but if a RAID got lost, you can always ask to

which is the unique data recovery company that has flat rates for raid recovery starting from 150,00 euro per disk

or the other way round, 900 euro for immediate/emergency recovery

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
