Description Dafna Ron 2012-12-02 13:02:12 UTC
Created attachment 655977 [details]

Description of problem:

I activated one of my hosts and got wrong master domain or version. 
looking at the info from getStorageDomainInfo I can see that in only one of my hosts we see the domain with master version 0 instead of 1. 
after vdsm restart the issue was resolved
looks like it might be a cache issue

Version-Release number of selected component (if applicable):

vdsm-4.9.6-44.0.el6_3.x86_64
si24.5

How reproducible:

Steps to Reproduce:
1. in NFS, create a pool while 2 out of the 3 hosts are in maintenance
2. attach and activate iso and export domain
3. activate the two other hosts
  
Actual results:

one host is unable to connect to the pool with wrong master domain version

Expected results:

we should be able to connect to pool and not read from cache. 

Additional info:

before and after vdsm restart:
