OK, I am mixing up threads, sorry bout that. I guess D is the new HDD. Everything I said above is true expect that D may not be faulty. The question is, why does it have arrows at the right (showing that DP does not want to write to it)? Other than the x3, are all balancers at default with default settings? If not, what is specific with you?
-
No. What does the status bar just below what you pasted look like? Is the faulty HDD stil in the Pool (the D drive perhaps)? If your Pool is K, J, D and I and D is the faulty HDD then I do see what the issue is. You have 6TB of data spread over 3 disks (the faulty HDD does not count because it is, well, faulty!), that is 2TB per disk. As your smallest HDD is 2TB, you have 3 HDDs and x3 duplication, there is no way you can have more than 6TB of data in such a pool. You need another HDD or replace the 2TB with a larger one.
Mind you, if you have x3 duplication on 3 HDDs, then the max you can store is 3 x [smallest HDD size]. If you have more HDD than the duplication factor then this is typically not a problem (it can be, say 1x14TB + 3x3TB still won't let you write more than 12TB or 4TB net of duplication but you get the idea).
-
AFAIK, no. DP does not warn. Which is good as many have it running on servers. I do not know of a way to get the behaviour you desire.
-
Yes, I noticed the (small) size differences as well which I do not understand but perhaps they differ in brand or in logical sector size.
Anyway, the bad sector HDD, is that I:? If so, then DP is trying to migrate all the data off of it. You could click on the DP symbol in the top left where it says "2" for more info. Also I wonder whta DP says at the pool organisation bar just below where the screenpic ends.
I am not sure but I am thinking you should replace that HDD and, given how little space you have left, perhaps add another disk as well.
Edit: Or replace with a far larger HDD. Personally I prefer more and "smaller" HDDs (in your case, 6 or 8TB instead of, say, 12/14TB) as they are quicker to rebuild/replace but the cost is more energy use). With this much data I would also wonder about backups.
-
Do you have scanner as well?
-
Are your balancers all at default settings? I wondr why you have that red arrow for disk 2 / I:. What happens if you force a rebalance?
-
What may be good to know is that when you write a file to a Pool, DP will select a disk, based on the balancer settings, and that selection may point to a HDD with little space free. Then a write will fail. DP does not spread individual files over more than one disk.
-
Yeah, so my remarks about duplication were useless actually. You already said you did not use any and I was confused by the "x2" information (weird that).
It was because due to the ordered file placement causing DP to try to write to disk 8 which only had, I think, about 8GB free. How 1-2GB deletions helped I don't know. Anyway, I don;t think there is a real need to use order file placement and it can in fact cause some of these kind of issues I would think. But adding a drive would help a lot.
-
I see an "x2" to the left of the pie chart, that indicates at least something is duplicated?
Oh wait, it probably tries to write to Disk 8 to fill that up first and that one does not have enough space. Do you have it set to fill up drives to 100%? How much are you trying to write?
-
You can, just not as x2 duplication because the 480GB free space is (mostly) free on one single HDD. DP will not write duplicates to the same physical HDD.
-
Yeah, so as you have used ordered file placement to fill up drives in order and, it appears, up to 100%, there is only 1 (one) HDD with free space. You can't duplicate to one HDD though so that is unusable for duplication. If you have 480GB free space in the Pool then one HDD should not have more than 240GB free or you can not use all space in an x2 duplication scenarion.
Personally, I would always want to have enough space so that the Pool can reorganise after a failure of the largest HDD. Perhaps it is time to add/replace a HDD.
-
And we see the "x2" thingy now, it seems to me it is working out indeed. Perhaps transferring over USB is relatively slow.
-
Any news? What does it look like now?
-
Yes, but that could not be seen from earlier screenprints and with Pool file duplication we get a nice "x2" thing to the left of the pie chart. Anyway, I would let it finish the duplication pass and then diagnose further.
-
Could you bring up a screenprint again with the Folder Duplication showing? What I fear is that you simply have no duplication. If you had then I would expect an "x2" to the left of the circle diagram. My advice is to set: Manage Pool -> File Protection -> Pool file duplication -> and then something I can;t see as I already have this but probably something like Enable Duplication and input that you want 2 copies of each file (remember those are not additional copies).
-
OK, that picture makes sense. I don;t knot about this but there is something with Plex that DP does not support ("hardlinks"?), but I don't know if that could cause this. If it has had very little progress for 8 hours then, personally, I would simply reboot orderly and see how that goes. Any reason to choose folder duplication over pool file duplication? What kind of box are the disks in and how are they connected?
-
I don't understand this at all, I wonder what this will look like after checking. You really need Drashna for this I think. As I read the picture, you have *no* duplication on anything other than in METADATA and apparently that takes up 78TB. That can't be right.
-
No. "x2" makes two duplicates, as in two copies of each file. Not two "additional" copies of an original. Not three in total.. It would help perhaps if you attached a screenprint of the GUI.
-
So if you look at the GUI, to the left of the graph depicting the Pool, do you see in green "x2" or something different, like "x2+"?
If it is "x2", then on on the right of the bar depicting the Pool Organization, isn't there a thingy where you can select to remeasure and/or rebalance? That would, I think, get duplication in order again.
(BTW, not to nitpick, but 1x duplication is no duplication. It is confusing but most use x2 for a set of two duplicates..)
-
I have no clue but
sorta indicates to me that you need to pass the drives and create the Pool in the VM.

That would work, but unfortunately, just wouldn't work for me. Lots of smaller drives of various sizes. So the hunt for a compatible backup program continues.
Size of individual drives don't matter that much, as long as lower - level pools are about the same size.
Spider99's suggestion may work well as well in combinatie with a solution that provides BMR for the OS.
-
I do not use OFP or FPR but I wonder whether you could set Automatic Balancing to every day at, say, 23:00, and uncheck the "File placement rules respect...plug-ins.".
Otherwise, if you do not duplicate between cloud and local, you could perhaps consider using the two seperate Pools and run a batch every night to move from local to cloud?
I don't think DP was made with a view to exhibit behaviour based on the time of day...
-
No, duplication is instantaneous. Which is good.

1. Install DrivePool (DP)
2. In the DP GUI, add the three 10TB HDDs to a new Pool (I would use the letter P for that one)
It is important to realise that existing data on the HDDs will NOT be affected but they will also NOT be part of the Pool. If you want to move those files to the Pool, you could do this: http://wiki.covecube.com/StableBit_DrivePool_Q4142489
3. Now set duplication to x2
4. Let DP do its magic.Be aware though that DP does not use parity. It is a file based solution that simply ensures that you have a number of duplicates where each duplicate is stored on a different physical device. As a result, 3x10TB will allow for 15TB net storage "only" with x2 duplication.

TL;DR but yes, DP will recognise the Pool. You could disconnect them all and plug them in on another machine and DP would see the Pool again.
One small caveat is that if you use plug-ins that are not installed on the new machine then you may have some unwanted behaviour. Other than that, it should work.
