我有一堆VM服务器通过Open-iSCSI从安装在Dom0主机中的iSCSI LUN运行Xen VM.它只是一个简单的单路径设置(冗余在目标端通过集群存储和虚拟IP)
我正在考虑使用Open-iSCSI README for iSCSI root的设置,因为它基本上是这样的:
8.2 iSCSI settings for iSCSI root
---------------------------------
When accessing the root parition directly through a iSCSI disk, the
iSCSI timers should be set so that iSCSI layer has several chances to try
to re-establish a session and so that commands are not quickly requeued to
the SCSI layer. Basically you want theopposite of when using dm-multipath.
For this setup, you can turn off iSCSI pings by setting:
node.conn[0].timeo.noop_out_interval = 0
node.conn[0].timeo.noop_out_timeout= 0
And you can turn the replacement_timer to a very long value:
node.session.timeo.replacement_timeout = 86400
是否有任何其他建议的设置用于在iSCSI LUN上运行具有root权限的VM我应该考虑哪些?
