From 606fe093b804cb133e27de2d7d21baeba4fb3944 Mon Sep 17 00:00:00 2001 From: Pranith Kumar K Date: Thu, 19 May 2016 16:24:09 +0530 Subject: cluster/afr: Do not inode_link in afr Race is explained at https://bugzilla.redhat.com/show_bug.cgi?id=1337405#c0 This patch also handles performing of self-heal with shd-pid. Also performs the healing with this->itable's inode rather than main itable. >BUG: 1337405 >Change-Id: Id657a6623b71998b027b1dff6af5bbdf8cab09c9 >Signed-off-by: Pranith Kumar K >Reviewed-on: http://review.gluster.org/14422 >Smoke: Gluster Build System >NetBSD-regression: NetBSD Build System >CentOS-regression: Gluster Build System >Reviewed-by: Krutika Dhananjay BUG: 1337872 Change-Id: I6d8e79a44e4cc1c5489d81f05c82510e4e90546f Signed-off-by: Pranith Kumar K Reviewed-on: http://review.gluster.org/14456 NetBSD-regression: NetBSD Build System CentOS-regression: Gluster Build System Smoke: Gluster Build System --- xlators/cluster/afr/src/afr-common.c | 6 +--- xlators/cluster/afr/src/afr-self-heal-metadata.c | 42 ++++++++++++++++++++++++ xlators/cluster/afr/src/afr-self-heal.h | 3 ++ 3 files changed, 46 insertions(+), 5 deletions(-) (limited to 'xlators/cluster') diff --git a/xlators/cluster/afr/src/afr-common.c b/xlators/cluster/afr/src/afr-common.c index a346454bcce..d5a5ae14453 100644 --- a/xlators/cluster/afr/src/afr-common.c +++ b/xlators/cluster/afr/src/afr-common.c @@ -1953,13 +1953,9 @@ afr_lookup_sh_metadata_wrap (void *opaque) if (first == -1) goto out; - inode = inode_link (local->inode, NULL, NULL, &replies[first].poststat); - if(!inode) + if (afr_selfheal_metadata_by_stbuf (this, &replies[first].poststat)) goto out; - afr_selfheal_metadata (frame, this, inode); - inode_unref (inode); - afr_local_replies_wipe (local, this->private); dict = dict_new (); diff --git a/xlators/cluster/afr/src/afr-self-heal-metadata.c b/xlators/cluster/afr/src/afr-self-heal-metadata.c index d6daadc2ba6..014d53b38f4 100644 --- a/xlators/cluster/afr/src/afr-self-heal-metadata.c +++ b/xlators/cluster/afr/src/afr-self-heal-metadata.c @@ -435,3 +435,45 @@ unlock: afr_replies_wipe (locked_replies, priv->child_count); return ret; } + +int +afr_selfheal_metadata_by_stbuf (xlator_t *this, struct iatt *stbuf) +{ + inode_t *inode = NULL; + inode_t *link_inode = NULL; + call_frame_t *frame = NULL; + int ret = 0; + + if (gf_uuid_is_null (stbuf->ia_gfid)) { + ret = -EINVAL; + goto out; + } + + inode = inode_new (this->itable); + if (!inode) { + ret = -ENOMEM; + goto out; + } + + link_inode = inode_link (inode, NULL, NULL, stbuf); + if (!link_inode) { + ret = -ENOMEM; + goto out; + } + + frame = afr_frame_create (this); + if (!frame) { + ret = -ENOMEM; + goto out; + } + + ret = afr_selfheal_metadata (frame, this, link_inode); +out: + if (inode) + inode_unref (inode); + if (link_inode) + inode_unref (link_inode); + if (frame) + AFR_STACK_DESTROY (frame); + return ret; +} diff --git a/xlators/cluster/afr/src/afr-self-heal.h b/xlators/cluster/afr/src/afr-self-heal.h index afc086c0560..f54eb9cf23e 100644 --- a/xlators/cluster/afr/src/afr-self-heal.h +++ b/xlators/cluster/afr/src/afr-self-heal.h @@ -277,4 +277,7 @@ afr_locked_fill (call_frame_t *frame, xlator_t *this, int afr_choose_source_by_policy (afr_private_t *priv, unsigned char *sources, afr_transaction_type type); + +int +afr_selfheal_metadata_by_stbuf (xlator_t *this, struct iatt *stbuf); #endif /* !_AFR_SELFHEAL_H */ -- cgit
