Import disk to temporary location non root - similar question to "Where are VMs stored?"

[eugenevdm]

We have four disks:

local, local-lvm, raid1, raid0

I need to import a large file to raid1.

The idea is create new directory, e.g. /root/vm.import.temp, and get the job done.

Problem is /root volume is too small but there is a lot of space on the other volumes.

I can't figure out if it's possible to `cd` to the bigger volumes. The `mount` command doesn't show me where to look. `fdisk` looks weird. I'm so out of my depth.

Any tips? Output of `lsblk` and /etc/pve/storage.cfg

# cat /etc/pve/storage.cfg
dir: local
    path /var/lib/vz
    content backup,vztmpl,iso

lvmthin: local-lvm
    thinpool data
    vgname pve
    content images,rootdir

lvmthin: raid1
    thinpool raid1
    vgname raid1
    content rootdir,images
    nodes proxmox1

lvmthin: raid0
    thinpool raid0
    vgname raid0
    content rootdir,images
    nodes proxmox1

# lsblk

I need to import a large file to raid1.

What kind of file? What do you need to do with it? A disk image that should be used in a VM? If so, have a look at the qm importdisk command which might make the whole procedure easier for you.


Otherwise, you could create a manual logical Volume in either raid1 or raid0, format it and mount it to place the file there.
