Re: Scrubbing a lot

[German Anders <ganders@xxxxxxxxxxxx>]

I've just upgrade to jewel, and the scrubbing seems to been corrected... but now I'm not able to map an rbd on a host (before I was able to), basically I'm getting this error msg:

rbd: sysfs write failed
rbd: map failed: (5) Input/output error

# rbd --cluster cephIB create host01 --size 102400 --pool cinder-volumes -k /etc/ceph/cephIB.client.cinder.keyring
# rbd --cluster cephIB map host01 --pool cinder-volumes -k /etc/ceph/cephIB.client.cinder.keyring
rbd: sysfs write failed
rbd: map failed: (5) Input/output error

Any ideas? on the /etc/ceph directory on the host I've:

​Thanks in advance,

That seems to be scrubbing pretty often.  Can you attach a config diff
from osd.4 (ceph daemon osd.4 config diff)?
