A significant portion of my files are now “Out of sync”.
I’m using Syncthing on two Macs and fsync() on iPhone and iPad. When other devices are connected, Syncthing on the main Mac shows random sync percentages for devices, like -72%.
Having all devices online has not solved the problem; they sync for a while, then stop, then sync again, number of out of sync files changes from 7000 to 32000 (out of 21k total!), then drops to 6000, but never to zero. I don’t really understand what’s going on anymore.
Here are examples of log entries:

Oh, right, sorry.
Mac OS X 10.11.6, Syncthing 0.14.4 on both Macs
faync() 1.8.1 on two iOS devices
One shared folder, .stignore contains one entry: (?d).DS_Store
Master is not set
Connecting/disconnecting all devices for a while finally brought the number down to 0.
But still, thousands of files (that were not changed) become out of sync for extended periods of time when connecting devices - is it normal or should I check something?
Negative percentages in sync status and number of out of sync files being higher than the total number of files seem like bugs; let me know if I should get an extended debug info for you next time I see this.
Uhh, I think fsync() probably doesn’t handle delta indexes well. We can only go as far as debugging syncthing, not fsync, as it’s closed source and not maintained by us.
I’m not entirely sure, but I think I’ve seen similar behavior before I linked fsync(). One of the computers just flags the entire folder as out of sync for a few seconds even though the real difference is <10 files.
