I don't know the problem here, but you might want to look for
connectivity issues from the client to the OSS(s) that house those
two missing OSTs. I would image the lustre.log would show such
errors in bulk. I've seen where an IB subnet manager gets in a
weird state
G'Day all,
I have an odd situation where 1 compute node, mounts /home and /lustre but
only half the OST's are present, while all the other nodes are fine not
sure where to start on this one?
Good node:
[root@n02 ~]# lfs df

There was a mix of small vs medium size. I reread the "Sizing MDT"
section in the manual and see my error. That section should be in big
bold letters at the very beginning... :)

As long as the inode-discussion is up, two questions; what exactly is
stored in the inode (how big should i make them) I've read the manual
about this and it doesnt really say except the notation about
stripes/osts.
Is there a "proper" way of "moving" or recreating the mdt-filesystem
to hold more
do you have many small files?

I have a small lustre test cluster with eight OST's running. The
servers were shut off over the weekend, upon turning them back on and
trying to startup lustre I seem to have lost my OST's.
