What is your version of e2fsprogs?
What is your command line to format your raid?

Our lustre 1.8.4 system sits primarily on subnet A. However, we also
have a small number of clients that sit on subnet B. In setting up the
subnet B clients, we provided lnet router machines that have addresses
on both subnet A and on subnet B, the MGS machine has addresses on both
subnet A a
I am having the following issue:
trying to create an ext4 lustre filesystem attached to an OSS.
the disks being used are exported from an external disk enclosure.

I am able to format such an array with normal ext4, mount a f

While this "runs", it is definitely not correct. The problem is that the
client will
In our lab, we've never had a problem with simply having 1 MGS per filesystem.
Mountpoints will be unique for all of them, but functionally it works just fine.

Hi all,
we have gotten new MDS hardware, and I've got two questions:
What are the recommendations for the RAID configuration and formatting
options?
I was following the recent discussion about these aspects on an OST:
