Storage management in Immich?

[perelin]

To understand the issue: when I restore a backup there might possibly be

a) new photos in the external store that are not in the restored db because they were added to Immich in inbetween backup and restore time

and/or

b) photos missing in the external store that are still in the restored db because they have been deleted from Immich inbetween backup and restore time

Both sound like states that Immich should address at some point in their ongoing development. Either re-index the storage path or clean db of file entries no longer available. But I have not checked if they have discussions ongoing about such features.

I generally would opt for letting users shoot themselves in the foot, given enough red, bold disclaimers

[jdaviescoates]

Yeah, I mean, I don't see how Immich is really any different to Calibre Web, Navidrome, Jellyfin etc etc that all allow for custom paths for the location of their libraries and just routinely reindex that location occasionally

[perelin]

@nebulon are you open to explore this further at some point in the future? Immich seems pretty pointless (to me) without the option to plug-in your own storage.

[jdaviescoates]

@perelin I think best bet is to relay that upstream directly to Immich

[perelin]

@jdaviescoates Hard to make a case there when all of their installation methods are somewhat around Docker Compose or similar systems.

From their Docker Compose file I can see that they just mount an external folder to their internal, hardwired upload location -> https://github.com/immich-app/immich/releases/download/v1.132.3/docker-compose.yml

I dont know where I can lookup the Cloudron/Immich integration, but I guess the mounting could happen when the Dockerfile gets run. But of course at first there is no mounted file system available

[perelin]

So, after some exchanges in the Immich Discord I managed to switch my existing Immich Photo Library to an external volume on a Hetzner Storage Box by copying the files (./upload/*) and setting the IMMICH_MEDIA_LOCATION to a mounted storage volume in /media/
Immich started up again and displayed all my photos.
BUT: it seems I cant upload new photos Not sure why, the /media/ mounted volume (Hetzner Storage Box) seems to have full permissions. Here is the Immich log when trying to upload a file:

Any ideas how to debug this?

[nebulon]

Immich runs as the cloudron user within the container. If you open a webterminal into the app, can you check if that user has write permissions to the /media/... volume?

[perelin]

Yes, tried that - basic permissions look good. It seem to be an issue with Immich trying to use utime to change timestamps on the mounted share which seem to be an issue somehow for the cloudron user. Some testing on my box shows:

Creating a testfile (touch .test) on the mounted share and then trying to change the timestamp

• works for root (-> touch -t 202501010000 .test)
• does not work for cloudron (-> sudo -u cloudron touch -t 202501010000 .test)

Not sure how to continue.

[nebulon]

For a start, how did you mount the storage box? both SSHFS and CIFS are quite particular about users and permissions. One reason why we don't support moving the main app directory onto such mount points...

[perelin]

I mounted it with the Cloudron build in mount option in the UI. Are there other options? I guess editing fstab by hand will be overwritten at some point

Here is the output of the mountcommand from the console.

root@81deeb68-0628-45ff-bf4c-0e9e294e7935:/media/FSN1-BX1401# mount | grep FSN1-BX1401

[nebulon]

right, so the issue is, CIFS with hetzner only knows one uid which is set there in the mount option. This means there are no real user IDs....does it work if you give all users? Although it is still unclear why you can write but not change mtime attribute via touch as cloudron user, if I understand correctly.

I guess that needs more investigation on how to maybe workaround that...

[perelin]

@nebulon said in Storage management in Immich?:

does it work if you give all users?

Not sure what you mean here. Mounting the share with other options? I had the impression I can not do that by myself since its managed by Cloudron.

Would love to make this work. If you tell me what to try Im happy put some time in

[nebulon]

Ah sorry, that was unclear. What I meant was, if you chmod a+rw -R the folder structure? This should give all users read/write access. Maybe that works around the single user CIFS permissions.

[perelin]

Ah, got it. Tried, didnt do anything. But the whole mounted share already had like 777 permissions throughout:

drwxrwxrwx 2 808 808 0 May 21 08:56 immich/

[nebulon]

oh right well you will hit other side-effects then with apps if the filesystem is not actually support those features. This is one of the reasons, we only allow to move the app itself onto very specific filesystems like xfs and ext4. Not sure what can be done if CIFS with hetzner does not allow this. Or maybe you can investigate if you setup the mountpoint manually on the system with other mount options?

[perelin]

Yup, I guess I will experiment a bit with the mount options available. Will report back here if I find something that works, thx!
