[SOLVED] pct create --rootfs parameter syntax

[joshy]

Hi Forum,

I am trying to learn how to create containers via the PCT command. However, Ive hit a issue with not understanding the syntax of the --rootfs parameter.

What is the syntax of the the rootfs? From PCT man page

--rootfs [volume=]<volume> [,acl=<1|0>] [,mountoptions=<opt[;opt...]>] [,quota=<1|0>] [,replicate=<1|0>] [,ro=<1|0>] [,shared=<1|0>] [,size=<DiskSize>]

Since volume is required, how can I find out what are valid values on my environment for volume? I have local and local-lvm but neither are accepted.

Now I manage to find example that creates a 4G disk on local-lvm
pct create 401 local:vztmpl/debian-11-standard_11.3-1_amd64.tar.zst --rootfs local-lvm:4

But how does local-lvm:4 map back to the man page options? Using --rootfs man page syntax for the pct create command what is the equivalent syntax?

Is there a log file where I can see the command that the UI generates using the command line syntax?

hi,

But how does local-lvm:4 map back to the man page options? Using --rootfs man page syntax for the pct create command what is the equivalent syntax?

in the manpage it's detailed under --mp[n]:

Use volume as container mount point. Use the special syntax STORAGE_ID:SIZE_IN_GiB to allocate a new volume.

this works the same way for rootfs.

Is there a log file where I can see the command that the UI generates using the command line syntax?

the UI does not always generate a command, since the parameters go to the API (in fact pct etc. tools also utilize the API calls)

If you use local to storge the CT image, you need to enable this feature first
In /etc/pve/local/lxc/xxx.conf can see the parameter looklike “rootfs: local:100/vm-100-disk-0.raw,size=8G”

and you can use the search
