Lustre 1.6 Operations Manual

Because megan and oscar match the first rule, LNET uses eth0 and eth1 for tcp0 on
those machines. Although they also match the second rule, it is the first matching
rule for a particular network that is used. The servers also match the (only) Elan
rule. The [2-8/2] format matches the range 2-8 stepping by 2; that is 2,4,6,8. For
example, clients at 132.6.3.5 would not find a matching Elan network.
7.1.2 Start Servers
For the combined MGS/MDT with TCP network, run:
$ mkfs.lustre --fsname spfs --mdt --mgs /dev/sda
$ mkdir -p /mnt/test/mdt
$ mount -t lustre /dev/sda /mnt/test/mdt
- OR -
For the MGS on the separate node with TCP network, run:
$ mkfs.lustre --mgs /dev/sda
$ mkdir -p /mnt/mgs
$ mount -t lustre /dev/sda /mnt/mgs
For starting the MDT on node mds16 with MGS on node mgs16, run:
$ mkfs.lustre --fsname=spfs --mdt --mgsnode=mgs16@tcp0 /dev/sda
$ mkdir -p /mnt/test/mdt
$ mount -t lustre /dev/sda2 /mnt/test/mdt
For starting the OST on TCP-based network, run:
$ mkfs.lustre --fsname spfs --ost --mgsnode=mgs16@tcp0 /dev/sda$
$ mkdir -p /mnt/test/ost0
$ mount -t lustre /dev/sda /mnt/test/ost0
