LXC won't start after storage resize

[Hashji]

Hello,

after a manually stop and storage resize of a container it isn't possible to start it again.

PCT config :

hostname: Debian
memory: 4000
ostype: debian
rootfs: local:105/vm-105-disk-0.raw,size=438345600K
swap: 2000
unprivileged: 1

Log before any change : lxc.txt

"pct mount 105" works and /etc/debian_version was empty. So I changed it with "9.12".
Unfortunetly, "lxc-start -n 105 -F -l DEBUG" display nothing and still won't start.

Log after change : lxc2.txt

Thanks a lot for your help !

hi,

did you try updating? it seems like this hasn't been updated for a while.

you can try apt update && apt full-upgrade to get the latest version of 5.x branch and see if that fixes things for you.

Thanks for your help !

Yes, It's already up to date.

how did you do the storage resize?

rootfs: local:105/vm-105-disk-0.raw,size=438345600K looks weird. how much increase did you do?

 

[Hashji]

I resize the disk on the panel : Ressources -> Resize Disk
I added 100G

 

[oguz]

can you check the actual size of the raw disk? it should be in /var/lib/vz/ somewhere (since local is the selected storage)

du -b filename

 

[Hashji]

root@nsxxx:/var/lib/vz/images/105# du -b vm-105-disk-0.raw
448865894400    vm-105-disk-0.raw

 

[oguz]

it looks like the real size of the file doesn't match with the config. maybe try editing the config manually and copy paste the size (with K at the end)

he doesn't want to start


PS:
I have data on it, but when I use "pct mount 105" some of them no longer appear. Any idea to recover them? Are they deleted?
Otherwise, no problem, I have a fairly recent backup (few missing files).
