Extend a filesystem on ServiceGuard CFS cluster.

Hi everybody, I have setup a ServiceGuard CFS cluster for Oracle RAC 10G one year ago. Now I'm getting out of space for the db and I need to grow the filesystem, now I've assigned three new LUNs for both nodes of the cluster, but I don't know how to extend the diskgroup, then the logical volumes and finally the filesystem.

Any suggestion??

Regards

David,

If you're unure how to do this, remember that Veritas provide a GUI for their tools. Just run

vea

and you should be able to point & click your way through it...

You'll need a Xwindows software etc. to do this.

Or if you have a support contract you should be able to see this RC doc:

Re: Extend a filesystem on ServiceGuard CFS cluster.

Thnks Duncan, I'll try both options maybe next weekend, just for in case that I need a reboot, cause I've had some troubles adding LUNs to the cluster before.

Thanks!!

Re: Extend a filesystem on ServiceGuard CFS cluster.

1. find the master node by eecuting the below command since u sould execute CFS commands on master node.
#vxdctl -c mode
2. find the newly added disk
#vxdisk list
If ur not able to find the newly added disk do the following steps
#vxdisk scandisks
#vxdisk list
Still the problem persists, carry out the following steps, this won't make any harm on ur running system.
#mv /etc/vx/disk.info n/etc/vx/disk.info.old
#vxconfigd -m -k enable

3. Initialize new disks
#vxdisksetup -i cxtxdx
4. Add new disks to Disk Group
#vxdg -g adddisk disk1 disk2 disk3 ....
5. Verif the DG
#vxdisk list
6. Find the free space
#vxassist -g -p maxsize
OR
#vxdg -g cfsdg8 free
7. Extend the Volume
#vxassist -g growby
#
8. Find the current total size
# vxprint -g -pl

9. Extend the file system
#fsadm -F vxfs -b

Eg: vxdctl -c mode
vxdisk list
vxdg -g cfsdg8 adddisk c3t7d6 c3t7d7 c3t8d0 c3t8d1
vxdisk list
vxdg -g cfsdg8 free
vxassist -g cfsdg8 growby lvol1 102062592
vxprint -g cfsdg8 -pl
bdf
fsadm -F vxfs -b 202062592k /u09
