Storage Spaces Slab Enumeration Fails
I'm trying to optimize my volumes, and slab enumeration fails consistently at 72%. The space is healthy, and I've tried everything I can think of. If I just ReTrim, no error comes up. I should mention that I'm on Windows 8.1, not Server 2012, but I understand
that the Storage Space part is basically the same, and I thought I'd find more help with that on this forum. If I erred, please let me know.
Thanks!

Replacing a failed disk in storage space ! unable to remove a retired disk
Hi Folks
Not really asking for much !! we are using windows 2012 R2 storage space ; one disk failed
and marked as retired.
today we received replacement disk ; added that to storage pool - fine.
then I repaired all Virtual Disk - process was very quick and went to 100% like a flash.
then I tried to remove faulty disk by using following commands :
$DeadDisk=Get-PhysicalDisk -FriendlyName PhysicalDisk-1
FriendlyName CanPool OperationalStatus HealthStatus Usage
Size
PhysicalDisk-1 False Lost Communication Warning Retired 185.5
GB
Remove-PhysicalDisk -PhysicalDisks $deaddisk -StoragePoolFriendlyName storagePool
this errored out ; basically saying that the above disk is still in-use !
Any suggestions ? does repair job take some time ? it looked very fast ; when I did get-storagejob ; it showed 100 percent completed .Hi,
Please reboot the server then set the failed disk to "Retired" and remove the retired physical disk.
You could refer to the thread below to troubleshoot the issue:
Degraded Storage Spaces Storage Pool after single HDD failure

According to William Stanek, in his Windows Server 2012 R2 Inside Out: Configuration, Storage & Essentials book, this is apparently possible: (pg. 615 - here it is on Google Books: https://books.google.ca/books?id=0IyfBAAAQBAJ&pg=PT819&lpg=PT819&dq=read+operation )
Integrity can be enabled when the system is not running on Storage Spaces. When
integrity is enabled and ReFS detects a checksum mismatch, ReFS logs an event and
fails the read operation by default. If you don’t want the read operation to fail, you
can configure ReFS to continue with the read operation. A related event will be logged
regardless.
So then how do I configure it to do that???
(And just to make it super-clear, I'm NOT using Storage Spaces, so there is no redundancy via mirroring/parity, and I'm not expecting any file repair - just detection of corruption. It's just a basic volume formatted with ReFS and
with integrity streams enabled, via format E: /fs:ReFS /i:enabled
For those who want more details, here's the situation:
I try to perform a read operation on a file with corrupted data (purposely done for testing using a low-level disk editor), I get a the following error message:
And an event ID 133 from ReFSv1 gets logged in the System log:
Clicking "Try Again" just brings up the same message, and clicking "Skip" skips the operation entirely.
This is indeed the correct default behaviour.
What I want instead is for the read operation to be allowed to complete, with corrupt data and all, and ONLY for the event to be logged. And according to William Stanek, this is supposed to be configurable somewhere - and after hours of searching, I haven't
been able to find anything.Hi Tommy,
>>How can I configure ReFS to NOT fail read operations when a checksum error is detected
We can use PowerShell command Set-FileIntegrity to configure this. The specific parameter for controlling this behavior is
-Enforce <Boolean>which indicates whether to enable blocking access to a file if integrity streams do not match the data.
Regarding this point, the following article can be referred to as reference.

Sync manager part fail: "Error: Insufficient Storage Space&qu
I'm using sync manager to transfer my collection of 3502 songs from my Zen Xtra to my PC before I upgrade to a 60GB Vision M.
It completes the sync but with 92 songs moved and a message that it is "complete with errors". The remaining songs each have the message "Error: Insufficient Storage Space"
The peculiar thing, my computer has 240GBs free!
Please can someone advise how to fix this and backup my songs? - Thank you.You're not the only one with problems synching with?an Xtra. It appears that creative introduced a bug in their newer software that causes the transfer to fail regardless of how much space you have. Try installing the old software that came with the Xtra to copy it off. Creative sure has stellar support for their products, eh?Next time I'll go with another vendor. This is simply shoddy service on their part.

