The node kernel may not support all options set during the mkfs.xfs command (from the csi driver image). This leads to problem when mounting the file system with incompatible features/options.
Expected behavior
To make sure the created XFS file system work on a known set of linux kernels, we might want to configure a set of options compatible with those node kernels.
For example, we want to support linux kernels >= 5.15, we can do the following:
$ cat /usr/share/xfsprogs/mkfs/lts_5.15.conf
# V5 features that were the mkfs defaults when the upstream Linux 5.15 LTS
# kernel was released at the end of 2021.
