gptzfsboot error

[Andrea Venturoli]

Hello.

I've converted an 11.4 machine from UFS to ZFS.
The machine boots via BIOS (not UEFI) and has two SATA disks partitioned
with GPT with a zmirror on them

At boot I briefly get the following messages:
gptzfsboot: error 1 lba 4721914626
gptzfsboot: error 1 lba 977724091
gptzfsboot: error 1 lba 977724603
(... lots of other messages like the above ...)
Shortening read at 5721751601 from 16 to -594023507
gptzfsboot: error 1 lba 5721751601

The everything goes on normally and FreeBSD boots.


I searched for an explanation, but didn't find any.
Is this something to worry about?
What's the cause of "error 1"?



bye & Thanks
av.

P.S. Initially I had setup the disks myself, but when I saw this error,
I removed them, let FreeBSD's installer prepare them from scratch and
moved them back in. So I don't think I got something wrong.

Hi,

I have the same problem (for a long time now), but unlike in your case due to the error it takes tens of minutes to boot with 12TB spinning drives in my case.

Others have the problem too, see:
https://jira.ixsystems.com/browse/NAS-105093
https://forums.freebsd.org/threads/gptzfsboot-error-128-after-adding-new-disks.65677/

The issue is unsolved (and trueNAS engineering closed it as such) AFAIK.

Best regards,
Peter
