HDD shows only 18.08GB of space, when the disk contains 93GB

[juan.mg]

Hi, im farly new with proxmox, recently partitioned and added those partitions as "directory" disks from the command line. I did it creating .mount files in /etc/systemd/system/, the console is showing them, but 2 out of 4 shows only 18GB avaible from the 80GB or 100GB that they have, which is exactly the same as "local" disk, and lsblk dont show them mounted (as opposed to the other 2 working fine).

I did the exact same thing with the 4 partitions, so i dont know what this is not working.

The ones not working right are HDD1 (sda1) and HDD3 (sda3), while HDD2 (sda2) and HDD4 (sda4) are working fine

Some outputs:

lsblk

Thanks for the help

In the first output you see that only 2 out of the 4 are mounted.

When creating a Directory storage on a path that is mounted from outside PVE itself, you should add the following to lines to that storage:

is_mountpoint 1
mkdir 0

Otherwise it will just use the directories you specify and doesn't know that it should wait until something is mounted there.

Thanks, so how would be the correct way to mount the partition with pvesm? I tried

pvesm add dir HDD1 -path /mnt/pve/HDD1 --is_mountpoint yes

but is throwing an error create storage failed: error with cfs lock 'file-storage_cfg': unable to activate storage 'HDD1' - directory is expected to be a mount point but is not mounted: '/mnt/pve/HDD1', the documentation is not really well explained on how to use it.

I'll keep trying and if i can do it ill post the answer here

In your lsblk output you can see that only sda2 and sda4 are actually mounted. Make sure those are mounted as well and everything should work.


I am curious, why do you even want to split up the disk in 4 partitions?

I mounted the 4 of them the same way (which is not the right way, since i copied files and modified the partitions) thats what surprises me, i dont understand why 2 are working and other 2 are not.
Another thing to have in mind is that i used mount /dev/sda1 /mnt/pve/HDD1 and it worked (in the web GUI it appeared with his 80GB), but just once, after i rebooted the machine and tried again it didnt work, and also when i wrote it on /etc/fstab it crashed the machine.

To have a better management of the things in them, and also the tutorials i saw use different disks for isos/vms, etc. Should i use everything in a single partition?

I would only use one partition. With the different partitions you complicate the setup beyond what is necessary and limit yourself as to how much space is available for things like ISOs and VMs by the partition size which cannot be changed easily later on.

Okay will do, thanks for the help
