I didn't mention that my LVM volumes are thin volumes. They use a shared storage pool, with other thin volumes, and when an area is trimmed, the areas are released back to the storage pool. As a test, I got "fstrim" to work eliminating LVM, just using it on a raw partition with NTFS. I think this means ntfs-3g isn't recognizing its underlying device (LVM thin) supports trim/discard. Again, when btrfs receives a "fstrim" request, and is also on a thin LVM volume, it is able to detect it can send a trim/discard to it. _______________________________________________ ntfs-3g-devel mailing list ntfs-3g-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/ntfs-3g-devel
