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>, gluster-users at gluster.org, "Steve Postma" <SPostma at ztechnet.com>, "Ben > Turner" <bturner at redhat....

...e: there is one physical server that hosts both the NFS and the GlusterFS areas Latest tests I have had time to run the tests for one of the dd tests you requested to the underlying XFS FS. The median rate was 170 MB/s. The dd results and iostat record are in http://mseas.mit.edu/download/phaley/GlusterUsers/TestXFS/ I'll add tests for the other brick and to the NFS area later.

Slow write times to gluster disk
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)% touch dum touch: cannot touch `dum': Permission denied One of the...

Slow write times to gluster disk
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 the results from the successful touch experiment The brick log files are there too. I believe we are using kernel-NFS exporting a fuse mounted gluster volume. I am h...
