Is there something like tools/diag/prtblknos for ZFS?


It has a manual page, but in the case like this you typically want to run
zdb -d[d*] <ZFS filesystem name> <file's inode number>
Add d-s until you get all the information you want.

It looks like five d-s is needed to get individual blocks reported.

Thanks for the instructions!

How do I interpret this output:
               0 L1  1:1f01016c000:1000 20000L/1000P F=3 B=16769122/16769122                0  L0 1:1f00f9e3000:20000 20000L/20000P F=1 B=16769122/16769122            20000  L0 1:1f00fa03000:20000 20000L/20000P F=1 B=16769122/16769122            40000  L0 1:1f00fa23000:20000 20000L/20000P F=1 B=16769122/16769122
The first number is an offset within the file (hex); Lx is a block level where L0 is a data block, L1 is an indirect block just above data blocks, etc; x:y:z is a (top-level) vdev number, a block offset on disk (hex) and a block size on
disk(hex); the rest is not as important.
The quoted offsets appear to be just below 2TB.

Are these byte addresses?  Or do I need to multiply by the blocksize to determine the offset into the file?  From your "just below 2TB" I'm assuming byte addresses.

This is a supermicro board X10SRA. They do have a f/w update,
but I suspect it is mainly just for new ucode.  Of course there is
no changelong.  I guess I'll try it if/when I'm totally unable to
boot into a new BE.

I just checked, and my EFI loader is ~1 year old, I should probably try
updating that too.

FWIW, I just updated to head again, and I see a problem with just one
module, which looks like the attached.

could you test https://reviews.freebsd.org/D15207

Thank you so much! I just tried that, and I'm afraid that it didn't help, though by all rights I'd expect that it should. I installed the
world into a new BE, and made sure to re-install boot1.efi into all
my EFI partitions.

Are you able to replicate this issue yourself?
