Hi, you could also do this offline using libguestfs tools:
- Find the path to the disk using virsh -r dumpxml HostedEngine - Stop the vm using hosted-engine --vm-shutdown - and then use guestfish tool to edit the filesystem: guestfish --rw -a disk.img Best regards Martin Sivak On Tue, Oct 31, 2017 at 9:00 AM, Simone Tiraboschi <[email protected]> wrote: > Hi, > the simplest approach is: > > hosted-engine --set-maintenance --mode=global > hosted-engine --vm-shutdown > # wait for it > hosted-engine --vm-start-paused > hosted-engine --add-console-password > # open a vnc or spice console pointing to the VM > # when ready > virsh -c qemu://$(hostname)/system resume HostedEngine > # quickly stop the boot process from the vnc or spice console > # force root password as for a regular el7 system > # shutdown the engine VM > hosted-engine --set-maintenance --mode=none > > > > On Sat, Oct 28, 2017 at 11:25 PM, Chas Ecomm <[email protected]> wrote: >> >> TIA for any guidance you can give me here, I’m in a bit of a pickle and >> have spent many hours reading many posts and blogs that don’t seem to get me >> where I need to be, and despite my gut feeling that someone has had to have >> dealt with this somewhere else, my google-fu is failing me in finding anyone >> who has dealt with this particular problem. >> >> >> >> My issue: >> >> >> >> I’ve inherited a 4.1 hosted-engine setup.
