Hi all,
I've just attempted to add a new node and OSD to an existing ceph cluster (it's
a small one I use as a NAS at home, not like the big production ones I normally
work on) and it seems to be throwing some odd errors...
Just looking for where to poke it next...

Hi,
you need to set the max dirty bytes and/or max dirty objects as these 2
parameters will default to 0 for your cache pool.

The ratios you already set (dirty_ratio = 0.4 and
Can you reproduce this with
debug osd = 20
debug filestore = 20
debug ms = 1
on the crashing osd? Also, what sha1 are the other osds and mons running?

EPEL is required for the libunwind library.
If libunwind is copied to the ceph repo then EPEL would not be required.

The option --dmcrypt-key-dir when you want to activate/create a new

/etc/ceph/dmcrypt-keys/ is hard coded in udev rules.
I have found and test two simple way to solve :
- Change the path of keys in ''/lib/udev/rules.d/95-ceph-osd.rules''
what is going on with ceph?

It may be safer to make the change incrementally rather than all at once. Since
