doc: cleanup PendingReleaseNotes drop sections already in previous releases, keeping only Mimic sections and a new section header for items going post 12.2.2 Signed-off-by: Abhishek Lekshmanan <abhishek@suse.com>

13.0.0
------
* The RBD C API's rbd_discard method now enforces a maximum length of
2GB to match the C++ API's Image::discard method. This restriction
prevents overflow of the result code.
mds: support limiting cache by memory This introduces two config parameters: mds_cache_memory_limit: Sets the soft maximum of the cache to the given byte count. (Like mds_cache_size, this doesn't actually limit the maximum size of the cache. It just dictates the steady-state size.) mds_cache_reservation: This replaces mds_health_cache_threshold everywhere except the Beacon heartbeat sent to the mons. The idea here is to specify a reservation of memory (5% by default) for operations and the MDS tries to always maintain that reservation. So, the MDS will recall caps from clients when it begins dipping into its reservation of memory. mds_cache_size still limits the cache by Inode count but is now by-default 0 (i.e. unlimited). The new preferred way of specifying cache limits is by memory size. The default is 1GB.

* *CephFS*:
PendingReleaseNotes: add obsoleted mds commands Signed-off-by: Patrick Donnelly <pdonnell@redhat.com>
2017-10-02 00:32:12 +00:00
* Several "ceph mds" commands have been obsoleted and replaced
by equivalent "ceph fs" commands:
- mds dump -> fs dump
- mds getmap -> fs dump
- mds stop -> mds deactivate
- mds set_max_mds -> fs set max_mds
- mds set -> fs set
- mds cluster_down -> fs set cluster_down true
- mds cluster_up -> fs set cluster_down false
- mds add_data_pool -> fs add_data_pool
- mds remove_data_pool -> fs rm_data_pool
- mds rm_data_pool -> fs rm_data_pool

client: quit on failed remount during dentry invalidate test Fixes: http://tracker.ceph.com/issues/22269 Signed-off-by: Patrick Donnelly <pdonnell@redhat.com>
2017-11-28 23:01:32 +00:00
- *CephFS*:
* The CephFS client now catches failures to clear dentries during startup
and refuses to start as consistency and untrimmable cache issues may
develop. The new option client_die_on_failed_dentry_invalidate (default:
true) may be turned off to allow the client to proceed (dangerous!).
