Hi,
On a new machine, I have rebuilt the XFS 1.1 PR2 kernels, adding the LVM
patch posted by Eric late last week and enabling LVM support in the build.
I have installed the XFS 1.1 PR2 cmd_rpms also.
I have a single LVM volume on hardware RAID 5 (9 disks, 64kB chunk size),
and am trying the mkfs command:
# mkfs.xfs -f -d sw=9,su=64k /dev/vg/lv
Firstly, is this the right sw/su combination for this RAID configuration?
I've seen this asked before, but can't find any obvious answer in the
mailing list archives nor anything in the FAQ - sorry for repeating it.
Secondly, upon running the mkfs I see the warning message shown below before
the filesystem is created:
mkfs.xfs: warning - cannot set blocksize on block device /dev/vg/lv: Invalid
argument
meta-data=/dev/vg/lv isize=256 agcount=125, agsize=1048576 blks
data = bsize=4096 blocks=131072000, imaxpct=25
= sunit=16 swidth=144 blks, unwritten=0
naming =version 2 bsize=4096
log =internal log bsize=4096 blocks=16000
realtime =none extsz=65536 blocks=0, rtextents=0
Is this anything to worry about? I know it says "warning", but I thought I
read somewhere that all the warnings that weren't evil were going to be
hidden by default before the 1.1 release. Has this been overlooked, or is
it something to worry about?
Thirdly this machine will be used primarily as a NFS server; is there any
advantage in increasing the log sizes here?
Thanks in advance,
Chris
