As a follow up, our MDS was locking up under load so I went ahead and tried
it. It seemed that some directories were getting bounced around the MDS
servers and load would transition from one to the other. Initially my guess
was that some of these old clients were sending all requests to one MDS

If there was a network blip and a client was having trouble reconnecting,
do you think reducing the ranks to 1 would allow them to connect? At which
point the ranks could be increased again.
Or is it a matter of the client kernel panicking so any kind of
reconnection won't work?
Thanks
Thanks guys. We are so close to the edge that we may just take that chance,
usually the only reason an active client has to reconnect is because we
have to bounce the MDS because it's overwhelmed.

I've seen issues with clients reconnects on older kernels, yeah. They
sometimes get stuck after a network failure
