where is it using 700 GB? it can't be - I simply don't have 700 for it to be using.
That's the max size it could ever be. A duplicate of the amount for the drive it is snapshotting. (Is that a word?)
Yes

Both yes, that is what you are seeing and yes, that is a word.

Yes
I used the layman terms. Because I am, well, you know...

Does XS support reclaiming/compacting space in a virtual disk?
I know it says it does not support shrinking a virtual disk, but can you reclaim (compact) that space?

am I mising something? Isn't shrinking the same as reclaiming?

I don't think so, but I could be wrong.
Reclaiming is adjusting the size of the virtual disk on the host to accomodate for deleted data.

Reclaiming is adjusting the size of the virtual disk on the host to accomodate for deleted data.
And shrinking is?

Actually changing the provisioned size of the virtual disk.
So if you set it up for 50GB, you could expand to 60GB, but not shrink to 40GB.
-
So you're asking if, assuming a thin provisioned disk of 50 GB has 40 GB in use, then you delete 20 GB, leaving you with 40 GB actual file.. is there a way to release that now free 20 GB space, reclaiming the RS space.
good question.

Right. You can do it in Hyper-V (I think). There is a COMPACT option.

yeah I'm not surprised.. you can do the same with SQL and Exchange DBs, though it normally (if not completely) requires taking those systems offline.
when i needed to to this for SQL in the past, I just do a backup and restore.. was faster than a compact
-
I found it interesting that XS stores the virtual hard drives in VHD format.
Opens right up in Hyper-V/Windows.

Yeah the system/VHD definitely has to be offline.

I have decided to give XenServer a try in the production environment.
I installed it for reals on our new server.
Had another install question...
If you have more than one partition and select both, it says it will span the storage repository across them. Is that ever a good idea?In my situation here, I have a SSD array and a SATA array, so I assume spanning them would be a terrible idea.
-
huh... what is the plan for the two different arrays?
-
Well, as of now, unknown.
The SSD is more than I need. I might just end up not using the SATA array.
My thought was use it for storage for backups and stuff, but that probably would be best done on another machine.
But, I was just curious as to that option.
-
Another question:
When you do a fresh install, and there are, say 20 updates available, with a service pack being the last one...can you just install the service pack? Or do you need to install all the updates up to the service pack?
-
This article seems to say the SP includes all previous updates.
http://support.citrix.com/article/CTX142355
Just want to be 100% sure.
-
Nope.. some include some older ones.. but not all.
You can start with the newest and work backwards, refreshing the list of needed updates each time.

Sorry, I did not ask a complete question.
I meant to ask can you just install the SP to cover all the updates previous to that.
Which I think from the link I posted and what you said will be OK.
