This page documents the Alpine Linux supported filesystems needed for various storage media.
Overview
The following table lists the packages and tools related to various filesystems available along with the command to format.
| Tool | Filesystem | Formatting command | Brief Notes |
| btrfs-progs | Btrfs | mkfs.btrfs | Combines copy-on-write and volume management, similar to ZFS. |
| dosfstools | FAT12/FAT16/FAT32 | mkfs.vfat | Widely-used DOS filesystems. Also used for EFI partitions. |
| e2fsprogs | ext2/ext3/ext4 | mkfs.ext4 | Journaling filesystems. ext4 is the current default on Linux. |
| exfatprogs | exfat | mkfs.exfat | Commonly used on USB flash drives and SD cards. |
| f2fs-tools | F2FS | mkfs.f2fs | |
| hfsprogs | HFS/HFS+ | mkfs.hfsplus | Used in older Apple/Mac products before APFS. |
| jfsutils | JFS | mkfs.jfs | |
| ntfs-3g-progs | NTFS | mkfs.ntfs | Full-featured, Microsoft/Windows FUSE driver. |
| squashfs-tools | SquashFS | mksquashfs | Compressed read-only file system. |
| xfsprogs | XFS | mkfs.xfs |
Additionally, Alpine has excellent support for ZFS, a highly robust copy-on-write filesystem / volume manager.
Filesystem labels
Most of the commonly used filesystems store the volume label or filesystem label in their metadata/superblock.
Labels can be set during filesystem creation or at a later time. The below table lists the commands for both. The commands are non-destructive as long as the filesystem is Unmounted, except for btrfs.
| Filesystem | Tool | Filesystem creation | Existing filesystem | Mounted/Unmounted |
| btrfs | btrfs-progs | mkfs.btrfs -L "label" /dev/sdXY | btrfs filesystem label /mount/point "newlabel" | Mounted |
| FAT32 | dosfstools | mkfs.fat -n "LABEL" /dev/sdXY | fatlabel /dev/sdXY "NEWLABEL" | Unmounted |
| ext4 | e2fsprogs-extra | mkfs.ext4 -L "label" /dev/sdXY | tune2fs -L "newlabel" /dev/sdXY | Unmounted |
| NTFS | ntfs-3g-progs | mkfs.ntfs -L "label" /dev/sdXY | ntfslabel /dev/sdXY "newlabel" | Unmounted |
| XFS | xfsprogs | mkfs.xfs -L "label" /dev/sdXY | xfs_admin -L "newlabel" /dev/sdXY | Unmounted |
