2021-08-26 10:37:32: Creating shadowcopy of “var” in indexDirs()
This seems to be the last message w.r.t. indexing. Maybe check (e.g. in htop in process tree view). If the snapshot creation script hangs? Are you using a snapshot script?
root@gandalf:~# cat /usr/local/etc/urbackup/snapshot.cfg
#This is a key=value config file for determining the scripts/programs to create snapshots
create_filesystem_snapshot=/usr/local/share/urbackup/lvm_create_filesystem_snapshot
remove_filesystem_snapshot=/usr/local/share/urbackup/lvm_remove_filesystem_snapshot
root@gandalf:~#

Problem fixed.
It was a hanging NFS mount which was blocking the “df” command.
I detected it by running the lvm_create_filesystem_snapshot script in debug mode.
