Public bug reported: This issue is reproducible on two different nodes in our testpool, fozzie and rizzo, both with 4.4.0-98-generic amd64.
On a clean install system with a scratch drive sdb available. Steps: 1. sudo parted /dev/sdb mklabel -s gpt 2. sudo parted /dev/sdb mkpart -s p1 xfs 1MiB 20000MiB 3. sudo parted /dev/sdb mkpart -s p2 xfs 20001MiB 40000MiB 4. sudo mkfs.xfs -f /dev/sdb1 5. sudo mkfs.xfs -f /dev/sdb2 Result: mkfs.xfs: cannot open /dev/sdb2: Device or resource busy In my test case, there are 5 partitions from sdb1 to sdb5, only sdb2 will fail with this. And this happens on both nodes.
