I have set up a two node OpenStack system with a controller and a compute node using Rocky on CentOS 7 1804. It runs nicely, I can create instances, and everything runs. When the machine is rebooted, vgs shows cinder-volumes as full, with <200GB free when they should have > 7T free.

  [root@controller ~]# vgs
      VG             #PV #LV #SN Attr   VSize  VFree  
      centos           1   3   0 wz--n- <7.28t      0 
      cinder-volumes   1   3   0 wz--n- <7.28t 192.32g
    [root@controller ~]#

I can fix it, and restore the instances and it runs normally, until the next reboot. I have another nearly identical system in another location that shows no trace of this behavior. Have spent many hours of hair-pulling, and desperately need a clue of how to address. All is well, until a reboot, or even just restarting cinder. Ideas? Questions? Thoughts?
