New ReadyNas system, existing drives with data
Good afternoon, I was looking forward to purchasing one of the readynas devices, but I had 1 question. I have 2 500GB SATA drives in a linux box (ext 3, mirror via rsync) that I'd like to use in t...
Hello,
Please allow some very slight threat hijacking here, as my issue is practically the same but not being native English speaker, I'd gratefully get some more details on the above procedure.
My data is in a Taurus Gigalan; the disks are currently healthy, but I am not happy with the machine, then that's OT.
On my desktop I have been moving RAID1 arrays all the time, be it from machine to machine or from one Linux distro to another, but it seems not so simple with NAS?
If I understand well, you recommend this procedure:
0. Data is safely in your hardware, identical on 2 drives that we'll call sda1 and sda2.
1. Remove one of your 2 disks in your current hardware, call it sda2,
2. Set sda2 up in the new NAS, as a single unit, not redundant machine.
3. Start copy procedures between sda1 on former hardware and new NAS where sda2 sits; go do something else.
4 move the remaining sda1 disk from former hardware to NAS, set it up as mirror/new member of raid array, and go do something else again while the NAS syncs from sda2
Would that work?
can I just use rsync like in 'rsync -rluv root@OLDNAS:/my/folderrs/* root@NEWNAS:/my/folders' with the Duo?
Can I build the the RAID array after doing the copy with only one disk in the NAS?
Would the NAS accept sda1 as a "new" disk to include in a RAID1 array?
Cheers

Below, my current partition table in my cheap thingy:

It's all still ext2 AFAIK.
