cluster可以通过clrg switch命令手动切换，但如果是reboot自动切换，会导致数据冲突

diyer_xu

我在组下用SUNW.HAStoragePlus:6资源类型建共享Zpool资源，
现在问题是通过clrg switch命令，可在双机间自由切换，但是如果我reboot当前Zpool挂起的节点（reboot非活动节点没有问题），就会发生数据冲突。
重启时在另一个节点日志里有以下记录：

然后查看pool状态，可能就是以下样子：
root@cluster2:~# zpool status -v
  pool: mynas
state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible.  Otherwise restore the
        entire pool from backup.

还有一个现象是我重启后，zpool会在两个节点上都import，按理reboot的时候，会将资源切换到另一个节点，重启的机子重新起来后，就不应该看到这个POOL了。

cachefile String N/A Controls where pool configuration information is cached. All
pools in the cache are automatically imported when the system
boots.However, installation and clustering environments
might need to cache this information in a different location so
that pools are not automatically imported. You can set this
property to cache pool configuration in a different location
that can be imported later by using the zpool import -c
command. For most ZFS configurations, this property would
not be used.

楼上什么意思，不是太懂。

diyer_xu

能让zpool启动的时候不自动加载吗？

diyer_xu

自己顶

diyer_xu

谢谢，用cachefile实现了。

日志怎么看的？求指导

    能写一下cachefile 的方法么？
