I've found out that xfs file system type is default for RHEL7.

  1. Is there any known issues with that fs?
  2. How can it affect performance?
  3. Is there a way to move back to ext?

BTW, after moving from RHEL6 to 7, I've faced memory fragmentation. See here for details.

    I'm not aware of any issues, but performance wise XFS handles concurrent writes a bit more efficiently than ext4. As for moving back to ext, the only way I know how is to reinstall from scratch and pick ext3/4. – pacmanwa May 24 '18 at 15:12
  • Thanks for your comment @pacmanwa. I'll take it into consideration. – sys463 May 24 '18 at 15:21
