#625 iSCSI mount incorrectly displays disk space

[osi]

After creating a software raid 5 with four 1 TB disks, the total space available is ~2.8TB. When mounted via iSCSI through windows XP and windows server 2003 the total space is displayed only as 746 GB.

File transferring appears to work -- have not tried to exceed the 746GB limit yet.

Did you have tried 0.7.x? The iscsi-target software used in 0.6.x is not maintained anymore (this means we can not fix it if it is a bug). 0.7 uses the new 'istgt' software.

I have tried the two release candidates (i386-LiveCD-0.7RC2.4849 , i386-LiveCD-0.7RC1.4735) and both have failed to boot correctly.

Error :

Fatal trap 18: integer divide fault while in kernel mode
cpuid = 0; apic id = 00
instruction pointer = 0x20:0x80b7d459
stack pointer = 0x28:0x8703ea6c

I have successfully be able to load the os onto a different box to use.

Now I just need to figure out how to work this new iscsi stuff. This could be close IMO

I can confirm that this happens on RC1, using Intel 1366 cpu's

This is limitation of old iSCSI target. It supports only 32bit mode (2TB limit).
New iSCSI target supports 64bit LBA up to 8EB.
