[Freeipa-users] Apparently transient error cl5DBData2Entry - Invalid data version

Hi We have 3 IPA servers which we are in the process of updating from RHEL 7.7 to RHEL 7.8. Servers X, Z are at: ipa-server-4.6.6-11.el7.x86_64 (RHEL 7.8) Server W is at: ipa-server-4.6.5-11.el7_7.3.x86_64 (RHEL 7.7) Server X was updated some time ago, and server Z was updated last Thursday. I was doing some checks of the log files before our planned update of server W to RHEL 7.8 tomorrow and found the following in /var/log/dirsrv/slapd-REALM/errors: [26/Apr/2020:22:00:21.704887592 +0100] - INFO - dblayer_copy_directory - Backing up file 119 (/var/lib/dirsrv/slapd-REALM/bak/REALM/ipaca/vlv#cacompleterenewalpkitomcatindex.db) [26/Apr/2020:22:00:23.627421118 +0100] - ERR - NSMMReplicationPlugin - changelog program - cl5DBData2Entry - Invalid data version [26/Apr/2020:22:00:24.760704543 +0100] - INFO - dblayer_copyfile - Copying /var/lib/dirsrv/slapd-REALM/db/ipaca/vlv#cacompleterenewalpkitomcatindex.db to /var/lib/dirsrv/slapd-REALM/bak/REALM/ipaca/vlv#cacompleterenewalpkitomcatindex.db [26/Apr/2020:22:00:24.776815976 +0100] - ERR - NSMMReplicationPlugin - changelog program - cl5DBData2Entry - Invalid data version The errors were generated during our cronjob that runs this each night: /sbin/ipa-backup --data --online The errors don't seem to have been present the last two nights. Would I be right to assume that this is just some transient inconsistency caused by doing the online backup or should I be more worried even though the error hasn't occurred since? Thanks for any insights on this. Roderick Johnstone
