Subject: Question about using reflink and realtime features on the same filesystem

Message-ID: <0101018ee939dd0d-f4f89d16-04ff-44ae-97f6-541a30117a4d-000000@us-west-2.amazonses.com> (raw)
Greetings,
I was attempting to use mkfs.xfs on Linux Mint 21 (kernel 6.5.0, xfsprogs 5.13.0) and ran into an
error trying to use realtime and reflink features on the same filesystem. Is there anything I'm
doing wrong, or is this combination simply not supported on the same filesystem?
The exact command I ran was:
mkfs.xfs -N -r rtdev=/dev/sda1,extsize=1048576 -m reflink=1 /dev/sda2
Which returned with:
reflink not supported with realtime devices
Just to be clear - I didn't expect to be able to use reflinking on realtime files (*), but I did
expect to be able to have realtime files and reflinked non-realtime files supported on the same
filesystem. With my limited knowledge of the inner workings of XFS, those two features _seem_ like
they could both work together as long as they are used on different inodes. Is this not the case?
Thanks,
Reed Wilson
(*) I noticed that there were recent commits for reflinking realtime files, but that's not really
what I was looking for
