From 14f9a6076f5388f3fd6341ad4b841337b28fc825 Mon Sep 17 00:00:00 2001 From: Weston Andros Adamson Date: Tue, 31 May 2011 18:48:57 -0400 Subject: NFS: Parse and store all multipath DS addresses This parses and stores all addresses associated with each data server, laying the groundwork for supporting multipath to data servers. - Skips over addresses that cannot be parsed (ie IPv6 addrs if v6 is not enabled). Only fails if none of the addresses are recognizable - Currently only uses the first address that parsed cleanly - Tested against pynfs server (modified to support multipath) Signed-off-by: Weston Andros Adamson Signed-off-by: Trond Myklebust --- fs/nfs/nfs4filelayout.h | 12 +++++++++--- 1 file changed, 9 insertions(+), 3 deletions(-) (limited to 'fs/nfs/nfs4filelayout.h') diff --git a/fs/nfs/nfs4filelayout.h b/fs/nfs/nfs4filelayout.h index 6c6a817710e5..68cce730b800 100644 --- a/fs/nfs/nfs4filelayout.h +++ b/fs/nfs/nfs4filelayout.h @@ -47,11 +47,17 @@ enum stripetype4 { }; /* Individual ip address */ +struct nfs4_pnfs_ds_addr { + struct sockaddr_storage da_addr; + size_t da_addrlen; + struct list_head da_node; /* nfs4_pnfs_dev_hlist dev_dslist */ + char *da_remotestr; /* human readable addr+port */ +}; + struct nfs4_pnfs_ds { struct list_head ds_node; /* nfs4_pnfs_dev_hlist dev_dslist */ - struct sockaddr_storage ds_addr; - size_t ds_addrlen; - char *ds_remotestr; /* human readable addr+port */ + char *ds_remotestr; /* comma sep list of addrs */ + struct list_head ds_addrs; struct nfs_client *ds_clp; atomic_t ds_count; }; -- cgit v1.2.1
