Supported Features of Kernel Driver
|
||
|
|
========================================
|
||
|
|
|
||
|
|
Inline data
|
||
|
|
-----------
|
||
|
|
Inline data was introduced by the Firefly release. Linux kernel clients >= 3.19
|
||
|
|
can read inline data, can convert existing inline data to RADOS objects when
|
||
|
|
file data is modified. At present, Linux kernel clients do not store file data
|
||
|
|
as inline data.
|
||
|
|
|
||
|
|
See `Experimental Features`_ for more information.
|
||
|
|
|
||
|
|
Quotas
|
||
|
|
------
|
||
|
|
Quota was first introduced by the hammer release. Quota disk format got renewed
|
||
|
|
by the Mimic release. Linux kernel clients >= 4.17 can support the new format
|
||
|
|
quota. At present, no Linux kernel client support the old format quota.
|
||
|
|
|
||
|
|
See `Quotas`_ for more information.
|
||
|
|
|
||
|
|
Multiple filesystems within a Ceph cluster
|
||
|
|
------------------------------------------
|
||
|
|
The feature was introduced by the Jewel release. Linux kernel clients >= 4.7
|
||
|
|
can support it.
|
||
|
|
|
||
|
|
See `Experimental Features`_ for more information.
|
||
|
|
|
||
|
|
Multiple active metadata servers
|
||
|
|
--------------------------------
|
||
|
|
The feature has been supported since the Luminous release. It is recommended to
|
||
|
|
use Linux kernel clients >= 4.14 when there are multiple active MDS.
|
||
|
|
|
||
|
|
Snapshots
|
||
|
|
---------
|
||
|
|
The feature has been supported since the Mimic release. It is recommended to
|
||
|
|
use Linux kernel clients >= 4.17 if snapshot is used.
