Pawel Jakub Dawidek 58804a192e The same code is used to import and to create pool. ... The order of operations is the following: 1. Try to open vdev by remembered path and guid. 2. If 1 failed, try to find vdev which guid matches and ignore the path. 3. If 2 failed this means either that the vdev we're looking for is gone or that pool is being created and vdev doesn't contain proper guid yet. To be able to handle pool creation we open vdev by path anyway. Because of 3 it is possible that we open wrong vdev on import which can lead to confusions. The solution for this is to check spa_load_state. On pool creation it will be equal to SPA_LOAD_NONE and we can open vdev only by path immediately and if it is not equal to SPA_LOAD_NONE we first open by path+guid and when that fails, we open by guid. We no longer open wrong vdev on import. MFC after: 2 weeks		2010-03-19 20:14:27 +00:00
