it is automatic
though you should avoid power losses as better as you can
with online PSU against line interactive ones ( which are good for consumer PCs
and displays)

Oggetto: [linux-lvm] Power loss consistency for RAID
Dear all,
I'm recently considering using software RAID instead of hardware
controllers for my home server.
AFAIK, write operation on a RAID array is not atomic across disks. I'm
concerned that what happens to RAID1/5/6/10 LVs after power loss.
Is manual recovery required, or is it automatically checked and repaired
on LV activation?
Also I'm curious about how such recovery works internally.
Many thanks,
Zheng Lv
