Hi, I have a centos 6.5 cluster that are connected to a Fibre Channel SAN in star topology. All nodes/SAN_storages have single-pair fibre connection and no multipathing. Possibility of hardware issue had been eliminated because read/write between all other node/SAN_storage pairs works perfectly. Problem: Everything was running perfectly for years. Then node3 suddenly has very slow write to SAN_storage1, ~10KB/sec. Read speed seems to remain normal. Can anyone give be some pointers to debug the problem. Thank you.
