Subject Switching Snitch
Date Thu, 23 Aug 2018 17:08:42 GMT
Hello,

I am currently running a 3.11.2 cluster in SimpleSnitch hence the
datacenter is datacenter1 and rack is rack1 for all nodes on AWS. I want to
switch to GPFS by changing the rack name to the availability-zone name and
datacenter name to region name.

When I try to restart individual nodes by changing those values, it failed
to start throwing the error about dc and rack name mismatch but gives me an
option to set ignore_dc and ignore_rack to true to bypass it.

I am not sure if it is safe to set those two flags to true and if there is
any drawback now or in future when i add a new datacenter to the cluster. I
went through the documentation on Switching Snitches but didn't get much
explanation.

Regards,
Pradeep