Storage Spaces disk removal of damaged HDD failing
Hi, and thanks in advance for any help!
The general situation: I have a Windows 8.1 Pro machine acting as a home server. The storage spaces volume (singular) consists of a 4-disk array with 2TB drives in Parity mode. It's usage is 70ish% but honestly, maybe 50GB is important to
recover, the rest are ISO's which I have the physical disks to so no big deal if I lose those. The volume is in a bad place and I need to either get it functional again or get the data off of it and start with a fresh volume.
What seems to be wrong: One of the drives has failed. When the drive is attached the volume (D:) appears to mount but explorer hangs/crashes when attempting to access D:\. Storage spaces hangs/crashes as soon as you click "Change Settings".
Task Manager registers 100% I/O usage of the volume at those times. Taking the drive to another machine and running CrystalDiskInfo indicates a few fatal failures. Removal of the drive returns the system to a functional state but D:\ goes away.
Attempts to fix the issue so far: With the drive attached the storage pool will say 'repairing' and sit at 0% for at least 3 hours (at which point I gave up). All further attempts I've made have been w
ith the bad drive physically removed. Removal of the drive via the GUI shows this error
Can't Remove Drive from the pool
Details: Drive could not be removed because not all data could be reallocated. Add an additional drive to this pool and reattempt this operation
At first I thought, simple: buy another 2TB drive and rinse-repeat. Did that, same error. This morning I went a step further thinking that maybe the 2TB drive was too small, fine- bought a 4TB drive, added that, same error output. Ok, since I have that 2TB
drive sitting on my desk, throw that in too, maybe having both the replacement 2TB drive and additional 4TB drive in the pool is good? no dice, same error.
I work as a systems guy for Linux so command line doesn't scare me, I'm not familiar with PowerShell specifics but I did some reading and tried everything that made sense (after a lot of googling and get-help <command> -full). I can't seem to remove
the drive from the pool and without it the volume wont mount. A general summary of the situation is below:

Any ideas? Again, all I really need is about 50GB of data off this array so if even there is a way to temporarily mount the volume, pull the data, and start of I'm game. Thanks again for your help!Hi,
How did you remove that disk and return the disk?

Failed downloads eating up storage space?
Hoping somebody can help me here, recently purchased a couple of TV series via iTunes and have been downloading and watching on both my iPad and iPhone. The problem is, they seem to get almost fully downloaded and then a message pops us saying unable to download. This keeps happening with various wifi networks on both devices, and I've noticed that the available space on both devices has reduced drastically. My iPad no longer has enough space for an HD episode, and my iPhone is reduced to being able to hold about 2 episodes. I go to settings>usage to see what the apps are using and they total very little in comparison to what the devices can hold. It's not even due to the number of photos/other documents in the devices as there aren't really any, or at least no way near enough to create the storage issues I'm experiencing. Starting to get really annoyed now as every time I try to download an episode I'm loosing storage space. The downloads do eventually work, but only after numerous attempts. It's not even like it's a dodgy download, or at least I hope not I paid good money via iTunes for the series!
In case anyone else finds this post with a similar problem.. I found a solution. (posted by a user named txforever)
Manually change the date back several months (or years if need be) and then go in to your Recently Deleted Photos folder. Don't be fooled by it telling you there are 0 photos. If you actually open it up, suddenly you will find all the old photos that should've been deleted but never were.
I emptied it and my problem is solved.
Hooray!
I feel like Apple should issue this as a known solution to this bug that a lot of people seem to be having. And also, they should fix the bug of course. -
WIndows 8.1 Storage Space failing -- having trouble even getting information.
Hello,
I've looked at a bunch of articles to try to sort this out, but haven't found anything. I hope I'm just missing something obvious. :-/
Here's my setup: in addition to a system drive, I have three additional, identical disks (WD Red, 2TB) that I have placed in a storage pool. Out of these, I've carved three storage spaces: two set for mirroring, one for parity.
Something's gone awry... (or I wouldn't be here):
If I try to open up the "Storage Spaces" control panel, it just hangs. Task manager reports it as "not responding".
In PowerShell, running "get-virtualdisk" reported the OperationalStatus of the three virtual drives as InService for a while, but then started showing them as Degraded. Interestingly, these degraded disks seem to flip back to InService every so
often. The HealthStatus is always listed as Warning.
Running "get-physicaldisk", however, shows all three physical drives with an OperationalSatus of OK and HealthStatus of Healthy.
The system shows ~25% disk usage, making me thing that something is going on, but who knows...
I can browse into the two mirrored storage spaces, and things superficially look okay. I cannot open up the parity space.
I have an offsite backup through one of these cloud services, but it will be cheaper and faster to get this machine back on its feet rather than order up a copy of the backup.
So, wondering how to proceed here:
Are things clearly hosed?
If there is hope, what are the next steps in debugging/fixing this?
Thanks in advance!Hi,

