(see question marks
in table above, what is the resulting mode?).
What I would like to do is enable compression on all OSDs, enable compression
on all data pools and disable compression on all meta data pools. Data and meta
data pools might share OSDs in the future. The above ta
tore_compressed_original=0.04 or
bluestore_compressed_allocated/bluestore_compressed_original=0.5? The second
ratio does not look too impressive given the file contents.

Hello,
i'm facing a problem that mds seems not to start.
I started mds in debug mode "ceph-mds -f -i storage08 --debug_mds 10" which
outputs in the log:
-- cut -
2015-09-21 14:12:14.313534 7ff47983d780 0 ceph version 0.94.3

If you don't need LACP you could use round-robin bonding mode.
With 4x1Gbit NICs you can get a bandwidth of 4Gbit per TCP connection.
Either create trunks on stacked switches (e.g. Avaya) or use single

The latter is some

It's absence is currently causing great amounts of consternation in a
discussion about using and deploying Ceph in an environment I deal with and
