Related, more logical errors on my side probably:

Can someone give me a hint what I'm doing wrong here?

xfs_bmap -l  /local/boinc/time_stats_log
/local/boinc/time_stats_log:
        0: [0..127]: 280..407 128 blocks
        1: [128..159]: 728..759 32 blocks
        2: [160..167]: 1016..1023 8 blocks
        3: [168..183]: 54120..54135 16 blocks
        4: [184..207]: 656..679 24 blocks
        5: [208..215]: 3451664..3451671 8 blocks
        6: [216..255]: 3451624..3451663 40 blocks
        7: [256..287]: 3451672..3451703 32 blocks

>From that I assume that this file lives in several block strips, when I
subsequently try to get this back via xfs_db I fail miserably:

xfs_db -i /dev/sda6
xfs_db> blockget -b 660 -n
setting block 0/660 to data
setting inode to 2787 for block 0/660
inode 2787 block 660 at offset 346
xfs_db> ncheck -i 2787
       2787 CT_oneyear_01/S_noise_wu_84/Fstats_105.25_Snoise__WU84_84_out
xfs_db> quit

Is it possible that blocks != bsized_blocks?

Sorry for these questions, but I'm quite lost and I have not been able
to find the answer in the man pages.

Cheers

Carsten
