Volume info : ============ [root@jay tmp]# gluster v i sample Volume Name: sample Type: Distribute Volume ID: 1895ec09-a451-4182-acd6-b258519c8c8e Status: Started Number of Bricks: 2 Transport-type: tcp Bricks: Brick1: 10.70.34.86:/BRICK1/b1 Brick2: 10.70.34.87:/BRICK1/b2 ===================================================================== sosreports at : http://rhsqe-repo.lab.eng.blr.redhat.com/bugs_necessary_info/990897/ |
Description of problem: ======================== I/O error on calculating are equal check sum on mount point , while trying to create files which are greater than the brick size Version-Release number of selected component (if applicable): ============================================================= 3.4.0.14rhs-1.el6rhs.x86_64 How reproducible: ================= always Steps to Reproduce: =================== 1.Create a distribute volume with 2 bricks (each brick is 1GB in size) 2.Fuse mount the volume and create files which are greater than the brick size for i in {1..500} ; do dd if=/dev/urandom of=f"$i" bs=10M count=1; done Files are created and after some time , we get 'No Space left on device' 3.[root@RHEL6 sample]# du -sh 1.9G 4. Are equal check sum on the mount point fails with short read : /opt/qa/tools/arequal-checksum /mnt/sample/ md5sum: /mnt/sample/f164: No such file or directory /mnt/sample/f164: short read ftw (/mnt/sample/) returned -1 (Success), terminating Are equal check sum fails with short read for /f164 . As per our understanding , f164 was being created when the first brick was full and it creates a link file on the other brick for creation of file f164 and then continues with the creation of other files and so are equal fails with short read .
