Hi.. I have an OCZ agility SSD drive with FW 1.5 that supports the TRIM command. I can see that ext4 mounted with the "discard" option issues the TRIM command successfully when I use a plain partition to host the filesystem. But it does not seem to work together with LVM, and I'm guessing that it's DM that actually is the problem here since LVM is more like a admin interface to DM right? According to a response [1] I got on the ext4 ML it is expected behaviour right now, my question is whether this is something that is planned to be supported through DM? 1. http://www.spinics.net/lists/linux-ext4/msg17842.html If it is being worked on, then of course it's interesting to get an idea of how far in the future can be expected to work? Otherwise I guess that I will consider reverting back to plain partitions on my SSD drive.
