I have
No such file or directory - Could not create shmounts temporary dir
in lxc.log for container
Hi!
I cannot reproduce on Ubuntu 20.04 and LXD 3.23.
It has been reported at https://github.com/lxc/lxc/issues/2869 Can you check whether a restart of the container is able to show /mnt/tmp
?
According to the code, LXD tries to create a temporary file in the mounted point, and fails if it is read-only. My cursory look into the code does not show why there should be a temporary file in there.
For testing purposes, can you
sudo chmod 777 /mnt/tmp/
You might be able to bypass this issue if you add more parameters to the disk device, per https://linuxcontainers.org/lxd/docs/master/instances#type-disk
I use Ubuntu 18.04 and LXD 3.23
container is unprivileged
some idmap config for container
volatile.idmap.base: “0”
volatile.idmap.current: ‘[{“Isuid”:true,“Isgid”:true,“Hostid”:1000000,“Nsid”:0,“Maprange”:1000000000}]’
volatile.idmap.next: ‘[{“Isuid”:true,“Isgid”:true,“Hostid”:1000000,“Nsid”:0,“Maprange”:1000000000}]’
volatile.last_state.idmap: ‘[{“Isuid”:true,“Isgid”:true,“Hostid”:1000000,“Nsid”:0,“Maprange”:1000000000}]’
I used chmod 777
nothing changed
