directory is expected to be a mount point but is not mounted

[tjaroszuk]

I am new to proxmox,
Recently I have mounted a directory which is not visible after reboot.
now I got the error :
TASK ERROR: unable to activate storage 'disc_images' - directory is expected to be a mount point but is not mounted: '

the storage.cfg is following

​

could you help me to to sort it out?

 

[dcsapak]

how do you mount /mnt/pve/disc_images ?

how did you create it ?(with the gui?, if yes what settings did you make there?)

 

[tjaroszuk]

I had created it via gui only. Tt is visible in gui but not mounted


in fdisk -l hdd/partition is also visible

 

[dcsapak]

ok there should a systemd-mount service

what does

systemctl status mnt-pve-disc_images.mount

say?

 

[tjaroszuk]

it fails

Found the discrepancy in the configurations.

Proxmox try to mount /dev/disk/by-uuid/8342a29c-cd1c-4472-94b6-45fd0989b082

According to fdisk identifier is “Disk identifier: E8AC2337-E89A-4022-B656-03EBE59A5C47”



How does change it in proxmox?

I am still puzzled how it could happened – all actions had been made in GUI ( no CLI)

 

[dcsapak]

what does it say if you do:

mount /dev/disk/by-uuid/8342a29c-cd1c-4472-94b6-45fd0989b082 /mnt/pve/disk_images

?

also a

ls -lh /dev/disk/by-uuid/

can help

you can edit the service with your favorite editor e.g.
/etc/systemd/system/mnt-pve-disc_images.mount

 

[tjaroszuk]

There you are - no positive effect
moreover the fdisk and ls -lh /dev/disk/by-uuid/ different identifiers

 

[dcsapak]

oh i misspelled, try:

mount /dev/disk/by-uuid/8342a29c-cd1c-4472-94b6-45fd0989b082 /mnt/pve/disc_images

 

[tjaroszuk]

mount /dev/disk/by-uuid/8342a29c-cd1c-4472-94b6-45fd0989b082 /mnt/pve/disc_images

does not work.


I have reinstalled proxmox 5.4 manually configured

storage.cfg

and then it worked.

After reboot i need to mount it again manually.

Does Proxmox uses the standard debian mount via

/etc/fstab

or is it the other propertary way?

 

[dcsapak]

does not work.

what exactly is the error message?

or is it the other propertary way?

you can of course use fstab, but when you add it via gui there will be a systemd mount unit (like i said earlier)

 

[tjaroszuk]

I did it via gui and lost all content on the HDD

I have the same problem with an external USB Drive, which is connected to a sever and it should serve as Backup drive for both servers.

On the one, where it is attached directly I can access the Backup section on the other one I am getting the error message.

I've just encountered a similar issue, I had a USB drive (completely blank). I created it via the GUI and added it as a backup drive. It took a full backup of a VM last night and then this morning randomly "unmounted".

I think manually creating the mount in /etc/fstab using UUID (lsblk and blkid to make sure i have the correct drive and UUID) before using it in the Proxmox GUI is the way to go because I also did that with another drive and that's working fine.

I suspect this is an issue more likely to affect removable devices. What I think triggered it in my case is I had temporarily mounted a /dev/sdb and the backup drive was /dev/sdc I unmounted and removed the /dev/sdb and the backup drive has now been assigned /dev/sdb instead of /dev/sdc

Same happened to me now. USB backup drive (added to Proxmox as a backup drive via GUI) is randomly unmounted.
