Solaris

Assuming these disk are wholly dedicated to the mirror:

Code:

zpool create data mirror c0d0 c0d1

That's it. You have now a /data filesystem whose content are mirrored on d0 and d1. ZFS is dead simple when compared to alternate RAID solutions.

By the way, mirroring means each disk is a backup of the other one. There is no specific data disk and backup disk like you describe.

it should be strip and mirroring. What i trying to do is create a logical volume, it is contain 2 disk. whatever i did in disk A it will mirror to disk B. Disk B it is locate in slice 2 of logical volume and other slice is used by disk A.

Sorry I couldn't understand the above line.

As per my understanding all you need to do is create a metadb on both the disk. Take any of the unused slice , allocate space to that and create a 3 copy of meta db on the slice , some think like this

e.g. I am taking slice 7 for meta database

check the same with

For / ( root)


Likewise you can create volume for rest of the partition

Once done change the /etc/vfstab entry to point the partition towards the different volumes

Do the required entry into the /etc/system for rootdev

Also you need set the rootdisk/rootmirror

Reboot the system

( please verify the above steps I am just giving you kind of direction, I mean how you can plan the entire activity)

thank for you kindly info. I should finish installation solaris and partition it into 8 slice (0-7) Then afterward run above commands in single user mode?

What's happen to my disk volume, it is show c0d0 and c0d1. Without 't' then i still create a logical volume? (i am running x86 platform in virtualbox)

Could anyone make sure for me:

database replicates are always occupy a whole slice? (cannot make a filesystem on that slice ?)

always need a database slice for each mirror hard disk?

Webster5u: there is no reason to be concerned about the missing target on your disks. It is just they are (virtual) IDE disks, not SCSI/SATA ones.

What I was suggesting (adding two new disks and implement ZFS on them) is a very simple and straightforward solution. I'm disappointed to see you seem to prefer the complex way (SVM).

i haven't setup the metadb yet. I think my installed solaris is not configure well, it is hostname disappear, cannot run "raidctl" cmd and etc. it is not a good start point for me.

jlliagre, thank for your comment. it is really thank, i am currently assign into a project. i have to understand exactly how system administrator done to our company server. ZFS will be my alternative choice.

whatever, thank all of your.
