I just found that kernel 3.6 brought a regression to me as the SEEK_10 command is not longer supported. The SEEK_10 and some other commands were removed in commit 1fd032ee10d2816c947f5d5b9abda95e728f0a8f "target: move code for CDB emulation". We are using KVM virtual machines a lot to run legacy systems which are still on SCSI-2 level, and which are using the following old commands even on hard disks: WRITE_VERIFY // supported by LIO RESERVE // supported by LIO RELEASE // supported by LIO REZERO_UNIT SEEK_10 I found that many real SCSI disks or external iSCSI storage devices still support these old commands. So it would be nice if LIO would do as well. Is this OK? The implementation for the REZERO_UNIT and SEEK_10 commands can be empty, i.e simply returning status GOOD. I would like to post a patch for REZERO_UNIT, SEEK, SEEK_10.
