How can I update the maas-test-db snap to 3.3/beta? When I try
snap refresh --channel=3.3/beta maas-test-db

it says “error: snap “maas-test-db” is not available on 3.3/beta”

[billwear]

@kevin-reeuwijk, have you tried a snap info maas-test-db ?

when i do this, i get this list:

I get the same list, and 3.3/beta is in there, with a PostgreSQL 14 version. But it won’t let me install it.

[billwear]

can you run snap info maas-test-db and post the output?

[kevin-reeuwijk]

I thought maybe it was blocked because the OS was Ubuntu 20.04 LTS and not 22.04 LTS. So I upgraded the OS to 22.04 LTS and tried again after, but got the same error.

[billwear]

yeah, something isn’t working as i expect it to; let me ask the team.

[billwear]

@kevin-reeuwijk, the snap description seems to indicate that this is not a upgradeable snap. you have to remove the old one and install a new one.

[kevin-reeuwijk]

I see. I don’t know how to migrate the data though, so I guess without an upgrade I’m stuck on v12 until I can rebuild the server. I’ll build it with a regular PostgresDB install next time.

[billwear]

@kevin-reeuwijk, if you think the maas-test-db needs to be migrate-able, you should add a feature request. i think the designers of the test mode didn’t expect people to migrate their test DB at all. maybe that’s a wrong assumption?

[kevin-reeuwijk]

It’s fair for the maas-test-db not to be upgradeable, but it does seem likely that people would want to migrate their DB from the maas-test-db snap to a regular PostgresDB. Is there a procedure for that documented anywhere?

[billwear]

@kevin-reeuwijk, there might be something in here (Tips and Tricks). some of it looks badly written. lemme know if you don’t find anything worth trying.

[kevin-reeuwijk]

Thanks, while somewhat outdated the information helped me to move the data from the old snap to the new one, like so:

snap stop maas
pg_dump -U maas -h /var/snap/maas-test-db/common/postgres/sockets -d maasdb -F t -f maasdb-dump.tar
snap stop maas-test-db
snap remove maas-test-db
snap install --channel=3.3/beta maas-test-db
snap start maas-test-db
/snap/maas-test-db/current/usr/bin/dropdb -U postgres -h /var/snap/maas-test-db/common/postgres/sockets maasdb
/snap/maas-test-db/current/usr/bin/createdb -U postgres -h /var/snap/maas-test-db/common/postgres/sockets maasdb -O maas
/snap/maas-test-db/current/usr/bin/pg_restore -U maas -h /var/snap/maas-test-db/common/postgres/sockets -d maasdb ./maasdb-dump.tar
snap start maas

[billwear]

@kevin-reeuwijk, can you point out what was outdated? i’d like to fix it. tia.

[kevin-reeuwijk]

Ok, here’s what I found:

• /snap/maas/current/helpers/migrate-vd no longer exists, so the entire “Migrating an existing snap installation” section doesn’t work.
• The “Manually exporting the MAAS database” section was most helpful to me, but it’s not written for the maas-test-db snap, which required me to adjust some things:
  • For the maas-test-db snap, the Postgres socket is located at /var/snap/maas-test-db/common/postgres/sockets instead of /var/snap/maas/common/postgres/sockets
  • The binaries for Postgres are not in the path and need to be run from /snap/maas-test-db/current/usr/bin
  • You don’t need to run the Postgres command as the postgres user when using the maas-test-db snap
  • You need to manually delete & recreate an empty maasdb after installing the Postgres v14 maas-test-db snap, so that the DB can be restored over it.

[billwear]

thanks! nice.

[billwear]

@kevin-reeuwijk, i ran out of time updating the doc (all-company meeting coming up for a week). if you want to edit the tips and tricks document, and flesh out the instructions, feel free, or i’ll finish it up in a couple of weeks. tia!

hi, unfortunately I fails with this error:

[billwear]

it looks like postgres isn’t properly installed, but i could be wrong?
