Hi Soumya, (1) In http://mseas.mit.edu/download/phaley/GlusterUsers/TestNFSmount/ I've placed the following 2 log files etc-glusterfs-glusterd.vol.log gdata.log The first has repeated messages about nfs disconnects. The second had the <fuse_mnt_direcotry>.log name (but not much information). (2) About the gluster-NFS native server: do you know where we can find documentation on

Hi Soumya, When I originally did the tests I ran tcpdump on the client. I have rerun the tests, doing tcpdump on the server tcpdump -i any -nnSs 0 host 172.16.1.121 -w /root/capture_nfsfail.pcap The results are in the same place http://mseas.mit.edu/download/phaley/GlusterUsers/TestNFSmount/ capture_nfsfail.pcap has the results from the failed touch experiment capture_nfssucceed.pcap has

Hi All, Decided to try another tests of gluster mounted via FUSE vs gluster mounted via NFS, this time using the software we run in production (i.e. our ocean model writing a netCDF file). gluster mounted via NFS the run took 2.3 hr gluster mounted via FUSE: the run took 44.2 hr The only problem with using gluster mounted via NFS is that it does not respect the group write permissions which

Hi Guys, I was wondering what our next steps should be to solve the slow write times. Recently I was debugging a large code and writing a lot of output at every time step. When I tried writing to our gluster disks, it was taking over a day to do a single time step whereas if I had the same program (same hardware, network) write to our nfs disk the time per time-step was about 45 minutes.

Are you sure using conv=sync is what you want? I normally use conv=fdatasync, I'll look up the difference between the two and see if it affects your test. -b ----- Original Message ----- > From: "Pat Haley" <phaley at mit.edu> > To: "Pranith Kumar Karampuri" <pkarampu at redhat.com> > Cc: "Ravishankar N" <ravishankar at redhat.com>,

Hi, Today we experimented with some of the FUSE options that we found in the list. Changing these options had no effect: gluster volume set test-volume performance.cache-max-file-size 2MB gluster volume set test-volume performance.cache-refresh-timeout 4 gluster volume set test-volume performance.cache-size 256MB gluster volume set test-volume performance.write-behind-window-size 4MB gluster

Hi All, A follow-up question. I've been looking at various pages on nfs-ganesha & gluster. Is there a version of nfs-ganesha that is recommended for use with glusterfs 3.7.11 built on Apr 27 2016 14:09:22 CentOS release 6.8 (Final) Thanks Pat On 07/05/2017 11:36 AM, Pat Haley wrote: > > Hi Soumya, > > (1) In

Hi Ben, Sorry this took so long, but we had a real-time forecasting exercise last week and I could only get to this now. Backend Hardware/OS: * Much of the information on our back end system is included at the top of http://lists.gluster.org/pipermail/gluster-users/2017-April/030529.html * The specific model of the hard disks is SeaGate ENTERPRISE CAPACITY V.4 6TB

Hi, Just before the Thanksgiving break, we enabled quotas on the /home areas on the mseas-data server (running CentOS 5.8), using the following line in the updated /etc/fstab /dev/mapper/the_raid-lv_home /home ext3 defaults,usrquota,grpquota 1 0 Following the Thanksgiving reboot of mseas-data we have been experiencing problems with svn on mseas (our front-end machine, running

Hi, I was wondering if there were any additional test we could perform to help debug the group write-permissions issue?

I see

Hi Soumya, One example, we have a common working directory dri_fleat in the gluster volume drwxrwsr-x 22 root dri_fleat 4.0K May 1 15:14 dri_fleat my user (phaley) does not own that directory but is a member of the group dri_fleat and should have write permissions. When I go to the nfs-mounted version and try to use the touch command I get the following ibfdr-compute-0-4(dri_fleat)%

Hi Soumya, I just noticed some of the notes at the bottom. In particular * Till glusterfs-3.7, gluster-NFS (gNFS) gets enabled by default. The only requirement is that kernel-NFS has to be disabled for gluster-NFS to come up. Please disable kernel-NFS server and restart glusterd to start gNFS. In case of any issues with starting gNFS server, please look at
