenas jail works by adding /etc/rc.conf.local
syncthing_args="-logfile=/var/db/syncthing/syncthing.log"
