Comment 1 Allon Mureinik 2014-06-17 07:56:31 UTC

This is required as part of the fencing improvements.
Need to coordinate with the infra team on what would serve their needs better, but there are two options here (run from the fencing proxy):

1. Change fenceNode's signature and add a parameter requiredStorages={}, so that the fencing will only happen if the node is not renewing its lease on the given domains.

2. Add a new API call doesNodeRenewLease(nodeDetails, storageDomains) to return boolean if the lease(s) is(are) being maintained.

Comment 2 Allon Mureinik 2014-06-17 15:32:30 UTC

Nir, please check if ClusterLock.hasHostId does the trick for us.
