Ive had to downgrade to resolve this issue.

Post downloading in SAB, i am getting the following error:

Traceback (most recent call last):

File "/usr/lib/sabnzbd/sabnzbd/filesystem.py", line 742, in create_all_dirs

Best bet is to look for the support thread for the container you are using, there may be a known issue with it more recent releases:

Did you find a solution to this? I've just upgraded to 7.2.0 Stable and I'm seeing the exact same issue.

All was working fine under 7.1.4, immediately since upgrading I get the same "cannot create" issue when SAB is trying to save a downloaded file. It also reports that my complete and incomplete download folder "is not writable", even after re-applying the Docker Safe New Permissions and confirming the UID and GID in the docker setup are correct.

Please post the diagnostics to see if it's what I suspect.

Thanks @JorgeB - diagnostics attached.

Logs are being spammed with SSH messages, can't see the actual error, but see if doing a zfs mount -a solves the issue, if yes, it's a known issue and should be fixed for the next release.

Thanks @JorgeB - I can confirm that the zfs mount -a command resolved the issue, SABnzbd is now working as expected again.

zfs mount -a worked for me too

glad we where able to get to the bottom of this./

7.2.1-rc.1 is out, and it should resolve this issue, please retest.

@JorgeB Can confirm, been running 7.2.1-rc.1 for 48 hours and no recurrence of this issue since.

Thanks for testing and confirming.

Running 7.2 and this just recurred for me for the second time.

The solution still works though.
