Hello,
Please provide me an advice on the following issues;
I'd like to use 4k block size for both MD super block I/O and regular file
I/O,
which will improve the performance.
Q1: I noticed that it set the "blksize_size" to 4k for MD SB I/O but it use
1K
for the regular file I/O. It usually set the size to 1k at system
init by "md-init",
then it set to 4k for MD SB I/O later. I could not find the place
that set it
back to 1k. However, it changes to 1 k???? How?
Q2: I modified md.c to use the 4k blksize_size. It works but sometimes it
crash.
System "BLOCK_SIZE" is still 1k, and my hd device blksize_size=1k,
too.
I changed ONLY 1024 to 4096 on every occurences on md.c.
What am I missing?
Thanks in advance,
Bo
