Drive capacity misreporting when creating pool

[Albullit]

I have a brand new clean install of 11.2 U4, using the hardware below.

• Dell R710, 2xL5640, 72GB.
• 8 Hitachi HUC106060CSS600 drives.
• Dell PERC H200 flashed to IT mode.

Initially when I went to create pool it bugged out with a non-zero exit code for dd. That turned out to be because the drives had a sector size of 520, so I ran

Code:

sg_format -v --format --fmtpinfo=0 --pfu=0 --size=512 --six /dev/da0

on all 8 drives to set the sector size to 512 (these are old NetApp drives I'm reusing for a homelab box).

Now however, when I go to create a pool via the web GUI, one drive, da0, misreports its size as 32MiB, rather than 558.91 GiB as the other sever drives do. Thus the GUI won't let me use that drive in the pool as there is a size mismatch. The drives though are all identical and all report the same in dmesg

Code:

root@freenas[~]# dmesg | grep ^da0   
da0 at mps0 bus 0 scbus1 target 0 lun 0
da0: <NETAPP X422_HCOBD600A10 NA02> Fixed Direct Access SPC-4 SCSI device
da0: Command Queueing enabled
da0: 572325MB (1172123568 512 byte sectors)

and with diskinfo

Code:

root@freenas[~]# diskinfo -v /dev/da0
/dev/da0
    512                      # sectorsize
    600127266816    # mediasize in bytes (559G)
    1172123568        # mediasize in sectors
    0                          # stripesize
    0                          # stripeoffset
    72961                  # Cylinders according to firmware.
    255                      # Heads according to firmware.
    63                        # Sectors according to firmware.
    NETAPP X422_HCOBD600A10    # Disk descr.
    PZHUEG5D                                   # Disk ident.
    No                       # TRIM/UNMAP support
    10020                  # Rotation rate in RPM
    Not_Zoned          # Zone Mode

I've tried wiping the disk from the GUI (quick never completes, zeros runs into hundreds of thousands of percent done), and also running gpart manually to verify the disk, which all look fine. But the GUI still misreports the size and won't let me use the drive. I've rebooted a few times, 'cos, Windows.

If I go to command line and create the pool manually, then import it into the GUI, its fine.

Code:

root@freenas[~]# gpart create -s gpt /dev/da0

So what about sg_format could have caused the GUI to become confused, and stay confused through reboots and wipes? Possibly this more a bug report than a request for help, I admit. But if anyone has come across this before I'd love to know if you solved it so the GUI works.
