I welcome anyone with more CephFS experience to weigh in on this! :)

As an aside, we're also working to update the documentation to reflect the
best practices. See Ceph.com tracker for this at:

, 32 PGs total still
gives very close to 1 PG per OSD. Being that it's such a low utilization
pool, this is still sufficient.

On the page.. :) It does link out to jquery and jquery-ui, but all the
custom bits are embedded in the HTML.
Glad it's helpful :)

I'm also unsure about the cache tiering and how it could relate to the load

Thanks Michael, still no luck.
Letting the problematic OSD.10 down has no effect. Within

## For help identifying why memory usage was so high, please provide:
* ceph osd dump | grep pool
* ceph osd crush rule dump
Let us know if this helps... I know it looks extreme, but it's worked for
me in the past..

Ah, sorry... since they were set out manually, they'll need to be set in
manually..
for i in $(ceph osd tree | grep osd | awk '{print $3}'); do ceph osd in $i;
done

Since the status is 'Abandoned', it would appear that the fix has not been
merged into any release of OpenStack.

Wondering what
After sending my earlier email, I found another commit that was merged in
March:
https://review.openstack.org/#/c/59149/
Seems to follow a newer image handling technique that was being sought
which prevented the first patch from being merged in...

You may also want to check your 'min_size'... if it's 2, then you'll be
incomplete even with 1 complete copy.
ceph osd dump | grep pool
You can reduce the min size with the following syntax:
ceph osd pool set poolname min_size 1

seen show BTRFS slows drastically after only a
few hours with a high file count in the filesystem. Better to re-deploy now
than when you have data serving in production.

Journals will default to being on-disk with the OSD if there is nothing
specified on the ceph-deploy line. If you have a separate journal device,
then you should specify it per the original example syntax.

Seems that you may also need to tell CephFS to use the new pool instead of
the default..
After CephFS is mounted, run:
# cephfs /mnt/ceph set_layout -p 4

While clearly not optimal for long term flexibility, I've found that adding
my OSD's to fstab allows the OSDs to mount during boot, and they start
automatically when they're already mounted during boot.
Hope this helps until a permanent fix is available.

It's also good to note that the m500 has built in RAIN protection
(basically, diagonal parity at the nand level). Should be very good for
journal consistency.

actually, they're very inexpensive as far as SSD's go. The 960gb m500 can
be had on Amazon for $499 US on prime (as of yesterday anyway).
