Wat het doet

XFS is fast with large files and many parallel writers. It can grow while mounted (xfs_growfs) but can not be shrunk. The defaults are good for nearly all cases; the label (-L, max 12 characters) is the option you use most.

1Create XFS
```
#mkfs.xfs /dev/vdb1
```
Prints the geometry it chose.
2With a label
```
#mkfs.xfs -L data /dev/vdb1
```
Mount with LABEL=data.
3Overwrite an old file system
```
#mkfs.xfs -f /dev/vdb1
```
Without -f it refuses when it finds a file system.
4On a logical volume
```
#mkfs.xfs /dev/vgdata/lvdata
```
Grow later with lvextend -r.
5Show settings without creating
```
#mkfs.xfs -N /dev/vdb1
```
Dry run.
6Fast creation on a thin or SSD device
```
#mkfs.xfs -K /dev/vdb1
```
Skips the discard step (faster on big devices).
7For a RAID with stripe settings
```
#mkfs.xfs -d su=64k,sw=4 /dev/md0
```
Aligns with the RAID layout.
8Check the result
```
#xfs_info /dev/vdb1
```
After mounting, use the mount point.
9Set the label later
```
#xfs_admin -L newname /dev/vdb1
```
Only when not mounted.
10Remember: no shrinking
```
#xfs_growfs /data
```
XFS grows only. Plan sizes; use ext4 when you may need to shrink.
