Thanks. I tried that as well but it still doesn't work. Just to be sure I created a file with random data, read the sectors with hdparm and then removed the file and did a flush. If discard was active the sector should be zeroed out. It was however still there after a sync, and also after waiting an hour just in case. > If that doesn't do it maybe there's a bug here. It sounds like that. I took a look at the xfs source code in the kernel tree. It looks like the discard code is simply never called except for when there's an ioctl call. I guess that's what fstrim triggers. But from what I could see there's no realtime support in kernel right now. I guess I should go with ext4 for now.
