[Gluster-users] Handling a fuse mount with a failed gluster node

[Grant Ridder]

Hi,

I am testing out several failure scenarios with GlusterFS.  I have a 3 node
replicated gluster that i am testing with.

One test i am having trouble solving is when a host dies.  (i.e. as if
someone pulled the power cord out).
- Firewall off a host from the rest of the cluster
- Test time it takes for a fuse mount to respond once the iptables rule is
added

With the default settings, the mount hangs for 39 seconds.  If i
change ping-timeout to 5 then the mount only hangs for 9.3 seconds.  Is
there anyway to eliminate or get the hang time to a negligible value (less
than 1 second)?

I have not seem much about handling GlusterFS failure scenarios with my
Googling around.

Several blog posts i have looked at:

https://joejulian.name/blog/keeping-your-vms-from-going-read-only-when-encountering-a-ping-timeout-in-glusterfs/

Thanks,
Grant
