[OpenIndiana-discuss] ZFS version issue

[Reginald Beardsley]

 OK. Another legacy format ZFS USB drive shows up with "zfs import" on the Z840. Also formatted on the u8 system.

WD drive works on 2017 on an old Z400, but is not seen on newer Z840 running 2024.10

FAT and other ZFS volumes in the same legacy format can be seen on the Z840.

To summarize:

The Z840 can see and import a legacy u8 ZFS pool on another USB drive. I am currently running a scrub on the disk using the Z840.

The WD drive can be imported into 2017 and u8, but not 2024.10. I am currently running a scrub on the WD on 2017 along with the 2017 disks which have not been scrubbed since 2023 as the system is mostly powered down for lack of maintenance.

This doesn't make sense. Where is the contradiction? It's not possible. Why can't 2024.10 see the WD drive?

FWIW I've run ZFS ever since I bought my Ultra 20 in 2005 which eventually migrated to the current Z400 based u8 instance: a 3 drive, 3 slice mirror rpool and 3 slice RAIDZ1 plus a single disk 3 TB ZFS pool for scratch space. I've had 3-4 disk failures and never lost data.

So to say I'm a ZFS fan would be a bit of an understatement. I wouldn't do anything much above the level of email via a web site without it.

None of those show the USB HD. A flash drive did show up using mdb and it automounted. So the USB port is OK, but it doesn't see the WD Elements HD.

Same disk, same cable. Two Z400s see the drive, 2017 and u8, but not the Z840 running 2024.10. Made sure the Z840 was seating the USB A properly.

I knew that things were just going too well when s10_u8 installed and ran on VBox on the first try with no issues at all.

There are a number of tools that might be helpful; e.g.,

    diskinfo
    cfgadm -alv usb
    mdb -ke ::prtusb



Cheers.
