@hexa:lossy.networkhexaor linbit is19:05:31
@hexa:lossy.networkhexaI don't want to go back to drbd 😄 19:05:45
@hexa:lossy.networkhexaso what is linstor19:05:53
@hexa:lossy.networkhexa

LINSTOR has multiple uses, but it is typically used to manage a large number of DRBD replicated storage resources

19:06:53
@adam:robins.wtfadamcstephensi've never used drbd 🤷‍♂️19:07:16
@hexa:lossy.networkhexaway back, when we had two node hypervisor clusters over 10y ago19:07:30
@adam:robins.wtfadamcstephensyeah, gluster is also an old filesystem. but it's dying 19:10:00
@adam:robins.wtfadamcstephensi think the real problem is clustered/distributed filesystems are hard and RH is probably the only one making any serious money with them19:12:24
@adam:robins.wtfadamcstephens(in the open source space)19:12:40
@hexa:lossy.networkhexaso what clusterlvm does is make sure that in a clustered lvm setup that only one node can write metadata19:16:09
@hexa:lossy.networkhexathey share the same block device, which can be attached by any means, but most likely iscsi19:16:27
@hexa:lossy.networkhexathat only makes sense if you have a chonky multihead storage cluster19:16:41
@hexa:lossy.networkhexaI'd rather do hyperconverged setups, and that is where ceph shines19:17:06
@hexa:lossy.networkhexathe main benefit is that I can rely on commodity hardware19:18:57
@hexa:lossy.networkhexaanyway, one weird thing I imagined is zfs send/recv style migrations19:19:26
@hexa:lossy.networkhexaI think proxmox could do that19:19:36
@hexa:lossy.networkhexaand it might be appealing since zfs has alot less moving parts than ceph19:19:47
@adam:robins.wtfadamcstephensat least for non-clustered incus, i think it does use zfs send/recv for migrations19:34:21
@adam:robins.wtfadamcstephensit may for clustered too when it's not a shared volume19:34:42
@adam:robins.wtfadamcstephens * it may for clustered too when it's not a shared pool19:34:45
@cmspam:matrix.orgcmspam joined the room.19:34:51
@cmspam:matrix.orgcmspamHello, everyone.19:40:11

In reply to @adam:robins.wtf
I’m also still hoping to deprecate lxd. I’ve just been waiting for incus LTS 
i'll make it seperate packages then

@cmspam:matrix.orgcmspamI figured it out. Here is the pull request for the new test.20:36:35

I was expecting you to add that to your other PR. :)
21:34:42
@cmspam:matrix.orgcmspam adamcstephens 🐝: Yes, it would have made much more sense to put it there :D
The code review you put requesting changes to requires, the changes have been fulfilled. Have I submitted that correctly and it's back to you, or I need to do something further to indicate it's implemented in github?
