change cache option in existing disk offering

[Andrei Mikhailovsky <an...@arhont.com>]

Hello guys, 

I've got a bunch of existing vms which were created before the ACS cache option could be configured. The existing disk offerings show cache=none and I would like to change that. The GUI doesn't give me that option when I am editing the disk offering. 

Can I simply change the value in the database and stop/start each vm? Would this work? 

Many thanks 

Andrei

Hi Sanjeev,

this is not an option unfortunately as this will involve a great deal of manual work. There are hundreds of volumes in my small cloud setup.

What would happen if I just update the cache value in db and restart the vms? This should be much faster. 

Thanks

Hi Andrei,

It is not possible to modify the existing disk offering values. You can create another disk offering with cache option enabled and update the disks with the new offering.
