Dear List, i have connected an new ESXi5 (Update1 Build) to an Debian 6 LIO Target (Git commit e163b66985fa162bd7c1e29a049b336bc2790a2e). The Esxi Server is single FC connected to Lio (P2P).. Lio-Target serves n 100 GB LVM Disk via iblock to the ESXi. I started installing an Windows 7 VM on this Datastore (VMFS 5.54) "Strong as a LIO-N" gives me a lot of Errors in dmesg: [ 1146.241497] MODE SENSE: unimplemented page/subpage: 0x1c/0x02 [ 1231.742035] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1231.753493] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1231.765680] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1300.303536] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1300.308241] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1300.312904] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1313.008761] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1313.013449] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1313.018111] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1316.343687] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1316.348386] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1316.353041] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1320.468975] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1320.473646] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation [ 1320.478306] WRITE_SAME w/o UNMAP bit not supported for Block Discard Emulation ...
