I am trying to set up a CephFS with a Cache Tier (for data) on a mini test
cluster, but a kernel-mount CephFS client is unable to write. Cache tier
setup alone seems to be working fine (I tested it with `rados put` and `osd

Please disregard the earlier message. I found the culprit:
`osd_crush_update_on_start` was set to false.

I am trying to build a Ceph cluster using ceph-deploy. To add OSDs, I used
the following command (which I had successfully used before to build
another cluster):
ceph-deploy osd create --block-db=ssd0/db0 --data=/dev/sdh osd0
ceph-deploy osd create --block-db=ssd0/db1 --data=/dev/sdi osd0
I followed the documentation (http://docs.ceph.com/docs/mimic/mgr/dashboard/)
to enable the dashboard RGW management, but am still getting the 501 error
("Please consult the documentation on how to configure and enable the
Object Gateway... "). The dashboard it self is working.
1. create a RGW
I would like to know the simplest and surest way to set up a RGW instance
with an EC-pool for storing large quantity of data.
1. I am currently trying to do this on a cluster that is not yet open to
users. (i.e. I can mess around with it and, in the worst case, start all
over.)
2. I deployed RGW
ode, I will go back to the previous node and see if I can zap it and start
all over again.

nnot restart any of these 10 daemons (`systemctl start ceph-osd@6
[0-9]`).
I am wondering if I should zap these 10 osds and start over although at
this point I am afraid even zapping may not be a simple task

(Should it be?) Neither does mount lists that drive. ("df | grep sdh"
and "mount | grep sdh" both return nothing)

encounter any errors. I am planning on trying to start the OSDs (once they
are converted to Bluestore) without the udev rule first.

Yes, I still have the volume log showing the activation process for
ssd0/db60 (and 61-69 as well). I will email it to you directly as an
attachment.

I already ran the "ceph-volume lvm activate --all " command right after I
prepared (using "lvm prepare") those OSDs. Do I need to run the "activate"
command again?

I did find in /etc/fstab entries like this for those 10 disks

Should I comment all 10 of them out (for osd.{60-69}) and try rebooting
again?

the "ln" command (basically getting
rid of the symbolic link) for each of those OSDs I have converted? For
example
ln -sf /dev/null /etc/systemc/system/ceph-disk@60.service
Then reboot?

Additional info -- I know that /var/lib/ceph/osd/ceph-{60..69} are not
mounted at this point (i.e. mount | grep ceph-60, and 61-69, returns
nothing.). They don't show up when I run "df", either.

I see this for every single one of the newly-converted Bluestore OSD disks
(/dev/sd{h..q}1).

As a Ceph novice, I am totally clueless about the next step at this point.
Any help would be appreciated.

I am relatively new to Ceph and need some advice on Bluestore migration. I
tried migrating a few of our test cluster nodes from Filestore to Bluestore
by following this (
