Hard drive at proxmox

[aluix12]

Hello good morning everyone, hoping you are well.

I have a problem and I hope you can help me. I have installed a proxmox v6 on my dedicated server with 6TB of disk, the problem is that it only recognizes 2tb. I have added the remaining 4 by:

Datacenter / Storage / Add Attached image:



But when added they appear to me that they are full.





The dedicated server is new and I have just installed proxmox, how can I free up the space of my two disks that are full for proxmox? thank you

You added them as LVM. Did you create LVM or was it already present?

If you could show the contents of /etc/pve/storage.conf and the output of the following commands, we might be able to figure out what is going on. It's best to put it in [CODE] tags so it will not lose the spacing.

• lsblk
• pvs
• vgs
• lvs

/etc/pve/storage.conf it is empty

My bad, it's /etc/pve/storage.cfg

Well, from what I can see you have an MD RAID in RAID1.

  └─md4          9:4    0    1.8T  0 raid1

Which means you mirror it across three disks. With this, it is absolutely normal, that you only see the 2TB out of 6.

By the way, we do not officially support MD RAIDs and recommend to use ZFS if a software RAID is to be used. But be aware that RAIDZs can be tricky if you run VMs on them. See https://forum.proxmox.com/threads/zfs-counts-double-the-space.71536/#post-320919

You current setup is redundant, which means you can tolerate a disk failure. You want to break that redundancy and access each disk individually? You need to reinstall everything.
