I woke up this morning to a text from my ISP, “There is an outage in your area, we are working to resolve the issue”

I laugh, this is what I live for! Almost all of my services are self hosted, I’m barely going to notice the difference!

Wrong.

When the internet went out, the power also went out for a few seconds. Four small computers host all of my services. Of those, one shutdown, and three rebooted. Of the three that ugly rebooted some services came back online, some didn’t.

30 minutes later, ISP sends out the text that service is back online.

2 hours later I’m still finding down services on my network.

Moral of the story: A UPS has moved to the top of the shopping list! Any suggestions??

    most traditional VMs do not like to have their power killed (especially non-journaling file systems).

    Why are you using a non-journaling file system in 2024 when those were common 10+ years ago?

      It’s been a while since a power cut affected my services, is this why?

      I remember having to troubleshoot mysql corruption following abrupt power loss, is this no longer a thing?

        Databases shouldn’t even need a journaling filesystem, they usually pay attention to when to use fsync and fdatasync.

        In fact journaling filesystems basically use the same mechanisms as databases only for filesystem metadata.

        I would still consider that generation of filesystem to be effort to use while regular journaling filesystems have been so ubiquitous that you need to invest effort to avoid using one.

            Maybe on some distros that is the case if you install a recent version but to get a non-journaling filesystem you literally have to partition manually to avoid using one on any distro that is still supported today and meant for full sized PCs (as opposed to embedded devices).

                If you want to use a filesystem that is so bad that it doesn’t even have journaling you need to manually select it. None of them have been using one of those by default for 10-15 years now.
