After getting all the OSDs and MONs updated and running ok, I updated the
MDS as usual; rebooted the machine after updating the kernel (we're on

Supposedly cephfs-hadoop worked and/or works on hadoop 2. I am in the
process of getting it working with cdh5.7.0 (based on hadoop 2.6.0).
I'm under the impression that it is/was working with 2.4.0 at some

I think what you are thinking of is the driver that was built to actually
replace hdfs with rbd. As far as I know that thing had a very short
lifespan on one version of hadoop. Very sad.

Please try:
ceph pg repair 4.97
And look if it can be resolved.
If not, please paste the corresponding log.
That repair can take some time...

Hi Guys,
I am new to ceph and have a openstack deployment that uses ceph as the
backend storage. Recently we had a failed OSD disk which seems to have
caused issues for any new volume creation. I am really surprised that
having a single osd drive down or node down could cause such a large
impact

Hi,
there is a memory allocation bug, at least in hammer.
Mouting an rbd volume as a block device on a ceph node might run you
