Hi, I am a new user to ceph. I am using version 0.94.5. Can someone help me with this rebalancing question.
I have 1 mon and 4 OSDs, 100 pgs in my pool with 2+1 erasure coding. I have given the steps that I did below. Am I doing these correctly? Why are UP and acting showing differently in step 10. To test rebalancing, I did the following steps: 1.
When I put and object, osd map showed the following pgs were in UP and ACTING – 1,0,3 (health is OK) 2.
I manually stopped my osd.1 and the map changed to NONE,0,3
3.
After 5 min, map changed to 2,0,3 (health is OK) 4.
I manually started my osd.1 and the map changed to 1,2,3 (health is OK) 5.
Then I stopped my osd.2 and the map changed to 1,NONE,3 6.
After 5 min, map changed to 1,0,3 (health is OK) 7.
I manually started my osd.2 and the map changed to 2,0,3 (health is OK) 8.
Then I stopped my osd.3 and the map changed to 2,0,NONE 9.
At this point even after waiting for 15 min, the map did not change, still stuck at NONE
10.
Then I started my osd.3 and still the map did not change and health is warnings, with 37 pgs degraded, 100 pgs unclean and 37 pgs stuck undersized. The map shows UP (3,NONE,0) and acting (3,0,0) Thanks Sudha |
