bind mouted entries under /srv are mounted ro instead of rw #1355

[##]Issue information: Mounted directories unter /srv ( ) are mounted read only; not read-write after a reboot: mount |grep /srv /dev/sda7 on /srv/openhab-userdata type ext4 (ro,relatime,errors=remount-ro) /dev/sda7 on /srv/openhab-addons type ext4 (ro,relatime,errors=remount-ro) /dev/sda7 on /srv/openhab-conf type ext4 (ro,relatime,errors=remount-ro) /dev/sda7 on /srv/openhab-sys type ext4 (ro,relatime,errors=remount-ro)

They are initially mounted rw but remounted ro ( see attached logging from systemctl with debug information ).

Also running openhabian-config menu 13 immediately mounts them rw. After a reboot they are ro again.

Changing the mount template from Before=smbd.service After=zram-config.service to Before=smbd.service After=network.target

fixes this and the directories are mounted rw ( see attached logging from systemctl with debug information ).

Debug information:

see attached files srv-remounted-ro-journalctl.txt shows that the directories are mounted rw first and in later stages of systemd they are remounted ro. srv-mounted-rw-journalctl.txt shows that the directories are mounted rw.

systemd startup order is coincidential so if this worked you're lucky. Adding network.target is fine but removing zram-config.service is not. Try to add both as After= and let me know if that works

Based on your suggestion I tested After=network.target zram-config.service and I can confirm that the directories are mounted rw after a reboot.

mstormi commented 3 years ago

thanks. Have a couple of reboots at different times if you have a chance to make sure this isn't just coincidence

mstormi commented 3 years ago

I added network.target to future install pls test nonetheless @ecdye fyi

After my first reboot, I still could not write to openhab2-conf, after the second reboot it worked. I'll report on how stable this solution is.

Anyway, I noticed that on my system openhab2-logs directory is now empty.

I added network.target to future install pls test nonetheless I did 20 reboots and the folders always were mounted rw.

Ok so with #1367 merged I'll consider this to be fixed. Reopen if you encounter again
