Hi
UNIX unlink() syscall doesn't remove the inode if its in use. Its marked to be
unliked when its use count falls to zero. So
6140: 2 x 2GB cache controllers - 4Gbit FC, 16 x 4Gbit 146GB FC 15K spindlesUnfortunately I don't have a 4Gbit HBA or multiple 2Gbit cards, since the above 6140 must be one of the fastest building blocks available. I would have loved to see (using multiple HBA's) how much IO's one could get from
Where can I find information on the file allocation methodology used by ZFS?
Does it use Indexed Allocation?
What strategy does it use to manage the free space on disk? Bit vector,
linked list or something new?
Thanks!
Bret

You've inspired me to blog again:

I'll describe the way we manage free space in the next post.
