LXC ls not showing proper names

hypeit · February 26, 2023, 8:50am

Hi all,

Today I found a very funny bug in lxd.
Very simple case, I am using a script to provision instances:

#!/bin/bash

[[ -n "$(lxc ls | grep maas-ha)" ]] && lxc stop maas-ha-1 maas-ha-2 maas-ha-3 maas-ha-db-1 maas-ha-db-2 maas-proxy-1 maas-vault-1 && lxc delete maas-ha-1 maas-ha-2 maas-ha-3 maas-ha-db-1 maas-ha-db-2 maas-proxy-1 maas-vault-1

lxc launch images:ubuntu/jammy/cloud  maas-ha-1 -p container-vlan10-maas --target infra1 -c user.network-config="$(cat /home/mother/cloud-init-scripts/network-config-infra-container-maas.yaml | sed -e 's/IP_ADDR_10/10.10.10.101/g;s/IP_GATEWAY/10.10.10.1/g;s/IP_ADDR_99/10.10.99.101/g')"
lxc launch images:ubuntu/jammy/cloud  maas-ha-2 -p container-vlan10-maas --target infra2 -c user.network-config="$(cat /home/mother/cloud-init-scripts/network-config-infra-container-maas.yaml | sed -e 's/IP_ADDR_10/10.10.10.102/g;s/IP_GATEWAY/10.10.10.1/g;s/IP_ADDR_99/10.10.99.102/g')"
lxc launch images:ubuntu/jammy/cloud  maas-ha-3 -p container-vlan10-maas --target infra3 -c user.network-config="$(cat /home/mother/cloud-init-scripts/network-config-infra-container-maas.yaml | sed -e 's/IP_ADDR_10/10.10.10.103/g;s/IP_GATEWAY/10.10.10.1/g;s/IP_ADDR_99/10.10.99.103/g')"
sleep 5
lxc launch images:ubuntu/jammy/cloud  maas-ha-db-1 -p container-vlan10 --target infra1 -c user.network-config="$(cat /home/mother/cloud-init-scripts/network-config-infra-container.yaml | sed -e 's/IP_ADDR_10/10.10.10.105/g;s/IP_GATEWAY/10.10.10.1/g')"
lxc launch images:ubuntu/jammy/cloud  maas-ha-db-2 -p container-vlan10 --target infra2 -c user.network-config="$(cat /home/mother/cloud-init-scripts/network-config-infra-container.yaml | sed -e 's/IP_ADDR_10/10.10.10.106/g;s/IP_GATEWAY/10.10.10.1/g')" 
sleep 5
lxc launch images:ubuntu/jammy/cloud  maas-proxy-1 -p container-vlan10 --target infra1 -c user.network-config="$(cat /home/mother/cloud-init-scripts/network-config-infra-container.yaml | sed -e 's/IP_ADDR_10/10.10.10.104/g;s/IP_GATEWAY/10.10.10.1/g')"
lxc launch images:ubuntu/jammy/cloud  maas-vault-1 -p container-vlan10 --target infra2 -c user.network-config="$(cat /home/mother/cloud-init-scripts/network-config-infra-container.yaml | sed -e 's/IP_ADDR_10/10.10.10.107/g;s/IP_GATEWAY/10.10.10.1/g')"

Script executes correctly and at the end I want to check the machines and seeing:

mother@infra3:~$ lxc ls --project maas

As far as I know, April’s fool is in one month

The instances exist and are reachable but it’s kind of irritating to not to be able to see them

Thanks

Initially I thought that it may be some kind of overlapping of ip, since including 4 in command lxc ls -c 4n causes the output to look this way, but that is not possible, is it?

but why does it behave like this?
The only possble explanation may be me having run lxc network unset lxdfan0 ipv6.address ; lxc network unset lxdfan0 ipv6.nat
But since ipv6 cannot be handled with in fan mode I doubt it had any effect…

tomp · February 26, 2023, 4:48pm

Do the missing instances have ipv4 addresses?

I’m trying to understand what’s different about the missing instances.

tomp · February 26, 2023, 4:49pm

Are the missing instances lacking an eth0 by any chance?

hypeit · February 26, 2023, 4:55pm

No, neither of those, all instances are reachable

tomp · February 26, 2023, 6:21pm

Any ideas what’s different about them? Or if you run the command repeatedly do they show? Also have you tried adding a filter for the name of one of the missing instances (while still keeping the 4 option) and see if it appears?

tomp · February 26, 2023, 6:24pm

On an unrelated (I think) issue I actually significantly reworked lxc list the other day (not in the snap yet).

So there’s a decent chance this is already fixed.

But I would like to see if we can figure out what is wrong to double check.

hypeit · February 26, 2023, 7:17pm

To be honest there is absolutely nothing different about them, they all use the same profile. I tried the filter(even from remote) but no avail

Cam you show lxc config show <instance> --expanded for one of the appearing and one of the equivalent missing ones please?

Yes, that was the first thing I did, but maybe we can use your expertise here

I also noticed a very strange thing, namely some new problems with maas installation on these containers, as the name suggests they are used for maas installation.
The problem with listing tends to coincide with the maas initialisation error

ERROR: Failed to retrieve storage information: Failed to find “/dev/disk/by-path/pci-0000:00:1f.2-ata-1”: lstat /dev/sr0: no such file or directory

Can it be somehow related?

tomp · February 27, 2023, 8:11pm

Ah yes potentially.

I remember from my reworking of lxc list that in the previous version it skipped entries if there was a problem loading state info.

I’ll look into whether that could be the issue and whether it still exists in its current form.

@tomp thank you very much, I jest realized I assigned wrong pool to my containers, but unfortunately it did not solve anything All continers use remote pool now but lxc ls still shows no valid output.

By the way I just found that the local zfs pool still has some images after removing the provious containers, is it possible to somehow prune zfs pool?

Small update

Yesterday I faced a problem with microceph(ceph rbd wan not able to unmount the instances located on 2 of 3 cluster members) and due to lack of time I decided to simply restart those 2 cluster members.

It seems the restart has resolved the issue for now but it is quite worrying to be honest…

@tomp do you have any suspects of this? Could it be that one member was somehow causing the DB not to refresh?

1.3.2023 UPDATE

No I am sure that one of cluster nodes is causing the problem.

The ls works fine until it comes to the point of infra2.

@stgraber, @tomp do you have any idea how to troubleshoot the node?

Hi,

Today I observed another thing, namely, the 3 containers that have maas installed have tendency to freeze completely, what I mean by that is the fact that it is not possible neither to lxc shell into them or exec anything, the stop freezes. The only thing that works is to force stop and then start:
An example would be:

Ubuntu 22.04.2 LTS maas-ha-2 console

The difference between these 3 containers that are freezeing and others is lack of:

 raw.lxc: |
    lxc.apparmor.profile=unconfined
    lxc.mount.auto=proc:rw sys:rw
    lxc.cap.drop=
  security.nesting: "true"
  security.privileged: "true"

The reason for not including it was not being able to install maas (the stupid device error during maas initialisation).

Can it have any implication?

tomp · March 2, 2023, 4:19pm

You shouldn’t really ever use security.nesting and security.privileged together as that introduces a big security issue.

https://github.com/lxc/lxd/issues/7085#issuecomment-604402829

tomp · March 2, 2023, 4:24pm

Also that doesn’t do what I think you think it does, in that it does remove not all AppArmor profiles from being applied.

See Problem with disable apparmor for single container - #4 by stgraber
