Hi, I am struggling to back up using LTO hardware compression in linux (the drives and tapes have been tried in windows and work as expected). I am using Hp Storageworks 232 lto1 / 448 lto2 / 920 lto3 and 3000 lto5 and a HP DAT72 drive on Leap 42.1 all with the same problem I have tried mt with the datcompression option and it says it is on for all my drives I have tried mtst with the compression option which does nothing at all with no output Also my drives are /dev/st0 st1 st2 and st3 also listed as /dev/st*1 /dev/st*m and /dev/st*a A quick google say these are different modes. What are these modes? Is one to enable the hardware compression? I am able to write to tapes and restore using tar -cvWf /dev/st* /srv/mydata/something but it does not even allow the native tape capacity (e.g. lto3 is native 400gb and I can't even fit 350GB on this tape (even after mt -f /dev/st3 erase 1) I have gone through HP's manual and there is no information on hardware compression. Does anyone know how to use hardware compression on LTO drives in linux?
