From mboxrd@z Thu Jan 1 00:00:00 1970 From: sagi@grimberg.me (Sagi Grimberg) Date: Thu, 12 Apr 2018 11:06:52 +0300 Subject: [PATCH v1 0/3] nvmet-rdma automatic port re-activation Message-ID: <20180412080656.1691-1-sagi@grimberg.me> When a RDMA device goes away we must destroy all it's associated RDMA resources. RDMa device resets also manifest as device removal events and a short while after they come back. We want to re-activate a port listener on this RDMA device when it comes back in to the system. In order to make it happen, we save the RDMA device node_guid on a ULP listener representation (nvmet_rdma_port) and when a RDMA device comes into the system, we check if there is a listener port that needs to be re-activated. In addition, reflect the port state to the sysadmin nicely with a patch to nvmetcli. Changes from v0 (rfc): - renamed tractive to trstate - trstate configfs file without addr_ prefix to prevent json serialization on it - nvmet_rdma_port_enable_work self requeue delay was increased to 5 seconds Israel Rukshin (2): nvmet: Add fabrics ops to port nvmet: Add port transport state flag Sagi Grimberg (1): nvmet-rdma: automatic listening port re-activation drivers/nvme/target/configfs.c | 11 ++ drivers/nvme/target/core.c | 17 ++- drivers/nvme/target/nvmet.h | 3 + drivers/nvme/target/rdma.c | 237 ++++++++++++++++++++++++++--------------- 4 files changed, 175 insertions(+), 93 deletions(-) -- 2.14.1
