I have now successfully gotten ZFS running on my octo-core powermac. It seems nice! I am so thrilled to be using a real file system with pool based storage.
Now here's the question...I am trying to now set up backups for my laptops to the ZFS pool using time machine. I have created a sparse image bundle for each of the laptops, copied it to the remote server running ZFS, used the hack to get mac os x to share out non-hfs volumes, and used the technique listed here http://www.jamesbadger.ca/2012/09/12/mountain-lion-time-machine-over-afp-auto-mount-edition/ to "bless" the images as the official time machine destinations for the individual laptops. However, I end up receiving an error message when I do the last step:
- Code: Select all
Destination does not support lock stealing. (error 45)
Is this an inherent problem to ZFS that HFS sparse bundles cannot be hosted on ZFS volumes? Or is it a current implementation problem? Is there a workaround? Does merely copying the sparsebundles to a ZFS volume invalidate them in some way, or is it that time machine backups cannot run to a ZFS destination over a network?
Any insights would be most welcome!
thanks,
Erico
