The device ID of my partition containing my home directory changes (sometimes) when I reboot, typically after kernel updates. Sometimes subsequent reboots with the same kernel change it again, but typically after that it is usually consistent. Changing device ID's causes havoc with tar incremental backups - tar consider all files are new. Is there something I can change to keep st_dev static? I'm running Fedora 33 with my home filesystem as XFS on a LVM supported by md RAID1. I'm not sure if this is caused by LVM or md or something else, hence I ask the experts here. I have a cron job logging the device ID of my home directory at boot with the kernel version, included below. Any thoughts would be appreciated! Thanks in advance. 2021-02-20 22:47 fd03h/64771d 5.10.16-200.fc33.x86_64 2021-02-25 12:59 fd03h/64771d 5.10.17-200.fc33.x86_64 2021-02-27 22:49 fd03h/64771d 5.10.18-200.fc33.x86_64 2021-03-03 12:11 fd04h/64772d 5.10.19-200.fc33.x86_64 2021-03-12 16:25 fd03h/64771d 5.10.21-200.fc33.x86_64 2021-03-16 22:55 fd06h/64774d 5.10.22-200.fc33.x86_64 2021-03-19 14:00 fd06h/64774d 5.10.23-200.fc33.x86_64 2021-03-23 09:35 fd06h/64774d 5.11.7-200.fc33.x86_64 2021-03-28 11:24 fd04h/64772d 5.11.10-200.fc33.x86_64 2021-03-30 17:26 fd06h/64774d 5.11.10-200.fc33.x86_64 2021-04-02 20:11 fd03h/64771d 5.11.11-200.fc33.x86_64 2021-04-14 17:41 fd06h/64774d 5.11.12-200.fc33.x86_64 2021-04-16 17:37 fd06h/64774d 5.11.13-200.fc33.x86_64 2021-04-18 11:58 fd03h/64771d 5.11.14-200.fc33.x86_64 2021-04-22 01:34 fd03h/64771d 5.11.15-200.fc33.x86_64 2021-04-22 01:41 fd06h/64774d 5.11.15-200.fc33.x86_64 2021-04-22 01:42 fd06h/64774d 5.11.15-200.fc33.x86_64 2021-04-22 01:43 fd06h/64774d 5.11.15-200.fc33.x86_64 2021-04-22 01:44 fd06h/64774d 5.11.15-200.fc33.x86_64 2021-04-22 01:45 fd06h/64774d 5.11.15-200.fc33.x86_64 2021-04-22 01:46 fd06h/64774d 5.11.15-200.fc33.x86_64 2021-04-22 01:47 fd06h/64774d 5.11.15-200.fc33.x86_64 2021-04-27 15:18 fd03h/64771d 5.11.16-200.fc33.x86_64 2021-04-28 21:10 fd03h/64771d 5.11.16-200.fc33.x86_64 2021-04-28 21:11 fd06h/64774d 5.11.16-200.fc33.x86_64 2021-04-28 21:12 fd06h/64774d 5.11.16-200.fc33.x86_64 2021-04-28 21:13 fd06h/64774d 5.11.16-200.fc33.x86_64 2021-04-28 21:14 fd06h/64774d 5.11.16-200.fc33.x86_64 2021-05-03 19:23 fd03h/64771d 5.11.17-200.fc33.x86_64 2021-05-08 10:43 fd03h/64771d 5.11.17-200.fc33.x86_64 2021-05-08 10:44 fd06h/64774d 5.11.17-200.fc33.x86_64 2021-05-08 10:45 fd06h/64774d 5.11.17-200.fc33.x86_64 2021-05-08 10:46 fd06h/64774d 5.11.17-200.fc33.x86_64 2021-05-08 10:46 fd06h/64774d 5.11.17-200.fc33.x86_64 2021-05-08 10:48 fd06h/64774d 5.11.17-200.fc33.x86_64 2021-05-11 01:28 fd06h/64774d 5.11.18-200.fc33.x86_64 2021-05-14 22:51 fd03h/64771d 5.11.19-200.fc33.x86_64 2021-05-16 12:52 fd03h/64771d 5.11.20-200.fc33.x86_64 2021-05-16 12:53 fd05h/64773d 5.11.20-200.fc33.x86_64 2021-05-16 12:54 fd04h/64772d 5.11.20-200.fc33.x86_64 2021-05-16 12:55 fd06h/64774d 5.11.20-200.fc33.x86_64 2021-05-16 12:56 fd03h/64771d 5.11.20-200.fc33.x86_64 2021-05-16 12:57 fd05h/64773d 5.11.20-200.fc33.x86_64 2021-05-16 12:58 fd03h/64771d 5.11.20-200.fc33.x86_64 2021-05-16 12:58 fd03h/64771d 5.11.20-200.fc33.x86_64 2021-05-16 12:59 fd03h/64771d 5.11.20-200.fc33.x86_64 2021-05-16 13:01 fd03h/64771d 5.11.20-200.fc33.x86_64 2021-05-20 23:14 fd03h/64771d 5.11.21-200.fc33.x86_64 2021-05-30 22:16 fd06h/64774d 5.11.21-200.fc33.x86_64 2021-06-03 22:19 fd03h/64771d 5.11.21-200.fc33.x86_64 2021-06-03 22:36 fd06h/64774d 5.11.21-200.fc33.x86_64 2021-06-05 14:00 fd03h/64771d 5.11.21-200.fc33.x86_64 2021-06-20 22:32 fd03h/64771d 5.11.21-200.fc33.x86_64 2021-07-05 18:47 fd03h/64771d 5.11.21-200.fc33.x86_64 2021-07-28 17:53 fd03h/64771d 5.13.4-100.fc33.x86_64 2021-08-02 16:05 fd03h/64771d 5.13.4-100.fc33.x86_64 2021-08-02 16:30 fd03h/64771d 5.13.4-100.fc33.x86_64 2021-08-10 08:31 fd06h/64774d 5.13.8-100.fc33.x86_64 2021-08-18 21:13 fd03h/64771d 5.13.10-100.fc33.x86_64 2021-08-22 00:17 fd03h/64771d 5.13.12-100.fc33.x86_64 2021-09-16 07:04 fd06h/64774d 5.13.12-100.fc33.x86_64 2021-09-16 07:27 fd06h/64774d 5.13.15-100.fc33.x86_64 2021-09-25 12:41 fd03h/64771d 5.13.16-100.fc33.x86_64 2021-10-06 14:34 fd06h/64774d 5.14.9-100.fc33.x86_64 2021-10-06 14:35 fd06h/64774d 5.14.9-100.fc33.x86_64 2021-10-06 14:37 fd06h/64774d 5.14.9-100.fc33.x86_64 2021-10-16 10:59 fd06h/64774d 5.14.11-100.fc33.x86_64 2021-10-19 14:54 fd03h/64771d 5.14.12-100.fc33.x86_64 2021-10-19 14:57 fd03h/64771d 5.14.12-100.fc33.x86_64 2021-10-19 15:00 fd03h/64771d 5.14.12-100.fc33.x86_64 2021-10-19 15:02 fd03h/64771d 5.14.12-100.fc33.x86_64 2021-10-22 11:44 fd03h/64771d 5.14.12-100.fc33.x86_64
