  1. Storage Spaces not allowing full amount of drive space

    Good Afternoon,

    I have a fresh install of Win 10, version 10.0.19041. Attached to this system are 12x 12TB SATA drives. 4 of these are attached direct via internal SATA headers, and the other 8 are connected to an LSI 9300-8i card. I can see all 12 of the drives using disk management, and all 12 are available when I try to create a storage pool. Since each drive is showing roughly 10.9TB available, I should have a total of 130TB available. The problem is when I try to create the storage space, Windows lists 130TB available to use but when I choose Parity, the maximum size it allows me to create without yelling at me that there isn't enough room is 63TB.

    My math may be slightly off but with single parity, I should be able to create a roughly 119TB partition. Why is storage spaces limiting to half that? I even tried the other options: mirroring, no redundancy, and none of them are working correctly. Is this a bug?

    I downloaded drivepool, and it allowed me to create a pool with 10 disks at roughly 119TB with one unused, which would be my parity drive if it allowed that.

    I know there are lots of better ways to run large RAIDs, but I know Windows best, and this system will be used for many things to include file server. I looked into snapraid in conjunction with drivepool, and may have to go that route if I can't get storage spaces to work. And I was really hoping to have two parity drives, but for the life of me cannot get that to work either using powershell. Maybe another bug, but with 12 drives I would think Windows would yell at someone for NOT having two parity disks.

    Thanks in advance for any suggestions.

    Storage Spaces Disappears After Replacing Boot Drive

    Did you check Windows View update history list to see if KB4568831 has already been installed? I would think it has and that is why you got the message you did.

    If you have not run the Storage Spaces troubleshooter there are instructions in the other link on do it manually. What is accomplished in either case is that your storage spaces will be set to read only which will allow you to have access to the data on your storage space drive.

    The latter manual steps return the Storage Spaces drive to read/write and run optimization, defrag, and integrity routines. If your install is up to date then you should find the cumulative update KB4568831 installed in history. If you have upgraded to 20H2 then the patch discussed elsewhere to address the issue with Storage Spaces showing as RAW is rolled into the upgrade. In either case the manual optimization, defrag, and integrity routines can be run.

    extend c drive storage space

    Hi, I'm , an Independent Advisor.

    Disk Management is a Windows built-in tool that supports to increase partition size with its "Extend Volume" feature. However, the program has some limitations in increasing disk space:

    - Extend Volume only works on NTFS and RAW partition. FAT32 and other file systems are not supported.

    - The Extend Volume will grey out if there is no adjacent unallocated space behind the target partition.

    So, the ways to increasing C drive with or without adjacent unallocated space are different. Open the Disk Management, and follow the right tutorials listed below to extend the local disk C drive on your own now:

    #1. Increase C Drive Space with Adjacent Unallocated Space

    Step 1. Right-click This PC/My Computer, click "Manage", select "Disk Management" under Storage.

    Step 2. Locate and right-click on the local disk C drive, and choose "Extend Volume".

    Step 3. Set and add more space to your system C drive and click "Next" to continue.

    Step 4. Click "Finish" to complete the process.

    Note that if that unallocated space on your system disk is not behind the C drive, you can't extend C drive in Disk Management.

    Hope this helps. Let me know if I can help you further!

    Storage Spaces not allowing full amount of drive space

    Storages Spaces Configuration

    Progress Update

    I’ve had success but it has not been without a lot of pain and time.

    Major issues for me.

