[SOLVED] Debian 10 container disks disappear

[tayra]

Hello!
I use proxmox 6.2
Debian 10 containers not loading with error:

run_buffer: 323 Script exited with status 32
lxc_init: 797 Failed to run lxc.hook.pre-start for container "219"
__lxc_start: 1896 Failed to initialize container "219"
TASK ERROR: startup for container '219' failed

The disk with the container number disappears in the /dev/Data directory. The LVM section is there, and it hasn't gone anywhere. How to return the container disk to the directory /dev/Data? Why does it disappear from it?

what is the /dev/Data directory?

could you post cat /etc/pve/storage.cfg output as well?

>what is the /dev/Data directory?
It's default proxmox directory, I do not know, what is this

this is /etc/pve/storage.cfg:

lvmthin: VMdata
        thinpool VMData
        vgname vd-data
        content rootdir,images

nfs: NAS4
        export /mnt/btrfs/VMBackup
        path /mnt/pve/NAS4
        server 192.168.2.53
        content backup,images,vztmpl,rootdir,iso
        maxfiles 4
        options vers=3

lvmthin: VMdata2
        thinpool VMdata
        vgname Data
        content images,rootdir
mthin: VMdata dir: local thinpool VMData path /var/lib/vz vgname vd-data
        content vztmpl,snippets,iso,rootdir,images content rootdir,images
        maxfiles 0

it's definitely not default, you can see it in your config

but the formatting looks off. does it really say mthin in your config? please paste it correctly here

 

[tayra]

Indeed, this is my fault. Damaged config when copying. Thanks!

 

[oguz]

did you fix your config? was the problem solved?

 

[tayra]

Yes, the problem is solved. Thank you!

 

[oguz]

great, please mark the thread as [SOLVED] by editing the thread prefix so others who do the same can know

 

[tayra]

did not immediately find where to change the status as solved
