[Rdo-list] Notes for setting up NFS share to store nova instances
Heya,
I just saw a question on RDO forum related to $subject. Just posting some notes here, as
this was in my drafts anyhow. (Will point a link to this on the Forum. Also, thanks to
Giulio Fidente for reminding me on the qemu.conf bit below).
NFS share to store nova instances
---------------------------------
If you have an NFS share to store images, you could add it the below
way. The default location where instances are stored --
`/var/lib/nova/instances`
First, on the NFS server side :
$ cat /etc/exports
/home/kashyap *(rw,syn,no_root_squash)
Mount an nfs share w/ nova specific SELinux context :
$ mount --verbose -t nfs xx.yy.www.zzz:/home/kashyap \
/mnt -o "context=unconfined_u:object_r:nova_var_lib_t:s0"
# Set correct permissions on mount point
$ chown -R nova: /mnt/nova/
$ chgrp -R qemu /mnt/nova/instances/
$ chmod -R g+w /mnt/nova/instances
Ensure to have nova own the QEMU instances invoked by :
$ grep nova /etc/libvirt/qemu.conf
user = "nova"
group = "nova"
Restart all 'running' OpenStack services :
$ for j in `for i in $(ls -1 /etc/init.d/openstack-*) ; \
do $i status | grep running ; done | awk '{print $1}'`; \
do service $j restart ; done
Later, ensure, your instances are indeed owned by nova ::
$ ps -ef | grep -i qemu-kvm | grep -i nova
--
/kashyap
