So the proper way to do this would be,

xe pool-emergency-transition-to-master
xe pool-recover-slaves

xe host-list params=uuid,name-label,host-metrics-live

xe vm-reset-powerstate resident-on=UUID-OF-FAILED-MASTER --force --multiple

/opt/xensource/sm/resetvdis.py NEW-POOl-MASTER-UUID SR-UUID master

I believe that should be the uuid of the old failed master, not the new ones, and you should do this for each SR the master had attached.

No, the fix is to run the scrip 'resetvdis.py' - see this bit of the xenserver docs: http://docs.vmd.citrix.com/XenServer/6.1.0/1.0/en_gb/reference.html#pool_failures

This is not obvious, but has been made better in the version of xapi under development at the moment, so in the next release it ought to be a bit smoother.

Hello,

I had a master of the pool fail. I did the following on the slave in the pool,

xe pool-emergency-transition-to-master
xe pool-recover-slaves

xe host-list params=uuid,name-label,host-metrics-live

xe vm-reset-powerstate resident-on=UUID-OF-FAILED-MASTER --force --multiple

now when I try to start a VM on the old slave that is now the master, I get the following,

Error code: SR_BACKEND_FAILURE_46
Error parameters: , The VDI is not available [opterr=VDI b4354ed7-3042-4874-93b4-59a392c43027 already attached RW],

I'd tried everything I can find online to fix this, the only way I'd been able to fix the important VMs was to vdi-forget them, then relabel/readd them to the VMs and start. That works, but is that REALLY the only way to fix this problem?

Also the VDIs were created shared, however, they are showing false under xe commands.

Any insight?
