Mirror needs at least 3 PVs (2 for legs and 1 for dirty log) and you
don't have 3 PVs in that volume group!

I'm pulling my hair out trying to setup a mirrored logical volume.
lvconvert tells me I don't have enough free space, even though I have
hundreds of gigabytes free on both physical volumes.
Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data
Insufficient suitable allocatable extents for logical volume : 10240
more required
Any ideas?
Thanks!,

Here's the output from the lvconvert with verbose and debugging turned on:
# lvconvert -vvv -d -m1 /dev/vg1/iscsi_deeds_data

Hi !
IMHO, you would be good when using soft mirror (md) to mirror your 2 PV
and then make a vg on the md and then lv into it...
I use 3 disks to mirror my VG/LV and it is a waste. At next major system
upgrade I'll convert it to MD/VG and reclaim a disk.
Hope this helps !
