  • off-topic. changing the filesystem must always be a done via recreation of the filesystem. So backup, format and recovery is always the point. Questions should demonstrate reasonable information technology management practices. Questions that relate to unsupported hardware or software platforms or unmaintained environments may not be suitable for Server Fault. – djdomi Jan 01 '22 at 11:04

  1. Make a backup
  2. unmount the disk/partition/volume
  3. format the disk/partition/volume with mkfs.xfs
  4. restore the data from backup.
