Storage RAID 5 and Dashboard reported capacity don't match (not even close)

1. offizieller Beitrag
    • Storage Software RAID (RAID 5) reports: 10.92 TB
    • Storage Disks reports 5.46 TB for each N300 6TB drives

    this is correct you don't get a full 6TB out of a 6TB


    my 18TB x 6 gives 16.37TB each drive


    so 90TB is 81TB


    as for the random sizes i have no clue lol

    Blue Coffee, I don't want to seem ungrateful for your response. But did you read all of the data? I provided all the information for consideration including the "Dashboard "File System" - table version reports: 6.74 TB capacity". I also said that none of the reported capacities throughout the OMV report the same capacity. Capacity is capacity. Before I retired, I was a Director of Computer support services for Unisys. The storage team reported to me: Oracle, Sybase, SQL. I understand there is overhead costs per disk in storage but not that much. Now if the reported capacity in OMV is 10.93 TB, I can buy that but not 6.75 as reported by the Dashboard "File System" - table version. Additionally, I would say based on my experience that raw NEW capacity from drives like 6TB should not be reporting a loss of ~520 GB for overhead or WHATEVER. Again, if all 3 capacities reported in OMV were the same, then perhaps I would not have a leg to stand on but non of them agree with each other and one show's almost half of what I should be seeing 10.92 TB versus 6.75 TB. Nobody can defend this. It has to be a bug.

    Dashboard "File System" - table version reports: 6.74 TB capacity

    The filesystems table doesn't report total capacity. It reports used and available.

    Zitat von acuity2009

    Dashboard "File System" - grid version reports: 10.83 TB capacity

    This is correct for a three 6TB raid 5 array.

    Drive capacity is misunderstood sooooo often. A 6TB is 5.46 TiB which is what OMV is reporting. You can't just drop the important 'i'

    There is no bug here.

    I did say this.

    Ive just checked on my OMV as i only have the grid abled I added the table as well.


    Grid says /dev/nvme0n1p1 826.15 GiB 89.65 GiB

    table says /dev/nvme0n1p1 915.82 GiB 10.0%


    from the look of it if i knock 10% of 915.82 it gives 826.15.

    so have you used about 4TB on data?

    ryecoaaron, indeed you are correct. I quickly assumed the that table and grid file system reported the same information just in different layouts. Why is the grid file system showing slightly different capacities 10.83 TiB vs 10.92 under RAID 5 management? What am I missing?

    ryecoaaron got me the answers I needed. I provided one follow-up question, then I'm good. Thanks again for the quick response.

    The array is 10.92 TiB which the Raid tab reports but the filesystem is 10.83 TiB (dashboard is reporting filesystem sizes) because the filesystem needs space for journals, inodes, etc.
