Description Vijaikumar Mallikarjuna 2015-05-27 09:22:59 UTC 
Description of problem:


With NFS mount, brick process hangs with too many parallel IOs.
Below testcase hangs:

1) Create a Disperse volume with 3 bricks
2) From NFS mount point execute below command
   dd if=/dev/zero of=/file1 bs=1020M count=1

NFS client splits 1024M block size to multiple chunks of size 256k and does parallel writes
Comment 1 Vijaikumar Mallikarjuna 2015-05-27 10:49:26 UTC 
Issue happens even without quota and with single brick.
This could be an issue with NFS client with larger block-size. Closing the bug for now
