background: 3 devices worked for a year or more. 1 ARM synlogy linux, 1 amd64 debian, 1 amd64 xubuntu with some sync folders on NTFS external disk. i borked my xubuntu and had to reinstall. my NTFS disk was intact.
after reinsalling synthing 1.1.4, i continuously had sync-conflicts on large 4GB files. i tried syncthing -reset-database which i though was working but in time proved wrong.
i took the NTFS disk and connected to a known good copy (debain) and rsync’ed both ways, deleted sync-conflicts, then remounted NTFS to xubuntu and reset-database again:
#debian machine rsync -avh --exclude=".*" /media/disk2/SYNC/QuadCopter/ /media/user/WD2TB/Computer/SYNC/Quadcopter/ rsync -avh --exclude=".*" /media/disk2/SYNC/YT-Archive/ /media/user/WD2TB/Computer/SYNC/YT-Archive/ rsync -avh --exclude=".*" /media/user/WD2TB/Computer/SYNC/Quadcopter/ /media/disk2/SYNC/QuadCopter/ rsync -avh --exclude=".*" /media/user/WD2TB/Computer/SYNC/YT-Archive/ /media/disk2/SYNC/YT-Archive/ find /media/user/WD2TB/Computer/SYNC -name "*sync-conflict*" -delete find /media/disk2/SYNC -name "*sync-conflict*" -delete #xubuntu machine / remounted NTFS here syncthing -reset-database
waited for 1st fold scan to complete then found this in the GUI yet again: “Out of Sync” … “34 items, ~45 GiB”
it make no sense. this is with the ARM synology disconnected and the two remaining machines that should be exact duplicate copies connected.
v1.1.4 on all ; already “ignoring permissions” on all
