Move logs to a Samba share?

Hello there
As the SD cards are not that good for lot of writes, I was wondering if it would be possible to propose an option to move le log files (/var/log/openhab2 or more) to a samba share ?
Today lot of boxes are providing the capability to add an external HD and make it available on the network, so it’d be very good

That would make OpenHAB and possibly your IS dependent on another system and the network between them. That decreases simplicity and likely reliability.

As a UNIX expert I would not move the logs. The OS by design assumes the log directory is always accessible and writable.

Use ZRAM. It keeps active logs in RAM to mitigate SD wearout and rotates them to SD only once (or anywhere you tell it to), see last parameter in /etc/ztab.
You can mount some long term storage dir off a NAS but as @Bruce_Osborne currectly notes don’t move /var/log there, it creates dependencies you don’t want to have.

ok, I was going to try that, bu the setup doesn’t work from my raspi 4 :

$ apt-get install -y -q --no-install-recommends make libattr1-dev

Just for completeness:
you may have a look to the manual of the syslog daemon of your system.
In case it is rsyslogd e.g.:
It describes which logs at which level will be stored in which file - filelocation.
Via a configuration file in /etc/ directory this is configurable.

It works with a fresh install so I’d guess you messed up your repo or apt config or cache.
