Great, this my first time, so just for confirmation I'll the following steps: 1- add storage tag to current disk offerings to force craeting new volumes on new Primary storage from now on You need to create offering disk/compute to use the storage tags so that deployment happens using that storage only. If that's the only storage available then CS will deploy in that storage only. 2- enable maintenance mode on old primary storage and it will shutdown all instances which has volumes on that. If systemvm's are running on the storage, CS will migrate them to possible deployment storage. 3- move volumes to New primary storage manually Once you have added new primary storage, from UI you can migrate the disks to any storage. 4- restart netword on each account (clean-up is marked) to recreate VR on new primary storage. Yes. It will recreate VR's Are they the correct steps? ----- Original Message ----- From: "Rajesh Battala" <rajesh.batt...@citrix.com> To: <users@cloudstack.apache.org> Sent: Sunday, April 27, 2014 9:28 AM Subject: RE: How to migrate volumes of Virtual routers Process I had mentioned will work for all system vms.

How to migrate their volumes to second primary storage? ----- Original Message ----- From: "Rajesh Battala" <rajesh.batt...@citrix.com> To: <users@cloudstack.apache.org> Sent: Saturday, April 26, 2014 8:20 PM Subject: RE: How to migrate volumes of Virtual routers Add the new primary store. Enable Maintenance mode on the old primary store. CS will take care of migrating the VM's running the old store to the new one. Once the migrations are complete CS will report the status. Then remove the old store. Yes You can use tags to force CS to pick the tagged resources.

This is the linux behavior nothing to do with the cloudstack. Please restart the VR to make the disk writable. -Sanjeev -----Original Message----- From: Amir Abbasi [mailto:abb...@tebyanidc.ir] Sent: Wednesday, April 23, 2014 10:58 AM To: users@cloudstack.apache.org Subject: How to migrate volumes of Virtual routers Hi, I've assigned two primary storages. All virtual routers have been created on Primary-Storage1 but sometimes I face "Read-only file system" on some VR instances. I found no option to migrate their volumes. I have cloudstack 3.0.
