But objlayout was not switched over. Fix that! Without this fix any IO error is hanged, because IO is not switched to MDS and pages are never cleared or read. [Applies to 3.2.0. Same bug different patch for 3.1/0 Kernels] CC: Stable Tree Signed-off-by: Boaz Harrosh Signed-off-by: Trond Myklebust --- diff --git a/fs/nfs/objlayout/objlayout.c b/fs/nfs/objlayout/objlayout.c index 72074e3a04f9..b3c29039f5b8 100644 --- a/fs/nfs/objlayout/objlayout.c +++ b/fs/nfs/objlayout/objlayout.c @@ -254,6 +254,8 @@ objlayout_read_done(struct objlayout_io_res *oir, ssize_t status, bool sync) oir->status = rdata->task.tk_status = status; if (status >= 0) rdata->res.count = status; + else + rdata->pnfs_error = status; objlayout_iodone(oir); /* must not use oir after this point */ @@ -334,6 +336,8 @@ objlayout_write_done(struct objlayout_io_res *oir, ssize_t status, bool sync) if (status >= 0) { wdata->res.count = status; wdata->verf.committed = oir->committed; + } else { + wdata->pnfs_error = status; } objlayout_iodone(oir); /* must not use oir after this point */
