I have an xfs filesystem that has some free space. Can I shrink it? I know of xfs_growfs. And there is resize2fs and resize_reiserfs.

Side question: is xfs not a good filesystem choice for bulk longterm file storage?

You can make a backup, and then create a new smaller file system and restore.

XFS cannot be shrunk (ref).

    +1 - there were some patches adding support for shrinking a filesystem, but they seem to have stalled now

    For RedHat (and CentOS) users, see RedHat's article 540013.

    Some documentation about XFS backup/dump/restore XFS Dump and Restore, and Red Hat 6 documentation

    @FranklinPiat, that Red Hat article requires a subscription for access.
