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:
