I've just installed kernel 5.6.7-3, latest systemd 245.5, updated glibc and grub2 and am getting a strange message that I've never seen before.

It also shows up when I'm root.

Wanted to try xfs_repair and since I don't know what I'm doing, this is what I got.

[root@dellirium ~]# xfs_repair /dev/sda1
xfs_repair: /dev/sda1 contains a mounted filesystem
xfs_repair: /dev/sda1 contains a mounted and writable filesystem

fatal error -- couldn't initialize XFS library

[root@dellirium ~]# mount | grep sda
/dev/sda1 on / type xfs (rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)
/dev/sda6 on /home type xfs (rw,relatime,attr2,inode64,logbufs=8,logbsize=32k,noquota)
