CLuster File System (CFS) on LDOM Setup
Created: 27 Aug 2014 | 3 comments
Hi Experts
I need a quick help on below requirement.
I am planning two LDOM's (VM SPARC Server) on two different physical Solaris Systems. Both LDOM's are running two instance of application for scale up architectur (means x instance of Application will run on one LDOM and remianing y instance will on second LDOM). But application require's one of file system to be shared across both LDOM's for application requirement. I tried shared disk group on physical controller system and shared volume to both LDOM's but while mounting inside LDOM's, it do not allow me to mount both at same time. Can anyone help to finalize this plan.

Hi Rajendra,
couple of questions
1. Do you have CVM/CFS installed already on LDOMs & cluster is formed ?
2. What is the OS version you are using ?
3. When you are saying it is not allowing to mount, what exact commands you have run & what is the error ?

Dear Gaurav
This is Solaris 10 system with Update 11 and VCS 6.0.1.
I have installed CVM/CFS only on Controlelr Domain. Not inside LDOM yet. While I created a shared DG and volume (created vxfs FS too) on physical domains and assigned volume to LDOM inside each Host. Inside domain, on one node I mounted using plain "mount -F vxfs /dev/c1d0s0 /tibco". While I tried to mount this on other node, it asked me to ran fsck. When I unmounted from first node, then I was able to mount inside another LDOM without any trouble. I was not able to mount FS inside both LDOM at the same time.
I had installed only VxVM/VxFS inside both LDOM.
I feel CVM/CFS should also be installed inside both LDOM but guide mentioned in my question and respective diagram mention only VxFS inside LDOM.
If I need to install CVM/CFS inside both LDOM, does it mean to setup a 2 node cluster inside both LDOM separately. In that case, should I assign VxVM Volume to LDOM (from shared DG) or just LUN can be assigned to LDOM's? If I assign VxVM volume, in that case it will be two layer of VxVM as inside LDOM also a VxVM DG should be created or just plain disk can be mounted?
Appreciate your help.....
