Hello,
My configuration is as follows: I am in ZimaOS+, v1.6.1
I have six disks in RAID5, one 22TB single, two 4TB singles.
I disabled the two 4TB singles to create a single volume of 8TB in RAID0 Result:
I then decided to put the two 4TB volumes back into singles… Same message: Storage limit exceeded
If someone has a solution…
Thanks
If you’re not on ZimaOS+, this isn’t really an error, it’s the storage cap kicking in.
With that many drives (RAID5 + 22TB + extras), you’ve gone over the free limit, so Zima just blocks any further changes, even reverting back.
Nothing broken, just the license limit.
You’ll either need to reduce active storage or move to ZimaOS+
I’m already in ZimaOS+
Ahh ok, if you’re already on ZimaOS+, then yeah this isn’t the license limit.
This looks more like the system still “holding onto” the old RAID allocation after you switched things back. It can leave the storage accounting in a weird state, so it still thinks you’re over the limit.
You didn’t do anything wrong, it’s likely just not recalculating properly after the RAID change.
At this point I’d keep it simple:
Seen a few odd edge cases like this around RAID changes
I have restarted several times. :-/
If I try to put the two disks back as single volume, as before, I have the same error message “Storage limit exceeded”.
It seems that the system keeps in memory the old connections or samba sharing for volumes or usb disk that no longer exist.
In the FILES/STORAGE/ browser I have 20 volumes in memory?? 13 are no longer present…
Yeah this explains it, those extra _1, _2 folders are leftover mount points from old disk/RAID configs.
Zima is still counting them as active storage, even though they’re not real mounts anymore, which is why you keep hitting “storage limit exceeded”.
Reboot won’t fix it because it’s not just memory, it’s stale mount + metadata.
Before touching anything, best to confirm what’s real vs leftover. You can safely run these (read-only):
lsblk -o NAME,SIZE,FSTYPE,MOUNTPOINT
df -h
mount | grep /media
What you’re looking for:
/media or in the Files appIf you can, share those outputs, the key is to identify which paths are actual mounts vs just leftover directories before cleaning anything up.
This looks like a 1.6.x storage edge case, so once confirmed it’s safe, we can guide the cleanup properly
Hello 
Now that I know the volumes that should no longer be present, is there a particular command to execute to delete the phantom directory.
Maybe a system update is in preparation?
Many thanks
Yeah, I would avoid manually deleting anything for now until IceWhale confirms the proper cleanup method, especially with the 1.6.x storage changes.
At the moment we really need to see the results from the commands posted earlier first, so we can confirm which entries are real mounted volumes and which ones are just leftover “ghost” folders.
A few of us have started seeing similar behaviour lately after RAID/layout changes, so this does look more like a storage metadata/mount cleanup issue than actual disk corruption.
Hello
Here is the result

Thanks for posting the outputs this is actually very helpful.
Your real local storage looks clean:
/media/Zima-SERVEUR/media/22To-SERVEURThose are properly mounted and consistent across lsblk, df -h, and mount.
What does stand out though is the very large number of CIFS/SMB mounts under /media/... from multiple NAS devices.
So at this point, I’m starting to suspect the Files app/storage service may be counting old network mounts and stale metadata together, which could explain why the UI thinks there are far more “volumes” than actually exist.
The good news is:
I would still avoid manually deleting folders for now until IceWhale confirms the correct cleanup method, especially with the 1.6.x storage changes.
Honestly this is looking more and more like a backend metadata issue rather than an actual storage problem
