  • Please copy and paste your plain text outputs and configurations as text and not images or "screenshots". I looked at your screenshots, and I don't see any mention of `/dev/sdb`, can you include output from `lsblk`? – Matt Kereczman Mar 17 '22 at 23:27

  • I would add things like that to your question, so it doesn't lose formatting like it does in the comments. Either way, I don't see `/dev/sdb` in any of that output, which is the block device you're trying to use as DRBD's backing device in the configuration. – Matt Kereczman Mar 21 '22 at 19:51
