List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Cc: Lustre Development List MIME-Version: 1.0 Errors-To: lustre-devel-bounces@lists.lustre.org Sender: "lustre-devel" From: Etienne AUJAMES The chlg_load use the LLOG_CAT_FIRST to process changelogs. This values will process record in the catalog always starting with index 0 to the newest record. So when catalog reach the end of indexes and when records are saved at the beginning of catalog, the llog_cat_process will ignore records at the end. This patch change the "startcat" value LLOG_CAT_FIRST to 0 to scan the catalog from the oldest record to the newest.
