Assuming we have a server with 8 hdd, using raid5. After applying raid5 to the disk, solaris 11 will be install.
In my understanding, 8 hdd will represent 1disk(pls correct me if I'm wrong) and have one pool(rpool).
Using raid5 for 8hdd, could it be possible to have multiple pool? My objectives are:
1. Install OS in rpool
2. Install oracle software and create database in a separate pool.
The rpool can only be a mirror (raid1). You can have different pools for what you described. You just have to keep in mind that your raid decision is good for your performance and safety needs!

Hi flexi,
Firstly , we must know the your hardware system ?
Maybe we can determine best choice for your needs to that.
if your system x86 arch maybe you can try "LSI or other Logic Configuration Utility Console " which appears in the boot stages..
You assume 8 disks , but has your system contains these from local or san ?
if your all disks has local ( SAS / Sata .. ) , then what is the your critical data ? ( database )
all disks are at the same or size ?
Yes , Raid5 can be good choice or maybe not for avaliable disk space or security requirements.
That can change to your needs.
For exa : you want to create hard raid 5 vol with 6 disks at size 300 GB. ( security : with "1 disk" failure )
then your avaliable space ( n x size -1 x size ) = 6 x 300 - 1 x 300 ( for total parity size ) = 1500 GB
So at the reality , what is your systems for solaris ( oracle sparc / x86 / non-oracle x86 .. )
in Sparc systems LSI raid controllers does not support for raid 5
if you will be use zfs , then you can use software raid with zfs ( zpool )
For exa :
Now i can say what i do with 6 disk in my sparc hardware.
* 4 disk for RAID 1E ( security two disk in teory but may be "one disk" to controller !! )
-----------------------------------------------------------------------------------------
( * You can create similiar this volume with your 6 disks )
( boot prompt )
* create 4 disk with RAID 1E volume ( vol1 ) --> For your database pool
* After apply this , check volume :
---------------------------------------
* If raid volume is "inactive" state then starts
-> Now first Raid volume ( vol1 ) is Ready..
2-) The other 2 disk with RAID1 ( via the other Raid Controller port )
* Select the disk and create hard raid.
....
....
-> Now first Raid volume ( vol2 ) is Ready..
* Raid operations completed..
* I installed the Solaris OS on the this volume ( vol2 ) at the Disk Select Menu..
* when system is on :
vol2 ( in 2 disk with size 559 with RAID 1 ) ---> 2 X 559 /2 = 556 GB in OS
----------------------------------------------
note : my raid LSI controller(s) does not support other raid levels ( eg : raid5.. )
Hi all,
I am trying out Solaris 11.3
Realize the option of -p when using beadm that i can actually create another boot environment on another pool.

I have a single zpool with 3 2-way mirrors ( 3 x 2 way vdevs) it has a degraded disk in mirror-2, I know I can suffer a single drive failure, but looking at this how many drive failures can this suffer before it is no good?

Hi!
I would also like to know if I need first to create a pool before I can mirror my disks inside that pool.
My first disk is c7t0d0s0 and my second disk is c7t2d0s0 as seen in the figure below.
I would create a pool named rpool1 for this 2 disks.

I need to migrate an existing raidz pool to a new raidz pool with larger disks. I need the mount points and attributes to migrate as well. What is the best procedure to accomplish this. The current pool is 6x36GB disks 202GB capacity and I am migrating to 5x 72GB disks 340GB capacity. (2 Replies)
I created a pool the other day. I created a 10 gig files just for a test, then deleted it.
I proceeded to create a few files systems. But for some reason the pool shows 10% full, but the files systems are both at 1%? Both files systems share the same pool.
When I ls -al the pool I just... (6 Replies)

Hi;
Can someone please explain how do connections differ from threads? or a link to a good site about connection pooling and how threads are utilized by the OS.
