bug#14251: coreutils-8.15: tail.c : Need support for StorNext file system as distributed file system |

Folks,
my name is Guenter Ressel-Herbert and I'm working in Quantum's StorNext
Sustaining Engineering team.
I have a customer that needs support for tail -f on our StorNext SAN clients.
StorNext (ex cvfs) is a distributed
file system that is bypassing the VFS layer on the client, hence no trigger for
any inotify registration. Seems to
be a common issue for most distributed file systems. Checking out
coreutils-8.15/src/tail.c, I found that
tail -f reverts back to the traditional polling method for all FS's listed in
src/fs-is-local.h returning 0. Would
you please be so kind and add StorNext as distributed file system to that
header file? You also might need
to make up a new #define for the StorNext magic listed below.
StorNext output for fstatfs:
fstatfs(3, {f_type=0xbeefdead, f_bsize=4096, f_blocks=244187136,
f_bfree=242457823, f_bavail=242457823, f_files=1262592, f_ffree=1262483,
f_fsid={1939504002, 317934}, f_namelen=255, f_frsize=4096}) = 0
As you see, the magic is 0xbeefdead.
Thanks a lot!
