Invalid configuration key: unknown key" key=storage.lvm_{fstype,mount_options,thinpool_name,volume_size}

simondeziel commented 2 years ago

Since LXD snap's was upgraded:

$ snap list --all lxd
Name  Version        Rev    Tracking    Publisher   Notes
lxd   5.0.0-c5bcb80  22826  5.0/stable  canonical✓  disabled
lxd   5.0.0-e478009  22894  5.0/stable  canonical✓  -

I'm seeing the following warnings repeated over and over:

Could be left over in the local server DB, e.g. lxd sql local 'select * from config'

simondeziel commented 2 years ago

| id |          key           |      value      |

+----+------------------------+-----------------+

tomponline commented 2 years ago

Is this a standalone node?

lxd sql global 'select * from config'

simondeziel commented 2 years ago

Yes it is standalone:

# lxd sql global 'select * from config'
+----+-----------------------------+-------------+
| id |             key             |    value    |
+----+-----------------------------+-------------+
| 2  | storage.lvm_mount_options   | discard     |
| 3  | storage.lvm_thinpool_name   | LXDThinPool |
| 4  | storage.lvm_volume_size     | 10GiB       |
| 5  | storage.lvm_fstype          | ext4        |
| 6  | images.auto_update_interval | 0           |
+----+-----------------------------+-------------+

As far as I remember, I never put those configs except for the images.auto_update_interval one. Please note that this machine was initially using the Bionic deb IIRC and was migrated at some point.

tomponline commented 2 years ago

Ah OK well looks like they got left behind somehow during a migration patch and are no longer catered for in LXD 5.0.

You should be able to delete them individually using this approach:

sudo lxd sql global "delete from config where key = 'storage.lvm_mount_options'"

simondeziel commented 2 years ago

Thanks for the instructions on how to fix it but maybe LXD could be a bit less aggressive when complaining about it. I have ~2700 such warnings per hour.

tomponline commented 2 years ago

It'll likely be warning every time it tries to access the global config.
