I suspect that PARTUUID=716bb614-cf65-fd46-8012-64377d3b231c is actually just an empty filesystem since you have been mounting PARTUUID=933ac7e1-2eb4-4f13-b844-0e14e2aef915 on top of it for a while. I would suggest the following to resolve it. 1. Mount PARTUUID=933ac7e1-2eb4-4f13-b844-0e14e2aef915 at /home. 2. Mount PARTUUID=716bb614-cf65-fd46-8012-64377d3b231c at /mnt/family. 3. Copy the contents of /home/family to /mnt/family. 4. Unmount /mnt/family. 5. Remove the contents of /home/family. 6. Mount PARTUUID=716bb614-cf65-fd46-8012-64377d3b231c at /home/family. Yes, that's correct, I should have noticed the missing /home/family/lost+found. Thank you. |
I have the following /etc/fstab entries, which work fine: PARTUUID=c12a7328-f81f-11d2-ba4b-00a0c93ec93b /boot vfat umask=0077 0 2 PARTUUID=0657fd6d-a4ab-43c4-84e5-0933c84b4f4f none swap sw 0 0 PARTUUID=4f68bce3-e8cd-4db1-96e7-fbcaf984b709 / ext4 defaults,noatime 0 1 PARTUUID=716bb614-cf65-fd46-8012-64377d3b231c /home/family ext4 defaults,noatime 0 2 PARTUUID=933ac7e1-2eb4-4f13-b844-0e14e2aef915 /home ext4 defaults,noatime 0 2 When I try to swap the /home and /home/family entries to have (more logically) the /home first, the mounting breaks. The /home/family then has only the lost+found in it. When unmounted, the correct directories appear but the partition is no longer listed as mounted. It thus appears that the /home/family has two entities mounted in this case, one of them empty. --------- The output of emerge --info is as follows: # emerge --info Portage 3.0.61 (python
