I use automount with systemd service units (not /etc/fstab) to mount an external BTRFS filesystem (2 drives configured as RAID-1). There is a timeout of 120 seconds of inactivity after which it should unmount. This works *nearly* all the time, but sometimes it doesn't and I can't figure out why. The drive is normally only used at 3am to run a backup script, and logs show that this is working correctly, but when I check in the morning I sometimes find the drive still mounted (shown by 'findmnt') even though nothing is accessing it, i.e. 'fuser' shows nothing and 'umount' succeeds immediately. If it matters, the actual timeout always seems to take 300 seconds. I don't know if this is because BTRFS is keeping the drive alive, flushing queues or whatever. It's not important in itself, just another data point. When I mount the drive manually, the timeout always succeeds (though again after 300 seconds rather than 120). Any ideas? poc _______________________________________________ users mailing list -- users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to users-leave@xxxxxxxxxxxxxxxxxxxxxxx Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/users@xxxxxxxxxxxxxxxxxxxxxxx Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
