Hello!
I have a DNS 323 (rev. C1)
I have 2 disks (1tb, 2tb) and 2 raid devices (volumes):
- 1tb raid1
- 1tb linear (JBD)
I'd like to replace the 1tb disk with a 4tb. (I've installed Alt-F firmwere to do so)
The point is that the JBD partition has 1gb to the 1tb disk, so when I remove it the volume becomes degraded and it disappears, I don't know why but when I created it, it kept 1gb to the other disk, when I wanted to put it all in one disk.
The perfect solution would be obtain in the end a 2tb raid1 volume, and a 2tb single disk volume, but the first problem I have to solve is to "convert" the JDB volume to a single disk volume
Obviously, keeping the datas
Do you have any advice?
Thank you,
Paolo
ps.
these are the details of my configuration (the raid1 is currently degraded as the /dev/sda2 is removed)
