<br>
I've been trying to create a small cluster of virtual machines to get some experience of working with Lustre. I have a dedicated mgs/mds/mdt node running a kernel from<br>
2.6.32-279.2.1.el6_lustre.1.8.8_x1 Lustre official package. I have installed necessary Lustre rpms (lustre-ldiskfs, lustre-modules, lustre) corresponding that kernel, which along with the kernel were downloaded from 1.8.8 branch folder at <a href="http://downloads.lustre.org" target="_blank">downloads.lustre.org</a>. Problem is, when I try to execute mkfs.lustre command from the manual (mkfs.lustre --mdt --mgs --fsname=SANDBOX /dev/sdb) having, as seen, only changed device name and fs name, it fails in the following manner:<br>
<br>
[root@test-lustre-mds1 ~]# uname -a<br>

<br>
What should I do to debug this issue?<br>
<br>
Thanks,<br>
