Title: Possible to spilt a RAID-1 without losing data on drives?
Post by: nails666 on March 31, 2013, 03:03:04 PM

Hi, I currently have my DNS320 setup with 2x1TB drives in RAID-1 but I'm planning to switch around my general network and backup setup and want to take one of the drives out and use it elsewhere. Is it possible to 'un raid' the drives so my data remains on at least 1 of the drives without having to copy it all off to somewhere else?

Many Thanks,

Ross

I doubt it is possible but I could be wrong.

In theory yes but the moment you put another drive in the unit it will try and rebuild the RAID array.

Since both drive carry identical data removing one does not destroy that data so you could remove one, reformat the remainder as a single disk then restore your data from the removed drive using techniques set out in various posts on this forum.  Just don't let windows try and read the drive without first installing a suitable IFS or software that can read and understand the Linux Ext2/3 file system.

Ok thanks for that.
