I have just upgraded from F25 to F26. When I plug a usb external disk and I mount it through thunar, it works fine. However, when I try to unmount it, it takes ages until the unmounting is completed. If I unmount the external disk by using the terminal, the unmounting is immediate -- therefore the problem is thunar's. Thanks, Paul

Would one of you be willing to file this upstream at bugzilla.xfce.org? I cannot seem to duplicate it here. ;(
Should verify that this is the same bug. Can you try strace-ing the thunar process, to verify the same observations I made in my bug. Also, the fact that the same exact version of Thunar on F25 was fine.

You captured too much data. Your strace ends with a poll of four low-numbered file descriptors; 3, 4, 5, and 6. But searching through this, I do see the same bug in your strace. Several instances of this: eventfd2(0, EFD_CLOEXEC|EFD_NONBLOCK) = 21 futex(0x55b9dd02d0d8, FUTEX_WAKE_PRIVATE, 1) = 1 futex(0x55b9dd037a20, FUTEX_WAIT_PRIVATE, 2, NULL) = -1 EAGAIN (Resource temporarily unavailable) futex(0x55b9dd037a20, FUTEX_WAKE_PRIVATE, 1) = 0 poll([{fd=21, events=POLLIN}], 1, 24998) = 0 (Timeout) It created a new event file descriptor, then sat on it until poll() timed out after 25 seconds. This pattern gets repeated several times. So this is the same bug.
Thanks, Sam.
Thanks for filing upstream. Hopefully we will get it sorted out soon.

This message is a reminder that Fedora 26 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 26. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '26'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 26 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
This issue is fixed in Fedora 27. One interesting thing for anybody that still has this issue is that one of my Fedora 27 machines still has the issue. It looks like some leftover configuration setting though, because it only manifests with one account. If I create a new account, then umount starts to work instantaneously. I still haven't identified what exactly has to be clean-up to get it working though :( I'm still resisting the urge to wipe the whole config.
