Is there a way to disable write caching when using tgtd as a target?
Right now, it seems to be impossible (at least I didn't find an option
in documentation nor sources) and setting it on the initiator fails:
initiator# sdparm /dev/sda
/dev/sda: IET VIRTUAL-DISK 0001
Caching (SBC) mode page:
WCE 1 [cha: y, def: 1, sav: 1]
RCD 0 [cha: n, def: 0, sav: 0]
(...)
initiator# sdparm --set WCE=0 /dev/sda
/dev/sda: IET VIRTUAL-DISK 0001
change_mode_page: failed setting page: Caching (SBC)
(using tgt-20080527 and open-iscsi 2.0-869).
