So, my crawler has been running for 5 years, and it also pulls data from other sources like the-federation.info, fediverse.observer, fedidb.com etc. Its database has 44142 alive nodes and 777384 dead ones, so the answer is 5.4%. If .gab.best and .cheeseland.xyz are excluded, then only 98621 nodes are dead and the answer is 30.9%.
Someone in the thread suggested that nodes might be pruning their peers lists from dead nodes. Judging by the negligible difference between Evan's number and my number, no pruning is done.
BTW, my crawler currently tracks 22 newly discovered nodes, i.e. ones that were seen in someone's peers list but whose NodeInfo hasn't been checked yet. I'm happy the Fediverse keeps growing _^

Technically we're all living outside Europa :P
Moomin is fairly popular in Eastern Europe, every 90s kid heard about them for sure, but not everyone actually read the books.

Wrapstodon says I created posts more often than replies, and this makes me somewhat sad. In my first years on Fedi I was very actively seeking posts where I could meaningfully contribute, and it was super enjoyable. Subscribed to lots of interesting people that way, too.
After a while, it became too much, so I hid boosts or even unsubscribed from folks, and also scaled down my commenting activity. I should really get back into the latter, because it was pretty rewarding.

Is there any know-how about creating filesystems on top of RAID1? Both XFS and ext4 top out at 35 MB/s for me even though the block device below it is capable of 135 MB/s (yes, 4x difference!) This even with an absurdly large I/O request sizes like 512KB.
The disks are old-ish SATA drives with 512-byte sectors. XFS seem to use 512b sectors while ext4 picked 4k. They're connected via USB DAS, with dm-integrity on top of each disk, which are then combined into mdadm raid1, and encrypted with LUKS.
I confirmed with fio that the slowdown happens on the filesystem level, not LUKS or anywhere below it.
The only advice I found online is about alignment, but with 512KB requests it shouldn't be an issue because that's way larger than any of the block/sector sizes involved. I must be missing something, but what is it?
