Is this expected? File system continues to work OK, sha256sum on the
single file on this fs matches the source, but the metadata corruption
messages are a bit scary so figured I'd ask about it.
Filesystem created with
xfsprogs-4.3.0-1.fc23
kernel-4.4.4-300.fc23.x86_64
mkfs.xfs defaults used on an LVM thinly provisioned volume on a single
spinning disk.

Mounted the file system, copied one decently large ISO, deleted it,
unmounted the file system. Upgraded to kernel 4.5.0, and
xfsprogs-4.3.0-3.fc23, reboot, mounted the file system again, copied a
file, unmounted, and then tried to rename its label:
[root@f23s ~]# xfs_admin -L testxfs /dev/mapper/VG-testxfs
Metadata corruption detected at xfs_agf block 0x30d3808/0x1000
xfs_admin: cannot init perag data (-117). Continuing anyway.
writing all SBs
new label = "testxfs"
