Hi, after successfully testing iscsi boot of a xp client pc using iscsitgtd I decided to try to use COMSTAR as iscsi target software since everybody seems to agree that it is the future and has far better speed.
Now, after spending this afternoon checking and redoing the basic steps to export a zvol as a lun through comstar just to see the xp client (booting through gPXE) fail to boot I started looking around for some clue till I found out this bug id: 6701531 It says that sbd (which I think is the sbdadm program) writes LU metadata on the first 64KB of the backing store (my zvol in this case). So, I do a dd of the xp hard disk to a zvol but as soon as I issue the sbdadm create-lu command it destroys the first 64KB of that disk image making boot impossibile (in fact, gPXE stops saying it can not boot from the disk). Now, please, tell me this is not true .) How can copy a disk image to a zvol preserving the image integrity? How can I create a LU from a zvol which already has data inside (think about moving iscsitgtd exported zvols to comstar)?
