[lxc-users] What are the options for connecting to storage?

[McDonagh, Ed]

Thanks Ron. Thinking my requirements through again, I’ve decided to scrap the iSCSI mount and use NFS/CIFS instead. So following your pointer I have NFS mounted in the host, and then bind-mounted that to the container. I’ve yet to see how that migrates, but one bridge at a time!

Thanks again.

Kind regards

Ed

What about using a bind-mount?  Mount your iscsi volume to the LXD server and bind-mount it into the container.  A quick URL:  https://github.com/lxc/lxd/issues/2005

Hi

I need to create a container that has access to a couple of TB to store image files (mostly 8MB upwards). My instinct is to create an iSCSI target on my Synology server and connect from the container to get a new disk that I can use for the storage.

I understand that the guest has to be privileged to do any sort of connection to storage, however it seems that the iSCSI node in the container doesn’t work.

What are my options? Do I need to use a SMB connection to the Synology server? Or is NFS better? Is there a way to connect using iSCSI?

If it makes any difference, I have two identical servers that I am running LXD on, and want to be able to move the containers between them for maintenance etc. Ideally live, but not essential. And that doesn’t seem to work anyway with lxd 2.0, so kind of a moot point!

Any help, suggestions or advice would be very welcome.

Kind regards

Ed
