I would strongly suggest make -j something for parallelism, unless you want to 
have time to go out for your coffee.

You can rebuild 2.8 against MOFED. 1) Install MOFED version of choice. 2) Pull 
down the 2.8 Lustre source and configure with 
'--with-o2ib=/usr/src/ofa_kernel/default'. 3) `make rpms` 4) Install. 5) Profit.

I'm assuming the issue is that lustre 2.8 is built using the standard Centos 
7.2 infiniband drivers.

I can't move to Centos 7.3, at this time.  Is there any way to get 2.8 up & 
running w. mofed without rebuilding lustre rpms?

If I have to rebuild, it'd probably be easier to go to 2.10 (and zfs 0.7.1). Is 
that a correct assumption?
Or will the 2.10 rpms work on Centps 7.2?

thanks,

John,

You can rebuild 2.8 against MOFED. 1) Install MOFED version of choice. 2)
Pull down the 2.8 Lustre source and configure with
'--with-o2ib=/usr/src/ofa_kernel/default'. 3) `make rpms` 4) Install. 5)
Profit.

[lustre-discuss] Best way to run serverside 2.8 w. MOFED 4.1 on Centos 7.2

[john casu]

I have an existing 2.8 install that broke when we added MOFED into the mix.

Nothing I do wrt installing 2.8 rpms works to fix this, and I get a couple of 
missing symbole, when I install lustre-modules:
depmod: WARNING: /lib/modules/3.10.0-327.3.1.el7_lustre.x86_64/extra/kernel/net/lustre/ko2iblnd.ko needs unknown symbol 
ib_query_device

depmod: WARNING: 
/lib/modules/3.10.0-327.3.1.el7_lustre.x86_64/extra/kernel/net/lustre/ko2iblnd.ko
 needs unknown symbol ib_alloc_pd

I'm assuming the issue is that lustre 2.8 is built using the standard Centos 
7.2 infiniband drivers.

I can't move to Centos 7.3, at this time.  Is there any way to get 2.8 up & 
running w. mofed without rebuilding lustre rpms?

If I have to rebuild, it'd probably be easier to go to 2.10 (and zfs 0.7.1). Is 
that a correct assumption?
Or will the 2.10 rpms work on Centps 7.2?
