Hello again! I want to help you realize what is going wrong by telling you that the client blocks at a pvfs2-ls (it does not say connection refused immediatelly). It can also ping the new elastic IP normally!
I redirected the metadata server output to a file and when I checked it i didn't find anything wrong... It did all the gets - puts that are happening everytime the DB is created. Here is the output tail: get (handle: 4611686018427387903)()(key_sz:8) -> (511)(4) put (handle: 4611686018427387903)()(key_sz:8) -> (512)(4) [1329709072:419164][4413/140213703595776] TROVE:DBPF:Berkeley DB: bulk_msg: Send buffer after copy due to PERM [1329709072:419173][4413/140213703595776] TROVE:DBPF:Berkeley DB: send_bulk: Send 160 (0xa0) bulk buffer bytes [1329709072:419183][4413/140213703595776] TROVE:DBPF:Berkeley DB: //pvfs2-storage-space/27c41225/ rep_send_message: msgv = 7 logv 19 gen = 1 eid -1, type bulk_log, LSN [1][217660] perm [1329709072:419193][4413/140213703595776] TROVE:DBPF:Berkeley DB: rep_send_function returned: -30975 How can I find out why this metadata server refuses serving the client requests? Thanks again, Dimos.
