Filesystem Block Size w// DB_BLOCK_SIZE
Hello All,
We're hosting DB1 and DB2 with db_block_size set to 8K, 16K respectively
File system creation is done with mkfs.ocfs2 -b 4K -C 32K -N 4 -L LABLE
/dev/mapper/xxxx
Mount is done with: ocfs2 _netdev,datavolume,nointr 0 0
I'd like to know if we can separate most of the tablespaces on different
LUNs, even if they're on the same disk group sometimes, is it

samsung sata disk pb
...kernel 2.6.27-11),
hdparm -iI is working and benchmark is a lot better :
$ sudo hdparm -tT /dev/sda
/dev/sda:
Timing cached reads: 2392 MB in 2.00 seconds = 1196.00 MB/sec
Timing buffered disk reads: 226 MB in 3.02 seconds = 74.81 MB/sec
the green HD is a 5400rpm, though the other one is 7400rpm, but a factor 2
in performance between them looks very strange to me.
As the green 1 To disk is not identified by hdparm I think it's not
configured properly.
Any hint to make my 1To disk flying like the other one ? :)
cheers,
David
