Yes it works well.

Use the standard RAID stuff to make a raid device, say /dev/md0, then create a PV (LVM Physical Volume) on that, then make a VG (LVM volume group) out of that PV, then create LVs (LVM Logical Volumes) in the VG.

Then (unless you have some other use for them), create filesystems in the LVs.

I use LVM over RAID1 on ATA disks using Ultra-ATA mode 4 (66 MB/s) or higher.

Not AFAIK.
