[opensuse] Is there a fstrim like tool that punches holes? Would it work with a NFS mount?
by Greg Freemyer 02 Aug '15

All, Due to an Admin screw up: (and yes I'm the admin). I have a large loopback mounted filesystem with about 100GB of unused space. I need to punch holes where the unused space is and free up some disk space. That is where fstrim calls ioctl(FITRIM) to free up space on a SSD I need something that calls fallocate(FALLOC_FL_PUNCH_HOLE) to free up space on an underlying filesystem If nothing already exists to do this I guess I could hack on fstrim and get it to do if for me. The next issue is my underlying filesystem is a NFS mount. Not sure if will handle fallocate(FALLOC_FL_PUNCH_HOLE). Worst case I guess I can grow the NFS mount, but I rent that space monthly, so I'd rather not have to grow it by 100GB to fix my issue.
