group write permissions not being respected
Hi
We have just migrated our data to a new file server (more space, old
server was showing its age). We have a volume for collaborative use,
based on group membership. In our new server, the group write
permissions are not being respected (e.g. the owner of a directory can
still write to that directory but any other member of the associated
group cannot, even though the directory clearly

Slow write times to gluster disk
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.

Sorry this took so long, but we had a real-time forecasting exercise

Slow write times to gluster disk
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

Slow write times to gluster disk
Hi,
We noticed a dramatic slowness when writing to a gluster disk when
compared to writing to an NFS disk. Specifically when using dd (data
duplicator) to write a 4.3 GB file of zeros:
* on NFS disk (/home): 9.5 Gb/s
* on gluster disk (/gdata): 508 Mb/s
The gluser disk is 2 bricks joined together, no replication or anything
else. The hardware is (literally) the same:
* one server with

Slow write times to gluster disk
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.

Slow write times to gluster disk
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

We have been trying back-up a glusterfs (v3.1.4) area using
the Tivoli TSM software to an off-site area. The back-up

Hi Soumya,
(1) In http://mseas.mit.edu/download/phaley/GlusterUsers/TestNFSmount/
I've placed the following 2 log files

The first has repeated messages about nfs disconnects. The second had
the <fuse_mnt_direcotry>.log name (but not much information).

For glusterfs 3.7, nfs-ganesha-2.3-* version can be used.

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

The results are in the same place

Slow write times to gluster disk
Hi Soumya,
We just had the opportunity to try the option of disabling the
kernel-NFS and restarting glusterd to start gNFS. However the gluster
demon crashes immediately on startup. What additional information
besides what we provide below would help debugging this?
Thanks,
Pat

NFS not recognizing available file space
Hi,
I have a server running under CentOS 5.8 and I appear to be in a
situation in which the NFS file server is not recognizing the available
space on a particular disk (actually a hardware RAID-6 of 13 2Tb disks).
If I try to write to the disk I get the following error message

touch: cannot touch `dum': No space left on device

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
