Hi,
I'm writing a small utility to parse XFS fs image on windows.
I'm able to fetch the files in the first AG (0).
However when it comes to the files which are in different AG I'm facing some problem in parsing extent bmap 128bits data of file inode (format == 2).
Here is the sample 128bits data
1. 00 00 00 00 00 00 00 00 00 00 00 04 99 80 00 01 (LSB)
After unpacking the bits are per doc and source code
In the above case I'm getting following
Num Of blocks = 1 (correct) (0 to 20 bits)
absolute block number = 9420 (0x24CC) (wrong) (21 to 72)
file offset = 0 (72 to 126)
I'm always getting wrong absolute block number . Actual data is in block 7628 (0x1DCC).
No matter what I try I'm always getting the same result. I've even verified this
by using the code from xfs_bmbt_get_all function from xfs source which too gives me same result (9420).
Please someone help me with this. I'm stuck on this from 3 days.
Thanks and Regards,
Pradeep
