Congrats on the new version! If I wasn't leaving for vacation in a few days, I'd test it out immediately. Will check back in a couple of weeks. 03.jpg This needs some more explanations. When should I select these options? What are the performance implications? What does "deletion support"...

Cool. Looking forward to test V8!

Cheers,
Simon

were this really SAS disks with problem? Once i had big speed troubles with WD SATA RAID disks on a HP SAS controller. Now i have also SATA disks.

Sorry, can't remember, was some time ago. Can't you connect a single SATA disk, just for testing?

HA: What does "Restore Current Node" do? We are going to rename it to "Mark as synchronized" and show the warning message "this command changes the device status to 'synchronized' without data synchronization with HA partner.The device will start processing client requests ...

Wow, you worked a lot on the new release!!! I'm impressed. Here's the updated list of my observations for version 5.8.1855_beta (build 20111230), new things first: HA: What does "Restore Current Node" do? Managing an old version results in RTFM error message. Repro: Try to add a target to ...

Have you tried attaching the disks directly, not through the PERC 5/iR? I once set up some Dell servers that had disastrous performance. As soon as I used dirt-cheap SATA disks, connected to the board (the mainboard had connectors too), the problem disappeared. I saw the same problems you describe h...

I know this is no "Feature Request" forum, but I'll post here anyway, to give you a rough idea of what features one person (me) would like. Feel free to ignore me. :) My dream version would have more flexibility of the storage: I'd create a LUN, then, one day, make it HA. A month later I c...

Hi wow, you guys are quick to answer! I agree with everything said, but have a couple of comments Setup asks me if I want to install StarPort. Why would I want to install it? Why not? It is used as a transport for replication to remote target in Mirror devices. I thought the new version uses it's ow...

Here's the list of my observations, in no particular order: Why is there a gorilla in a splash screen? And where does the hippo come from? Corporate identity, anyone? Setup asks me if I want to install StarPort. Why would I want to install it? Why not? When trying to create an image in non-existent ...

I'm in no relation with the paper's authors. I just stumbled over it and thought you might be interested, because I found it an interesting read.

Edited the message with yet another link

Hi guys Here's an interesting paper about reliable block storage replication, usable for VMs, if you haven't seen it yet: http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.178.9190&rep=rep1&type=pdf The proposed solution supports replication, checksumming, branching, snapshotting and ...

I finally found the root of the problem. After some heavy debugging sessions I discovered that a write to a certain region caused the delay. Further testing revealed that one hard disk was buggy - I replaced it, did some more tests and could no longer reproduce the problem. But I still don't quite g...

According to the Microsoft-iSCSI-Logo-Requirements-1.0.doc: "If the size of a logical unit is changed, the target must report a Unit Attention condition of (06/3F/0A) VOLUME SET CREATED OR MODIFIED or (06/28/00) NOT READY TO READY CHANGE, MEDIUM MAY HAVE CHANGED" I never tested it but it s...

Discarding (freeing memory w/o data written to disk) cache is an extremely effective way to render whole volume useless. As a result who-knows-how-many last writes would not reach the medium. So the answer to you question is: NEVER. (When would discarding cached data ever make sense? [Except under ...
