Is there something like tools/diag/prtblknos for ZFS?
zdb.
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:
[snip]
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.
