+1: you almost certainly have SELinux enabled. The formatting of the file system will fail
with this error when SELinux is configured. For example, on a test system I have set up a
quick experiment to replicate your problem by setting SELinux to "enforcing":

[root@m64-1 ~]# cat /etc/selinux/config

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of these two values:
#     targeted - Targeted processes are protected,
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted

[root@m64-1 ~]# mkfs.lustre --reformat --mgs /dev/sdb

When SELinux is disabled, the file system will format without issue. You will have to edit
the appropriate configuration (on RHEL/CentOS: /etc/selinux/config) and reboot the system
in order for the change to take effect.

Malcolm.

Upanshu,

The error message you're getting is what's expected if you still have SELinux
enabled on that system.  I don't think you need to worry about lctl or the LNET
settings right now - The mkfs.lustre is failing because it can't make the temporary
directory.

I'd make sure selinux is set to disabled in /etc/selinux/config.
The line which starts 'selinux=' should read 'disabled'.

You can check whether or not that setting has taken effect with:
getenforce

I'd suggest making sure of that config file change and restarting the system, then try
your format command again.
