Since installing system updates around two weeks ago (~April 10), the Performance Statistics collected since then are not persistent after rebooting. Statistics before that date are still present.
When checked immediately after restarting, the statistics show "last update: April 10" and after refreshing there is no data from around that date to the present.
I also tried to check previous boot logs with: sudo journalctl -ef -b -1 which fails with: "Specifying boot ID or boot offset has no effect, no persistent journal was found." In the OMV GUI, the boot log has only the last boot, but the Syslog goes back beyond the current boot.
What has happened?
Possibly related to this reported issue with FlashMemory plugin: FlasMemory (Folder2ram) plugin issue
