I have a iSCSI target on a customer place I'm using from an old Fedora (Core6) server. I configured it and formatted as ext3 (mistake, now I know) and I've been working with it for some time.
Now I need to access this volume from other machine. As far as I've read, I can't do it safely from two machines at the same time (yep, that's the first thing I tried). So I've umount it from original server and tried to mount it on the new server (I did it at first with Ubuntu 10 LTS but when I was unable to do it I installed another Fedora with the same configuration) with no success.
The problem: I can see all target on NAS but when I do a "fdisk -l" to see all devices and know which mount I see all targets as SFS filesystem. From the original server I see all SFS (after all, they belong to my customer and don't know what he have in) except the one I manage which I see as 'Linux'.
Here it is the partition table as seen in the server (Fedora) which see it right. Spanish language, sorry. I hope it can be understood. My comments between [...]

On the machine I'm trying to configure, the one which should access the drive (but don't) I see the offending target as:
[....]
Disk /dev/sdc: 2147.4 GB, 2147483649024 bytes
255 heads, 63 sectors/track, 261083 cylinders

Device Boot Start End Blocks Id System
/dev/sdc1 1 261083 2097149166 42 SFS
[....]
And I see rest of targets as SFS, the same as in first case.
Thank you in advanced,
fdisk -l
so that we could see that the target in question is not visible. What's your iSCSI target? Am I correct that Fedora is an initiator in terms of iSCSI topology and the target is exported by some other device?
