Hi,
I am not sure about cephadm but if you were to use the ceph-dashboard, in
its host creation form you can enter a pattern like ceph[01-19] should add
ceph01...ceph19.

Nizam

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.

I use something like
"^ceph(0[1-9])|(1[0-9])$", but in a script that
checks a parameter for a "correct" ceph node name like in:
wantNum=$1
if [[ $wantNum =~ ^ceph(0[2-9]|1[0-9])$ ]] ; then
wantNum=${BASH_REMATCH[1]}
Which gives me the number, if it is in the range 02-19
Dunno, if that helps :)
Ciao, Uli

Hi,
I wonder if it is possible to define a host pattern, which includes the
host names
ceph01…ceph19, but no other hosts, especially not ceph00. That means,
this
pattern is wrong: ceph[01][0-9] , since it
includes ceph00.
Not really a problem, but it seems that the "“host-pattern” is a regex
that
matches against hostnames and returns only
matching hosts"¹ is not
defined
more precisely in the docs.
