ZFS Duplicated data?? maybe
Posted: 22 Jan 2015 03:10
G'day,
I am a new member of the forum although I have read a lot of posts in the past out of interest.
Some background. I had a Freenas setup with 8 HDDs 6 of which were individual and two as a mirror. As always happens some of those drives got full and .. well you know the story.
I took the opportunity of starting from scratch with NAS4Free and ZFS. I copied all the data off to external storage. Installed NAS4Free on a "Boot" drive and then using the web-browser GUI set up the system as follows.
For ease of explanation I will call the drives A1 & A2, B1 & B2, C1 & C3, D1 & D2. (Note that A, B, C & D are different sizes. The 1 & 2 indicate equal sizes.) I made mirrors of A1 with A2, B1 with B2, C1 with C2 and D1 with D2. I then made a Pool with Mirror1, Mirror2, Mirror3 and Mirror3
I am a bit hazy on what I did next but I copied back all the data. I created two "folders" Rescued and Backup. The copied back data should be in Rescued and Backup is for new data.
Now the problem I have is that all the folders I copied back show up in both places "Rescued" and Backup" I would like to know how to correct this situation. I may have used the wrong terminology in some places here in my explanation.
Would it have been better to make a pool of A1, B1, C1 and D1 another of A2, B2, C2 and D2 and mirrored those pools?
Thanks for your time in reading. Hopefully someone will understand and lead me in the right direction.
