Red Hat Bugzilla – Bug 993692
client machine reboots when unmounting fuse mount point
Last modified: 2015-12-03 12:11:33 EST
Description of problem:
client machine is rebooting when we unmount a fuse mount after running dbench on the fuse mount. Refer to bug 990479 for failure in running dbench.
Version-Release number of selected component (if applicable):
glusterfs 126.96.36.199rhs built on Aug 4 2013 22:34:17
Steps to Reproduce:
1.Create a replicate volume ( 1 x 2 )
2.Set open-behind volume option to value "on"
3.Create 2 fuse mount and 1 nfs mount on a client machine.
4. Run "dbench -s -F -S -x --one-byte-write-fix --stat-check 10" on all the mount points simultaneously.
5. Once the dbench fails, stop dbench on other mount.
6. Execute: "rm -rf *" from mount point.
7. Execute: "dbench -s -F -S -x --one-byte-write-fix --stat-check 10" only on the mount point which failed to execute the dbench.
dbench fails to execute.
8. unmount one of the mount point (unmounted mount1)
Client node reboots.
client node shouldn't reboot
