> Hi,
> Thanks for developing CloudStack!
> If the following conditions are met:
> - more than one storage adaptor is defined for a KVM storage pool
> - a disconnectPhysicalDiskByPath() request comes in for the pool (the KVMStoragePoolManager.disconnectPhysicalDiskByPath() method is invoked)
> - the loop in that method finds the iSCSI adaptor first
> - the disk being disconnected is *not* managed by the iSCSI adaptor
> ....then the IscsiAdmStorageAdaptor.disconnectPhysicalDiskByPath() will return a "true" value, signalling that the request has been handled, while it has actually been silently ignored.
> A patch making the iSCSI storage adaptor return "false" (thus allowing other storage adaptors to process the request and actually disconnect the disk) is available as a GitHub pull request at https://github.com/apache/cloudstack/pull/1780
> Thanks in advance for your time and consideration!
> Best regards,
> Peter
