Dear all, I'm rather new to glusterfs but have some experience running lager lustre and beegfs installations. These filesystems provide active/active failover. Now, I discovered that I can also do this in glusterfs, although I didn't find detailed documentation about it. (I'm using glusterfs 3.10.8) So my question is: can...

Hi Stefan, I think what you propose will work, though you should test it thoroughly. I think more generally, "the GlusterFS way" would be to use 2-way replication instead of a distributed volume; then you can lose one of your servers without outage. And re-synchronize when it comes back up. Chances are if you weren't using the SAN volumes; you could have purchased two servers each with enough disk to make...

Hi Alex, Thank you for the quick reply! Yes, I'm aware that using ?plain? hardware with replication is more what GlusterFS is for. I cannot talk about prices where in detail, but for me, it evens more or less out. Moreover, I have more SAN that I'd rather re-use (because of Lustre) than buy new hardware. I'll test more to understand what precisely "replace-brick" changes. I understand the mod...

how about gluste's own client(s)? You mount volume (locally to the server) via autofs/fstab and watch for inotify on that mountpoing(or path inside it). That is something I expected was out-of-box.

1) one peer, out of four, got separated from the network, from the rest of the cluster. 2) that unavailable(while it was unavailable) peer got detached with "gluster peer detach" command which succeeded, so now cluster comprise of three peers 3) Self-heal daemon (for some reason) does not start(with an attempt to restart glusted) on the peer which probed that fourth peer. 4) fourth unavailable peer is still up & running but is inaccessible to oth...

Hi all! I have setup a replicated/distributed gluster cluster 2 x (2 + 1). Centos 7 and gluster version 3.12.6 on server. All machines have two network interfaces and connected to two different networks, 10.10.0.0/16 (with hostnames in /etc/hosts, gluster version 3.12.6) 192.168.67.0/24 (with ldap, gluster version 3.13.1) Gluster cluster was cr...

Marcus, Can you share server-side gluster peer probe and client-side mount command-lines.

Hey guys, I've recently implemented gluster to share webcontent read-write between two servers. Version : glusterfs 3.0.4 built on Apr 19 2010 16:37:50 Fuse : 2.7.2-1ubuntu2.1 Platform : ubuntu 8.04LTS I used the following command to generate my configs: /usr/local/bin/glusterfs-volgen --name repstore1 --raid...

These errors are because not having glusternw assigned to the correct interface. Once you attach that these errors should go away. This has nothing to do with the problem you are seeing. sahina any idea about engine not showing the correct volume info ?

Hi, I am able to recreate the issue and here is my RCA. Maximum value i.e 32767 is being overflowed while doing manipulation on it and it was previously not taken care properly. Hence glusterd was crashing with SIGSEGV. Issue is being fixed with " https://bugzilla.redhat.com/show_bug.cgi?id=1454418" and being backported as well.

Hello Atin, I've gotten around to this and was able to get upgrade done using 3.7.0 before moving to 3.11. For some reason 3.7.9 wasn't working well. On 3.11 though I notice that gluster/nfs is really made optional and nfs-ganesha is being recommended. We have plans to switch to nfs-ganesha on new clusters but would like to have glusterfs-gnfs on existing clusters so a seamless upgrade without downtime is possible.
