Hi list,
I have a HW raid 5 array with chunck size 256KB and stripe size 2560KB.
Basically a 10+1+1 array. 10 drives, one parity, one spare.
I am trying to create an xfs file system with the appropriate sunit and
width.
# mkfs.xfs -d sunit=512,swidth=5120 -f /dev/mapper/mpath9
meta-data=/dev/mapper/mpath9 isize=256 agcount=32,
agsize=56652352 blks
= sectsz=512 attr=0
data = bsize=4096 blocks=1812874752,
imaxpct=25
= sunit=64 swidth=640 blks,
unwritten=1
naming =version 2 bsize=4096
log =internal log bsize=4096 blocks=32768, version=1
= sectsz=512 sunit=0 blks
realtime =none extsz=65536 blocks=0, rtextents=0
As you can see the sunit gets set to 64 upon creation and not 512 like I
asked. Also if it try to give it some mount options it does the same
thing.
sgi210a:~ # mount -o sunit=512,swidth=5120 /dev/mapper/mpath9 /mnt/
sgi210a:~ # xfs_info /mnt/
meta-data=/dev/mapper/mpath9 isize=256 agcount=32,
agsize=56652352 blks
= sectsz=512 attr=0
data = bsize=4096 blocks=1812874752,
imaxpct=25
= sunit=64 swidth=640 blks,
unwritten=1
naming =version 2 bsize=4096
log =internal bsize=4096 blocks=32768, version=1
= sectsz=512 sunit=0 blks
realtime =none extsz=65536 blocks=0, rtextents=0

Any ideas?
Last I tried to subscribe to the list by sending email to
ecartis@xxxxxxxxxxx a couple of times but was unsuccessful should I send
email elsewhere to subscribe?
thank you
