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

>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
