MinIO strongly recommends local :abbr:`JBOD (Just a Bunch of Disks)` arrays with
XFS-formatted disks for best performance. RAID or similar technologies do not
provide additional resilience or availability benefits when used with
distributed MinIO deployments, and typically reduce system performance.
Ensure all nodes in the |deployment| use the same type (NVMe, SSD, or HDD) of
drive with identical capacity (e.g. ``N`` TB) . MinIO does not distinguish drive
types and does not benefit from mixed storage types. Additionally. MinIO limits
the size used per disk to the smallest drive in the deployment. For example, if
the deployment has 15 10TB disks and 1 1TB disk, MinIO limits the per-disk
capacity to 1TB.
MinIO *requires* using expansion notation ``{x...y}`` to denote a sequential
series of disks when creating the new |deployment|, where all nodes in the
|deployment| have an identical set of mounted drives. MinIO also
requires that the ordering of physical disks remain constant across restarts,
such that a given mount point always points to the same formatted disk. MinIO
therefore **strongly recommends** using ``/etc/fstab`` or a similar file-based
mount configuration to ensure that drive ordering cannot change after a reboot.
For example:
.. code-block:: shell
$ mkfs.xfs /dev/sdb -L DISK1
$ mkfs.xfs /dev/sdc -L DISK2
$ mkfs.xfs /dev/sdd -L DISK3
$ mkfs.xfs /dev/sde -L DISK4
$ nano /etc/fstab
# <file system> <mount point> <type> <options> <dump> <pass>
LABEL=DISK1 /mnt/disk1 xfs defaults,noatime 0 2
LABEL=DISK2 /mnt/disk2 xfs defaults,noatime 0 2
LABEL=DISK3 /mnt/disk3 xfs defaults,noatime 0 2
LABEL=DISK4 /mnt/disk4 xfs defaults,noatime 0 2
You can then specify the entire range of disks using the expansion notation
``/mnt/disk{1...4}``. If you want to use a specific subfolder on each disk,
specify it as ``/mnt/disk{1...4}/minio``.
MinIO **does not** support arbitrary migration of a drive with existing MinIO
data to a new mount position, whether intentional or as the result of OS-level
behavior.
