Hi, I have set-up of server with 4 SSDs (OCZ Vertex 2) stripped using LVM. Logical volume has been created using the -i 4 option (iostat confirms that the 4 disks work in parallel when I write a file). Ext4 fs is used on the volume, mounted with -discard option. I am using kernel 2.6.38. My question is : is there a chance that TRIM command makes its way to the disks through LVM ? I've read contradictory informations on the web and I'm sure this is the best place to ask. My second question is : how would I make _sure_ it works ? I've found a way to do it with hdparm --fibmap and hdparm --read-sector here http://askubuntu.com/questions/18903/how-to-enable-trim But I don't think this can work with LVM. Would there be a similar way to make sure it is working while using LVM ? Thanks a lot, Franck _______________________________________________ linux-lvm mailing list linux-lvm@redhat.com https://www.redhat.com/mailman/listinfo/linux-lvm read the LVM HOW-TO at http://tldp.org/HOWTO/LVM-HOWTO/
