Mapdb: no restore at startup for item status

Add-ons Persistence Services

you mean openhab-cli restore ?
OH has to be stopped to import.
Eventually (if it still does not work) stop ZRAM, too, and start again after

this worked, thanks again!

i’ve ordered a card reader and a “double-sized” sd card. i presume the setup in openhabian-config is self-explanatory? (except defining backupdrive)

well that I don’t know so just try and tell me what you think we would need to change about docs

argh. just wanted to move influxdb to zram:

[15:05:36] root@ohab2:/home/openhabian# service zram-config stop
[15:07:38] root@ohab2:/home/openhabian# nano /etc/ztab
[15:12:16] root@ohab2:/home/openhabian# zramctl
NAME       ALGORITHM DISKSIZE  DATA  COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram2 lzo-rle       500M 17.5M 402.2K  844K       4
/dev/zram1 lzo-rle       500M 30.1M   1.6M    2M       4

shouldn’t zramctl give an “empty” output?

Only if it manages to unmount everything to access the zram’ed dirs which it usually doesn’t (just to many dependencies).
Adding dirs to ztab should work nonetheless.

seems to work, yes. after reboot i had the 4 entries (as configured):

[15:27:43] openhabian@ohab2:~$ zramctl
NAME       ALGORITHM DISKSIZE  DATA  COMPR TOTAL STREAMS MOUNTPOINT
/dev/zram3 lzo-rle       500M 48.6M  51.6K  320K       4 /opt/zram/zram3
/dev/zram2 lzo-rle       500M 17.5M 285.4K  728K       4 /opt/zram/zram2
/dev/zram1 lzo-rle       500M 30.3M   1.5M    2M       4 /opt/zram/zram1
/dev/zram0 lzo-rle       600M    4K    87B   12K       4 [SWAP]

before reboot (but with started zram-config) i had these 4 entries PLUS the 2 entries from above.
