Okay, so the SPM is only blocking me if I have thin provisioned block
storage that needs extending. This is luckily not the case because we
primarily use NFS. It is something though I have never thought about, in
my head the storage leases completely solved the "host crashes and power
management does not answer" until I read your mail :)


Thanks for the detailed explanation Nir!
