As it seems that there are a lot of them in your case, I’d suggest that you simply remove and re-add the folder in Syncthing on each device. You can keep the actual files on the disk. Just make sure that all devices run v1.27.6-rc.1 before trying to do anything, as otherwise you will likely end up with new files getting stuck anyway.
Wow! Thanks so much for the prompt and comprehensive answer! I really appreciate it.
I am very scared of removing folders from synching and re-adding them. I worry something bad will happen, or that the ‘wrong’ system will be the source of truth, and stuff will get wonky or lost.
No need to remove and re-add the entire folder, resetting delta indexes (`–reset-deltas’) should do it. At least if the issue fixed in the latest RC is the culprit.
Thanks for the tips. I grabbed 1.27.6-rc1 on all machines then did a --reset-deltas from one of them, and now everything is back in sync. Thanks everyone!
