We can not increase LUSTRE_SEQ_META_WIDTH, meta sequence is allocated to client and client can loose it in case of crash and there is no recovery mechanism. MDT can not loose super sequence as it is stored on MDT disk. i=andreas.dilger i=tappro --- diff --git a/lustre/include/lustre_fid.h b/lustre/include/lustre_fid.h index 0b18f23..414d562 100644 --- a/lustre/include/lustre_fid.h +++ b/lustre/include/lustre_fid.h @@ -83,7 +83,7 @@ enum { * This is how many sequences may be in one super-sequence allocated to * MDTs. */ - LUSTRE_SEQ_SUPER_WIDTH = (LUSTRE_SEQ_META_WIDTH * LUSTRE_SEQ_META_WIDTH) + LUSTRE_SEQ_SUPER_WIDTH = ((1<< 30) * LUSTRE_SEQ_META_WIDTH) }; /** special fid seq: used for local object create. */
