@Zabe I saw that you handled T329577 a few years ago and I'm wondering if you can help me bring deployment-db15 online to take over for deployment-db14 (xref
T428910#12010836).

I have a 120Gib db15 volume mounted on /srv.

I used the following command to get past the puppet problem:

sudo -u mysql /opt/wmf-mariadb1011/scripts/mariadb-install-db \
    --basedir=/opt/wmf-mariadb1011 \
    --datadir=/srv/sqldata
root@deployment-db11:~# time /opt/wmf-mariadb106/bin/mariadb-dump --all-databases --single-transaction --gtid --triggers | gzip > /srv/db11-seed.sql.gz

https://gerrit.wikimedia.org/r/1300914

I copied /srv/db11-seed.sql.gz from deployment-db11 to deployment-db15 and I'm running

zcat /srv/db11-seed.sql.gz | sudo mysql

Sure. Please tell me if I can do something. :)

[operations/mediawiki-config@master] beta: Replace deployment-db14 with deployment-db15

https://gerrit.wikimedia.org/r/1302202

@Zabe I saw that you handled T329577 a few years ago and I'm wondering if you can help me bring deployment-db15 online to take over for deployment-db14 (xref
T428910#12010836).

Sure. Please tell me if I can do something. :)

Thanks Zabe. I was initially worried about getting stuck but I was able to eventually figure everything out, but thanks for being available!
