Hi,


1st post so please be gentle!

I am having some issues with a NAS box I have it isnt booting so I have been trying to determine if its a disk or board issue.

The NAS was configured as RAID0 , I have backed the data up so that isnt an issue.

I have removed the disks and inserted them into a RAID USB enclosure I have and am trying to mount the array under knoppix.


The array doesnt mount automatically but I can see the disk using fsck , it comes up as single disk.

Any ideas on how to mount this array so I can read and check the disks?

All help appreciated !

Cheers

Typically a NAS device is somewhat proprietary in nature. NAS = Network Attached Storage which implies it shares out disks as CIFS or NFS filesystems via standard (ethernet) networking. You appear to be confusing that with SAN (Storage Area Networking) which presents disks or LUNs from the array to the OS via fibre channel, iSCSI or fibre over copper so that it appers to be a disk from the OS point of view.

Because NAS is typically proprietary there is a good chance whatever it did to setup an array was for its own filesystem share and that array isn't going to be recognized by anything from other vendors like your USB enclosure.

For a NAS you don't format at the target host machine - you simply mount the filesystem that is shared out from the source NAS. For a SAN you DO format at the target host machine because it sees the disks (or LUNs) much the same way as it would see disk (or LUNs) physically in the target.

For a NAS you typically have to configure the shares including what systems are allowed to mount them. For SAN you typically "map" the disks or LUNs to the target hosts.
