[Lustre-discuss] Client unable to connect after reboot: Unable to process log 108

[David Noriega]

I've begun to notice this behavor in my clients. Not sure whats going
on, but when a client reboots, its unable to mount lustre. I have to
use 'lctrl ping' to ping any of the lustre nodes before I'm able to
mount the lustre filesystem. Any ideas?
