Re: [ceph-users] Ceph on XenServer

Hi Iban, you are running xen (just the software) not xenserver (ad hoc linux distribution). Xenserver is a linux distribution based on CentOS. You cannot recompile the kernel by your-own (... well, you can do, but it's not a good idea). And you should not install rpm by your-own (... but,

Re: [ceph-users] Ceph on XenServer

Hi Andrei, i don't think so. The future way to support Ceph in Xencenter is the kernel. Xencenter is based on centOS, and centOS is the downstream of RHE. This means that some day in the future the kernel of RHE will be already compiled to completly support RADOS. At that time having

Re: [ceph-users] Ceph on XenServer

Hi Max, Have you considered Proxmox at all? Nicely integrates with Ceph storage. I moved from Xenserver longtime ago and have no regrets. Thanks Brians On Sat, Feb 25, 2017 at 12:47 PM, Massimiliano Cuttini wrote: > Hi Iban, > > you are running xen (just the software) not

Re: [ceph-users] Ceph on XenServer

Hi Brian, never listen before. However seems nice and fully featured. The pity is that is based o KVM, which is as far as I know is a ligth hypervisor that is not able to isolate the virtual machine properly. Due to this is possible to frozen the hypervisor kernel from a guest virtual machine

Re: [ceph-users] Can Cloudstack really be HA when using CEPH?

I spoke with the cloud stack guys on IRC yesterday and the only risk is when libvirtd starts. Ceph is supported only with libvirt. Cloudstack can only pass one monitor to libvirt even though libvirt can use more. Libvirt uses that info when it boots, but after that it gets all the monitors from

Re: [ceph-users] Ceph on XenServer - Using RBDSR

Hi Max, I have a working Xenserver pool using Ceph RBD as a backend.. I got it working by using the RBDSR plugin here: https://github.com/mstarikov/rbdsr I don't have much time, but I just wanted to respond in case it's helpful... Here is how I got it working: On CEPH Set tunables to legacy #

Re: [ceph-users] Ceph on XenServer - Using RBDSR

Hi Mike, Have you considered creating SR which doesn't make one huge RBD volume and on top of it creates LVM but instead creates separate RBD volumes for each VDI? W dniu 25.02.2017 o 22:14, Mike Jacobacci pisze: Hi Max, I have a working Xenserver pool using Ceph RBD as a backend.. I got

Re: [ceph-users] Can Cloudstack really be HA when using CEPH?

You are correct again. I forgot that rrdns returns all address, just in different orders. So it doesn't matter that cloudstack can't pass libvirt multiple addresses even though libvirt can pass those to qemu and librados. On Feb 25, 2017 8:16 AM, "Wido den Hollander" wrote: > > >
