Hi guys I wanted to ask how i could setup a iSCSI device to be shared by 2 computers concurrently, by that i mean sharing files like it was a NFS share but use iSCSI instead. I tried and setup iSCSI on both computers and was able to see my files (I had formatted it NTFS before), from my laptop I uploaded a 400MB video file to the root directory and from my desktop I browsed the same directory and the file was not there??

For iSCSI, you need to configure data fencing, typically handled by clustering suites from various operating systems to control which host has access to the iSCSI volumes at one time. You should stick to CIFS or NFS, or investigate a real clustered file system. -- Brent Jones brent at servuhome.net
NTFS is not a clustered file system and thus can''t handle multiple clients accessing the data. You could use MelioFS if you''re Windows based, which handles metadata updates and locking between the accessing nodes to be able to share a NTFS disk between them - even over iSCSI.

And.. if you''re using iSCSI towards ZFS and want to have shared access, take a look at GlusterFS which you use in front of multiple ZFS nodes as accessing point.

Thanks guys - I will take a look at those clustered file systems. My goal is not to stick with Windows - I would like to have a Storage pool for XenServer (free) so that I can have guests, but using a storage server (Opensolaris - ZFS) as the iSCSI storage pool. Any suggestions for the added redundancy or failover to be implemented? Also I am not sure if the "Shared Storage" on XenServer has the same problem that you mentioned NTFS has, which is only 1 host can control at the same time. -- This message posted from opensolaris.org
