Re: mount /dev/rbd0 /mnt/image2 + rm Python-2.7.13 -rf => freeze

[Stéphane Klein <contact@xxxxxxxxxxxxxxxxxxx>]

No problem with Debian:

```
root@ceph-client-2:/mnt/image2# rbd --version
ceph version 10.2.5 (c461ee19ecbc0c5c330aca20f7392c9a00730367)
root@ceph-client-2:/mnt/image2# uname --all
Linux ceph-client-2 3.16.0-4-amd64 #1 SMP Debian 3.16.7-ckt9-2 (2015-04-13) x86_64 GNU/Linux
```

I need to upgrade rbd on AtomicProject.

Hi,

I use this Ansible installation: https://github.com/harobed/poc-ceph-ansible/tree/master/vagrant-3mons-3osd

I have:

* 3 osd

* 3 mons

```
root@ceph-test-1:/home/vagrant# ceph version
ceph version 10.2.5 (c461ee19ecbc0c5c330aca20f7392c9a00730367)
```

```
bash-4.2# rbd --version
ceph version 0.80.7 (6c0127fcb58008793d3c8b62d925bc91963672a3)

```

```
# uname --all
Linux ceph-client-1 3.10.0-327.36.1.el7.x86_64 #1 SMP Sun Sep 18 13:04:29 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux
```

What I do to freeze rbd mounted folder:

```
$ vagrant ssh ceph-client-1
$ sudo su
# rbd map rbd/image2 --id admin
# mkdir -p /mnt/image2
# mount /dev/rbd0 /mnt/image2
# cd /mnt/image2/
# curl https://www.python.org/ftp/python/2.7.13/Python-2.7.13.tar.xz -o Python-2.7.13.tar.xz
# tar xf Python-2.7.13.tar.xz

# rm Python-2.7.13 -rf
rm ^C^C^C^C^C^C^C^C^C^C

```

here, nothing, I can't kill "rm" process.

What can I do? How can I debug that?

Best regards,

Stéphane