    • With my first attempts I was NOT able to create a Storage Space. As I research the issue I discovered one post that stated I could NOT have either a software or hardware RAID on the same system. At this time I did have the “LSI SAS9211-8I 8 Port” card installed.
      I’ve discovered that the card was set as a RAID card. At that time I was NOT able to get into the card BIOS and change any of the settings or software, thus I removed the card.
    • After removing the card I was able to create the Storage Space but this was not without discover of another issue. I wanted to use Parity which is like RAID 5 and I also wanted to use the ReFS file format. Initially because of my choices (Parity and ReFS)
      I could NOT create the Storage Space and discovered that MS does not support this combination but in the setup they allow you to select Parity and ReFS To resolve the issue I picked Parity and NTFS, this allowed me to create the Storage Space.
    • Another challenge was setting the value for maximum size for the storage space. As I understand it is best to establish a huge max size thus as you add more disk you do not hit the max size limit. If you hit the max size limit then it will be necessary
      to create a new storage space with a huge max size, move the contents of the first storage space to the new storage space. This would be super time consuming and require a lot of hard drives as temp holding space. After many attempts I settled on a max size
      of 50TB and with the three drives, 1-3TB, 1-4TB, 1-6TB, I had a space with 11.8TB and a max size of 50TB. This should be more than enough space for my data for the living years I have left remaining.

    Thus I finally had a workable storage space and my next step was to copy my “data” files to the new storage space so I kicked off all the necessary copy actions to copy the data. I used the high-level folder as my starting point. Following are two images
    showing the action. As you can see some have completed and some have a VERY long time remaining, e.g. 1913 minutes = 231 hours or about 10 days. I realize that all the copy actions are using the same drives thus this is a performance hit but it is a lot faster
    than me running one copy at a time thus forcing me to start another copy when one completed. But the actual performance hit is less than the time I would lose by the time gap between a copy finishing and me starting another copy. However there does seem to
    be a huge performance overhead with Storage Spaces. Originally I had to move the contents of the three drives in the Storage Space and if I recall this was completed in less than 4 days.

    After the copy to the storage space completes I see the following as the next steps.

    • Share the storage space with full privileges so all my other PCs can access the drives. This is quick task and should take less than 10 minutes.
    • Test to ensure all PCs can access the storage space. This is a bit more time and should take 1-2 hours.
    • Change ALL applications on ALL PCs to use the new storage space and confirm that all is working correctly. This could easily take a couple of days.
    • Use Hard Disk Sentinel (HDS) to reinitialize disk surface. This is an extensive test and will take about four days to test both drives being freed up, e.g. the 4TB and 6TB that currently have my data on them.
    • The HDS 4TB drive test will finish at least a day or two before the 6TB completes, when it does I could add it to the existing Storage pool or just wait until the 6TB HDS completes and add it to the storage pool. If I wait for the 6TB drive this would give
      me a bit over 17TB for my data. I feel that this will be more than enough to last me for whatever years I have left.

    At the same time I’m doing the above I can also work on the LSI SAS9211-8I 8 Port card and get it working, this will be for all of my backups. I have contacted LSI support via email and they did send information. Some of the info I was able to implement
    and others presented a problem for me. I sent a follow-up email last night but most likely will not get an answer until Monday. I was expecting a reply but so far no reply.

    After I get the card working I can create another parity storage space for all of my backups. Currently I have five drives connected to the card, 2-1TB drives, 1-1.5TB drive, 2-2TB drives.

    After I create the backup storage space, setup full permissions so all systems can access and confirm the access, the following steps will be performed. These will take several days or weeks.

    • Copy data from one backup drive. I currently have as backup drives, 2-2TB, 7-3TB, 3-6TB, to the temp drives attached to the card. I will start with a 3TB drive. By starting with a 3TB drive this will ensure I can replace one of the 1TB drives without space
      issues on the storage space. When I complete the backup storage space build it will have the 3-6TB drives and 2 or 3 3TB drives assigned to the space. This will provide between 23-26TB of storage for backups. If I need more space I can purchase a 10TB drive
      and replace one of the 3TB drives. Thus I’m playing a lot of musical chairs to get to the final build.
    • Confirm that all the backup data has been removed from the drive to the backup storage space
    • Change the necessary applications to use the backup storage space.
    • Confirm that apps are successfully using the backup storage space.
    • After the copy completes run the HDS test on the old drive. BTW the test level I’m using wipes out any data on the disk

    After the HDS test completes remove the smallest drive from the backup storage space and add the drive that just completed the HDS test
