    8 drives with read errors at the same time?

    in General Support

    Posted

    Thanks for your reply @JorgeB

    I definitely wouldn't have expected a power issue, its a highend Corsair PSU, running off a UPS, but ok, stranger things have happened.

     

    New issue, stopping the array or trying to shutdown appears to do absolutely nothing. The log is 100% full at the moment, perhaps related to it not responding to these actions, but i also can't figure out how to clear that down without a reboot.

    Without any new log entries to view, i have no idea why its not stopping the array or shutting down.

     

    Any advice to get a clean shutdown?

     

    Thanks,

    Hi,

     

    Never had read errors before, dont know what to do. Any help would be greatly appreciated.

    Unraid is reporting that 8 drives have suddenly encounted read errors. I find that somewhat hard to believe.

     

    Some remarks:

    • Unassigned drives is suddenly showing all 8 of these drives with new sd[x] id's with some sort of failed array icon, while they appear to still be in the array.
    • My genuine Unassigned drives arent even showing up any more (maybe a limit to how many the dashboard can display)
    • Only 2 random 8TB drives didnt have any errors, every other array drive (inc. 2xParity) did.
    • 6TB drives all have 1036 Errors, and 8TB+ have 1133, suggesting that these failed reads were across all drives at certain ways through the data. But i think it was fine this morning, so happened today at somepoint. I havent done a partiy check in over a month, so why would all drives be read at the same time?
    • Some drives are connected via an HBA, some direct to motherboard controller. Parity is definitely on motherboard, 6TBs are definitely on HBA, so it doesnt appear to be a controller issue, because affected drives are spread between both.
    • im running 6.10.3
    • Between 2pm-3pm today, I did attempt to start a years old VM accidently, that failed miserably erroring on all sorts of issues. It wasnt something i expected to work, it would have been attempting to pass through GPUs that didnt exist, and used a drive image (or potentially a physical disk) for the OS that were no longer present. I feel this might have been around the time the read errors happened, but i dont understand why launching a VM would affect the array's data drives.

     

    Please help. I want to ensure my data is safe, my offsite backup hasn't been working for about 2 months, have been meaning to sort it out.

    Tempted to restart the server if it just resolves a one-off issue, and sorts out the unassigned drives plugin, but dont want to lose any diagnostics data.

     

    Any assistance appreciated, thanks,

    Hi,

     

    I'm trying to mount a WD Gold 6TB Drive, that's 4KN.

    It mounts absolutely fine, formats fine with NTFS,XFS or exFAT, and if i share it, i can see the full 6TB is available and working.

     

    However, if I pass it through to a windows VM, it shows as 3 partitions, two of which are unallocated. if i try and create a new partition within windows DSKMGR it just errors. Tried with diskpart too, errors on any action.

     

    Is there a special way to do this for 4KN drives, or is this issue nothing to do with 4kn?

     

    Im running 6.6.6 with UD: 2019.01.22a

    I've attached screenshots here, showing details of config. I have another Seagate 2TB drive that mounts and passes through to windows fine.

     

    Thanks,
