Hello,
I am pretty new to OMV (had QNAP for years) and I am still in 'experiencing and testing' mode.
Today I ran into a full rootfs after starting rsync to backup some data on an USB external HDD which is connected all the time to the NAS and mounted to /srv/dev-disk-by-label-backup/.
The command executed was: /usr/bin/rsync -av /srv/dev.../media/ /srv/dev-disk-by-label/media/
I found out that although the external USB drive was never removed from the NAS it seems to be unmounted or in some sort of an unknown state probably due to automatic spindown. It does not show up in the WebIF Drives section and I have to click on the 'Search' button to make it reappear.
My questions are: How can I prevent such a behaviour (accidently backing up data to the rootfs because of a 'sleeping' device) and how could that even happen? Shouldn't the drive reappear automatically if a process is trying to accessing it?
Thank you in advance
Regards
Michael
