00:17 sergem major: about my earlier question (removing obsolete alternative hostnames of the peer), after some search it seems the feature was added by this commit: https://github.com/gluster/glusterfs/commit/fde2b737 and function gd_add_address_to_peer(), but there's no gd_remove_address_from_peer(), so I guess there's no way to remove it.
00:17 glusterbot Title: glusterd: Improvements to peer identification · gluster/glusterfs@fde2b73 · GitHub (at github.com)
00:17 sergem In my case I'll probably keep the obsolete hostname there, as it works anyway, and I don't want to break it. But that could be a great feature for renaming hosts or changing IPs... Maybe one day there will be `gluster peer hostname remove ...` Thanks for your help! You've pointed me to the right direction!

08:05 jsierles good day, gluster
08:06 jsierles i just setup a replica volume without any perf tuning, on a gbit ethernet with no traffic. overnight i setup an rsync to copy 90GB of data (lots of dirs and small files) to it, and it hasn't finished yet. Just wondering how I can track performance
08:10 jsierles i've been reading that NFS is much faster for writes. true?

08:35 jkroon jsierles, my experience has been that nfs performs better, i suspect in part due to no FUSE.
08:35 jsierles for reads and writes?

08:42 genunix Hello, I have a little question, maybe there's someone who can point me to proper way how to achieve it - I need to convert distributed volume to distributed replicated (as at the beginning I will have single-node and then need to add more nodes into pool and start replication). I didn't find resource describing how to convert to replicated and it's not possible to create volume with replica 1.

09:10 yoda1410 i have a small question about topology migration
09:11 yoda1410 it's possible to migrate - online - from a topology distributed to distributed + replica ?
09:14 genunix yoda1410: it seems to be the same question as mine.. :-)
09:16 yoda1410 probably ... but I join the chan only now ;)

09:49 jkroon jsierles, i've never done the comparison for read/write.  I have however experienced as well that in general even something as simple as a find can potentially be 100x slower via gluster (fuse) than on the filesystem itself.
09:49 jsierles jkroon: alright. i'm putting 90GB of software on there, with tons of small files, and a top-level directory with 8000 directories
09:50 jsierles so it's understandable
09:50 jkroon indeed :)
09:51 jkroon i'd expect an ls on that to take a few seconds at the top level.  and small-file performance are horrible on most filesystems (I've got a 41.5TB ext4 one that's 98% full with an average file size of 200KB ... you can imagine, gluster is worse)

09:53 jsierles i'm not too worried about writes. more concerned that reads are performant or cached, as some of these paths will be searched a lot

11:07 jsierles if I want NFS support on my server, do I need to setup ganesha?

11:12 WebertRLZ joined #gluster
11:14 jsierles i see ganesha is preferred over gluster NFS
11:18 jsierles but looks like it requires a lot of setup. corosync and pacemaker?
11:27 baber joined #gluster
11:36 ndevos jsierles: NFS-Ganesha offers more features than Gluster/NFS, if you need only simple NFSv3 access, Gluster/NFS is still an option
11:36 jsierles ndevos: OK. are the docs accurate about getting NFS ganesha setup? I need to install corosync and pacemaker?
11:36 ndevos jsierles: we're deprecating Gluster/NFS, and strongly suggest to use NFS-Ganesha for new deployments to be future ready
11:36 jsierles fine with me. just want to see how to set it up
11:37 ndevos jsierles: you only need corosync/pacemaker if you want high-availability NFS, if you use a single NFS-Ganesha server, you dont need it
11:37 jsierles i'm currently running the cluster in docker on coreos, using ubuntu and the glusterfs 3.11 PPA
11:38 jsierles i see. does nfs-ganesha actually mount a volume over fuse, then serve it over nfs?
11:38 jsierles my only reason for looking at nfs is for performance. as many here have mentioned it's faster than the fuse drier

12:03 jsierles i have 2 replicas, and while copying a large set of data, i noticed one replica has 17GB, and the other 28GB
12:04 jsierles the server I mounted the fuse mount from has 17GB. i would expect the other server to have less.
12:04 jsierles and eventually balance out?

15:00 jarbod Hello, since i upgrade gluster from 3.8 to 3.10 i have now two ACTIVE status (geo-replication) for the same volume for a replicated volume (2). Before i had only one Active and on Passive. Anyone know why ?
