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.
Tell me more

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. |
