Re: [Gluster-users] hanging httpd processes.

Hi, As you have mentioned client/server version in thread it shows package version are different on both(client,server). We would recommend you to upgrade both servers and clients to rhs-3.10.1. If it is not possible to upgrade both(client,server) then in this case it is required to upgrade client

Hi Yong, Gluster uses the openssl library, which supports SSL 3.0 and TLS versions 1.0,1.1,1.2. I actually don't know if its dynamically linked against the openssl library nor what version of the openssl lib gluster has been tested with. That is important info to know that is currently undocumente

Re: [Gluster-users] hanging httpd processes.

Since things are in production making upgrades needs to be scheduled so this may take a while before I can get everything up to 3.10. I have set the write-behind option to off on the servers but do I need to restart the servers or can I just get away with umount/mount the clients? Thank you f

Re: [Gluster-users] Node count constraints with EC?

Ok, I think I see my error. The rule, near as I can tell, is actually total/parity>2. So, 4+2 gives 6/2=3, and therefore is ok. Eventually I’ll get all this straight! Terry > On Mar 30, 2017, at 23:13, Ashish Pandey wrote: > > Terry, > > It is (data/parity)>=2. You can very well create

Thanks Amar, I’ll consider your recommendations. But why performance is totally different on two nodes? Will data be written to both nodes at the same time? From: Amar Tumballi Sent: Friday, March 31, 2017 3:14 PM To: Alvin Starr Cc: gluster-u

[Gluster-users] Deletion of old CHANGELOG files in .glusterfs/changelogs

Hi, I am using geo-replication since now over a year on my 3.7.20 GlusterFS volumes and noticed that the CHANGELOG. in the .glusterfs/changelogs directory of a brick never get deleted. I have for example over 120k files in one of these directories and it is growing constantly. So my question,

As I understand it, only new files will be sharded, but simply renaming or moving them may be enough in that case. I'm interested in the arbiter/sharding bug you've mentioned. Could you provide any more details or a link? Cheers, D On 30 March 2017 at 20:25, Laura Bailey wrote: > I can't answ
