similar to: Poor performance with AFR

Hi - I already have an NFS server in production which shares Web data for a 4-node Apache cluster. I'd like to switch to GlusterFS. Do I have to copy the files from the NFS storage to a GlusterFS one, or may it work if I just install GlusterFS on that server, configuring a GFS volume to the existing storage directory (assuming, of course, the NFS server is shuuted down and not used

I was wondering if anyone would be able to shed some light on how a file could end up with inconsistent md5sums on Gluster backend storage. Our configuration is running on Gluster v3.1.5 in a distribute-replicate setup consisting of 8 bricks. Our OS is Red Hat 5.6 x86_64. Backend storage is an ext3 RAID 5. The 8 bricks are in RR DNS and are mounted for reading/writing via NFS automounts.

I've got configuration which in simple includes combination of afrs and unify - servers exports n[1-3]-brick[12] and n[1-3]-ns and client got cluster configuration: volume afr-ns type cluster/afr subvolumes n1-ns n2-ns n3-ns option data-self-heal on option metadata-self-heal on option entry-self-heal on end-volume volume afr1 type cluster/afr subvolumes n1-brick2

Hi all, I have 4 glusterd servers running a single glusterfs volume. The volume was created using the gluster command line, with no changes from default. The same machines all mount the volume using the native glusterfs client: [root at localhost ~]# gluster volume create datastore replica 2 transport tcp 192.168.253.1:/glusterfs/primary 192.168.253.3:/glusterfs/secondary

Hey Richard, Could you share the following informations please? 1. gluster volume info <volname> 2. getfattr output of that file from all the bricks getfattr -d -e hex -m . <brickpath/filepath> 3. glustershd & glfsheal logs Regards, Karthik On Thu, Oct 26, 2017 at 10:21 AM, Amar Tumballi <atumball at redhat.com> wrote: > On a side note, try recently released health

On a side note, try recently released health report tool, and see if it does diagnose any issues in setup. Currently you may have to run it in all the three machines.

To test gluster's behavior under heavy load, I'm currently doing this on two machines sharing a common /mnt/gfs gluster mount: ssh bal-6.example.com apt-get install dbench && dbench 6 -t 60 -D /mnt/gfs ssh bal-7.example.com apt-get install dbench && dbench 6 -t 60 -D /mnt/gfs One of the processes usually dies pretty quickly like this: [608] open

Hi... Started playing with gluster. And the heal functions is my "target" for testing. Short description of my test ---------------------------- * 4 replicas on single machine * glusterfs mounted locally * Create file on glusterfs-mounted directory: date >data.txt * Append to file on one of the bricks: hostname >>data.txt * Trigger a self-heal with: stat data.txt =>

I know that this is not the appropriate place :). You know someone can alternative to gluserfs ?:) -------------- next part -------------- An HTML attachment was scrubbed... URL: <http://supercolony.gluster.org/pipermail/gluster-users/attachments/20090107/63b68a0d/attachment.html>

Dear Members, Even though Gluster team is growing at a steady phase, our aggressive development schedule out phases our resources. We need to expand and also maintain a 1:1 developer / QA engineer ratio. Our major development focus in the next 8 months will be towards: * Large scale regression tests (24/7/365) * Web based monitoring and management * Hot upgrade/add/remove of storage nodes

Are there known performance issues with using glusterfs on software raid? I've been playing with a variety of configs (AFR, AFR with Unify) on a two server setup. Everything seems to work well, but performance (creating files, reading files, appending to files) is very slow. Using the same configs on two non-software raid machines shows significant performance increases. Before I go a

Hi, everyone. Its nice meeting you. I am poor at English.... I am writing this because I'd like to update GlusterFS to 3.2.2-1,and I want to change from gluster mount to nfs mount. I have installed GlusterFS 3.2.1 one week ago,and replication 2 server. OS:CentOS5.5 64bit RPM:glusterfs-core-3.2.1-1 glusterfs-fuse-3.2.1-1 command gluster volume create syncdata replica 2 transport tcp

Hi All. Hoping you can help me with a healing problem. I have one file which didn't self heal. it looks to be a problem with a directory in the path as one node says it's dirty. I have a replica volume with arbiter This is what the 3 nodes say. One brick on each Node1 getfattr -d -m . -e hex /path/to/dir | grep afr getfattr: Removing leading '/' from absolute path names

Hi everyone, I'm playing with Gluster3.3b2, and everything is working fine when uploading stuff through swift. However, when I enable quotas on Gluster, I randomly get permission errors. Sometimes I can upload files, most times I can't. I'm mounting the partitions with the acl flag, I've tried wiping out everything and starting from scratch, same result. As soon as I
