2 probs after upgrading ceph-cluster

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

maybe you can help us with following probs:

if you need more info about our cluster or any debugging log I will be happy to help

 

Environment:

-------------------

 

Small test cluster with 7 node, 1 osd per node

Upgrade from dumpling to emporer 0.72.1

 

 

2 Problems after upgrade:

-----------------------------------

 

- ceph -s shows <health HEALTH_WARN pool images has too few pgs>

  - changing pg_num etc from 1024 to 1600 has no effect

  - after setting <mon_pg_warn_min_objects> to a larger value the cluster moves to HEALTH_OK

 

- 20 pools

  create new pool

  wait until pool is ready

  delete pool again

  ceph -s still shows 21 pools

 

  stop first mon, wait, start mon again

  ceph -s shows 20 pools, 21 pools, 20 pools, ... changing every n (~ 2) secs

 

  stop second mon, wait, start mon again

  ceph -s shows 20 pools, 21 pools, 20 pools, ... changing every m > n secs

 

  stop third mon, wait, start mon again

  ceph -s shows 20 pools ... stable

 

 

Some infos about the cluster:
