I been running syncthing on my Synology NAS ds620slim with 2gb of ram using v1, for a very long time, so I decide to upgrade to v2, after the migration process it seem to work fine until it came to one folder that has just under 30k files using 12tb of data, when It got to scanning this folder, the NAS became unresponsive, to the point I have to power it down, just to get back in again, I have change the setting so it only did one folder scan at a time, and tried again and then this time it seemed to scan OK, it was set to not scan automatically and just use the file watch to update. Then a day later I copied a dozen or some files into the folder, and again the NAS became unresponsive, rebooted and tried again, and it did it again. Having search the internet there were comments about using IONICE on the synology to stop this from happening, but I would have to set this up to run every time the nas / syncthing restarts, which is not really a long term solution. Is there some setting that I’m missing that would prevent syncthing from hogging all the IO bandwidth, and stopping the NAS from doing it’s real job. At the moment I have reverted back to V1 as I need the system running more than I need to be on V2.
