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 sgi210a:~ # Any ideas? Last I tried to subscribe to the list by sending email to ecartis@oss.sgi.com a couple of times but was unsuccessful should I send email elsewhere to subscribe? thank you Rene
