NFS/flexfiles: Use the correct TCP timeout for flexfiles I/O

2019-06-28T15:48:52Z

Fix a typo where we're confusing the default TCP retrans value (NFS_DEF_TCP_RETRANS) for the default TCP timeout value. Fixes: 15d03055cf39f ("pNFS/flexfiles: Set reasonable default ...") Cc: stable@vger.kernel.org # 4.8+ Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

pNFS: Add tracking to limit the number of pNFS retries

2019-04-25T18:18:14Z

When the client is reading or writing using pNFS, and hits an error on the DS, then it typically sends a LAYOUTERROR and/or LAYOUTRETURN to the MDS, before redirtying the failed pages, and going for a new round of reads/writebacks. The problem is that if the server has no way to fix the DS, then we may need a way to interrupt this loop after a set number of attempts have been made. This patch adds an optional module parameter that allows the admin to specify how many times to retry the read/writeback process before failing with a fatal error. The default behaviour is to retry forever. Signed-off-by: Trond Myklebust Signed-off-by: Anna Schumaker

pNFS/flexfiles: Fix layoutstats handling during read failovers

2019-03-23T16:03:58Z

During a read failover, we may end up changing the value of the pgio_mirror_idx, so make sure that we record the layout stats before that update. Signed-off-by: Trond Myklebust

NFS/flexfiles: Clean up mirror DS initialisation

2019-03-02T03:37:39Z

Get rid of the redundant parameter and rename the function ff_layout_mirror_valid() to ff_layout_init_mirror_ds() for clarity. Signed-off-by: Trond Myklebust

NFS/flexfiles: Remove dead code in ff_layout_mirror_valid()

2019-03-02T03:37:38Z

nfs4_ff_alloc_deviceid_node() guarantees that if mirror->mirror_ds is a valid pointer, then so is mirror->mirror_ds->ds. Signed-off-by: Trond Myklebust
