Description

The patch from review 4068 seems to use the wrong uuid for MDT0000, causing error messages like this:

LustreError: 137-5: UUID 'lustre-MDT0000-MDT0000_UUID' is not available for connect (no target)
LustreError: 11-0: an error occurred while communicating with 0@lo. The mds_connect operation failed with -19

[root@fat-amd-1 tests]# cat /proc/fs/lustre/osp/*/ost_server_uuid
lustre-MDT0000-MDT0000_UUID     DISCONN
lustre-MDT0000-MDT0000_UUID     DISCONN
lustre-MDT0000-MDT0000_UUID     DISCONN
lustre-OST0000_UUID     FULL
lustre-OST0001_UUID     FULL

Somehow, we end up with MDT0000 twice in the UUID. This is harmless for now because nobody uses this connection, but this should be fixed ASAP.

I talked to wangdi and he said that he is going to look into this issue.
