Can the FlashMemory plugin add custom folders?

Hello everyone,

Although the FlashMemory plugin indicates that no configuration is required, is it possible to manually add a folder so that it can also be read from and written to the memory?

The main reason is that I have placed the Docker data directory on the SSD, and Jellyfin stores the transcoding directory at /data/jellyfin/cache/transcodes. Whenever a video needs to be transcoded, it places the transcoding chunks in this directory, and the directory is cleared after stopping playback. I'm concerned that this may cause unnecessary wear and tear on the SSD.

Thank you for any help.

Yep. Just set the OMV_FM_EXTRA_DIRS environment variable. directories should be comma separated.

This is how you set an omv environment variable:

sudo omv-env set OMV_FM_EXTRA_DIRS "/path/to/dir1,/path/to/dir1"

Then follow the rest of the directions in the omv environment variable wiki - https://docs.openmediavault.or…table/various/advset.html

Thank you for your help.

root@nas:~# sudo omv-env set OMV_FM_EXTRA_DIRS "/docker/data/jellyfin/cache/transcodes"

root@nas:~# sudo omv-env get OMV_FM_EXTRA_DIRS
OMV_FM_EXTRA_DIRS=/docker/data/jellyfin/cache/transcodes

root@nas:~# sudo monit restart omv-engined
root@nas:~# sudo omv-salt stage run prepare
root@nas:~# sudo omv-salt stage run deploy

I ran the above command in ssh and restarted the system. I can indeed see that the memory usage keeps increasing during Jellyfin transcoding, and it decreases when I stop the video.

A stupid question: there are still transcoding fragments in the transcodes directory. Are they mapped from memory to this folder?

No. The folders created by folder2ram are using tmpfs. The program doesn't even know they are in ram. It is just a regular file.

If that's the case, then I can rest assured. Thank you again for your help.
