Hi,
I am creating XFS filesystem on a 750Gb partition, which is made up of
4x250Gb WD disks in RAID-5 + 3ware card. System is RH9.0 with 2.4.23
kernel and xfs patch as of 031010 from the oss.sgi site.
I collected all the useful info from the manual and from the list, but
would like to make sure if I am doing the correct thing:
mkfs.xfs -b size=4k -d su=64k,sw=3 -f -i size=512 -l su=64k,size=32m -L
BIG /dev/sda1
The raid-5 stripe size is 64k, fixed.
xfstools is 2.6.2, from atrpms site.
meta-data=/dev/sda1 isize=512 agcount=32, agsize=5723344
blks
= sectsz=512
data = bsize=4096 blocks=183147008, imaxpct=25
= sunit=16 swidth=48 blks, unwritten=1
naming =version 2 bsize=4096
log =internal log bsize=4096 blocks=8192, version=2
= sectsz=512 sunit=16 blks
realtime =none extsz=65536 blocks=0, rtextents=0
------------------
hdparm -tT /dev/sda
/dev/sda:
Timing buffer-cache reads: 128 MB in 0.20 seconds =640.00 MB/sec
Timing buffered disk reads: 64 MB in 1.55 seconds = 41.29 MB/sec
It is OK, but I am not shocked by the performance.
Are there any recommended tests to test the filesystem before starting to
populate it with all that 750Gb of data?
All the best
Gaspar
