Hi Al, With XenServer, its always issue with moving bigger volumes. (operation just times out)
Here are the parameters that worked for me for bigger volume migrations in past. (You may want to tweak as per your env. may increase a bit. ) migratewait: 36000 storage.pool.max.waitseconds: 36000 wait:18000 *wait *is most critical of all . You need to change this in global config and this warrants management service restart. For the VHD chain read - https://support.citrix.com/article/CTX201296. Understand this. First, remove all the unnecessary snaps of disks etc. You need click on scan (from xencenter) after you remove snap etc. Good luck -- Makrand On Fri, Jul 20, 2018 at 1:12 PM, Alessandro Caviglione < c.alessan...@gmail.com> wrote: > Hi guys, > we need to move all the VM's disk from one storage to another. > Due to extremely slow performance of the source primary storage, migrate > VMs and DATA disks from cloudstack does not work because of timeout. > So, the alternative, is to move VHD files directly between the storage and > change Cloudstack DB... but I see that each VM has a loooong VHD chain and > CS DB point to the last one. > So... first question is: WHY?
