From 8277f4e4a4e92543ac139ef63d0ad82add397de7 Mon Sep 17 00:00:00 2001 From: vmallika Date: Thu, 20 Nov 2014 20:36:00 +0530 Subject: gluster/uss: Handle ESTALE in snapview client when NFS server restarted When NFS server is restarted inode-context is lost. Nameless lookup will be sent to regular volume. If the gfid is from virtual graph, lookup will fail with ESTALE. We need to send a lookup to snapview server Change-Id: I22920614f0d14cb90b53653fce95b6b70023eba6 BUG: 1166197 Signed-off-by: vmallika Reviewed-on: http://review.gluster.org/9153 Tested-by: Gluster Build System Reviewed-by: Sachin Pandit Reviewed-by: Vijay Bellur --- xlators/features/snapview-server/src/snapview-server.c | 8 ++++++++ 1 file changed, 8 insertions(+) (limited to 'xlators/features/snapview-server/src') diff --git a/xlators/features/snapview-server/src/snapview-server.c b/xlators/features/snapview-server/src/snapview-server.c index 6c65497b34c..d66150e769a 100644 --- a/xlators/features/snapview-server/src/snapview-server.c +++ b/xlators/features/snapview-server/src/snapview-server.c @@ -536,6 +536,14 @@ svs_lookup (call_frame_t *frame, xlator_t *this, loc_t *loc, dict_t *xdata) fs = svs_initialise_snapshot_volume (this, dirent->name, NULL); } + if (inode_ctx && inode_ctx->type == SNAP_VIEW_ENTRY_POINT_INODE) { + /* entry-point may not be set in the dictonary. + * This can happen if snap-view client is restarted where + * inode-ctx not available and a nameless lookup has come + */ + entry_point = _gf_true; + } + /* lookup is on the entry point to the snapshot world */ if (entry_point) { op_ret = svs_lookup_entry_point (this, loc, parent, &buf, -- cgit
