Devices out of sync but not relly

[LubosKolouch]

I have 2 devices syncing a folder “Maildir” between each other. Both on Arch Linux 64bit, syncthing 1.5.0

On both devices the folder is shown as up-to-date.

But in the devices list, both show 1: Out of Sync Items | 50 items, ~31.4 MiB 2: Out of Sync Items | 53 items, ~31.4 MiB

If I check what they are, seems they are waiting for each other:

dev1:

Path	Size	Mod. Time	Mod. Device
.Archive/tmp		2020-05-15 10:12:30	dev2

dev2:

.Archive/tmp 2020-04-04 14:41:21 dev1

If I delete the folder .Archive/tmp, it does not help - it is correctly synchronized between the devices, but they stay out of sync.

Expected behavior:

The devices are not shown as out of sync.

Did you try searching existing threads for a solution?

[LubosKolouch]

Yes even some reddit discussions from Google search.

[AudriusButkevicius]

Presumably you tried delta resets and metadata recalculations?

[LubosKolouch]

syncthing -reset-deltas reduced the problem to 6 (9 on the other) items, but not fixed. How to do metadata recalculations?

Up to date but not syncing

This looks more like a problem with the new need metadata accounting: The numbers in the remote devices section are based on that and the actual list is obtained directly from db. In your case they apparently don’t match. That change was introduced in v1.6.0-rc.1 and I don’t have such problems. And unless you find a way to reproduce it I don’t see how to debug this. The relevant debug facility for this is db. If you run with STRECHECKDBEVERY=1s, does the problem go away?

[LubosKolouch]

Yes, it indeed helped!
