Subject: OSDMonitor: don't allow creation of pools with > 65535 pgs
Date: Fri, 14 Dec 2012 08:41:02 -0700	[thread overview]
Message-ID: <50CB488E.3090005@sandia.gov> (raw)

Hi,

I'm looking at commit e3ed28eb2 in the next branch,
and I have a question.

Shouldn't the limit be pg_num > 65536, because
PGs are numbered 0 thru pg_num-1?

If not, what am I missing?

FWIW, up through yesterday I've been using the next branch and this:

  ceph osd pool set data pg_num 65536 --allow-experimental-feature
  ceph osd pool set metadata pg_num 65536 --allow-experimental-feature
  ceph osd pool set data pgp_num 65536 --allow-experimental-feature
  ceph osd pool set metadata pgp_num 65536 --allow-experimental-feature

using cephfs clients, and have seen no trouble with
misdirected ops, etc.

-- Jim
