I think I have the same problems as: http://gluster.org/pipermail/gluster-users/2011-June/007980.html and http://gluster.org/pipermail/gluster-users/2011-May/007697.html Recently I installed Glusterfs 3.2.0 on four workstations which share a total of 28TB of disk-space between them for batch processing of FMRI and DTI data. Had the same setup between three workstations and 9TB with Glusterfs 3.0.4 for over a year, but the hard-disk pool was to small. The three "old" workstations from the old cluster and two more will also access the 28TB pool. OS: Scientific Linux 6 Glusterfs 3.2.0 and 3.2.1 compiled from source rpm I've been testing the new setup for over a week now, but it seemed unstable, Glusterfs clients would stop responding and tasks hung without being able to kill -9. Only a reboot would stop the tasks. a kill of the Glusterfs client and a mount afterwards would make the gluster storage accessible again. One of the tasks is converting a medical image format called nifti to another format called analyze. We use a application included in a package called mrtrix (2.9.0) for this. The application is mrconvert. -A conversion of a large nifti file (256MB) to a analyze file will hang application and the Gluster fuse client - A small one (10MB) will work. - If I convert it reading from the Gluster storage to a local disk everything works fine. - Reading from a local disk to the Gluster storage will hang the application and gluster fuse client - disabling the quick-read does nothing. Errors are the same as a in the second post above, I can post them Monday. I did a strace on a functioning and a none functioning convert and the application hangs on the last close like: munmap ............. close(4 The conversion was completed. I tried 3.2.0, 3.1.4 and 3.2.1 and all of them have the same problem. I went back to 3.0.8 and this is functioning. -- Marc Geerlings Application Manager Research Department of Radiology Maastricht University Medical Center P.O.
