Nothing, or nothing interesting?  I'd expect you to at least see the CWD
of the debug shell.


Got another opportunity, redirected lsof /home and lsof /other to files, and there was no output.

In the past, I've seen lvm2-monitor behave badly in reaction to logical
volumes (block devices) used for VMs that used LVM internally.  Do you
have any logical volumes that aren't used for those four mounted volumes?


No LVM, as mentioned earlier

Several suggestions: Chris suggested that you check "systemctl
list-jobs".  The contents of /proc/mounts might be interesting. I'd run
"lsof /path" where path is the longest mount point path of the volumes
still listed in /proc/mounts.

I did get output from systemctl-list-jobs (edited lightly)
