Re: Ovirt + Gluster : How do I gain access to the file systems of the VMs

Hi Guys, I've an answer... Here's how I did it... First, I needed kpartx ... so #apt-get install kpartx Then setup a loopback device for the raw hdd image #losetup /dev/loop4 [IMAGE FILE] #kpartx -a /dev/loop4 This allowed me to mount the various partitions included in the VM. There you can modify the configs, make backups etc. Thanks, Hanson On 06/19/2018 09:31 AM, Hanson Turner wrote:
Hi Sahina,
Thanks for your reply, I can copy the files off without issue. Using either a remote mount gluster, or just use the node and scp the files to where I want them.
I was asking how to/do I mount the VM's disk in a way to be able to pull/modify files that are on the HDD of the VM.
Thanks,
Hason

Hi Guys,
My engine has corrupted, and while waiting for help, I'd like to see if I can pull some data off the VM's to re purpose back onto dedicated hardware.
Our setup is/was a gluster based storage system for VM's. The gluster data storage I'm assuming is okay, I think the hosted engine is hosed, and needs restored, but that's another thread.
I can copy the raw disk file off of the gluster data domain. What's the best way to mount it short of importing it into another gluster domain?
With vmware, we can grab the disk file and move it from server to server without issue. You can mount and explore contents with workstation.
If you want to copy the image file. you can mount the gluster volume and copy it. using mount -t glusterfs <gluster-server>:/<volumename> <path-to-mount>
What do we have available to us for ovirt?
Thanks,
