Re: [ceph-users] my cluster has only rbd pool

[wang lin]

Hi Mark
 Thank you!
 I create a data pool as you want said, it works.
 By the way, only adding a metadata server by command "ceph-deploy mds 
create node1" still doesn't create the metadata or data pool, right?

Thanks
Lin, Wang

If you're running Ceph 0.88 or newer, only the rdb pool is created by
default now.  Greg Farnum mentioned that the docs are out of date there.

In Giant, only the 'rbd' pool is created by default. If you add an mds 
(i.e activate cephfs) then you will get 'data' and 'metadata' pools too.


If you are following the docs (which probably need to be changed because 
of this...) you can just create a 'data' pool yourself:


$ ceph osd pool create data 64 64

[ceph-users] my cluster has only rbd pool

[wang lin]

Hi All
  I set up my first ceph cluster according to instructions in 
http://ceph.com/docs/master/start/quick-ceph-deploy/#storing-retrieving-object-data
 
  but I got this error "error opening pool data: (2) No such file or 
directory" when using command "rados put hello_obj hello --pool=data".
  I typed the command "ceph osd lspools", the result only show "0 rbd,", no 
other pools.
  Did I missing anything?
  Could anyone give me some advise?

Thanks
Lin, Wangf
