[OpenAFS-devel] odd problem with fileserver on irix 6.5

[chas williams]

has anyone else seen this?  if you fill up a server partition to 100% (or 
as near as you can make it) and restart the fileserver it will complain that
you need to remake your filesystems with size=512.  apparently, the check
to see if partitions have appropriately sized inodes tries to call attr_set()
on the mount point.  however, attr_set() fails with ENOSPC on very full 
partitions.  the man page doesnt mention this as one of the possible failures.

i would suggest changing VerifyXFSInodeSize(), to something like the attached
using syssgi(SGI_XFS_FSOPERATIONS,...).  i didnt have time to rebuild the
source with this patch and try it out on my system.  i just deleted 
someone's file to get enough space for the fileserver to 'recognize' the
partition.  i think to think of it as a sacrifice to the gods of afs.
