keithzgLast dpkg log on the first server was written on the 15th, doesn't look like automatic upgrades were applied anytime since, though since a lot of filesystem corruption seems to have resulted in deletions and reversions since the problem started this isn't a *hard* guarantee. But it does point to me just being a very unlucky <a class="hashtag" href="https://fediverse.keithzg.ca/tag/sysadmin" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a> in having a part fail *and* an equivalent replacement part waiting fail in the same way.

keithzg<p>Hmm is there any chance some recent Linux security patches have borked some NVMe block devices? I had a server go down yesterday because suddenly the M.2 NVMe drive in it was running into errors and automatically re-mounting as read-only (oddly in an endless loop), and then I thought "well hey good excuse to take the parts for a fast new Windows machine sitting unbuilt at the office and claim it as one of my servers instead" and so I tried to set that up and somehow, despite running much newer parts that had never been even unpackaged before, the fresh install almost immediately ran into <em>the same problem</em>.</p><p>The first one was running <a class="hashtag" href="https://fediverse.keithzg.ca/tag/ubuntu" rel="nofollow noopener noreferrer" target="_blank">#Ubuntu</a> Server 22.04, the second <a class="hashtag" href="https://fediverse.keithzg.ca/tag/debian" rel="nofollow noopener noreferrer" target="_blank">#Debian</a> 12.10. In both cases AMD CPUs, though from over 5 years apart, and in both cases Western Digital SSDs with the same gap. Probably I'm just a very unlucky <a class="hashtag" href="https://fediverse.keithzg.ca/tag/sysadmin" rel="nofollow noopener noreferrer" target="_blank">#sysadmin</a>, but it feels like there could be some shared factor here...</p>
