In CentOS 7 the cinder (and instance creation along with it) service fails to start due to insufficient permission to create /var/lock/cinder directory

[Michal Adamczyk]

The fix - use following path and the cinder service will start normally without changing permissions to /run/lock directory:

[oslo_concurrency]

lock_path = /var/lib/cinder/tmp

@matt, IIRC you did some work on the temp file path in the install guide before. Can you confirm?

Bernd Bausch noted in the duiplicate bug:

On my Centos 7 system (CentOS Linux release 7.1.1503), the Cinder processes run under the cinder user.

/var/lock/cinder, used for concurrency, can't be created because the cinder user has no write access to /var/lock (which is a symbolic link to /run/lock).
Possible solutions: Adding write permissions for "other" on /run/lock, or setting up an ACL so that just the cinder user can access the lock directory.

Since two users have experienced this problem, it seems confirmed

[Matt Kassawara (ionosphere80)]

Packaging bug, but we know how quickly those get fixed, so we can implement a workaround.
