Hi Robert, Not sure what you mean by "this is not the same". Whether the service runs that command or I run it from the cmdline they produce the same results the only difference are those 2 journal messages which only come out when the service runs. I am not having any filesystem problems and running a btrfs device stats as well as btrfs scrub report no errors or issues. I use this system daily for 12+ hours a day so since it first started with TW 20221101 ( 5 weeks ago ) and still exists in 20221202 it seems to reason that if something was really failing it would have failed by now based on all the other times I've ever had a drive fail. Certainly btrfs should be reporting something is wrong. Looking at /var/log/snapper.log ( thanks for that pointer ) I see: 2022-12-04 19:11:11 MIL libsnapper(17833) Snapper.cc(Snapper):130 - subvolume:/home filesystem:btrfs 2022-12-04 19:11:11 MIL libsnapper(17833) Snapper.cc(loadIgnorePatterns):204 -

Not sure if those errors then cause the dbus error exception messages but clearly something in the cleanup process is broken if it is looking for something that hasn't existed in 2 years. Running the following ( from the github link you provided ) snapper -v -c home cleanup timeline Produces no output or errors but if I watch /var/log/snapper.log it gets the following 2022-12-04 19:32:15 WAR libsnapper(18407) FileUtils.cc(SDir):91 - THROW: open failed path:/home/.snapshots/1 errno:2 (No such file or directory) 2022-12-04 19:32:15 WAR libsnapper(18407) Btrfs.cc(checkSnapshot):482 - CAUGHT: open failed path:/home/.snapshots/1 errno:2 (No such file or directory) When you consider that there are no filesystem errors being reported by btrfs ( nor anything else ) and also that the timeline snapshots for the home config are being cleaned up properly it would seem that other than the attempt to access home snapshot #1 which has not existed for 2 years that it is working properly. Any other thoughts? Thanks!
