Re: cannot open /dev/xvdb: Input/output error

[Massimiliano Cuttini <max@xxxxxxxxxxxxx>]

I can see the error even if I easily run list-mapped:

# rbd-nbd list-mapped
/dev/nbd0
2017-06-25 18:49:11.761962 7fcdd9796e00 -1 asok(0x7fcde3f72810) AdminSocketConfigObs::init: failed: AdminSocket::bind_and_listen: failed to bind the UNIX domain socket to '/var/run/ceph/ceph-client.admin.asok': (17) File exists/dev/nbd1

/dev/nbd2
/dev/nbd3
/dev/nbd4
/dev/nbd5
/dev/nbd6
/dev/nbd7

This issue downgrade my expectation about Ceph readyness for production.
After 4 months of work and test, this just is a thorn in my side.

I see that the issue was already raised by
http://lists.ceph.com/pipermail/ceph-users-ceph.com/2016-July/011938.html

Joecyw, how do you solve this issue?
