MySQL DRBD资源未能启动PaceMaker +Cor产c

Question

因此，在配置集群时，我已经运行了所有的服务，但是在重新启动之后，我得到了以下内容：

Full list of resources:

 virtual_ip     (ocf::heartbeat:IPaddr2):       Started node1
 webserver      (ocf::heartbeat:apache):        Stopped
 Master/Slave Set: WebDataClone [WebData]
     Masters: [ node2 ]
     Slaves: [ node1 ]
 WebFS  (ocf::heartbeat:Filesystem):    Started node2
 sqlfs  (ocf::heartbeat:Filesystem):    Stopped
 Master/Slave Set: SQLDataClone [SQLData]
     Masters: [ node1 ]
     Slaves: [ node2 ]

失败的操作：

    sqlfs_start_0 on node1 'unknown error' (1): call=26, status=complete, last-rc-change='Sat Jun  4 00:57:27 2016', queued=0ms, exec=32ms
    sqlfs_start_0 on node2 'unknown error' (1): call=34, status=complete, last-    rc-change='Sat Jun  4 00:57:27 2016', queued=0ms, exec=59ms

这就是我在SQL配置中使用的内容：

 resource sqldata {
 protocol C;
 disk   /dev/sdb2;
 device /dev/drbd1;

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outdated-wfc-timeout 20;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

 net {
cram-hmac-alg sha1;
shared-secret sync_disk;
  }

 syncer {
rate 10M;
al-extents 257;
on-no-data-accessible io-error;
verify-alg sha1;
  }

 on node1.freesoftwareservers.com {
   address  192.168.1.218:7788;
   flexible-meta-disk internal; 
  }

 on node2.freesoftwareservers.com {
   address  192.168.1.221:7788;
   meta-disk internal;
  }

 }

启动DRBD并同步：

drbdadm -- --overwrite-data-of-peer primary sqldata
drbdadm primary --force sqldata
watch cat /proc/drbd

修改后的my.cnf在两个服务器上都会被更改：

service mysqld stop
sudo nano /etc/my.cnf
Change in /etc/my.cnf :

#bind-address = 127.0.0.1
#Make Virtual_IP
bind-address = 192.168.1.215
#datadir=/var/lib/mysql
#Where DRBD will Mount
datadir=/var/lib/mysql_drbd
Mount and Populate with Data :

安装并填充drbd1：

/sbin/mkfs.ext4 /dev/drbd1
mkdir /mnt/drbd1
mount /dev/drbd1 /mnt/drbd1 
mv /var/lib/mysql_drbd/* /mnt/drbd1/
chcon -R --reference=/var/lib/mysql /mnt/drbd1
umount /dev/drbd1

--这是似乎失败的配置:

pcs cluster start --all
pcs cluster cib sqlfs_cfg
pcs -f sqlfs_cfg resource create sqlfs ocf:heartbeat:Filesystem device="/dev/drbd1" directory="/var/lib/mysql_drbd" fstype="ext4"
pcs -f sqlfs_cfg constraint colocation add sqlfs with SQLDataClone INFINITY with-rsc-role=Master
pcs -f sqlfs_cfg constraint order promote SQLDataClone then start sqlfs
pcs -f sqlfs_cfg constraint colocation add webserver with sqlfs INFINITY
pcs -f sqlfs_cfg constraint order sqlfs then webserver
pcs -f sqlfs_cfg constraint
pcs -f sqlfs_cfg resource show
pcs cluster cib-push sqlfs_cfg

sqlfs_drbd_cfg：

pcs cluster start --all
pcs cluster cib sqlfs_drbd_cfg
pcs -f sqlfs_drbd_cfg resource create SQLData ocf:linbit:drbd drbd_resource=sqldata op monitor interval=60s
pcs -f sqlfs_drbd_cfg resource master SQLDataClone SQLData master-max=1 master-    node-max=1 clone-max=2 clone-node-max=1 notify=true
pcs -f sqlfs_drbd_cfg resource show
pcs cluster cib-push sqlfs_drbd_cfg

在node1 AKA小学设置优先位置：

pcs constraint location sqlfs prefers node1=50

对如何排除这些问题有什么想法吗？同样，它在初始配置期间工作，并在重新启动后崩溃.

谢谢!

我没有看到mysql定义在起搏器中；您是在集群启动后手动启动它，还是在启动时启动它？

如果它是在引导时启动的，那么它可能是在Pac怪机之前启动的，因此，在挂载点(它的数据应该在那里)上持有一个锁，这将导致文件系统资源无法将文件系统挂载到那里。

有点黑暗，但是如果是这样的话，您应该在启动时禁用mysql，然后在集群中定义它。
