Hello!
If I hadn't experienced the issue I'm going to talk about I would have hardly believed it may ever happen...
I'm starting setting up a test cluster (all hosts = WinServer 2012 R2): Host3 = iSCSI target, Host1 and Host2 - cluster nodes.
1) I create three iSCSI disks on Host3: Disk1-Q (5Gb),
FS (60 Gb), Mail (60 Gb). All of them are "part" of the single target.
2) ... then make an iSCSI connection to Host3 from Host1 and Host2.
3) On Host1 I open Disk Management and create three volumes: Disk1-Q (X),FS (Y), Mail (Z).
4) I format disk X (Disk1-Q) and give it the name "QUORUM".
---------------------------------------------------------------------------------------------------------
4) Now I must open Disk Management on Host2 and make these disks online....but having connected to Host2 I see that all three disks are already online and UNformatted.
Here goes my "funny" "tests:
5) On Host2 I format THE SAME disk X (Disk1-Q) and give it another name "QUORUM2" - the operation succeeds.
6) I create the folder "hhh" on disk X (Disk1-Q) when I connected to Host1 and create the folder "kkk" onDisk1-Q when connected to Host2. Each node shows only its "own" folder onDisk1-Q...
7!) a) On Host1: I copied one iso image (3,6 Gb) to disk X (Disk1-Q) and
b) On Host2: I copied other iso image (3.1 Gb) do disk
X (Disk1-Q).
The second copy operation succeeded too!!! Now my 5Gb disk X (iSCSI disk Disk1-Q) contains two iso images that total to 6.7Gb!
...I know that's impossible...is it magic?
...but looking at the pictures above what can you say?
Thank you in advance,
Michael
