[lustre-discuss] Slow mount on clients

[Andrew Elwell]

Hi Folks,

One of our (recently built) 2.10.x filesystems is slow to mount on
clients (~20 seconds) whereas the others are nigh on instantaneous.

We saw this before with a 2.7 filesystem that went away after doing
<something unknown / filesystem upgrade> but we've no idea what.

Nothing obvious in the logs.

Does anyone have suggestions for what causes this, and how to make it
faster? It's annoying me as "something" isn't right but I can't
identify what.


Many thanks

Andrew
