Client in perpetual sync after some specific file system operations

When changing a file with some applications, the Nextcloud Client starts syncing but never stops. Terminating the client and restarting it, then resumes the halted syncronisation and finishes it.

I have failed to keep a log of which applications do this, but Calibre does it persistently:

  • Open Calibre
  • Set it up to use a Nextcloud folder as storage
  • Add a book
  • Close Calibre again

Once my brain gets around to remembering the other programs that do this, I will amend them here. But, in the meantime, I would love to hear if anyone has experienced the same thing or if there is a logging option I may use to get more information.

This behaviour has existed for quite some time.

Nextcloud 31.0.4 on Ubuntu 18.04.1 LTS

hey @thniels

this is just a hunch…

calibre has an included service for serving books etc. which, when running constantly “pings” those files… changings the metadata or something

those changes will the be synced with your Instance.

prefer setting up a books folder for calibre outside of Nextcloud files and then let Nextcloud access that folder via “external storage” using “sftp” or even “sshfs”.

Hunches can be good. I will dig into this. Thanks!
