I ran some benchmarks last week using 2.0.8. Single server with 8 Intel e1000e bonded mode=balance-alb All worked fine and I got some good results using 8 clients. All Gigabit. The benchmarks did 2 passes of IOZONE in network mode using 1-8 threads per client and using 1 - 8 clients. Each client used 32Gbyte files. All jobs completed successfully. This takes about 32 hours to run through all cases. Yesterday I updated to 3.0.0 (server and clients) and re-configured the server and client vol files using glusterfs-volgen (renamed some of the vol names). RedHat EL5 binary packages from Glusterfs site installed glusterfs-server-3.0.0-1.x86_64 glusterfs-common-3.0.0-1.x86_64 glusterfs-client-3.0.0-1.x86_64 All works mainly ok, except every so often the IOZONE job just stops. The network IO drops to zero. This is always happens during either a read or re-read test. It happes just as the IOZONE read test starts. It doesnt happen every time and it may run for several hours without incident. This has happened 6 times on different test cases (thread/clients). Anyone else noticed this ? Perhaps I have done something wrong ? vol files attached - I know I dont need to distribute 1 remote vol - part of larger test with multiple vols. Attached sample outputs. 4 clients 4 files per client ran fine. 4 clients 8 files per client hung at re-read on 2nd pass of IOZONE. All jobs with 5 clients and 8 clients ran to completion.
