Outage of gitlab.common-lisp.net
by Erik Huelsmann 17 Apr '22

17 Apr '22

Hi, common-lisp.net GitLab instance is set to maintenance mode since last night due to unexpected outage: around 19.20 CEST, phoe approached me on the common-lisp.net:matrix.org chat channel (a.k.a. #common-lisp.net:libera.chat) about the unavailability of the with-contexts project. Logging into the system, it quickly became apparent that one of the discs had filled up, causing this failure. After a bit of research, it became apparent that some 23GB (less than 10% of space on the volume) of disc space was taken by Prometheus. A tool we're not using, but which comes out of the box with GitLab. Disabling Prometheus and removing its files quickly freed up enough space for basic web requests to work again. To have some more room for various processes to operate with, I'm using a maximum of 80% fill-rate for the volumes in the VM. So, I went looking for more possibilities to clean out storage. At one point, I ended up GitLab's PostgreSQL directory, where there was a little more than a GB of storage to be won. Not a lot, but since I was cleaning anyway, it seemed like a good thing to look at. There were clearly old Pg clusters (various Pg10 and Pg11 clusters while we were running on 12). There also was a script called "delete_old_clusters.sh". It seemed better to use a script from the vendor than meddling with the database data myself, so I used it. HOWEVER: it immediately and without warning *removed the production database* (contrary to the expectation that it would remove the *old* clusters laying around)! Although this is rather unfortunate, series of events, I quickly recovered from the heart attack that followed; turned off as many services on the machine as possible and searched (a) for older database copies and (b) for dumped backups. Unfortunately, misforture never comes alone: as soon as I found the backup, I realized it's from Feburary 27th. The backup system that had been running without problems for *years* had stopped running after March 1st and none of the current maintainers noticed: since the backup procedure didn't generate an error, but was plainly not executed, there were no mails about backups failing. On top of that, it turns out that the system I have in place to report disk usage problems, wasn't delivering messages of the common-lisp.net disk overage either! I've restored the database backup from the 27th and we have the backup procedure running again. This means that anything stored in the database is back to the 27th. MRs, issues, etc. The *repositories* are fine and never were in danger! So far, I've waited to enable the service, because I've contacted the #gitlab:libera.chat channel to ask if anything can be done to assure consistency between the repositories and the database. So far, the channel has remained silent (not just to my question, but to any questions posed). I am thinking to restore access on monday night CEST, if no answer appears on the gitlab channel, or as much earlier as a usable answer will be provided. Let me close off this mail by offering my sincere apologies for failing the trust you have put in me and for any inconvenience this may have caused. Please report any inconsistencies you run into to admin at common-lisp.net so we can work on fixes. Additional controls are being worked on to prevent a similar situation in future: "ping" messages from the monitoring infrastructure and checks on the off-site backup system to check that the weekly full backup (and the daily incrementals) have been delivered. -- Bye, Erik. http://efficito.com -- Hosted accounting and ERP.
