That is correct.
And you can have files outside the Pool on a Pooled drive as well, like the lightroom folder. No clue why anyone would want that but...you can.
-
I believe I have the IBM M1015 but called Dell H310. I think it is the same card and I use it in IT/JBOD mode. No issues whatsoever, it drives 6HDDs and I got two more ports available.
The only thing I can not get it to do is allow for the drives to spin down.
-
Are you able to add additional drives to the machine first before beginning file operations? It is going to be a somewhat lengthy process anyway unless you have a full backup, then it is still going to take time but it'll be a bit faster and easier. Do you use Server Backup, I am asking because of the 2TB Server Backup volume limit that you can get around a bit cumbersome but it does work.
Yes, I would upgrade to the latest version but that is unrelated (except for dealing with the 2TB limit) to the issue at hand IMHO.
-
I agree Raid (or DP) is not a backup.
What read speeds does your media library need? I've never heard of spinners not being able to feed a stream.
Yeah, I'd say Raid-10 (or 5) offers better read speeds but at the cost of inflexible disk configurations and less flexible recovery mechanics.
-
It's been asked and I got the impression they won't. Apparently, keeping parity has quite a performance impact? The nice thing about DP is that you can mix and match I guess, no requirements on any size differences between disks and recovery is fast a disk failes (at x2 duplication).
-
AFAIK, DP can use Raid-arrays as disks in a Pool. DP does not, however, provide RAID-functionality itself (other than duplication which is sort of a file-based Raid-1).
-
That does not seem unreasonable to me. Having said that and having done some programming myself I can also easily see how that would not be implemented.
-
Well, not incredibly....
But it would have been more efficient if, for instance, you set Drive limit options in the Drive Usage Limiter. Removing drives is a serial / single "thread" I think. I don't know how one could have known this easily.
-
I am not sure about this but I would.
-
BTW, I am not even sure DP supports a NAS as part of a Pool. USB enclosures will work (but I still think USB enclosures are not advised by Stablebit).
-
Pools behave as if they are regular NTFS formatted volumes. However, any software that uses VSS (which many backup solutions do) is not supported. I don't know Crashplan so couldn't say. Having said that, you could backup the underlying drives. If you use duplication, then Hierachical Pools can ensure that you only backup one instance of the duplicates.
-
OK, sounds seriously borked to me. I would try to run Windows Update, then reboot, then try installing DP again.
But also I would submit a ticket here: https://stablebit.com/Contact
You do get support through the forums but it can take a while sometimes. This should be faster I think.
Good luck.
-
Have you tried rebooting and then installing DP?
-
OK, the Select Items indeed looks fine.
I have no experience whatsoever with backing up to a shared network folder. What does that point to specifically?
Would you consider trying to backup to a dedicated HDD (first and recommended option)?
As an aside, I would never backup to a destination that can only hold one backup....
-
I was hoping for the screen you get when you press Next twice. Now I am also interested in the Specify Destination Type screen. Not sure if I can help but those are the ones I would look at.
-
Do you configure Server Backups through wbadmin.exe? (I run WSE2016 so I am a bit unsure how it works with WS2019). Could you post a screenshot of the 'Select Items for Backup" screen?
-
I think you mean errors in the Event Viewer? Anyway, I can confirm that running WSE2016, Server Backup runs just fine with me. I also include some of the underlying Pool drives (not the Pool itself, that won;t work and should give errors such as above).
I don't know, Christopher might know. What I would look at, again, is the Server Backup setup and really ensure it is not trying to backup the Pool. Can you find out what Disk 8 and HarddiskVolume22 is?
-
No worries.
You do want to edit the list (don't do a new post, edit the existing one). Prior to step 2, one should stop the DrivePool service. After step 2, restart the service (or reboot). This is not trivial because while you are moving files into a Pool, DP may start to rebalance.

So AFAIK, everything DP reports wrt space is in terms of actual disk space. Assume a Pool of 2 x 10TB drives, x2 duplication except for one folder named UDF (UnDuplicated Files).
- Pool is empty and shows 20TB free
- Save a 1TB file to the Pool. The Pool will show 2TB Duplicated and 18TB free.
- Save 2 100GB files to UDF (two files because one would complicate a bit and cause Unusable for duplication, now one is on one drive, the other on the other). Pool will show 2TB duplication, 0.2TB unduplicated and 17.8TB free.A duplicated file is indeed seen as a single file _assuming_ you access the file through the Pool / DP. However, a x2 duplicated file is stored on two HDDs. Each has a hidden PoolPart.* folder within which the file resides. If you access the HDDs directly, you can see two files. In the above example, if you pulled one HDD (so it is still working) and put it into another PC, then yes, on that PC you can simply navigate to the PoolPart.* folder and find all your, duplicated, files (unduplicated is a matter of chance of course). DP stores everything in plain NTFS so that is nice from a recovery point of view.
Now assume one of the 10TB drives crashes, hard. DP will put the Pool in read-only mode. You will add a new 10TB HDD to the Pool and remove (through the GUI) the faulty one. At that time, DP will check for duplication and find none are duplicated even though most should be. DP will then re-duplicate. Non-duplicated files stored on the faulty HDD are lost (barring recovery and/or actual backups).
I guess that's basically it.
-
What you can do is tell Scanner to ignore this error (and just this one, not possible new ones). What I would do is have it scan the drive again. If it comes back with a bad sector, see if you can RMA it.
-
Use remove. You can move through Explorer but if you do that you need to stop the drivepool service first. Moreover, once you start DP service, it may try to rebalance files back to other drives so you need to turn of balancing to prevent that from happening. Also, if you have duplication then you want to disable that first. Yes, it will all take some time but it has, AFAIK, never failed. Quick and dirty though... not that failsafe sometimes. And even cutting/pasting will take quite some time.
-
I can't imagine DP having issues with drive-managed SMR HDDs.

12 hours ago, easyrider said:
I would still like to access the data on the single drives...
In that case, remove the drive letters but map the drives to folders within the Pool. I don;t know exactly how that works but it can be done and has been discussed here in the fora.
Looking at options - Windows Server 2019 (Parity/RAID-5)

That's fine. What I just don;t understand is that even 4K should have a bitrate of less than 40Mbit/s so I don't see how this helps. I wonder whether a single HDD wouldn't be able to provide that (unless in transcoding there are writes to the HDD as well but there Raid-5 would be penalizing methinks.
