Description
===========
Usage: ceph-disk prepare --cluster [cluster-name] --cluster-uuid [uuid] --fs-type
[ext4|xfs|btrfs] [data-path] [journal-path]
-**activate**: Activate the ceph OSD. It mounts the volume in a temporary location,
-allocates an OSD id (if needed), remounts in the correct location /var/lib/ceph/
-osd/$cluster-$id and starts ceph-osd. It is triggered by udev when it sees the OSD
-GPT partition type or on ceph service start with 'ceph disk activate-all'. It is
-also run directly or triggered by **ceph-deploy**.
+Other options like --osd-uuid, --journal-uuid, --zap-disk, --data-dir, --data-dev,
+--journal-file, --journal-dev, --dmcrypt and --dmcrypt-key-dir can also be used
+with the subcommand.

+/var/lib/ceph/osd/$cluster-$id and starts ceph-osd. It is triggered by udev
+when it sees the OSD GPT partition type or on ceph service start with
+'ceph disk activate-all'. It is also run directly or triggered by **ceph-deploy**.
+
+Usage: ceph-disk activate [PATH]
+
+Here, [PATH] is path to block device or directory.
An additional option [--activate-key PATH] has to be used with this subcommand
when a copy of /var/lib/ceph/bootstrap-osd/{cluster}.keyring isn't present in the
OSD node.
-Usage: ceph-disk activate [data-path] [--activate-key PATH]
+Usage: ceph-disk activate [PATH] [--activate-key PATH]
+
+Another option --mark-init can also be used with this subcommand.
**activate-journal**: Activate an OSD via it's journal device. udev triggers
'ceph-disk activate-journal <dev>' based on the partition type.
**activate-all**: Activate all tagged OSD partitions. activate-all relies on
/dev/disk/by-parttype-uuid/$typeuuid.$uuid to find all partitions. Special udev
-rules is installed to create these links. It is triggered on ceph service start
-up or run directly.
+rules are installed to create these links. It is triggered on ceph service start
+or run directly.
Usage: ceph-disk activate-all
+Others options can also be used with this subcommand like --activate-key and
+--mark-init.
+
+Usage: ceph-disk activate-all [--activate-key PATH] [--mark-init INITSYSTEM]
+
**list**: List disk partitions and ceph OSDs. It is run directly or triggered
by **ceph-deploy**.
Usage: ceph-disk list
**suppress-activate**: Suppress activate on a device (prefix).
+Mark devices that you want to suppress activate with a file like
+/var/lib/ceph/tmp/suppress-activate.sdb where the last bit is
+the sanitized device name (/dev/X without the /dev/ prefix). A
+function is_suppressed() checks for and matches a prefix (/dev/).
+It means suppressing sdb will stop activate on sdb1, sdb2, etc.
Usage: ceph-disk suppress-activate [PATH]
Here, [PATH] is path to block device or directory.
-**zap**: Zap/erase/destroy a device's partition table and contents. It is
-also run directly or triggered by **ceph-deploy**.
+**zap**: Zap/erase/destroy a device's partition table and contents.
+It actually uses 'sgdisk' and it's option '--zap-all' to destroy both
+GPT and MBR data structures so that the disk becomes suitable for
+repartitioning. 'sgdisk' then uses '--mbrtogpt' to convert the MBR or
+BSD disklabel disk to a GPT disk. The **prepare** subcommand can now be
+executed which will create a new GPT partition. It is also run directly
+or triggered by **ceph-deploy**.
Usage: ceph-disk zap [DEV]
