XFS reflinks enable not recognized

[KeiichiKun]

Hi all,
I've made a XFS repository on ubuntu 21.04 with these parameters

mkfs.xfs -b size=4096 -m reflink=1,crc=1 /dev/sdb
mount /dev/sdb /backup1
mkdir /backup1/backups
chmod -R myuser: /backup1/backups

When I create the linux immutable xfs with fast cloning repository I got the error ""File system behind the provided path has XFS reflinks disabled: /backup1/backups".

Any hint? Thanks!

Hello KeiichiKun,

Ubuntu 21.04 is quite new release and is not yet supported for XFS backup repositories. If at all possible, we will add support for it down the road.

Cheers!

I thought it might be the cause, but hoped not. Instead that was the cause, I installed ubuntu 20.04 and everything works fine!
Thanks

It is best practice to use only LTS releases for proxies/repositories unless you really enjoy experiencing constant breakage due to forced upgrades since non-LTS releases are only supported for 9 months by Ubuntu.
