Hi all,

I asked this of mkp but he doesn't know off the top of his head: is there a
limit to the XFS fs size?  I've tried creating one on just over 1.1TB with
no success:

[root@sdssdp6 /]# fdisk -l /dev/md6
    Device Boot    Start       End    Blocks   Id  System
/dev/md6p1             1 280147712 1120590846   83  Linux

[root@sdssdp6 /]# mkfs.xfs /dev/md6 
mkfs.xfs: can't get size for data subvolume
Usage: mkfs.xfs
/* blocksize */		[-b log=n|size=num]
/* data subvol */	[-d agcount=n,agsize=n,file,name=xxx,size=num,
			    sunit=value,swidth=value,unwritten=0|1,
			    su=value,sw=value]
/* inode size */	[-i log=n|perblock=n|size=num,maxpct=n]
/* log subvol */	[-l agnum=n,internal,size=num,logdev=xxx]
/* naming */		[-n log=n|size=num|version=n]
/* label */		[-L label (maximum 12 characters)]
/* prototype file */	[-p fname]
/* quiet */		[-q]
/* version */		[-V]
/* realtime subvol */	[-r extsize=num,size=num,rtdev=xxx]
			devicename
<devicename> is required unless -d name=xxx is given.
Internal log by default, size is scaled from 1,000 blocks to 32,768 blocks
based on the filesystem size.  Default log reaches its largest size at 1TB.
This can be overridden with the -l options or using a volume manager with a
log subvolume.
<num> is xxx (bytes), or xxxb (blocks), or xxxk (xxx KB), or xxxm (xxx MB)
<value> is xxx (512 blocks).


>From recent comments made by Steve,
(http://oss.sgi.com/projects/xfs/mail_archive/0107/msg00727.html) it sounds
that since I'm trying to make a fs with inode numbers > 32 bits, I might be
hosed.  

FWIW, I'm using 2.4.5 kernel with R1.0.1.

Thanks,
Dan
