Create Luster File system In Redhat Linux - Installation


To main the Luster file system, We have to Install the Following 6 rpm package in Client,Object Storage Server(OSS),Meta Data Server(MDS),
 To Install rpm package, use rpm -ivh
-i install
-v verose
-h hash
1)Even though we install the all package, e2fsprogs it is not install properly,
To check use rpm -qa command , So using rpm -Uvh update that package
2)Update the package
# rpm -Uvh e2fsprogs-1.41.10.sun2
Packages Are

Communcation Between Two Nodes,
For the communcation between the two node, We have to edit the in the modeprobe.conf file
1)we have to add entry in /etc/modprobe.conf
options lnet networks=tcp0(eth1)
#modprobe lnet [ update the driver]

List the Network
# lctl list_nids
IOC_LIBCFS_GET_NI error 100: Network is down

UP The Network
# lctl network up

LNET configured
# lctl list_nids
Just like update the MDS, OSS and CLIENT,

To Check For Pinging Whether It is Pinging Or Not
[root@mds ~]# lctl ping
These Are the Basic Luster Installation Step,

Note: In OSS and MDS we can create lustre file system using multiple
block device like /dev/sda1,/dev/sda2,/dev/sda3, but while mounting to the
client side we should mount with file system name. so it'll reflect as the
single partition from the multiple block device.
mount -t lustre [MDS node IP]:/[fsname]  [mount Directory]

Lustre File system command
#lctl Lustre control Interface Command
List the Network
Ping to the particular network.
#lfs Lustre File system Command.
ON quota,OFF quota,CHECK Quota,LIST Quota.
[lfs quotaon MP,lfs quotaoff MP,lfs quota /home ,lfs quotacheck MP, ] LFS set striping and get striping.[lfs getstripe file.
NOTE : MP = Mount Point
List the file system [lfs df -h,
#mkfs.lustre Is used to create file system

For Sample Luster Benchmark calculation
3.5 PB storage; 52 GB/s I/O throughput
131,072 processor cores
1.73 PB storage; 40GB/s I/O throughput
62,976 processor cores
340 TB Storage; 50GB/s I/O throughput
12,960 multi-core compute sockets
10.5PB storage; 240 GB/s I/O throughput goal
265,708 processor cores
