cdist-type__filesystem(7)
=========================
NAME
----
cdist-type__filesystem - Create Filesystems.
DESCRIPTION
-----------
This cdist type allows you to create filesystems on devices.
If the device is mounted on target, it refuses to do someting.
If the device has a filesystem other as the specified and/or
the label is not correct, it only make a new filesystem
if you specified --force option
REQUIRED PARAMETERS
-------------------
fstype
Filesystem type, for example 'ext3', 'btrfs' or 'xfs'
blkdev
Blockdevice for filesystem,
On linux, it can be any by lsblk accepted device notation
for example
/dev/sdx
or /dev/disk/by-xxxx/xxx
or /dev/mapper/xxxx
OPTIONAL PARAMETERS
-------------------
label
Label which sould apply on the filesystem
mkfsoptions
Additional options which are inserted to the mkfs.xxx call.
BOOLEAN PARAMETERS
------------------
force
Normaly, this type does nothing if a filesystem is found
on the target device. If you specify force, its formated
if the filesystem type or label differs from parameters
Warning: This option can easy lead into data loss !
MESSAGES
--------
filesystem <fstype> on <blkdev> : <discoverd device> created
Filesytem was created on <discoverd device>
EXAMPLES
--------
.. code-block:: sh
# Ensures that device /dev/sdb is formated with xfs
__filesystem dev_sdb --fstype xfs --blkdev /dev/sdb --label Testdisk1
# The same thing with btrfs and disk spezified by pci path to disk 1:0 on vmware
__filesystem dev_sdb --fstype btrfs --blkdev /dev/disk/by-path/pci-0000:0b:00.0-scsi-0:0:0:0 --label Testdisk2
# Make sure that a multipath san device has a filesystem ...
__filesystem dev_sdb --fstype xfs --blkdev /dev/mapper/360060e80432f560050202f22000023ff --label Testdisk3
