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

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：
Feb8 09:56:16 cluster1 qlc: NOTICE: Qlogic qlc(0,0): Loop OFFLINE
Feb8 09:56:16 cluster1 scsi: WARNING: /pci@0,0/pci8086,65f9@6/pci1077,15d@0/fp@0,0/disk@w210000d02308005c,1 (sd2):

Feb8 09:56:16 cluster1 scsi: ASC: 0x29 (power on, reset, or bus reset occurred), ASCQ: 0x0, FRU: 0x0

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.
see: http://www.sun.com/msg/ZFS-8000-8A
scrub: scrub completed after 0h0m with 2 errors on Mon Feb8 10:05:29 2010
config:

   mynas    ONLINE    0 0 0
      c11t112d1ONLINE    0 0 022K repaired

errors: Permanent errors have been detected in the following files:

   <metadata>:<0x1>
   <metadata>:<0x15>

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 发表于 2010-02-08 14:53

能让zpool启动的时候不自动加载吗？

diyer_xu 发表于 2010-02-08 18:34

自己顶

diyer_xu 发表于 2010-02-10 15:15

谢谢，用cachefile实现了。

日志怎么看的？求指导

回复 7# diyer_xu

能写一下cachefile 的方法么？
