Dragonfish RC: make root (/) RW

TrueNAS General
1

Hi there!
is there a way to make the root partition (/) rw?

I need to write some files to make Rsync properly working
(I have no problems doing that on cobia)

Yes and no. It entails being branded a hacker, so you might want to provide more detail so that we can offer an alternative.

I have a Rsync job to a Synology nas, and I have to put my syno.pw file (the one with password to the nas) on the root partition.

I’ve it also in the /root/ folder (the one of the user root) but fore some reason it not work in there (and this also on cobia)

No, that’s a bad idea. Surely you’d want it in some persistent (i.e. Backed by your main pool) location, like /mnt/poolname/home/whatever. Otherwise, with every update you’d have to reconfigure everything.

I’ve put the file in /mnt/tank/App_configs/syno.pw

chown rsync:rsync /mnt/tank/App_configs/syno.pw
chmod 600 /mnt/tank/App_configs/syno.pw

and updated the paramaters

So what do the rsync logs say?

8

I’m trying to figure out where to find them :sweat_smile:

9

Is there anything like rsync.log in /var/log/?

10

I’ve looked at messages, syslog and cron with no luck…

11

uh btw no rsync.log in there :sweat_smile:

12

Yes, run the command install-dev-tools as root and it’ll setup RW /, as well as installing various developer tools. Reminder, this means you are unsupported territory, use caution and changes won’t persist across upgrades.

If you want something persistent, use Sandboxes / Jails:
