Past weekend (as usual O_o) we have experienced the issue in our XCP 1.6 production pool.
Shared iSCSI storage was shutted down due to misconfigured UPS settings while XCP servers continued to work.

When storage was returned to working state and reconnected to pool most VM did not boot with the same message - VDI is not available.
Googling give me mentioned above method - forgot and reconnect VDI.

Result was even worser - the whole SR become unusable.
Storage rescan gazered lot of errors like bad header on LVM and many other.

Finally i've disconnect failed SR from pool, connect it back and SR become healthy (it looks so). But anyone VM was not start with disk from this SR and freeze during startup.

I did not find solution and restored most VMs from backup (long live VMPP!)

So, i just wanna say - be highly careful with VDI on shared storage repository in production environment)

Subject: [Xen-API] The vdi is not available

Guys need help trouble shooting this issue

I have an xcp 1.6 pool with 3 machines A,B, and C

I can migrate from A to B and B to A

WE cannot migrate from A or B to C, we also cannot shutdown a vm and start it up on C, when we do that we get the message The vdi is not available.

We have tried removing machine C from the pool and re joining and still have the issue.

when we first add host C to the pool it cannot load the nfs storage repository because we need to create a management interface from a bonded vlan that gets created after joining the pool. After we create the interface and run a re plug on the storage repository it says its connected / re plugged.

Thanks for any help in advance
