Hello Team,

After performing FFU, secret ID (ceph FSID) is not updated in cinder & nova DB for already created volumes which in result is affecting production VMs(Boot from Volume) whereas VMs(boot from image) are working fine.

VM in NOSTATE with below error

old FSID = 20c4eedc-860a-4da5-b381-4261c97af87f
new FSID = 2032fc65-0794-461b-8153-7a89ea6094b0

We can see old fsid in the connection info of block_device_mapping table of nova db.
