Change current ssd to raid1
Change current ssd to raid1
Hi there, I just ordered a second (similar) ssd to the one I have. Not a boot drive. Once it arrives, I'd like to put it in raid 1 with my current drive. The current drive is not empty (but I could back it up if necessary).
I have used mdadm in the past but never with a drive that is actually in production use. Which steps would you suggest?
Have a good one!

What I usually do:
- create degraded raid1 with the new disk only
- copy the files over
- adjust fstab if needed
- wipe the old disk and add it to the raid
- wait for the kernel to resync it
Also suggested by SLES: https://documentation.suse.com/sles/15-SP1/html/SLES-all/cha-raid-degraded.html
Sounds absolutely legit to me. Aside this, a backup will never hurt.
