Description Gaurav Kumar Garg 2015-09-11 04:55:32 EDT
Description of problem:

Currently glusterd is crashing when enable/disable heal and i/o is in progress on the fuse mount.

refer bug 

for more details.

It seems to happen because of multi epoll thread between glusterd enable.

workaround is to make epoll thread to 1 and set ping-timeout to 0
Comment 3 SATHEESARAN 2015-09-15 11:31:44 EDT
Tested with glusterfs-3.7.1-15.el6rhs and glusterfs-3.7.1-15.el7rhgs

ping-timeout was set 0 and there is a new key named 'event-threads' available in glusterd vol file which is set to 1

Performed the basic glusterd sanity test cases as well.
All works well.
Marking this bug as VERIFIED
