Question background description:

In our system, there are 2 server A& B, hot standby each other, respectively, using SAS line and an external storage C directly connected,

There is a logical disk in the storage is mapped to C2 disk 2 servers (corresponding stored on the same piece of logical disk),

In the A and B corresponds to generate E disk on the server, the server used between heartbeats are linked together, the diagram below:



Question:

1, if A time server A C2 disk is online status, can have some Settings can make A reboot is

Disk C2 in the offline state (A restart didn't put the C2 disk offline.), should be how to configure?

2, if can't achieve in 1, so after A start, run on A system can be based on the current state, definitely

Decide whether the disk offline, so there will be A problem, if A startup disk C2 on B

State have been online, and in the reading and writing data, and after completion of A on C2 is online on A state, although

Then in offline C2 disk, under this scenario, the disk C2 whether there will be A bad influence, will not lead to disk

The data on the C2 mistake?

A bit dizzy,,, do not intend to use clustering scheme?

CodePudding user response:

Windows cluster on the switch time do not meet our requirements,
Do need to double-click on the hot standby, real-time data switch for 10 seconds, the historical data records only a to the disk array,

CodePudding user response:

Windows cluster is a disk can't let both sides at the same time, ONLINE, or you will have a problem except (CSV)

CodePudding user response:

Windows group of concentrated iscsi server like executing judgment

Don't have a Windows cluster, their development,
