I tried that, but I seem to be going backwards. After updatedb the database is almost empty: <terminal> root@barley:~# date; time updatedb Tue 19 Jul 2022 05:09:17 PM PDT real 0m0.259s user 0m0.206s sys 0m0.052s root@barley:~# ls -l /var/lib/plocate/ total 8 -rw-r--r-- 1 root root 183 Nov 17 2021 CACHEDIR.TAG -rw-r----- 1 root plocate 899 Jul 19 17:09 plocate.db </terminal> and even the files I could locate before have vanished from it. I initially tried systemctl start plocate-updatedb.service with the same result. Looking at the diagnostics below it seems that plocate has decided that / is a bind mount, and so updatedb skips it and everything below. The last line is Skipping `/': bind mount But I'm not sure of my interpretation. For example, just above that it says it is adding / and several other paths, but that perhaps means adding it to the list of bind mounts. Note that the final bind mount listed, for bacula.sql, is a single file. Maybe that caused trouble? BTW, the same directory is available in 2 different spots: / and /root/btr02/root. /root/btr02 is a mountpoint; /root/btr02/root is not, though it is a btrfs subvolume. Also note that some other "top level" systems are mounted, e.g., /root/ubuntu, and so there are several directories that play the role of '/' and several that are '/root' when the corresponding OS is active. Maybe if I added some of these duplicates, e.g., /root/btr02/root, to the prunepaths list it would let the remaining one to be indexed? That's a little brittle if I may be mounting and unmounting as I go; some rule like "use the first" (not sure if the order is available) or "use the one in fstab" might be more robust. Ross Diagnostics follow. <terminal> # updatedb --debug-pruning -v Tue 19 Jul 2022 05:10:28 PM PDT conf_block: prune_bind_mounts\000 1\000 \000 prunefs\000 AFS\000 AUTOFS\000 BINFMT_MISC\000 CEPH\000 CGROUP\000 CGROUP2\000 CIFS\000 CODA\000 CONFIGFS\000 CURLFTPFS\000 DEBUGFS\000 DEVFS\000 DEVPTS\000 DEVTMPFS\000 ECRYPTFS\000 FTPFS\000 FUSE.CEPH\000 FUSE.GLUSTERFS\000 FUSE.GVFSD-FUSE\000 FUSE.MFS\000 FUSE.RCLONE\000 FUSE.ROZOFS\000 FUSE.SSHFS\000 FUSECTL\000 FUSESMB\000 HUGETLBFS\000 ISO9660\000 LUSTRE\000 LUSTRE_LITE\000 MFS\000 MQUEUE\000 NCPFS\000 NFS\000 NFS4\000 OCFS\000 OCFS2\000 PROC\000 PSTORE\000 RPC_PIPEFS\000 SECURITYFS\000 SHFS\000 SMBFS\000 SYSFS\000 TMPFS\000 TRACEFS\000 UDEV\000 UDF\000 USBFS\000 \000 prunenames\000 \000 prunepaths\000 /media\000 /tmp\000 /var/lib/ceph\000 /var/lib/os-prober\000 /var/spool\000 \000 ----------------------- Rebuilding bind_mount_paths: `/sys' (22 on 28) is `/' of `sysfs' (0:20), type `sysfs' `/proc' (23 on 28) is `/' of `proc' (0:21), type `proc' `/dev' (24 on 28) is `/' of `udev' (0:5), type `devtmpfs' `/dev/pts' (25 on 24) is `/' of `devpts' (0:22), type `devpts' `/run' (26 on 28) is `/' of `tmpfs' (0:23), type `tmpfs' `/' (28 on 1) is `/root' of `/dev/mapper/btr02_crypt' (0:24), type `btrfs' `/usr' (29 on 28) is `/usr' of `/dev/mapper/btr02_crypt' (0:24), type `btrfs' `/sys/kernel/security' (27 on 22) is `/' of `securityfs' (0:6), type `securityfs' `/dev/shm' (30 on 24) is `/' of `tmpfs' (0:28), type `tmpfs' `/run/lock' (31 on 26) is `/' of `tmpfs' (0:29), type `tmpfs' `/sys/fs/cgroup' (32 on 22) is `/' of `cgroup2' (0:30), type `cgroup2' `/sys/fs/pstore' (33 on 22) is `/' of `pstore' (0:31), type `pstore' `/sys/firmware/efi/efivars' (34 on 22) is `/' of `efivarfs' (0:32), type `efivarfs' `/sys/fs/bpf' (35 on 22) is `/' of `none' (0:33), type `bpf' `/proc/sys/fs/binfmt_misc' (36 on 23) is `/' of `systemd-1' (0:34), type `autofs' `/dev/mqueue' (37 on 24) is `/' of `mqueue' (0:19), type `mqueue' `/sys/kernel/debug' (38 on 22) is `/' of `debugfs' (0:7), type `debugfs' `/dev/hugepages' (39 on 24) is `/' of `hugetlbfs' (0:35), type `hugetlbfs' `/sys/kernel/tracing' (40 on 22) is `/' of `tracefs' (0:11), type `tracefs' `/sys/fs/fuse/connections' (41 on 22) is `/' of `fusectl' (0:36), type `fusectl' `/sys/kernel/config' (42 on 22) is `/' of `configfs' (0:37), type `configfs' `/root/btr02' (91 on 28) is `/' of `/dev/mapper/btr02_crypt' (0:24), type `btrfs' `/boot' (90 on 28) is `/' of `/dev/sdh3' (8:115), type `ext2' `/root/ubuntu' (96 on 28) is `/' of `/dev/nvme0n1p3' (259:3), type `ext4' `/root/ubuntu/boot/efi' (99 on 96) is `/' of `/dev/nvme0n1p2' (259:2), type `vfat' `/root/installer' (102 on 28) is `/' of `/dev/loop0' (7:0), type `iso9660' `/home' (105 on 28) is `/' of `/dev/mapper/vgb2-home' (253:14), type `ext4' `/var' (108 on 28) is `/' of `/dev/mapper/vgb2-var' (253:15), type `ext4' `/var/local/old-bacula' (112 on 108) is `/backup2' of `/dev/mapper/btr02_crypt' (0:24), type `btrfs' `/proc/sys/fs/binfmt_misc' (111 on 36) is `/' of `binfmt_misc' (0:40), type `binfmt_misc' `/run/user/1000' (735 on 26) is `/' of `tmpfs' (0:47), type `tmpfs' `/run/user/1000/doc' (757 on 735) is `/' of `portal' (0:48), type `fuse.portal' `/root/old' (524 on 28) is `/' of `/dev/mapper/old_var' (253:17), type `ext4' `/var/lib/postgresql/bacula.sql' (550 on 108) is `/restore/var/lib/bacula/bacula.sql' of `/dev/mapper/btr02_crypt' (0:24), type `btrfs' Matching bind_mount_paths: => adding `/' (root `/root' is a child of `/', mounted on `/root/btr02') => adding `/usr' (root `/usr' is a child of `/', mounted on `/root/btr02') => adding `/var/local/old-bacula' (root `/backup2' is a child of `/', mounted on `/root/btr02') => adding `/var/lib/postgresql/bacula.sql' (root `/restore/var/lib/bacula/bacula.sql' is a child of `/', mounted on `/root/btr02') ...done Skipping `/': bind mount </terminal>
