I assume you are referring either to Tux3 specifically or COW filesystems in general, because you very much _can_ do any of those on any of the non-COW filesystems in the Linux kernel (I know from experience). Also, IIRC, it was mentioned somewhere that Tux3 keeps a small reserve of space on the volume for internal operations; and, I would assume that if that is the case, it reports the volume full when everything *except* that reserve of space is used, in which case rm, rmdir, and truncate should work fine when the volume is full.On 05/26/2015 12:03 PM, Pavel Machek wrote:We identified the following quality metrics for this algorithm: 1) Never fails to detect out of space in the front end. 2) Always fills a volume to 100% before reporting out of space. 3) Allows rm, rmdir and truncate even when a volume is full.This is definitely nonsense. You can not rm, rmdir and truncate when the volume is full. You will need a free space on disk to perform such operations. Do you know why?
