Thanks, Ulrich, but:
# ceph orch host ls --host_pattern="^ceph(0[1-9])|(1[0-9])$"
0 hosts in cluster whose hostname matched "^ceph(0[1-9])|(1[0-9])$"
Bash pattern are not accepted. (I tried it in numerous other combinations).
But, as I said, not really a problem - just wondering what the regex might
be.
