Question about ftype

Question about ftype

[Iustin Pop]

Hi all,

I recently saw that a newly created filesystem has ftype=1. Reading the
man pages of mkfs.xfs and xfs_admin/xfs_db and not finding anything
about changing ftype (xfsprogs 3.2.4) leads me to believe that this
feature can only be set at mkfs time, but could someone confirm if it is
indeed so?

thanks,
iustin

That is correct - it is an on-disk format change, and can only be set
at mkfs time.

It was enabled by default (along with metadata CRCs) in xfsprogs v3.2.3
