Hi,
I am installing Oracle Linux 6.5. Normally when I do an install when the installer prompts for the type of install :
i. Use All Space
ii. Replace Existing Linux Systems
iii. Shrink Current Space
iv. Use Free Space
v. Create Custom Layout
I normally choose i. However this creates a number of logical volumes eg lv_root, lv_home etc.
This particular install if for an Oracle RAC I am setting up. So I will be using shared storage. In this case in the absence of an NAS/SAN, I will be configuring some of my internal disk space on node 1 as NFS ans using that as the shared storage for the cluster.
I have been advised that it is better to use Partitions with ASM, rather than the default Logical Volumes that option i. in the install above creates.
So I need to use option v. which brings up the partitioning tool during the Linux install.
My query is on how many partitions you can create on a physical disk ( for some reason I have in my mind the figure 4 ? )
It is my intention to create the following partitions -
/ ( root ) for the OS on this node
/home for the Oracle software on this node
/dev/shm ( for Swap ) on this node
/part1a
/part1b
/part2a
/part2b
/part3a
/part3b
I was going to use part1a through to part 3b as ASM candidate disks, creating a pair for each ASM Disk Group ( with Normal Redundancy )
i.e. /part1a and /part1b will be used for disk group +OCR
/part2a and part2b will be used for disk group +DATA
/part3a and part3b will be used for disk group +FRA
I am just not sure I can do this ?
I am not sure I can create all these as physical partitions on my internal disk.Can I create as many physical partitions as that on the same physical disk
any advice greatly appreciated,
thank
Jim
