Hello XFS folks:
I would like to know some of detailed design of XFS
implementations.
1. Could anyone please let me know why the log
is distributed among the ag if the log is set to
"internal"?
If I am wrong, please let me know how the log is
generated. (superblock-log-ag-ag-ag... or
superblock-ag(sb...log)-ag(sb..log)-ag(sb...log)...)
which is correct?
2. Regarding the source code,(line 1771: xfs_mkfs.c)
logagno = (xfs_agnumber_t)(agcount / 2);
Could anyone please let me know what the "logagno" is
for? Doesn't this mean log is generated per each ag?
Thanks very much....
