Hi I'm troubleshooting an issue at work where our BackupPC4 Server showed logs about missing pool files. The Server is baremetal, has 32GB of RAM and 8 Cores.
A day after a scheduled reboot of the server during a regular maintenance we start noticing the "missing pool file" messages in the logs. 2021-04-23 01:00:00 BackupPC_nightly now running BackupPC_refCountUpdate -m -s -c -P 7 -r 128-255 2021-04-23 01:00:00 BackupPC_nightly now running BackupPC_refCountUpdate -m -s -c -P 7 -r 0-127 2021-04-23 01:00:00 admin1 : __bpc_pidStart__ 18306 2021-04-23 01:00:00 admin : __bpc_pidStart__ 18307 2021-04-23 01:00:44 admin1 : BackupPC_refCountUpdate: missing pool file 81e5e7a28a0f857827a9c2de6099875601 count 1 2021-04-23 01:01:18 admin1 : BackupPC_refCountUpdate: missing pool file 83b7b97de222ecb2f2a129233d63bad801 count 1 2021-04-23 01:01:18 admin1 : BackupPC_refCountUpdate: missing pool file 82020853cb8c2718ac4ed58b2541c58c01 count 1 However the shutdown of the server during the maintenance was clean and BackupPC exited with exit-code 0 and no apparent job running. 2021-04-22 18:17:11 Got signal TERM... cleaning up (exit code = 0) 2021-04-22 18:19:34 Reading hosts file 2021-04-22 18:19:34 BackupPC 4.4.0 (Perl v5.16.3) started, pid 887 2021-04-22 18:19:34 Next wakeup is 2021-04-22 20:00:00 In total I have 56 entries of missing pool files in my logs. With a quick script we managed to find the files that are missing from the pool. The missing pool files all stem from 2 servers (out of 81) and there from 3 different backups. All missing files are quite similar and are located within /usr/lib/modules/4.18.0-240.22.1.el8_3.x86_64/kernel/drivers/ so somehow related. Does anyone have an idea what could have led to those files being missing from the pool? Is there any way to add those files back to the pool to get rid of the messages in the log. The files are still present on the servers. Thanks for any insights. Tim Herren Systems Technician Puzzle ITC GmbH
