Re: [Openstack] [Cinder] Help needed recovering cinder volumes

It seems your LVM thin pool metadata is corrupt. I'm not familiar with this issue and can't guide you on how to fix it. Although this could have been caused by cinder, it's an LVM issue and if you don't get more answers here you may try some Linux related forum. On a quick search on "lvm2 thinpool

Re: [Openstack] nova live migration setup

Best practice is to use shared storage and then the "copy" is really only the active memory. A few changes came about in about the newton? timeframe that allows for some memory convergence. Take a look at the nova release notes from that time forward and you should see reference to the change(s).

This cluster is still predeployment so some information isn't locked in place but currently: We are using libvirt/kvm for the hypervisor. The network is 2 primary VLANs on a 10GiB bond (one VLAN for provider, one for Management & Storage). Network load is currently very low, but I can expect it

Re: [Openstack] Unable to start devstack@n-cpu.service

In my experience, a DevStack cloned from the master branch (which is the default) may occasionally run into inconsistencies such as incompatible library versions. Try a stable branch e.g. git clone ... –b stable/queens. Or just clone the master again later. Your local.conf may also be at the

Yes, I agree, it does seem to be an LVM issue rather than cinder. I will pursue that course. Thank you all for your help, it is fantastic having a support mailing list like this! FV > On Mar 21, 2018, at 4:45 AM, Vagner Farias wrote: > > It seems your LVM thin pool metadata is corrupt. I'm n
