Hello,

I am installing Lustre 1.87 on RHEL 5.8 and having issue while configuring OST on one of the node. These are the steps I am performing reading through manual, please reply how to proceed further. Please let me know if you find any issue with these steps:

1. I have 2 RHEL 5.8 hosts, one for MGS and another one for OSS

2. Configured Static IP address on both the hosts

3. Disabled SELINUX in /etc/selinux/config file

4. Provision 1 raw disk each to both the systems for MDT and OST, did not created any partition on them

5. Installed lustre 1.87 RPM packages on both the machines in the given order

o kernel-2.6.18-194.17.1.el5_lustre.1.8.7.x86_64.rpm

o lustre-ldiskfs-3.1.6-2.6.18_194.17.1.el5_lustre.1.8.7.x86_64.rpm

o lustre-modules-1.8.7-2.6.18_194.17.1.el5_lustre.1.8.7.x86_64.rpm

o lustre-1.8.7-2.6.18_194.17.1.el5_lustre.1.8.7.x86_64.rpm

o e2fsprogs-1.42.ora1-0redhat.rhel5.x86_64.rpm

o e2fsprogs-devel-1.42.ora1-0redhat.rhel5.x86_64.rpm

o Am I missing any package or order?

6. Modified /etc/modprobe.conf to have : options lnet networks=tcp0(eth0)

7. Rebooted both the machines

8. Disabled iptables and ip6tables

9. On machine 1 for MDS / MGS Server, successfully executed following command to create MGS/MDT file system

a. mkfs.lustre –fsname=lustre –mgs –mdt /dev/sdb

b. mount –t lustre /dev/sdb /mnt

10. On machine 2 executed following command, but it fails with the error as I mentioned before:

a. mkfs.lustre –fsname=lustre –ost –mgsnode=10.243.107.39@tcp0 /dev/sdb

i. Fails with the error :

1. mkfs.lustre: Can't make configs dir /tmp/mntRiWwg6/CONFIGS: Input/output error

2. mkfs.lustre FATAL: failed to write local files

3. mkfs.lustre: exiting with -1 (Unknown error 18446744073709551615)

b. I tried the same command with the machine 1 as well to have MGS and OSS on the same machine, but still have the same issue.

Please let me know are these the similar approach you take or something else I need to do. Next thing I am planning is to download and compile the sources of Lustre 2.3 and perform the same exercise on RHEL 6.3. Can you please let me know what all source rpms I need to download and build?

Thanks.
