Unable to mount tape on a Quantum ULTRIUM-HH8 #383

Closed black-inc-service closed 1 year ago

black-inc-service commented 1 year ago

Describe the bug I have LTO-7 tape which has been formatted to type M to get 9TB of capacity using xTalk from quantum. mkltfs of a tape is successful (has a few errors in log?) but unable to mount.

To Reproduce Steps to reproduce the behaviour:

  1. mkltfs -d /dev/sg0 -f
  2. ltfs -o devname=/dev/sg0 /mnt/ltfs

Hardware:

mkltfs -d /dev/sg0 -f

Thanks for your help that got it working. It would be nice to have supported HBAs and/or a link to the FAQ in the main readme.
