Creating a MegaRAID R10 configuration may fail #9

Closed tk-wfischer closed 7 years ago

tk-wfischer commented 7 years ago

The current configration file format and the currently used storcli commands may fail for a R10 with the following error:

$ sudo /usr/local/sbin/storcli /c0 add vd type=r10 drives=252:0,1,2,3,4,5,6,7 wt nora Controller = 0 Status = Failure Description = operation not possible for current RAID level, Cannot create configuration with 1 span

According to the StorCLI article in our wiki it may be neccessary to add the following parameter for a R10:

PDperArray=2

tk-wfischer commented 7 years ago

Adding the "pdperarray=2" parameter fixes the issue. I'll take a look at the TKperf code to fix it there.

tk-wfischer commented 7 years ago

Issue should be fixed with commit 81c88332f37ea782781bf51556dd42acee7060ad

I'll test it tomorrow and I'll update this issue then.

tk-wfischer commented 7 years ago

The code works, the branch has been merged to master (the pull request https://github.com/thomas-krenn/TKperf/pull/11 is closed).

So this issue is fixed and I hereby close it :-)

I has met a same condition , and fixed it with "pdperarray=2", but I don't know why! 我遇到了相同的情况,也是用"pdperarray=2"才没有报错的,但是不明白pdperarray代表的是什么意义!
