I have bunch of XEN virtual machines.
I want to share few partitions that are on different drive.
At first I was thinking of using "disk" variables in configuration file, but xen manual states:
disk - List of block devices to export to the domain e.g. disk = [ 'phy:hda1,sda1,r' ] exports physical device /dev/hda1 to the domain as /dev/sda1 with read-only access. Exporting a disk read-write which is currently mounted is dangerous - if you are certain you wish to do this, you can specify w! as the mode.
Other option would set NFS server on Xen host and mount share from guest.
Which of the options is better?
Is it ok to store MySQL files on NFS share?
