growfs

[Michael E.Conlen]

Any idea why a growfs to this size works

growfs: 493962.0MB (1011634176 sectors) block size 16384, fragment size 
2048
         using 2688 cylinder groups of 183.77MB, 11761 blks, 23552 
inodes.
         with soft updates
super-block backups (for fsck -b #) at:
  1010881632, 1011257984

but a growfs to

server# growfs -s 1012220000 /dev/da1s1d
We strongly recommend you to make a backup before growing the Filesystem

growfs: rdfs: seek error: 237231962044550260: Unknown error: 0

fails while there is plenty of disk space available. The error doesn't 
seem to make sense and I'm thinking there's some value that's flipped 
out.