I have 4x3TB for my Storage Spaces at home. I am using windows 8.1. I am using Two-Way mirrored.I currently have 5.7Gb of data in use. Found out last week that I had a bad drive. The storage space kept repairing itself, when suddenly it gave me an error,
and suggested I replace disk. So I went ahead and replaced the drive with a new one. Here is the problem, The old drive is showing as "Retired" with 0.01% usage. The other 3 drives show as ok with 97.1% usage. When I add the new disk nothing happens,
it shows as ok, with 0.00% usage. I try to run repair-disk, and after 20sec, it comes back and completes. I then run get-storagejob and it says completed. Is anyone aware of how I can force the repair? Would using server 2012 help rebuild the virtual drive?
Additionally I have tried the steps in the TechNet article(Storage Spaces Frequently Asked Questions ), but have not had luck in getting the virtual to work.The old drive is showing as "Retired" with 0.01% usage. The other 3 drives show as ok with 97.1% usage. When I add the new disk nothing happens, it shows as ok, with 0.00% usage.
Did you remove the bad drive from Storage Spaces?

Hi.
Im trying to make the space volume enumeration of an object 3D.
In order to accomplish my objective i have made the following code:
Vector3d direction = new Vector3d(1, 0, 0);
for (double dz = 0; dz < 100; ++dz)
for (double dy = 0; dy < 100; ++dy)
//Posicao relativa do olho
Point3d eyePos = new Point3d(0, dy, dz);
pick.setShapeRay(eyePos, direction); // shoot ray downwards
pres = pick.pickClosest();
if ((pres != null) && (pres.numIntersections() > 1) )
pickedPoints = new Point3d[pres.numIntersections()];
for (int i = 0; i < pres.numIntersections(); ++i)
pi = pres.getIntersection(i);
pickedPoints[i] = pi.getPointCoordinatesVW();
} I have a problem. Because sometimes the number of pickedPoints are more than the number of interceptions betwen the ray and the object.
example: i send a ray against a sphere object and the code returns to points in duplicate:
(points returned):
1. pickedPoints[0].x = 0.5 pickedPoints[0].y = 1 pickedPoints[0].z = 6
2. pickedPoints[0].x = 0.5 pickedPoints[0].x = 1 pickedPoints[0].x = 6
3. pickedPoints[0].x = 7 pickedPoints[0].y = 1 pickedPoints[0].z = 6
The point3d 1. and 2. are equals.
Is that any away to get only the two points3d ( 1. and 3.) ?
thanksHi,
As you said a parity virtual disk should still working with 1 disk failure. I cannot confirm the exact cause at this moment. You may have a look on Event logs to see if any further information provided.
Meanwhile do you have a replacement hard disk? Try to add it to the pool, retire the corrupted hard disk and perform a repair to see if that could bring the virtual disk back online.
Please remember to mark the replies as answers if they help and un-mark them if they provide no help. If you have feedback for TechNet Support, contact [email protected]
I have the replacement disk added. I've retired the dead one, added the new one to the pool and attempted to run the repair from PowerShell. It looks like it's going to do something but it pretty much completes instantly, so doesn't actually
do anything. If I try remove the failed disk from the GUI it tells me that a repair will be done but without me even clicking anything, these dialogues disappear.
Looking in the event log, if I check the Operational log under "StorageSpaces-Driver" I see a message saying
Drives hosting data for virtual disk {ed94ba35-ea2b-11e2-93fa-00155d006604} have failed or are missing. As a result, no copy of data is available. Return Code: This device does not exist.
It's not looking promising that this storage space will be recoverable... -
First cluster - Server 2012 r2 - storage spaces issues
Hi Everyone
We just purchased two new servers (Lenovo RD640's) and an external SAS JBOD enclosure (the Lenovo SA120), and we would like to set up a 2012 r2 failover cluster with clustered storage spaces as the shared storage. Currently they are
on their own domain with the virtual active directory server residing locally on one of the servers.
Preface: I've created and destroyed the cluster and storage spaces multiple times trying to solve this issue, so I don't know if I may have "leftovers" from those attempts now causing issues for me.
I can create the cluster, and it passes validation, and can create a clustered storage pool, but every time I try to create a virtual disk (either through the Failover cluster manager, the server manager, or powershell), it won't attach. If
I try to manually attach it I get the message: "Error attaching or detaching virtual disk: Failed to attach virtual disk to <node name>. Access denied"
Finally (and I don't know if this is related or not), when in storage spaces on the server manager, there is a gold banner at the top that says "Incomplete communication with cluster <cluster name>. The following cluster nodes or clustered roles
might be offline or have connectivity issues: <cluster name>"
I'm logged in with full domain administrator credentials, and have been running my head against this wall for a few days now. Any help would be appreciated!Thanks for your responses. Here is what I have to report:
When I destroy the cluster, and create the storage spaces on just one of the two servers (with the other server powered down), I'm able to create the storage pool - using all the HDDs and SSDs - and virtual disks (both tiered and non-tiered) without issue.
As soon as I create the cluster again, the virtual disks become "detached", and I'm back to the situation described initially.

