Description of problem:
bz 170714 introduced a fix to allow more nfs mounts to be established. This
solution however, assumed the availability of util-linux-2.11y-31.14, which
contains a fix to allow mount to always use UDP first when contact the mountd
rpc program daemon. Without this fix in place, the fix in bz 170714 actually
causes a regression in the number of supported mounts over nfs.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.attempt to mount 1024 nfs mounts under RHEL3 U4 and RHEL3 U7
RHEL3 U4 mounts >= 800 nfs mount
RHEL3 U7 mounts == ~512 nfs mounts
Removing CANFIX blocker... this has not gone through ACK process.
Hmm.. there is some unreleased patch:
* Wed Oct 19 2005 Steve Dickson <firstname.lastname@example.org> 2.11y-31.13
- fix #170714 Changed nfsmount to first try the UDP transport when
querying the remote rpc.mountd, then tcp iff tcp is
specified. This tremendously increases the total number
of tcp mounts that can occur.
I think (hope) this patch resolve the problem. It means we needn't rebase anything.
