[PATCH 00/19] ceph distributed file system client

From: Sage Weil
Date: Wed Aug 05 2009 - 18:32:56 EST


Hi,

This is v0.12 of the Ceph distributed file system client. Changes since
v0.11 include:

- mapping_set_error on failed writepage
- document correct debugfs mount point
- simplified layout/striping ioctls
- removed bad kmalloc in writepages
- use mempools for writeback allocations where appropriate (*)
- fixed a problem with capability, snap metadata writeback
- cleaned up f(data)sync wrt metadata writeback

(*) There are still some OOM possibilities on writeback in the
messenger library. It's possible to avoid this with the careful use
of mempools, but I'd like to avoid doing so until it's clear the
protocol isn't going to change further.

The client seems to be quite stable in a single mds, no snapshot
scenario (including recovery from mds, osd restarts). Thorough
testing of snapshots and multiple MDSs is coming next. Client
authentication (beyond the current host ip checking) is the other main
item on the client todo list.

As always, I'm very interested in hearing what people would like to
see for this to be merged.

Thanks,
sage
