Hi, I have installed PetaSAN 2.1 and when try to add OSD on first node getting following error:

IOError: [Errno 2] No such file or directory: '/opt/petasan/config/node_info.json'
with open(config.get_node_info_file_path(), 'r') as f:
File "/usr/lib/python2.7/dist-packages/PetaSAN/core/cluster/configuration.py", line 103, in get_node_info
node_name = config.get_node_info().name
File "/usr/lib/python2.7/dist-packages/PetaSAN/backend/cluster/deploy.py", line 56, in get_node_status
Traceback (most recent call last):
03/09/2018 08:13:43 ERROR Config file error. The petaSAN os maybe just installed.
02/09/2018 19:00:12 INFO Start settings IPs

 

OSD status showing down. I have deleted OSD's and recreated again. Same result.

You did deploy the first 3 nodes and all went well but now you can not add an osd via the Management Web ui..is this correct ?

Can you add osds to your other nodes ?

How much ram do you have ?

Do you see errors in /opt/petasan/log/ceph-disk.log ?

Hi,

 

You were right about memory per node. It was small test environment with 2 GB per node. I have increased  it to 4 GB per node. Now all OSD's are starting
