Hi all,
As we will soon be replacing our lustre servers, I am currently trying
to setup a test filesystem to practice the process of setting it all up.
I've installed Centos 7.2 on a couple of old server nodes to use as my
test mds/mdt and oss.
I have been following the setup guide from :
http://doc.lustre.org/lustre_manual.pdf
I have the server modules installed with yum and have started the lnet
by loading the lnet module with modprobe.
yum --nogpgcheck install kernel-3.10.0-327.3.1.el7_lustre.x86_64.rpm \
lustre-2.8.0-3.10.0_327.3.1.el7_lustre.x86_64.x86_64.rpm \
lustre-modules-2.8.0-3.10.0_327.3.1.el7_lustre.x86_64.x86_64.rpm \
lustre-osd-zfs-mount-2.8.0-3.10.0_327.3.1.el7_lustre.x86_64.x86_64.rpm \
lustre-osd-zfs-2.8.0-3.10.0_327.3.1.el7_lustre.x86_64.x86_64.rpm \
lustre-iokit-2.8.0-3.10.0_327.3.1.el7_lustre.x86_64.x86_64.rpm
modprobe lnet
The documentation tells me to use lnetctl to configure then network,
this command does not exist, though oddly it's manual page does! This
probably doesn't matter (in the test setup) as I only have one active
network interface on the two machines.
I want to use zfs as my backing filesystem so have setup a zfs pool on
two of my disks :
zpool status
pool: testpool
state: ONLINE
scan: scrub repaired 0 in 0h0m with 0 errors on Mon Sep 12 10:43:07 2016
config:
NAME STATE READ WRITE CKSUM
testpool ONLINE 0 0 0
mirror-0 ONLINE 0 0 0
driveb ONLINE 0 0 0
drivec ONLINE 0 0 0
errors: No known data errors
However I'm not sure what to use as the block device to be fed to
mkfs.lustre ? as the documentation seems a little sketchy regarding zfs.
Can anyone assist please?
Cheers.
Phill.
