ext4 – 使用drbd进行故障恢复时的Pacemaker错误

我的群集中有两个节点,带有drbd pacemaker corosync
当第一个节点发生故障时,第二个节点就会服务并且没关系,但是当我们必须进行故障恢复(node1重新联机)时,它会显示一些错误并且集群停止工作.

它是一个内核为2.6.32-504.12.2.el6.x86_64的CentOS 6集群,这些软件包：

kmod-drbd83-8.3.16-3,drbd83-utils-8.3.16-1,corosynclib-1.4.7-1,
corosync-1.4.7-1,pacemaker-1.1.12-4,pacemaker-cluster-libs-1.1.12-4,pacemaker-libs-1.1.12-4,pacemaker-cli-1.1.12-4.

Drbd配置：

resource r0
{
    startup {
        wfc-timeout 30;
        outdated-wfc-timeout 20;
        degr-wfc-timeout 30;
    }

net {
    cram-hmac-alg sha1;
    shared-secret sync_disk;
    max-buffers 512;
    sndbuf-size 0;
}

syncer {
    rate 100M;
    verify-alg sha1;
}

on XXX2 {
    device minor 1;
    disk /dev/sdb;
    address xx.xx.xx.xx:7789;
    meta-disk internal;
}

on XXX1 {
    device minor 1;
    disk /dev/sdb;
    address xx.xx.xx.xx:7789;
    meta-disk internal;
}
}

Corosync：

res_exportfs_export2_stop_0 on xx.xx.xx.2 'unknown error' (1): call=52,exec=20001ms

还有其他我可以检查的日志吗？

我检查了第二个节点/ dev / drbd1在故障恢复时没有卸载.
如果我重新启动NFS服务并应用规则,一切正常.

编辑：感谢Dok现在正在工作,我只需要将时间调整为120秒并设置启动超时！

解决方法

res_exportfs_export2_stop_0 on xx.xx.xx.1 'unknown error' (1): call=47,exec=20003ms

显示您的res_exportfs2资源由于超时而无法停止.它可能只是需要更长的超时.尝试为此资源配置停止超时,如下所示：

primitive res_exportfs_export2 exportfs \
params fsid=2 directory="/data/teste1" options="rw,no_all_squash" clientspec="*" wait_for_leasetime_on_stop=true \
op monitor interval=30s \
op stop interval=0 timeout=60s

如果超时没有帮助检查消息日志和/或corosync.log在错误中显示的线索(2015年3月31日12:53:04).
