zdb params more details

[httaotao]

Hi, here I have installed openzfs

# zfs --version
zfs-2.1.6-0york1~20.04
zfs-kmod-0.8.3-1ubuntu12.14

However, I don't know how to use zdb with -R

For example, here are zpool and dataset info

# zfs list 
NAME        USED  AVAIL     REFER  MOUNTPOINT
zp01       8.17M  18.9G       24K  /zp01
zp01/zd01  8.03M  18.9G     8.03M  /zp01/zd01

# stat /zp01/zd01/vdbench50407.tar

# zdb -d zp01/zd01 128
Dataset zp01/zd01 [ZPL], ID 136, cr_txg 41, 8.03M, 8 objects

How can i use zdb -R to print indirect block info? thanks

By the way, Does zdb can print file struct more details, like

# xfs_db -c "inode 131" -c "p" /dev/vdh
core.magic = 0x494e
core.mode = 0100644
core.version = 3
core.format = 2 (extents)
core.nlinkv2 = 1
core.onlink = 0
core.projid_lo = 0
core.projid_hi = 0
....

xfs_db

I am curious about the zfs file struct. So sometimes I want to use zdb to print more internal info, thanks
