Re: client (-1) cannot open NBD device /dev/nda or similar: Nosuch file or directory

Hallo together!

I want to mirror a few server over the network to target mashines via =20
enbd/mdadm. If FR1 was developed for notebook users to do spontaneous =20
intellient RAID1 mirroring with an externel device, it should also be =20
suitable for my scenario.

Question: Is it possible to mirror the local disks without reorganizing =20
them? I want to keep the structure of partitions and volumes. The best =20
thing would be a copy on write mechanism to the target machine by the enb=
d =20
/ /dev/nda -device. A kind of daemon observing changes on /dev/sda and =20
mirroring it to /dev/nda(x) would be fine.
Does anyone know a solution? Googling didn't help very much.

This helped! I should have read the section about testing more closelay. =
A =20
reference to MAKEDEV in the Chapter Howto-2 would be helpful.
