        yvanzo: did it work? I see folders on the nodes?
      • yvanzo
        It seems so, I’m setting up a standalone Solr instance on wolf to try loading them.
      • Also, good news is that the new Solr incremental backups should make dump creation much faster.
      • atj
        are you just syncing them from all the nodes into one folder?
      • yvanzo
        no sync at this stage
      • just pre-making folders on all nodes beforehand
      • atj
        :/
      • yvanzo
        for example, recording has 4 shards, each with a different leader, I just sent one query and they all did generate the appropriate backup files.
      • (one query to only one node)

        [23:39] <aerozol[m]> Thanks yvanzo, copied (with slight adjustment) to X
      • can we not call twitter x? can we be social disobedient enough to elon and his cronies to *continue* to call it twitter?

        I would very much hope there's no twitter/x in 5 years, much less 10 or 20 :p
      • ApeKattQuest
        I would hopw so? i go friends there and a community
      • right now it's already falling apart because of everything

        <05rustynova> I personally don't think Elon will remain CEO for long, but the platform wouldn't die. And either I call it twitter, or "X (formerly known as twitter)" because it's funnier that way
      • atj
        i think refusing to use a platform owned by a white supremacist would be a more suitable form of "social disobedience" than quibbling about names
      • tykling
        ^ this times 1000
      • ApeKattQuest
        rustynova :D
      • well "not using it" means jsut "I won't be able to interact with these people i want to interact with" so that's moot
      • atj
        well in that case don't try to police what other people do then
      • ApeKattQuest
        also they don't care about users not using it, they *do* care about their dumb brandname not being used
      • "can we not call twitter x?" = policing, now apparently
      • it was a polite bequest, it was not an affront to you, personally :P
      • stop taking it that way ;)
      • atj
        me criticizing bad takes is not "taking it personally"
      • but hey, I'm sure Elon will ban all the Nazis and stop retweeting Ian Miles Cheong if you call it Twitter enough
      • ApeKattQuest
        well that's what it comes off as. also who are you to decide whats a bad take or not :P
      • he definitly wont
      • reosarevok
        I expect unless something changes, communities that currently live on Twitter will probably move elsewhere eventually
      • aerozol[m] has quit
      • I guess the main question is what the somewhere is :)
      • ApeKattQuest
        yep, they definitely will, but the problem is that it will splinter, and that makes me unhappy so I'm a bit ornery :wry:

      • lucifer
        will get worse next month, 50-55 even. should be better once the monsoon rains start by july.

        ApeKattQuest: I feel like calling it X (which nobody knows) does more harm to Elon etc?
      • I can use ‘X (formerly Twitter)’ like most places do, when the word count allows 👍️
      • reosarevok
        The X formerly known as Twitter

        yvanzo: i'll try and get NFS set up today
      • will mount the share under `/var/lib/solr/backups`
      • then i need to install rsync and set up the SSH key. might be best if we generate a new one?
      • *rrsync
      • yvanzo
        atj: The new backup format can no longer be tampered with to load into Solr standalone mode. Will have to set SolrCloud mode even for mirrors.
      • Thanks, it will always be useful to have an NFS share in case we actually need backups.
      • Yes to generating a new key.
      • twodoorcoupe has quit
      • atj: Not even sure if that can be restored in another cluster.
      • atj
        yvanzo: that is stretching the meaning of the word "backup" if true
      • yvanzo
        I mean the backup might also include the distribution on nodes.
      • atj: I noticed that `solr` user/group IDs vary across the nodes.
      • atj
        hmm, not sure how that happened
      • yvanzo: i will need to shutdown solr on each box to fix this
      • mr44er[m]
        nfs3 vs nfs4 maybe?
      • atj
        nah, it's an error on my part
      • mr44er[m]
        kk
      • atj
        i set the uid / gid to be 998 in the ansible configuration, but other packages took it
      • yvanzo
        atj: Does beta.mb.o have to be switched back to Solr 7 in the meantime?
      • atj
        yvanzo: i can do it one by one, so no
      • it will be a good test of the resiliency actually
      • yvanzo
        Yes, we should see some changes in shards’ leaders.
      • I saved the collection status locally for comparison.
      • atj
        yvanzo: great thanks. i will start on node 1 now
      • yvanzo: node 1 is back
      • yvanzo
        nodes 2, 3 & 5 took the lead on its four shards
      • atj
        I need to nip out for a little bit now, but the process is straightforward so I'll just go through the others one by one when I get back
      • yvanzo
        Thanks!
      • atj
        thanks for noticing, much better to fix this now!

        atj: lucifer: zas: how can we move the ipv6 support issue forward in order to complete the matrix migration?
      • lucifer
        mayhem: i think atj was looking into that but currently busy with solr stuff.
      • twodoorcoupe joined the channel
      • atj
        zas: do you know if we can assign 2 IPv6 /64 subnets to a VM?
      • lucifer
        mayhem: lol prediction came true too soon. https://www.ndtv.com/india-news/delhi-hits-52-3...
      • zas
        atj: I don't think so. Why would it be needed?
      • atj
        zas: need to delegate a prefix to the matrix irc bridge
      • lucifer
        atj, zas: not sure if it makes sense, but would it possible to to use a /48 or /32 subspace inside the /64 already assigned to the vm?
      • atj
        lucifer: i had another look at the issue i linked before, and it looks like that's possible
      • however the docker docs are a bit unclear "the base value for IPv6 needs a minimum prefix length of /64. This is due to an integer overflow in the Docker daemon"
      • a great couple of notes there "defining an excessive number of subnets causes the daemon to consume all available memory."
      • Kladky has quit
      • lucifer
        atj: ah sorry, i had it the other way around i think. i meant can we use a subdivision of the /64 subnet in docker and matrix?
      • atj
        lucifer: no i think it's me :P
      • i will need to enable ipv6 support in docker and test some things
      • lucifer
        sounds good, let me know if i can help.
      • atj
        lucifer: hmm, this makes me think IP_FREEBIND won't work inside Docker
      • tbh i'd rather use a container platform that has sensible networking support than battle with Docker
      • lucifer
        what do you think about running the service without docker?
      • atj
        maybe just run the irc bridge in a systemd-nspawn container?
      • lucifer
        i am not sure how to do that. 😅
      • atj
        i think using the ansible role with docker is best from a maintenance perspective
      • sticking one isolated component in a separate container shouldn't be an issue but i need to check out how it works
      • mayhem
        lucifer: 😬