Unable to repair degraded Virtual disks in Storage Spaces under Hyper-V 2012 R2 Core
Hi all,
I am finding myself in the following conundrum. I have a storage pool under Hyper-V Core, with 2 2TB Seagate drives.
One of the drives completely died (wouldn't spin up, tried it in a different box, still to no avail). I sent it in to Seagate for warranty replacement, got the new drive. Installed it and went through the notions of adding it to the pool and retiring the
one that was with "Lost Communication" status.
Tried to repair the virtual disks that are showing as "Unhealthy-Detached", quickly get 100% complete, but the repair didnt work.
The storage pool is in degraded state.
Looks like metadata is corrupted.
Followed this post to upgrade Storage Spaces to latest version:
https://social.technet.microsoft.com/Forums/windowsserver/en-US/eead59e9-5e49-4bb6-8cbb-1dafddd9576b/unable-to-repair-degraded-virtual-disks-in-storage-spaces-2012r2?forum=winserverfiles
Still, to no avail.
Couple of questions:
1) Is the data on the 3 virtual disks in state "Unhealthy: Detached" not recoverable?
2) How can I get the storage pool back to "healthy"?
Any help will be greatly appreciated.

Install Windows Server 2012 R2 VM on Storage Spaces with Storage Tiers
Hey guys
In my small/medium sized company we will soon update to Windows Server 2012 R2. I would like to implement virtual servers using Hyper-V. I didn't find a lot of information about Hyper-V in combination with storages spaces and autoamted storage tiers.
And this is very confusing to me as it seems to me that this would be the best practice as it is the most cost-efficient and most elegant solution.
My ideal scenario:
With Hyper-V I virtualize two Windows Server 2012 R2 instances. So two separate virtual machines.
I use the following disk setup:
1x cheap HDD 40GB for hyper-v server 2012 r2 core.
2x SSD 200GB (enterprise-grade)
2x HDD 4TB (7.2k, enterprise-grade)
Step 1:
I will install Hyper-V Server 2012 R2 Core on the 40GB HDD. Via command line, I will create a storage pool with automated tiered storage using the SSDs and the HDDs in mirrored mode the following way:
With Tiered Storage, I create a storage pool containing the SSDs and the HDDs. Then I create storage space A (1TB) and B (3.2TB) with the SSDs in a mirrored setup and the HDDs in a mirrored setup. The SSDs for the „hot files“ and the HDDs for the „cold files“.
Step2:
Ontop of the storage space A I want to install the first Windows Server 2012 R2 instance with Active directory. On storage space B I want to install the second Windows Server 2012 R2 instance for a business application to run on it.
Conclusion:
The SSDs are mirrored and therefore one SSD can fail.
The 4TB HDDs are mirrored and therefore one HDD can fail.
I have a fast and easy scalable environment.
But in the Internet I found many information that it’s not possible to install an operating system onto a storage tier.
Question 1:
Is this setup possible?
Question 2:
If this setup is possible, why is not everyone doing it?
Question 3:
Is it possible to do Step 1 over a GUI from a remote machine?
Question 4:
If the creation of Storage Tiers in the Hyper-V Server 2012 R2 is not possible. Would it work to use a Windows Server 2012 R2 as a parent system on the 40GB HDD? To do Step 1?
I would gladly get some feedback of people knowing Storage Tiers well.
Thanks a lot!I would absolutely prefer a GUI. But a Windows Server 2012 R2 Standard Licence allows you to run two VM machines.
It also grants you a physical installation ("POSE" in the licensing documents). You can buy one copy of WS2012R2 Standard, install it on the hardware, enable Hyper-V, and then operate two virtual machines with WS2012R2 Standard ("VOSE"
in the licensing documents). The only restriction is that the management operating system (POSE) can only run services and applications meant to manage the virtual machines and/or the management operating system. The Hyper-V Server license is the same way
so it's not really any different.
In short, given the benefits of the GUI at your stage of learning, you have no solid reason not to install the full system and take advantage of it. You can disable the GUI later once you get your footing. Or not. Whatever suits you. However, in response
to your Question 3, you can do this all remotely. Once you get WS2012R2 installed in a guest, you can use it to manage the management operating system if you want. There are many options.
But then I would also need to have redundancy on the 40GB HDD as if this HDD brakes, all others brake as well?
Yes, you're going to want some redundancy for the management operating system. But, you've listed 5 drives in your original layout. You don't really have a 5-bay system, do you? Is there an empty sixth bay? Could you not get two 40 GB drives instead of one
and use hardware RAID-1?

Server 2012 RC. I'm using Storage Spaces, with two virtual disks across 23 underlying physical disks.
* First virtual disk is fixed provisioning, parity across 23 physical disks: 10,024GB capacity
* Second virtual disk is fixed provisioning, parity across the remaining space on 6 of the same physical disks: 652GB capacity
These have been configured as dynamic disks, with an NTFS volume spanned across the two (larger virtual disk first). Total volume size 10,676GB. For more details of the hardware, and why the configuration is like this, see: http://social.technet.microsoft.com/Forums/en-US/winserver8gen/thread/c35ff156-01a8-456a-9190-04c7bcfc048e
I'm copying several TB from a network share to this volume. It is very slow at ~12MB/sec, but works. However, three times so far, several hours in to the file copy and with plenty of free space remaining, the 10,024GB virtual disk is suddenly taken offline.
This obviously then fails the spanned volume and stops the file copy.
The second time, I took screenshots, below. The disk (Disk27) is marked offline due to "This disk is offline because it is out of capacity". And the disk in the spanned volume is marked as missing (which is what you would expect when one of its member disks
is offline).
I can then mark the disk (Disk27) back online again, and this restores the spanned volume. I can then re-start the file copy from where it failed. There doesn't appear to be any data loss, but it does cause an outage that requires manual attention. As you
can see, there is plenty of space left on the spanned volume.
Each time this has happened, there are a few event 150 errors in the System event log: "Disk 27 has reached a logical block provisioning permanent resource exhaustion condition.". Source: Disk.

This error seems to be related to thin provisioning of disks. I found this:
http://msdn.microsoft.com/en-us/library/windows/desktop/hh848068(v=vs.85).aspx. But both these Virtual Disks are configured as Fixed, not Thin provisioning, so it shouldn't apply.
My thoughts: the virtual disk should not spuriously go offline during a file copy, even if it was out of space. And in any case, there is plenty of free space remaining. Also, I don't understand the reason for why it is marked as offline ("This disk is offline
because it is out of capacity"). Why would a disk go offline because it was out of thin capacity, rather than just returning an "out of disk space" error while keeping it online.Interesting Thread, I've been having the same issue. I had a failed hardware RAID that was impossible to recover in place, so after being forced to do a 1:1 backup, I find myself with 5 2TB hard drives to play with. Storage Spaces seemed like an interesting
way to go until I started facing the issues we share.
So my configuration is A VM Running Windows Server 2012 RC with 5 Virtualized Physical drives using a SCSI interface, 2TB in size that make up my storage pool. A Single Thinly provisioned Disk of 18 TB (using 1 disk for parity)
Interestly enough, write speed has not been an issue on this machine (30~70MB/s, up from 256k on the beta)
Of note to me is this error in my event log 13 minutes before the drive disappeared:
"The shadow copies of volume E: were deleted because the shadow copy storage could not grow in time.Consider reducing the IO load on the system or choose a shadow copy storage volume that is not being shadow copied."Source: volsnap, Event ID: 25, Level: Error
followed by:
"The system failed to flush data to the transaction log. Corruption may occur in VolumeId: E:, DeviceName: \Device\HarddiskVolume17.(The physical resources of this disk have been exhausted.)"Source: Ntfs (Microsoft-Windows-Ntfs), Event ID: 140, Level: Warning
I figure the amount of space available to me before I start encountering physical limits is in the vicinity of about 7TB. It dropped out for the second time at 184 GB.
FYI, the number of columns created for me is 5

I tried updating to iOS6 via itunes bc my storage space was pass limit and now my phone is telling me it's in recovery mode and I need to restore it. I didn't back it up. How do I take it out of recovery mode and keep the information on my phone?
You cannot. If it is in recovery mode, the data is already gone.
Did you fail to make sure everything was on your computer before updating? -
Storage Spaces: SSD tier size incorrect when using EnclosureAware option in a pool
Hi folks,
We're about to deploy Storage Spaces in our test environment, but we encountered an issue while configuring Enclosure Awareness on Storage Pools.
When we create a Storage Pool (over 3 JBOD's) and set the option EnclosureAwarenessDefault to $True, the SSD tier size automatically decreases / shrinks to 12GB (sometimes 18GB sometimes 0GB).
Without EnclosureAwarenessDefault, we get 1110 GB of SSD size available.
The same behavior is seen when enabling -EnclosureAwareness on Storage Space (virtual disk) level.
A summary of our configuration:
3 SOFS connected twice to each JBOD (LSI 9207-8e - SES 3 ) = HCL certified
3 JBOD arrays (Quanta M4600H) (Firmware Management SCSI Enclosure Service (SES-2) = HCL certified
Each JBOD array has 16 HDD and 4 SSD.
SOFS are fully patched, including KB 2913766
Below 2 screenshots:
EnclosureAwareDefault = $True
https://onedrive.live.com/redir?resid=BB5A32452CA3BD6C%21436
EnclosureAwareDefault = $False
https://onedrive.live.com/redir?resid=BB5A32452CA3BD6C%21437Hi Partner,
Thank you for your detailed information and sorry for the delayed response.
After consulting with some senior engineers, please check the following:
Server manager does not let you set the column count of the space, which means that it is automatically selecting 6 as the column count, as there are 12 SSDs. Unfortunately, the column count must be less than the number of disks of each type in each
enclosure (limited by 4 SSDs), otherwise space creation will fail, and estimation will produce a small, somewhat random number. If you create a space through powershell and specify –NumberOfColumns 4 then it should work.
Hopefully it helps.
Feel free to let me know if you have any question. Thank your for your time.
Best Regards,
Sophia Sun
