I am getting a SSD and need to know, does Linux support TRIM if I set up LVM on top of the SSD? I'm finding conflicting information. I'm currently running Ubuntu 10.10 with kernel 2.6.35-28.

This question came from our site for system and network administrators.

Trim support was added for LVM in the 2.6.37 kernel (source). However, combining LVM and RAID does not currently support TRIM.

According to this ServerFault question, TRIM works correctly through ext4+LVM+mdraid as of Linux 2.6.38. (thanks to this post)

Until the Kernel Version 2.6.33 the TRIM command in inserted to the kernel.

Here are some information.
