At the time this happened, I was also ssh'ed into the host, and was doing some rpm querry commands. I had just run rpm -qa |grep glusterfs (to verify what version was actually installed), and that command took almost 2 minutes to return! Normally it takes less than 2 seconds. That is all pure local SSD IO, too.... I'm no expert, but its my understanding that anytime a software causes these kinds of issues, its a serious bug in the software, even if its mis-handled exceptions. Is this correct? --Jim On Tue, May 29, 2018 at 3:01 PM, Jim Kusznir <jim(a)palousetech.com&gt; wrote: > I think this is the profile information for one of the volumes that lives > on the SSDs and is
