One of receiving nodes is “Out of sync”. Now I have only one file in this state. No ignore patterns. Other is fully synced. I had more of those files but when I changed “Out of sync” -files names (only one character), then they synced.
I have tried to read debug logs from both sides (STTRACE=main,model,sync) with no luck.
OK, -reset-deltas solved the issue! Thank you! I walked through several bugs on GitHub and searched forum, but was not sure if this is issue is still going.
Workaround: you can create an (empty) file on sending device with the same name as “outofsync” file on destination device. Then rescan, wait for sync, delete file and rescan again.
