Subject: [PATCH v2 0/5] SUNRPC: Create sysfs files for changing IP
Date: Tue, 2 Feb 2021 13:42:39 -0500 [thread overview]
Message-ID: <20210202184244.288898-1-Anna.Schumaker@Netapp.com> (raw)
From: Anna Schumaker <Anna.Schumaker@Netapp.com>
It's possible for an NFS server to go down but come back up with a
different IP address. These patches provide a way for administrators to
handle this issue by providing a new IP address for xprt sockets to
connect to.
Chuck has suggested some ideas for future work that could also use this
interface, such as:
- srcaddr: To move between network devices on the client
- type: "tcp", "rdma", "local"
- bound: 0 for autobind, or the result of the most recent rpcbind query
- connected: either true or false
- last: read-only timestamp of the last operation to use the transport
- device: A symlink to the physical network device
Changes in v2:
- Put files under /sys/kernel/sunrpc/ instead of /sys/net/sunrpc/
- Rename file from "address" to "dstaddr"
Thoughts?
