stratis command [subcommand] [arguments]

stratis is a local storage management tool providing ZFS/Btrfs-like features using Linux devicemapper and XFS. It simplifies storage management by abstracting pools of block devices that can be dynamically allocated to thin-provisioned XFS filesystems.
The stratisd daemon must be running before using stratis commands. Filesystems appear at /dev/stratis/pool_name/filesystem_name and support features like snapshots, thin provisioning, and pool expansion.

Mount manually:

$ mount /dev/stratis/pool_name/fs_name /mnt/target

$ /dev/stratis/pool/fs /mnt xfs defaults,x-systemd.requires=stratisd.service 0 0

Requires stratisd service running. Uses XFS exclusively; other filesystems not supported. Pool devices should be dedicated; partitions with existing data will be overwritten. Snapshots share space with source until modified.

Stratis was developed by Red Hat starting around 2017 to provide easy-to-use storage management for Linux. It was designed to deliver modern storage features without the complexity of LVM or the kernel integration requirements of Btrfs/ZFS. Stratis became available in Fedora 28 and RHEL 8.
