If .gab.best and .cheeseland.xyz are excluded, then only 98621 nodes are dead and the answer is 30.9%.<br/><br/>Someone in the thread suggested that nodes might be pruning their peers lists from dead nodes. Judging by the negligible difference between Evan&#39;s number and my number, no pruning is done.<br/><br/>BTW, my crawler currently tracks 22 newly discovered nodes, i.e. ones that were seen in someone&#39;s peers list but whose NodeInfo hasn&#39;t been checked yet. I&#39;m happy the Fediverse keeps growing _^<br/><br/><span itemprop="mentions" itemscope itemtype="https://schema.org/Person"><a itemprop="url" href="/npub1xselj43f4mq6e4tmadr6ex9s2xfdp34wqupn27n2ufd6clv3mqkqhflgk3" class="bg-lavender dark:prose:text-neutral-50 dark:text-neutral-50 dark:bg-garnet px-1"><span>wakest ⁂</span> (<span class="italic">npub1xse…lgk3</span>)</a></span> <span itemprop="mentions" itemscope itemtype="https://schema.org/Person"><a itemprop="url" href="/npub176495h5jd2deymed6taalm3mwgcg9k9qf6z03vac2wp84htwvzvs66nuj0" class="bg-lavender dark:prose:text-neutral-50 dark:text-neutral-50 dark:bg-garnet px-1"><span>Evan Prodromou 🇨🇦🇺🇸🇬🇷🇵🇸</span> (<span class="italic">npub1764…nuj0</span>)</a></span> 2026-10-03T08:31:16Z https://nostr.now/nevent1qqsxvyr2sr2vva0ece2khvg5apv90a9dqf7aw3hwp28reysrygmwxpczyznfryms9nudu74ekeepuvvakrp0s2zc04a8twtwth9tvfehsz2tzvfexcc In reply to <a href='/nevent1qqsp8ks9p8fy5denkvd47hrp7z5zhkx0fx2cf56kvj8n85azjezv8uq934pdf'>nevent1q…4pdf</a><br/>_________________________<br/><br/>Technically we&#39;re all living outside Europa :P<br/><br/>Moomin is fairly popular in Eastern Europe, every 90s kid heard about them for sure, but not everyone actually read the books. 2026-08-09T06:59:55Z https://nostr.now/nevent1qqszx0nlj44wd08vrrnpzx5spt0mkf3yt94tq8srrwmxu0hl9xgqgdszyznfryms9nudu74ekeepuvvakrp0s2zc04a8twtwth9tvfehsz2tzzrv43z 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.<br/><br/>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. 2025-12-28T07:42:01Z https://nostr.now/nevent1qqs8g9yhqmnv70xrancrug8yuen8rfvwgj4f5m7ua6e3y92dr5hevhczyznfryms9nudu74ekeepuvvakrp0s2zc04a8twtwth9tvfehsz2tzqlmlga 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.<br/><br/>The disks are old-ish SATA drives with 512-byte sectors. XFS seem to use 512b sectors while ext4 picked 4k. They&#39;re connected via USB DAS, with dm-integrity on top of each disk, which are then combined into mdadm raid1, and encrypted with LUKS.<br/><br/>I confirmed with fio that the slowdown happens on the filesystem level, not LUKS or anywhere below it.<br/><br/>The only advice I found online is about alignment, but with 512KB requests it shouldn&#39;t be an issue because that&#39;s way larger than any of the block/sector sizes involved. I must be missing something, but what is it?<br/><br/>#mdadm #raid #ext4 #xfs #AskFedi 2025-01-10T18:38:01Z
