Hi, relevant VDSM logs were published here:
https://bugzilla.redhat.com/show_bug.cgi?id=1183977
And engine says "Failed in 'ReconstructMasterVDS' method" because of
"Cannot acquire host id: (u'ba7be27f-aee5-4436-ae9a-0764f551f9a7',
SanlockException(5, 'Sanlock lockspace add failure', 'Input/output
error'))":
If reconstruct master fails, it is expected that the old master will
be restored.
Your probably have storage issues, revealed by sanlock - it reads and write
to all storage domains every 10 seconds, so flaky storage will cause failure
to acquire a host id.
Please attach to the bug these logs:
Hypervisor:
/var/log/sanlock.log
/var/log/messages
/var/log/glusterfs/<glusterhost>:_<volumename>.log
Gluster server:
server logs showing what happened when sanlock failed access the gluster volume.
How do I specify the dataDict in the vdsClient command?
I guess it should be something like:
vdsClient -s 0 reconstructMaster
'00000001-0001-0001-0001-00000000007e' 'Default'
'ba7be27f-aee5-4436-ae9a-0764f551f9a7' '[{ domainId:
ad08adbc-b3a7-4198-a1cb-4ad70c724454, status: Unknown };{ domainId:
15674257-e14a-4693-9b95-cc4bb92aa765, status: Unknown };{ domainId:
ba7be27f-aee5-4436-ae9a-0764f551f9a7, status: Unknown };{ domainId:
3233144b-7be1-445f-9ea6-6aebbacbb93f, status: Inactive };]'
Looking in cleint/vdsClient.py:920 - it should be:
ad08adbc-b3a7-4198-a1cb-4ad70c724454=status,15674257-e14a-4693-9b95-cc4bb92aa765=status,...
Where status is the string vdsm expects. You can check what vdsm expects
or what engine is sending.
