Can't get the Raid-1 Mirror to work

Post by WebGuy » Sat Nov 14, 2009 12:14 pm

Trying to test the Raid-1 mirror but getting an syhcronization error.

When I create the Raid-1 Mirror I choose to create a new local .img file. I choose remote ISCSI device and put in the IP address of the ISCSI device (a different brand of San, not iStorage) and see the disk I want when I hit the discovery button and choose the proper target. When I tell it to synchronize it gives me a non-descript error. See the attachment

I've tested this feature with iStorage Server as second iSCSI target, but unfortunately not reproduced the problem.
We will check the problem to find the message problem.
Is the target a software which I can get it? you can send mail to us for detail if you like. [email protected]

Olivia,

I set up a second iStorage server to act as a mirror and then tried again. It did work when I used a istorage server as a Raid Mirror.

One thing I noticed in testing is if the Mirrored iscsi target is down, then the primary target marks the mirrored volume as disabled. I guess thats because there are no tools to do manual synchronization as some other ISCSI target software have. If data was allowed to be added to the primary while the mirroring target server was down everything would be out of sync.

Still have perfomance issues using gigabit and 10g NIC's. We have a dedicated VLAN for our ISCSI traffic. Was wondering if your product was designed to work on shared switches (regular data and ISCSI traffic mixed) and performace was throttled to keep the ISCSI traffic from overwhelming the NIC card.

Thanks!
