From 8a7dfb0d4b856578e89898c2bb84a0a675ade50b Mon Sep 17 00:00:00 2001 From: Gaurav Kumar Garg Date: Fri, 5 Jun 2015 13:58:28 +0530 Subject: features/bitrot: tuanble object signing waiting time value for bitrot Currently bitrot using 120 second waiting time for object to be signed after all fop's released. This signing waiting time value should be tunable. Command for changing the signing waiting time will be #gluster volume bitrot signing-time Change-Id: I89f3121564c1bbd0825f60aae6147413a2fbd798 BUG: 1231832 Signed-off-by: Gaurav Kumar Garg Signed-off-by: Venky Shankar Reviewed-on: http://review.gluster.org/11105 (cherry picked from commit 554fa0c1315d0b4b78ba35a2d332d7ac0fd07d48) Reviewed-on: http://review.gluster.org/11235 Tested-by: Gluster Build System --- xlators/features/bit-rot/src/bitd/bit-rot.c | 37 +++++++++++++++++++++++------ xlators/features/bit-rot/src/bitd/bit-rot.h | 2 +- 2 files changed, 31 insertions(+), 8 deletions(-) (limited to 'xlators/features/bit-rot') diff --git a/xlators/features/bit-rot/src/bitd/bit-rot.c b/xlators/features/bit-rot/src/bitd/bit-rot.c index 81490830570..513cb1a39a7 100644 --- a/xlators/features/bit-rot/src/bitd/bit-rot.c +++ b/xlators/features/bit-rot/src/bitd/bit-rot.c @@ -753,8 +753,11 @@ br_initialize_timer (xlator_t *this, br_object_t *object, br_child_t *child, goto out; INIT_LIST_HEAD (&timer->entry); + timer->expires = (priv->expiry_time >> 1); + if (!timer->expires) + timer->expires = 1; + timer->data = object; - timer->expires = priv->expiry_time; timer->function = br_add_object_to_queue; gf_tw_add_timer (priv->timer_wheel, timer); @@ -1490,13 +1493,29 @@ br_rate_limit_signer (xlator_t *this, int child_count, int numbricks) return priv->tbf ? 0 : -1; } +static int32_t +br_signer_handle_options (xlator_t *this, br_private_t *priv, dict_t *options) +{ + if (options) + GF_OPTION_RECONF ("expiry-time", priv->expiry_time, + options, uint32, error_return); + else + GF_OPTION_INIT ("expiry-time", priv->expiry_time, + uint32, error_return); + + return 0; + +error_return: + return -1; +} + static int32_t br_signer_init (xlator_t *this, br_private_t *priv) { int32_t ret = 0; int numbricks = 0; - GF_OPTION_INIT ("expiry-time", priv->expiry_time, int32, error_return); + GF_OPTION_INIT ("expiry-time", priv->expiry_time, uint32, error_return); GF_OPTION_INIT ("brick-count", numbricks, int32, error_return); ret = br_rate_limit_signer (this, priv->child_count, numbricks); @@ -1581,6 +1600,8 @@ init (xlator_t *this) if (!priv->iamscrubber) { ret = br_signer_init (this, priv); + if (!ret) + ret = br_signer_handle_options (this, priv, NULL); } else { ret = br_scrubber_init (this, priv); if (!ret) @@ -1651,8 +1672,12 @@ reconfigure (xlator_t *this, dict_t *options) priv = this->private; - if (!priv->iamscrubber) + if (!priv->iamscrubber) { + ret = br_signer_handle_options (this, priv, options); + if (ret) + goto err; return 0; + } ret = br_scrubber_handle_options (this, priv, options); if (ret) @@ -1700,10 +1725,8 @@ struct xlator_cbks cbks; struct volume_options options[] = { { .key = {"expiry-time"}, .type = GF_OPTION_TYPE_INT, - /* Let the default timer be half the value of the wait time for - * sining (which is 120 as of now) */ - .default_value = "60", - .description = "default time duration for which an object waits " + .default_value = SIGNING_TIMEOUT, + .description = "Waiting time for an object on which it waits " "before it is signed", }, { .key = {"brick-count"}, diff --git a/xlators/features/bit-rot/src/bitd/bit-rot.h b/xlators/features/bit-rot/src/bitd/bit-rot.h index 40e02ebf378..562f17e12bc 100644 --- a/xlators/features/bit-rot/src/bitd/bit-rot.h +++ b/xlators/features/bit-rot/src/bitd/bit-rot.h @@ -162,7 +162,7 @@ struct br_private { and ready to be picked up for signing and the workers which sign the objects */ - int32_t expiry_time; /* objects "wait" time */ + uint32_t expiry_time; /* objects "wait" time */ br_tbf_t *tbf; /* token bucket filter */ -- cgit
