/vicepa isn't full and isn't reporting physical errors (none are  
reported by the OS, or by a read-only butterfly scan of the disk done  
with fx).  Also, the volumes are teeny and this is a brand new test  
Cell.

     Filesystem             Type  Size   use  avail  %use  Mounted on
     /dev/dsk/dks0d2s7       xfs   17G  836K    17G    1%  /vicepa

So, I did "bos salvage udon a 536870927" and volume 536870927 is now  
gone from the system.

Since this error is about inodes, I used xfs_db to get the options  
set with mkfs_xfs for this filesystem,
     logblocks = 4000
     inodesize = 512
and xfs_size_check had no problem either.

Here's the same done on the next volume that needed salvaging:
