Hi, I have couple of questions in deploying ephemeral storage.
How can I change the disk partition (or directory) that the compute nodes use for the ephemeral storage? I have HDD and SSD. I want to differentiate them.
Can I make the different kinds of the ephemeral storage as available resources? An instance may be attached to eph1 (type A) and the other to eph2 (type B).
thanks for your help,
Attempt to address 1
1. Create partition like /dev/sdb1 with xfs FS ( via gparted )
2. Add to /etc/fstab
/dev/sdb1 /var/lib/nova/instances xfs defaults 0 0
3. # mount -a
4. Next
# chown nova /var/lib/nova/instances/
# chgrp nova /var/lib/nova/instances
Works for me
[root@ServerCentOS02 ~(keystone_boris)]# nova list

Update libvirt xml is possible only via changing python code in nova/virt/libvirt/driver.py and nova/virt/libvirt/config.py
