Hi Steffen,Sorry there was A mistake in my reply. The Unify schedulers cannot schedulebased on whether a sub-volume is read-only or not. Hence when a new file creation operation comes, the scheduler _cannot_ neglect the read-only subvolumes for creating the file. There is a fairly good chance that thefile creation operation be scheduled on a read-only subvolume which ofcoursewill fail.How does the scheduler handle the case when disk-min-free (cant remember the option exactly) condition is met. I had a feeling if there was less than so much free space left on a sub-volume, it skipped it for writing new files.In the case of a read-only volume, wouldn't the free space = 0MB, meeting the condition of the free space parameter.Unless of course I have it wrong totally :) (i cant check on the site at the moment, its unreachable :/)Matt.
