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!,

Gordon

Here's the output from the lvconvert with verbose and debugging turned on:
