Storage Space - Inaccessible, reconnect drives

Hi
My 2 HDD Mirror Storage Space is no longer accessible. I cannot see it in explorer, and under Storage Space Manager it says Inaccessible, Reconnect drives. Both disks under Physical Disks are displaying as OK, so I'm really scratching my head.
The results from
Get-PhysicalDisk | fl *
Get-StoragePool | fl *
Get-VirtualDisk | fl *
Any help here would be appreciated, really scratching my head. Even when I connect each of the single disks on their own they don't show up
Are as follows:

  • Storage Spaces - unmark hard drive as "retired" after SATA controller failure

    Hello,
    I am having a problem with Storage Spaces - it won't start recovering the mirror set.
    The mirror set got degraded because one of SATA ports on the controller went bad (I/O errors with any hard drive on that port).
    After the hard drive is reconnected to another port, Storage Spaces still shows the drive as 'Retired'.
    I can unmark the disk by running Set-PhysicalDisk -UniqueID id -Usage AutoSelect
    Then, I can access a Simple (non-mirrored) thin-provisioned virtual disk located on that physical disk, and there are no I/O errors in Event Log, or any other errors.
    But after I attempt to initiate Mirror set repair (Repair-VirtualDisk -FriendlyName mirror), the physical disk becomes 'Retired' again, although no I/O errors have occured.
    Seems that somewhere in the metadata there is incorrect information about actual disk health state, and I need a way to reset it.
    Thank you.

    Thank you for reply.
    Figured out a workaround which solved the problem, however, it is somewhat crude (use at your own risk!):
    1. If there are any non-redundant (simple) virtual disks in the storage pool, back up the data somewhere (they have to be deleted and recreated from scratch)
    2. Disable the spaceport driver (sc config spaceport start= disabled), so you can see the hidden GPT partitions of type 'e75caf8f-f680-4cee-afa3-b001e56efc2d'.
    3. Reboot.
    4. Wipe the affected physical hard disk using diskpart (use
    clean command)
    5. Enable the spaceport driver (sc config spaceport start= boot) and reboot
    6. Now you can add the affected hard disk yet again
    7. At this point - the affected hard disk is listed twice - one in the 'Retired' state, the other is 'Healthy'.
    8. Initiate the repair of the affected mirror virtual disks, and wait for completion
    9. Now you can delete the 'Retired' disk.
    All that said, it would be great to have an option to un-retire a hard disk in place, without going through all that hassle.
    Set-PhysicalDisk -UniqueID id -Usage AutoSelect does not really work (the disk becomes Retired again when starting repair).
    Remove-PhysicalDisk also fails with 'Not supported' error (unless you do the above workaround).
    Thank you.

  • Problems with Storage Spaces

    I have a storage space with 10 drives, with over 10GB of free disk space in the pool.   Occasionally, certain of my spaces are inaccessible, presumably because two drives intermittently fail; these two drives total2.5g of physical space.  
    I have retired the two drives, but storage spaces will not let me remove them.  When I click remove it says : "cant remove the drive from the pool", "drive could not be removed because not
    all data could be reallocated. Add an additional drive to this pool and reattempt this operation".  
    How can I address this problem? 

    Hi,
    According to Storage Space FAQ, you could find the reason:
    Why do I have a low capacity warning even though I still have unused pool capacity?
    Storage Spaces provides advance notification of thinly provisioned storage spaces when the storage pool does not have enough capacity spread among a sufficient number of disks to continue to write new data. The default warning point is 70% capacity utilization.
    To learn when Storage Spaces will generate a warning, consider the following example.
    A two column, two-way mirror space that uses thin provisioning in a four disk pool
    Two of the disks have 1TB capacity and two have 2TB capacity. Because a two column, two-way mirror space needs four disks (number_of_disks = NumberOfColumns * NumberOfDataCopies), it will evenly consume all four disks as it writes new data. When capacity
    utilization of the two 1TB disks reaches 70%, Storage Spaces will warn of a low capacity condition. Even though the entire pool has 3.2TB free capacity, the thinly provisioned space will soon not be able to write any more data because the 1TB disks are nearly
    fully consumed.
    You can easily keep individual storage spaces’ low capacity warning synchronized with each other and with the pool by following the guidance in the next section, “How do I increase pool capacity?” from the moment of creating the pool and through all
    subsequent expansions of the pool.
    For more details, please refer to the link below:

  • Storage Space Size vs Pool Size

    Hi All:
    I just finished installing WS2012R2E and getting all my clients connected, transferring them from my aging WHS V1
    All seems to be working well but I'm scratching my head on the fact that the Storage Pool reports 3.63Tb of storage  (I have 2 x 2Tb drives) but the storage space reports 16Tb....  I tried changing the "Storage Space Size (Maximum)" to
    something closer to the actual storage pool capacity but no number seems acceptable to the field. 
    I get it (sort of) that the storage space is different from the pool, but it seems to me that if the dashboard storage tab reports the storage space with a Capacity of 16Tb it does not give a clear picture of my storage situation. 
    In addition to that quirk, the dashboard storage space window, hard drives tab reports 1Tb of used space but when I click into "Manage Storage Spaces"  that window reports that I'm using 2.16Tb of the 3.63Tb - ?!
    I've tried searching this with no joy - maybe I just haven't stumbled across the right doc yet...   Can some one enlighten or point me to a detailed description of they way this is supposed to work?
    Thanks!

    Hi,
    It seems that you directly click “Create a storage space” in dashboard. This wizard helps you create a default storage space on the server. The new storage space can tolerate on drive failure, and its size can group up to 16 TB.
    You can click “Manage Storage Spaces” in dashboard then click “create a new pool and storage space” to specific the maximum size of the storage space.

  • Windows 8.1 Storage Spaces... won't release the space

    So I have a Storage Space in Windows 8.1, it a 7 drive Pool in Parity mode with 3x 4TB drives and 4x 3TB drives. Things had been working well until I had a 3 TB drive fail, and had it RMA'd by Seagate. One of those 4TB drives was added just now also as
    an upgrade.
    The actual drive sizes add up to 24TB with a Formatted size of 21.77TB (3.63TB and 2.72TB respectively for 4TB and 3TB drives).
    When I added the 2 new drives into the array, I thought things would work well. Since Storage Spaces doesn't have anything built in yet to redistribute the data after adding a new drive, I did a copy and then a delete of the data. This is the best recommendation
    that I've currently been able to find to redistribute the data.
    However, I ran out of space. Weird, since I have ample free space.
    So I started moving the data off the array/space. I've now cleared the array down to just 2.62TB, with the Windows Properties reading 13.3 TB free (Parity Capacity is 15.9 TB, roughly 2/3 or the total space, which was expected). However, in the Storage Spaces
    listing, my drives are listed as 90% full. This is true EVEN NOW that I've move everything but 2.72TB left.
    Quick math: 2.72TB / 15.9 TB is 17.1% used, leaving 82.9% free.
    However, I can't seem to "release" the space. Again, copying the data over did NOT work. and Deleting the data from the array/space DID NOT work. I can't fathom how when I delete the data from the array, it still lists it as 90% full.
    Any help or ideas?

    Hi,
    Which method did you use to create Storage pool, simple spaces, mirror spaces, or parity spaces?
    Would you please capture a screenshot of your Storeage pool?

  • Odd storage space behavior for flash drive in USB port of E4200

    Using Mac OS 10.6.8 on a MacPro 2x2.8 ghz quad core intel xeon with 20GB ram
    I have a Linksys E4200 with Linksys Smart WiFi
    I have an unknown brand USB Flash drive in the E4200 router. The USB Storage status tab reads I have used 68MB of 1.87GB of storage space. The Mac Finder window reads the drive as having 2.8MB available. I have refreshed, disconnected and reconnected many times.
    I tried to copy a 49.5GB TIF file into the drive through the Finder and I get this error:
    Then I tried to copy a 2.8MB PDF file and got the same error.
    Keep in mind I was just able to copy this over yesterday--and delete it. Now I cannot copy it over. This same incident of the router changing it's mind happened with multiple folders and various files. First it doesn't take it. Then it takes it. Then it doesn't take it.
    Here's a weird error I got when trying to copy a game emulator:
    When I refresh in Linksys Smart Wifi, I am still told there is plenty of space.
    Now I deleted everything in the drive and successfully copied over a bunch of tiny 233KB files. Smart Wifi shows over 1GB of space remaining.
    Then I tried to copy a 160MB folder of small data files. Got the same not enough space error. So I tried a 7.5MB file. Same space error.
    Does anyone have any clue why this is happening? I tried to searach the forum and did not find anything similar.

    If that's the storage device then that's ok. From what you have posted this is just a 2GB usb flash stick. So if you cannot copy more files to it, it could either be the file format  you are transferring is not supported or the disc space is not enough. Connect the flash drive directly to your computer and test it that way. If you still cannot copy any files then I suggest that you reformat the usb flash stick.

  • I am receiving a notification that says that I am running out of storage space. I backed up time mating to an external hard drive. Can I delete some files to make room?

    I am receiving notifications that I am running out of storage space. I backed up my mac book using an external and time machine. Can I delete some files to make room?
    If so,
    When I want to restore from my time machine, can I pick and choose, say certain songs, photos or documents?

    About TM "Backup Drive is Full"
    Alert TM only deletes older files if they have been deleted from the source and when TM needs space on the backup drive for a new incremental backup. Time Machine "thins" it's backups; hourly backups over 24 hours old, except the first of the day; those "daily" backups over 30 days old, except the first of the week. The weeklies are kept as long as there's room.
    So, how long a backup file remains depends on how long it was on your Mac before being deleted, assuming you do at least one backup per day. If it was there for at least 24 hours, it will be kept for at least a month. If it was there for at least a week, it will be kept as long as there's room.
    Note, that on a Time Capsule the sparsebundle grows in size as needed, but doesn't shrink. Thus, from the user's view of the TC it appears that no space has been freed, although there may be space in the sparsebundle.
    Once TM has found it cannot free up enough space for a new backup it reports the disk is full. You can either erase the backup drive and start your backups anew or replace the drive with a larger drive. You can also use the Time Machine application to selectively remove files, but that may be ineffective if you have to free up GBs of space.

  • How to design Storage Spaces with a large number of drives

    I am wondering how one might go about designing a storage space for a large number of drives. Specifically I've got 45 x 4TB drives. As i am not extremely familiar with storage spaces, i'm a bit confused as to how I should go about designing this. Here is
    how i would do it in hardware raid and i'd like to know how to best match this setup in Storage Spaces. I've been burned twice now by poorly designed storage spaces and i don't want to get burned again. I want to make sure if a drive fails, i'm able to properly
    replace it without SS tossing it's cookies. 
    In the hardware raid world, i would divide these 45 x 4TB drives into three separate 15 disk Raid 6's. (Thus losing 6 drives to parity) Each raid 6 would show up as a separate volume/drive to the parent
    OS. If any disk failed in any of the three raids, i would simply pull it out and put a new disk back in and the raid would rebuild itself. 
    Here is my best guess for storage spaces. I would create 3 separate storage pools each containing 15 disks. I would then create a separate
    Dual Parity Virtual Disk for each pool. (Also losing 6 drives to parity) Each virtual disk would appear as a separate volume/disk
    to the parent OS. Did i miss anything? 
    Additionally, is there any benefit to breaking up my 45 disks into 3 separate pools? Would it be better to create one giant pool with all 45 disks and then create 3 (or however many) virtual disks on top of that one pool? 

    I am wondering how one might go about designing a storage space for a large number of drives. Specifically I've got 45 x 4TB drives. As i am not extremely familiar with storage spaces, i'm a bit confused as to how I should go about designing this. Here is
    how i would do it in hardware raid and i'd like to know how to best match this setup in Storage Spaces. I've been burned twice now by poorly designed storage spaces and i don't want to get burned again. I want to make sure if a drive fails, i'm able to properly
    replace it without SS tossing it's cookies. 
    In the hardware raid world, i would divide these 45 x 4TB drives into three separate 15 disk Raid 6's. (Thus losing 6 drives to parity) Each raid 6 would show up as a separate volume/drive to the parent
    OS. If any disk failed in any of the three raids, i would simply pull it out and put a new disk back in and the raid would rebuild itself.

    1) Try to avoid parity and esp. double parity RAIDs with a typical VM workload. It's dominated by small reads (OK) and small writes (not OK as whole parity stripe gets updated with any "ready-modify-write" sequence). As a result writes would be DOG slow.
    Another nasty parity RAID characteristic is very long rebuild times... It's pretty easy to get second (third with double parity) drive failure during re-build process and that would render the whole RAID set useless. Solution would be to use RAID10. Much safer,
    faster to work and rebuild compared to RAID5/6 but wastes half of raw capacity...
    2) Creating "islands" of storage is an extremely effective way of stealing IOPS away from your config. Typical modern RAID set would run out of IOPS long before running out of capacity so unless you're planning to have a file dump of an ice cold data or
    CCTV storage you'll absolutely need all IOPS from all spindles @ the same time. This again means One Big RAID10, OBR10.
    Hope this helped a bit :) Good luck!

  • I subscribed to 200 GB of Icloud drive storage space. How am I able to put my photos, documents etc. to my icloud storage?

    I thought the new icloud drive would function simlarly to dropbox or google drive. How do import a photo taken from my iphone or ipad to my icloud drive storage space?

    The "iCloud Photo Library" is still in beta right now and is not operational. it will probably be operational when the new Mac OS is released. When it is operational, both your iPad and iPhone will have the same "iCloud Photo Library".

  • MacBook Pro Retina with a 500gb hard drive - 400gb storage space?

    I have a MacBook Pro Retina with a 500gb hard drive. I recently deleted a windows 8 partition, and now my macbook says its total storage capacity is 399.42gb. Is this normal? Or am I missing 100gb storage space?
    When I deleted the partition through boot camp, there was an error, but the boot camp partition seemed to have been deleted completely. I ran disk utility repair and single user mode command prompt /sbin/fsck -fy to make sure my disk was properly partitioned, but it still shows 399.42gb total storage in my "About This Mac".

    You did not remove your Windows partition correctly. You need to remove it using Boot Camp Assistant. If you cannot then you will need to repartition the entire drive back to a single partition/volume.

  • How storage spaces mirror onto multiple storage pool drives...

    Tricky question to pose..
    I currently have 2 * 2TB drives in a storage pool.  I have a 2 TB storage space assigned to this pool (lets call them A and B).  I have 2TB of mirrored storage across 4TB of drives.  All is well...
    If I add a third 2TB drive "C" to the storage pool, how will 2-way mirroring work now?  My hope is that it will evenly mirror across each drive in the pool ( 1TB mirrored across A + B, 1TB across A+ C and 1TB across B + C) giving me effectively
    3TB of mirrored storage. 
    If it does work as I hope, does the server rebalance the mirroring?  Say I have already used 1.8GB of storage by the time I add in the 3rd drive, there is only 0.2GB on each of the morrored drives available.  When I add in the 3rd drive, if the
    server does not re-allocate, then I would only gain 0.4GB of storage (0.2GB A+C, 0.2GB B+C) leaving 1.4GB unusable.
    If not as I hoped, how do I make use of the 3rd drive?  I assume the 3rd drive is useless in that pool unless I do 3-way mirroring or I add another 4th drive?
    Thanks,  Mark.

    A Storage Spaces mirror configuration stores 2 copies of each data block on 2 different physical drives.  However, it does not balance the data.  So in your specific example, adding a third drive to a mirror environment won't help much. 
    You would really need to add a fourth 2 TB drive at the same time.

  • Does iCloud drive use up hard drive storage space?

    HI,
    I want to save hard drive space and use iCloud Drive to store my documents, pictures etc. I have the iCloud drive folder set up in my finder. I have been copying and pasting data in there, but it seems whenever I do; the hard drive storage space decreases.
    I thought the entire point of iCloud was to use cloud storage and not offline storage; unless you download it from the cloud to your hard drive. Why am I losing hard drive space?
    Any help you can offer or suggestions would be very much appreciated

    Hi FlyFalcon,
    I am writing to say that I am having the problem you are worried about. I have a 121 GB MacBook with flash storage, and I am running out of room.
    This is my work computer so I don't have any personal photos/music/movies stored on here. My iCloud drive has over 100 GB on it and it's driving this computer nuts! I am constantly getting the "your startup disk is full" message. As you can see from the screen shot below, it's saying I have 58.61 GB of photos on this computer, 25.84GB of movies etc...but all these files live on my personal MacBook at home.
    I am paying for the $3.99 a month for 200 GB but I didn't get that iCloud would use up my HD space. So as a warning, 128 GB may not be enough for you.

  • Storage spaces can only use whole drives

    One of the features that I was really interested in with WS2012E is storage spaces as it replaces the old driver extender of WHS v1. Having now installed WS2012E onto my WHS2011 box I am bit staggered to find that it can only use whole drives. My box came
    with 2 * 2Tb drives, the first partitioned as boot, then a 60G of OS followed by the rest allocated as storage. I have successfully created a Storage space pool of the second drive but cannot find any way to add the remaining storage from the large partition
    on the other drive into the pool. As the UI just shows me drives rather than partitions, I am bit challenged. I thought that storage spaces was meant to be flexible about adding drives just like the old drive extender. Even add on technolgies like DriveBender
    for WHS2011 allows for a storage space to be made up from this type of set up. So we seem to be going backwards.
    Plus when creating the drive pool it defaulted on a 2Tb drive to a 2Gb size! How useful is that? As soon as I started copying data to the drive it ran out of space. I then had to go in and expand it.

    I note that you did this with Windows Server 2012 Essentials.  I cannot seem to do this with Windows 2012 Standard.  I have two 500 GB disks and 40GB of the first disk, PhysicalDisk0 is partitioned for the OS.  Nothing I do makes PhysicalDisk0
    show up in the Storage Pool area of Server Manager - all I can see is PhysicalDisk1.  (Refer to 'Physical Disks' in the bottom right corner of the previous poster's first screen shot above.  I can only see 'PhysicalDisk1', not 'PhysicalDisk0'.)  If
    I click 'Disks' just under 'Volumes' in the same screenshot above, I can see PhysicalDisk0, and it shows 466 GB capacity, 423 GB unallocated.  PhysicalDisk1 shows 466 GB capacity, 466 GB unallocated.  My intent was to mirror the remaining 423 GB
    on PhysicalDisk0 with 423 GB on PhysicalDisk1.  I would then allocate the leftover 43 GB on PhysicalDisk1 as a 'scratch' disk.  I have tried leaving everything unallocated and have tried all variations of creating volumes and virtual disks, but nothing
    I do makes a difference.  I found other threads related to this issue which indicated there was a flaw in the 2012 GUI and that this process could be done via Powershell.  However, there seems to be a mix of Windows 8 and Windows 2012 in these threads
    and, apparently the Powershell commands I've found apply to 8 and not 2012, as I get invalid command errors when I try to use them.
    Can anybody tell me how to mirror the unallocated portion of the primary disk PhysicalDisk0 (which has a partition for the OS) with a same-sized portion of PhysicalDisk1 with Windows Server 2012?  Thanks!

  • Storage Spaces vs Plain-Old-Partitions on single-spindle 300GB drive

    When I originally installed my first WS2012 system (running WSUS, DHCP, WDS), I created simple volumes on the drive as I've always done. OS is installed on a 150GB drive, and I have a second 300GB drive that's providing storage for WSUS, WDS, and who knows
    what else I'll do with the 70% of that drive that WSUS/WDS will never use.
    I'm familiar with the concepts and intents for Storage Spaces, but is there any compelling reason to use Storage Spaces on a single-spindle drive? If not, then I'm happy to just leave it as it is and invest my time in other endeavors.

    If you'd create Spaces with redundancy (mirror or parity) and use ReFS on top you'll have much more stable config. Classic LVD + NTFS are not capable of handling anything related to silent data corruption (if SCSIOP_READ10 completed OK storage stack will
    think read is OK and NTFS has no mechanism to check for data integrity either). SS + ReFS will both detect and try to fix the error a) mapping new block and b) relocating data using alive content. That's in theory :)

  • Storage Spaces on WS2012R2 Server Essentials drive space error

    So, I finally bit the bullet and retired my V1 Home Server in favor of building out a Windows Server 2012R2 Server Essentials box as a replacement. All seemed to go well with the install and so I built out a Storage Space (16 TB) using an external 8-bay
    enclosure with about 14 TB of drives in it. The Space built out fine and I then moved my Server Folders to it which also went well.
    At that point, I attached my 4 TB external drive that had my movie backups on it and started copying them over. After about a day and a half it is done, or so I thought. It copied over about 3.2 TB of data and now when I try to copy basically anything onto
    the Storage Space, I get the following error message:
       There is not enough space on <folder name>
       xx.x GB is needed to copy this item. Delete or move files so you have enough space.
    <folder name> is whatever the target folder name is and xx.x is whatever size the file or files add up to.
    This then just has an option to Try Again, Skip or Cancel. Problem is, the drive only has a few TB of data on it and still shows mostly empty, yet I can't copy hardly anything to it. It seems to allow me to copy smaller files individually, but any larger
    group of files, or a folder with larger files in it yield the error above.
    Anybody have any ideas?

    Hi, 
    What is the resiliency type of the virtual disk in the Storage Spaces? How much the free space of the virtual disk? The issue may because the free space of the virtual disk is less than 4 TB.
    You could refer to the articles below to know more about the virtual disk size of different resiliency types:
