Yes for sure check the logs. At times with my 1.87 after starting the clients
before the MDS it takes some time for the reconnect. Hope you resolved by
reading logs. Otherwise waiting for a reconnect is an option but I usually
reboot the clients and know after the boot screen if they mounted or not within
10 seconds without having to look.

Inactive OST means that the MDS cannot contact the OST for some reason (OST is
not running, firewall rules, etc). You need to check console logs on MDS or OSS
to see why.
