I'm trying to mirror my root fs and get errors that make no sense. What
am I missing?
PV VG Fmt Attr PSize PFree
/dev/sda1 vg0 lvm2 a- 111.79G 61.79G
/dev/sdb1 vg0 lvm2 a- 111.79G 111.79G
lvconvert -m1 -i 5 vg0/root
Insufficient suitable allocatable extents for logical volume : 7680
more required
Unable to allocate extents for mirror(s).
Then I tried explicitly telling it to allocate from sdb1:
lvconvert -m1 -i 5 vg0/root /dev/sdb1
Not enough PVs with free space available for parallel allocation.
Consider --alloc anywhere if desperate.
Unable to allocate extents for mirror(s).
There are two PVs so why does it complain?

What's up with "-i 5"? Doesn't that map to striping? you can't stripe
across 5 pv's if you only have 2.

No, -i is for update interval to show progress.
