Hi can you share the 'gluster volume info' output ? I tried with stripe of 3 bricks, and things worked without any errors for the same Iozone command. (it was not in xen server though). Can you also share the glusterfs client log (located @ $prefix/var/log/glusterfs/<mountpoint>.log), which will help in cornering the issue.

Can you confirm that this stripe volume also is created by 3.1.x version? -Amar Sorry About that , I simply moved on to other volume configurations in the meanwhile :-) The Volume in question was infact a stripe volume created by glusterFS 3.1.1 Hi Idan, Let us know if this issue is still 'critical' for you, and does it gets reproduced in 3.1.2 or later versions. I am marking it as 'normal' for two things. 1. stripe being not recommended translator 2. we couldn't reproduce this issue. I ran your tests on a stripe config, and it works fine for me on the latest git (master). Please re-open the bug if it re-occurs. |
