Before running auster, which tries to launch a lot of tests, start with just a plain mount to see if that is working:

master.sh:
> MOUNT=/mnt/lustre
> MOUNT2=/mnt/master2

This is a bit odd for tests, which normally have e.g. /mnt/master and /mnt/master2, but I'm
not sure i there will be a problem or not.

### assume modules/utils are built
### modules/utils are installed or you are running out of the build directory
### ssh to the MDS and OSS nodes works without a password
### if you are not using @tcp0 for LNet, /etc/modprobe.d/lnet.conf is correct

all# modprobe ptlrpc		### on client and OSS and MDS to start LNet
x8602# lctl ping x86ohpc	### should print NID(s) of x860hpc
x8602# lctl ping x8601		### should print NID(s) of x8601
x8602# export NAME=master	### get config from lustre/tests/cfg/master.sh
x8602# sh llmount.sh		### should format x86ohpc:/dev/sda2 and x8601:/dev/sda2
x8602# lfs df			### should show master-MDT0000 and master-OST0000

Cheers, Andreas
