The systemd timer running the `rclone bisync` script is the trigger, disabling the timer leads to no more stuck processes. Thus, it looks like IO usage on the share is the trigger, but only in that context. `rclone` is not reading/writing much data, as there are no differences between the local or remote folders in this case - at most it is issuing a few `stat` calls. I don't seem to be able to reproduce similar hangs by stressing the cifs mount with manual `stat` calls either.
I suspect the kernel might be the wrong bug category for this issue, I am unsure if it would really fit under the kernel, keyutils, or cifs- utils depending on which component is truly responsible for the stall. It is possible that `request-key` (and the subsequent `cifs.idmap` or `cifs.upcall` invocations?) is what is hanging, and the kernel simply does not expect that invocation to take such a long time. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2142726 Title: systemd/pid1 hangs while calling fstat on file in cifs mount To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/2142726/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
