In all my playing with OpenSolaris and iSCSI I decided to give iSCSI using Linux and OS X another shot. Turns out the GlobalSAN iSCSI client for OS X, available for free from Studio Network Solutions, works much better than it did just a couple of months ago. Lock ups, so far, seem to be a thing of the past.
To make use of it I decided to pull the drive out of my external case and put it in my Linux system. I then exported it via the iSCSI Enterprise Target software (available here) already installed on the system. After installing the latest GlobalSAN iSCSI initiator software (available here)on my mini I was able to connect to the iSCSI Lun on my Linux machine.
So far I’m finding that I’m able to get nearly full speed out of the disk and am able to copy large files to the drive at around 44MB/s.
Update: One caveat I have found is it takes a lot longer for the Mac to enter sleep if it is connected to the iSCSI share.
One of the first things I really hoped ZFS could do when I heard about it (and its ability to share using iSCSI) was the ability to resize things at will. Resizing file systems is something that has been possible for a while but it has never been this easy, at least in my mind. With the ability to resize storage volumes you can put a ton of disks into a single system and then share out exactly what is needed to your systems and then resize if you need more later on. Today I got a chance to test ZFS’s ability to resize volumes as well as how Windows handles the task.
Although the ability to resize file systems has been around for a while it has never been as easy as it is today. Linux has been able to resize file systems for some time and the latest versions of Windows provides the ability right in Disk Management. I run a number of Windows systems and the ability to resize NTFS iSCSI volumes is what I’m primarily interested in.
