Interesting table Karan!, Could you please tell us how you did the benchmark? fio or iozone orsimilar? thanks Arman.

Hi Collin, During our arbiter latency testing for completion of ops we found the below results:- an arbiter node in another data centre and both the data bricks in the same data centre, 1) File-size 1 KB (10000 files ) 2) mkdir Latency 5ms 10ms 20ms 50ms 100ms 200ms Ops Create 755 secs 1410 secs 2717 secs 5874 secs 12908 sec 26113 sec Mkdir 922 secs 1725 secs 3325 secs 8127

Hi Brandon, Can you please turn OFF client-io-threads as we have seen degradation of performance with io-threads ON on sequential read/writes, random read/writes. Server event threads is 1 and client event threads are 2 by default.

Hi gluster users, I've spent several months trying to get any kind of high performance out of gluster. The current XFS/samba array is used for video editing and 300-400MB/s for at least 4 clients is minimum (currently a single windows client gets at least 700/700 for a single client over samba, peaking to 950 at times using blackmagic speed test). Gluster has been getting me as low as

Apologies for the late reply. Further to this, if my Linux clients are connecting uing glusterfs-fuse and I have my volumes defined like this: dc1srv1:/gv_fileshare dc2srv1:/gv_fileshare dc1srv2:/gv_fileshare dc2srv2:/gv_fileshare (replica 2) How do I ensure that clients in dc1 prefer dc1srv1 and dc1srv2 while clients in dc2 prefer the dc2 servers? Is it simply a matter of ordering in

It was simple emulation of network packets on the port of the server node using tc tool tc qdisc add dev <port> root netem delay <time>ms. The files were created using dd tool (in-built in linux) and mkdir. Post the IO's we verified with no pending heals.

I managed to force stopping geo replication using the "force" parameter after the "stop" but there are still other issues related to the fact that my geo replication setup was created before I added the additional arbiter node to my replca. For example when I would like to stop my volume I simply can't and I get the following error: volume stop: myvolume: failed: Staging

Hello To my two node replica volume I have added an arbiter node for safety purpose. On that volume I also have geo replication running and would like to stop it is status "Faulty" and keeps trying over and over to sync without success. I am using GlusterFS 3.8.11. So in order to stop geo-rep I use: gluster volume geo-replication myvolume gfs1geo.domain.tld::myvolume-geo stop but it

I just tried setting: performance.parallel-readdir on features.cache-invalidation on features.cache-invalidation-timeout 600 performance.stat-prefetch performance.cache-invalidation performance.md-cache-timeout 600 network.inode-lru-limit 50000 performance.cache-invalidation on and clients could not see their files with ls when accessing via a fuse mount. The files and directories were there,

Hi all, I have a banking customer asking if CentOS is compatible on RHV4.0 as a guest VM. Based on Red Hat?s knowledge base (see link below), CentOS not supported guest OS. However, VMware say on their official document, CentOS is a compatible guest OS (see link below). So, in my customer's mind, CentOS cannot be used as a guest OS in RHV cause it is not compatible, which I find it hard to

Hi all, ? ? One more thing, we have 3 apps servers with the gluster on it, replicated on 3 different gluster nodes. (So the gluster nodes are app servers at the same time). We could actually almost work locally if we wouldn't need to have the same files on the 3 nodes and redundancy :) ? Initial cluster was created like this: ? gluster volume create www replica 3 transport tcp

Hi, OK. I tried your suggestion. I modified the dovecot config file "10-logging.conf", like so: log_path = syslog and mail_debug = yes It appears that the logging goes to "/var/log/maillog", not "messages" as I expected. Restarting service dovecot produces info in the "maillog" file showing the restart: ... Jan 22 15:20:14 coe dovecot: imap: Server

Hi, I have a question. I have dovecot 2.0.9 running on a CentOS 6.6 email server for a small department, ~15 users. amavis and postfix are also enabled. It appears that amavis invokes spamassassin, which tags incoming spam email. All email is then put into users local inbox directory, regardless of spam tag X-Spam_Flag value of YES or NO. I want instead to redirect spam to a special directory.

Hello Joe, ? ? I really appreciate your feedback, but I already tried the opcache stuff (to not valildate at all). It improves of course then, but not completely somehow. Still quite slow. ? I did not try the mount options yet, but I will now! ? ? With nfs (doesnt matter much built-in version 3 or ganesha version 4) I can even host the site perfectly fast without these extreme opcache settings.

Hello, I have installed GlusterFS one month ago, and replication have many issues : First of all, our infrastructure, 2 storage array of 8Tb in replication mode... We have our backups file on this arrays, so 6Tb of datas.
