Not sure when this started, but after several restarts following OH3 implementation I’ve had StartPersist items not update. My mapdb.persist file is configured as: Strategies { default = everyUpdate } Items { // persist all items once a day and on every change and restore them from the db …

I just installed MapDB an it seems to be working, see this DEBUG output. 2020-10-22 16:54:51.469 [DEBUG] [pdb.internal.MapDbPersistenceService] - store called for OpusPi_Cpu_SystemUptime 2020-10-22 16:54:51.476 [DEBUG] [pdb.internal.MapDbPersistenceService] - Stored 'OpusPi_Cpu_SystemUptime' with s…

This may apply too. [image] openHAB 3.0 Milestone 1 discussion News & Important Changes @4u2fast Do you use MapDB to restore values on startup? We have some discussion here and it may be the cause:

OH 3.0.0~S1979-1, newly updated this AM. I was having some issues with this after migrating to OH3 but didn’t test it thoroughly, so I cannot say when it really happened. I had mapdb installed previously and it moved over with my migration, so I had not changed any configuration up to this point. …

Thanks @Bruce_Osborne . The issue looks similar, but I have a feeling not quite the same. My log entry " Failed to save history java.nio.file.AccessDeniedException: /var/lib/openhab2 " Suggests there is a path hard coded that is a relic of OH2?

No that issue doesn’t apply here. It was commented because it has been difficult to find the real cause and at first we thought it was MapDB. You can look at [influxdb] Exception when storing integer values · Issue #8798 · openhab/openhab-addons · GitHub for details

@DaveL Have you migrated from OH 2.4 or ealier version to OH 3.0? Or are you using a new (empty) installation of OH3? I run into the same error by migration from 2.4 to 2.5.8. My only solution was to delete mapdb related files from \userdata\persistence\mapdb and start with an empty mapdb. For m…

[image] HomeAutomation: My only solution was to delete mapdb related files from \userdata\persistence\mapdb and start with an empty mapdb. Thanks, @HomeAutomation . I did try this as well, deleting all of the files in this folder and restarting OpenHAB but I continue to see the same issue. I…

So it has been over a month since this problem has surfaced. I’m now running 3.0.0 S2039 (after running M3) and in all of this time, mapdb continues to not function. I’ve uninstalled the binding, deleted it’s storage files…several times in fact. And it continues to do nothing. Is there something…

If you are seeing this problem although the binding got reinstalled and all old persisted files got deleted I’d file an issue on github. However, do you still see this message Failed to save history java.nio.file.AccessDeniedException: /var/lib/openhab2, or is made just doing nothing?

I again ran a debug, log:set DEBUG org.openhab.persistence.mapdb And NOTHING (!) shows up in the log files beyond an INFO entry: [port.EventAdminConfigurationNotifier] - Sending Event Admin notification (configuration successful) to org/ops4j/pax/logging/Configuration Which seems to indicate onl…
