Description
@OSDService::ScrubJob::ScrubJob(const spg_t& pg, const utime_t& timestamp,
double pool_scrub_min_interval,
double pool_scrub_max_interval, bool must)
: pgid(pg),
sched_time(timestamp),
deadline(timestamp)
{
// if not explicitly requested, postpone the scrub with a random delay
if (!must) {
double scrub_min_interval = pool_scrub_min_interval > 0 ?
pool_scrub_min_interval : g_conf->osd_scrub_min_interval;
double scrub_max_interval = pool_scrub_max_interval > 0 ?
pool_scrub_max_interval : g_conf->osd_scrub_max_interval;
sched_time += scrub_min_interval;
double r = rand() / RAND_MAX;@r will always be 0.
