RAC Install on Linux Part2

Disk partitioning using fdisk:


a. create partition for storing RAC software:

Add Partition for storing RAC and mount it

Mkdir /u02

[root@node1 /]# mkfs -t ext3 /dev/sdb1
mke2fs 1.35 (28-Feb-2004)
Filesystem label=
OS type: Linux
Block size=4096 (log=2)
Fragment size=4096 (log=2)
1572864 inodes, 3144715 blocks
157235 blocks (5.00%) reserved for the super user
First data block=0
Maximum filesystem blocks=3221225472
96 block groups
32768 blocks per group, 32768 fragments per group
16384 inodes per group
Superblock backups stored on blocks:
32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632, 2654208

Writing inode tables: done
Creating journal (8192 blocks): done
Writing superblocks and filesystem accounting information: done

This filesystem will be automatically checked every 30 mounts or
180 days, whichever comes first. Use tune2fs -c or -i to override.
[root@node1 /]#

Mount it and add it in /etc/fstab

[root@node1 /]# mount -t ext3 /dev/sdb1 /u02
[root@node1 /]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00
9.0G 6.9G 1.7G 81% /
/dev/sda1 99M 14M 81M 15% /boot
none 506M 0 506M 0% /dev/shm
/dev/mapper/VolGroup00-LogVol02
9.9G 55M 9.3G 1% /u01
/dev/sdb1 12G 63M 12G 1% /u02
[root@node1 /]#

/dev/sdb1 /u02 ext3 defaults 1 1  /etc/fstab – to boot at startup



b. create partiotions for OCR, VD and ASM files.
[root@node1 ~]# fdisk /dev/sdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel. Changes will remain in memory only,
until you decide to write them. After that, of course, the previous
content won't be recoverable.

Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)

[root@node1 ~]#

Do this similarly for all the partitions


[root@node1 ~]# fdisk -l

9. Download OCFS2 and ASM libraries from oracle site
http://oss.oracle.com/projects/ocfs2/files/RedHat/
—This should be based on your kernel and OS version


Make sure you have shared the folders from vmware to access them




My kernel version is:
[root@node1 /]# uname -r
2.6.9-78.ELsmp
