[Gluster-users] Switching clients to NFS
I'm looking at switching some clients from native gluster to NFS. Any advice on how to do this as transparently as possible? Can both mounts be used at the same time (so I can test NFS before switching)? I'm on a vanilla 2-way AFR config where both clients are also servers.

Re: [Gluster-users] Switching clients to NFS
if you are using version 3.3, then you will need a separate client. you cannot mount any other nfs exports/volumes on glusterfs servers. if you are using 3.2.x, then you can mount it on the same servers Regards, Rajesh Amaravathi, Software Engineer, GlusterFS RedHat Inc. - Original Message - From: Marcus Bointon mar...@synchromedia.co.uk To: gluster-users Discussion List gluster-users@gluster.org Sent: Friday, June 22, 2012 3:23:43 PM Subject: [Gluster-users] Switching clients to NFS I'm looking at switching some clients from native gluster to NFS.

Re: [Gluster-users] Switching clients to NFS
I think he is talking about 1 set of servers, having some clients mount via NFS and some mount via native gluster. I did this in a test environment with 3.2.5 and it seemed to work OK. We had four nodes initially set up as gluster native and we changed over one by one to nfs. The world did not end. But it was in a test environment. sean On 06/22/2012 05:59 AM, Rajesh Amaravathi wrote: if you are using version 3.3, then you will need a separate client. you cannot mount any other nfs exports/volumes on glusterfs servers. if you are using 3.2.x, then you can mount it on the same servers Regards, Rajesh Amaravathi, Software Engineer, GlusterFS RedHat Inc. - Original Message - From: Marcus Bointon mar...@synchromedia.co.uk To: gluster-users Discussion List gluster-users@gluster.org Sent: Friday, June 22, 2012 3:23:43 PM Subject: [Gluster-users] Switching clients to NFS I'm looking at switching some clients from native gluster to NFS.

Re: [Gluster-users] Switching clients to NFS
I have seen a few people recently saying they are using NFS instead of the Native Gluster client. I would imagine that the Gluster client would always be better and faster besides the automatic failover, but it makes me wonder what sort of problems their as experiencing with the Gluster client.

I assume it's ok to have one client mounted with nfs while the other uses native?

Re: [Gluster-users] Switching clients to NFS
I have both read specifically that people with small files basically switched to NFS to solve small-file read issues and speed issues more generally. It seems to me (from my own testing as well), that 3.3 is still not working all that well with 'small files'. An image folder with about 20k images in it takes about 20+ seconds to do an 'ls' on, and about three seconds with NFS. It was enough of a speed difference on the front-end site to make me change my thinking and start working on getting keepalived working with gluster so that I can have a consistent NFS view.

I ran FUSE mounts for a couple of months then switched to NFS. In general I saw an approx 2x improvement in read performance, and writes appeared to be a little quicker. Since my environment is 'mostly reads', as NFS utilizes the OS filesystem cache I saw a substantial drop in network traffic between Gluster nodes. I was also never able to get FUSE to mount volumes with an explicit SELinux context set. Not sure if it's a bug in FUSE on RHEL6, or just something broken with FUSE, but it just ignored the secontext= mount parameter. NFS works with this, so I was able to run SELinux in enforcing mode while using Gluster.
