That's not a bad position. I have concerns with what I'm proposing, so a hypervisor migration may actually bring less risk than a storage abomination. On Dec 9, 2017 7:09 PM, "Donny Davis" wrote: > What I am getting at is that instead of sinking a bunch of time into this > bandaid, why not sink

What I am getting at is that instead of sinking a bunch of time into this bandaid, why not sink that time into a hypervisor migration. Seems well timed if you ask me. There are even tools to make that migration easier http://libguestfs.org/virt-v2v.1.html You should ultimately move your hypervis

We have over 150 VMs running in vmware. We also have 2PB of Ceph for filesystem. With our vmware storage aging and not providing the IOPs we need, we are considering and hoping to use ceph. Ultimately, yes we will move to KVM, but in the short term, we probably need to stay on VMware. On Dec 9, 20

Just curious but why not just use a hypervisor with rbd support? Are there VMware specific features you are reliant on? On Fri, Dec 8, 2017 at 4:08 PM Brady Deetz wrote: > I'm testing using RBD as VMWare datastores. I'm currently testing with > krbd+LVM on a tgt target hosted on a hypervisor. >

Master is the current development version available from git. You have to compile it yourself to use that version. It's what the developers are currently working on, but hasn't been merged into a release yet. On Sat, Dec 9, 2017, 12:33 PM Sameer S wrote: > Hi David, > > What version does "master

To get specific versions of the ceph documentation you change the version in the URL to yours. If you see giant, kraken, matter, Luminous, Hammer, Jewel, etc in the URL right after docs then change it to the one you want. The following URL is for master. You would replace the master after docs for

Hi, 1. Is there a clear procedure documented for removing a failed ceph-node ? I have read and performed removing ODSs successfully, but are there commands that can be used to remove the node itself ? 2. On the ceph documentation website, how can I find Jewel, Kraken or Luminous specific docs ?
