iSCSI initiator + disk storage

jdr@shd

Hello everyone.



I'm actually using a iSCSI initiator (GlobalSan Initiator) to connect a big disk storage system.

So, the initiator is installed in two Mac Pro. Great access, great performance.



The question is, that scenario works perfectly...except for the integrity of data when I use the LUN (I mean, with the globalsan connection) in two or more Mac.



I found that randomly, the disks lost her integrity. Mac is unable to write inside, etc.

I think that disk format is the cause. All the partitions detected in Mac, were formatted with HFS+, but this format is not like called "clustered" or something like xSAN. Then, it fails like when you connect to a LUN from a Windows and format it with NTFS. Windows will be the owner of partition tables, and any other Windows, doesn't will able to use this disk storage, right?

I supose that HFS+ is not capable to work with two or more connections.



So, do you know any other way to do that? I mean, there is any other disk format to apply?, to working properly in two or more Mac?



Thanks in advance

As long as the LUN's are formatted as NTFS or HFS or whatever you can't have 2 machines accessing them at the same time. Causes issues as you have seen. You need to use a file system that can handle such a thing. I had the same issue awhile back. NAS type stuff (AFP, or SMB) is fine for smaller things, but I deal in video, and need block level access. You can read video off a SMB share, but forget about trying to capture to it.



Basically I gave up once I realized that all options to do what you describe are more expensive then just buying all the editors a few 2TB drives and then got a QNAP NAS to archive raw video.
