可能是他unable to join drbd events multicast group的原因我的文件同步不成功
[root@file1 d]# service drbd status
drbd driver loaded OK; device status:

unable to join drbd events multicast group
这个查了下源代码

 

 1357 	if (cm->continuous_poll) {

 1358 		if (genl_join_mc_group(drbd_sock, "events") &&

 1359 		    !kernel_older_than(2, 6, 23)) {

 1360 			fprintf(stderr, "unable to join drbd events multicast groupn");

 1361 			return 20;

 1362 		}

 1363 	}

好像是内核版本要高于2.6.23

至于 adjust disk: r0:failed(attach:10)
从主日志上来看
Feb 16 18:43:37 file1 kernel: block drbd1: Requested disk size is too big (1048576 > 7992)
Feb 16 18:43:37 file1 kernel: block drbd1: peer( Unknown -> Secondary ) conn( WFReportParams -> Connected ) pdsk( DUnknown -> Diskless )

似乎是主和从两边resource限制不一致？或者是从服务器分区中有一些不一致的内容？或是硬盘设置方面不一致？

从
Device Boot Start End Blocks Id System
/dev/sdb1 261 261 8032+ 83 Linux

主
