Ahh Packstack does not have pcs.. that’s only OOO. And what does your /var/log/cinder/cinder-volume say? Is this all in one? Split? Looks like your cinder is having some issues.. check out targetcli here is a ref page https://www.certdepot.net/rhel7-configure-iscsi-target-initiator-persistent

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

Will "lvchange -a y lvname" activate it? If not, considering that you're using Pike on Centos, there's a chance you may be using the cinder-volumes backed by a loopback file. I guess both packstack & tripleo will configure this by default if you don't change the configuration. At least tripleo wo

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

What kind of device is backing your LVM PVs? Is it a disk partition or a loopback device? If it's the latter, is it activated? What does "pvs" returns? If vgscan won't show any logical volumes, you're probably looking at the wrong device or the LVs were removed. If this happened, you may be able

Hello everyone, I am in need of help with my Cinder volumes which have all become unavailable. Is there anyone who would be willing to log in to my system and have a look? My cinder volumes are listed as "NOT available" and my attempts to mount them have been in vain. I have tried: vgchange -a

Hi Is there a way to check heat templates. At the moment I run one and it errors at runtime when, for example an something expects a string but gets a list. For example in this case of an OS::Heat::SoftwareConfig resource, the config attribute below expects a string, which is why str_replace works
