I have been trying to get my logical volume to be aligned to a 512 KB boundary on my SSD so it lines up with the flash erase block. I thought I could do this with pvcreate --dataalign 1024, but this caused the data to be aligned to a 1024 sector boundary within the partition, which itself starts on sector 63. I then thought the --dataalignoffsest switch would help, but specifying 63 there caused the data to be moved to sector 1087. I tried giving it -63, but was told that a negative number is not allowed. Why not? How can I get the data to start on sector 1024-63 of the partition so it ends up on pysical sector 1024 of the disk? _______________________________________________ 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/
