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<mailto:-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.
