Description Oliver Scheck 2003-01-26 16:16:31 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i586; en-US; rv:1.2) Gecko/20021203

Description of problem:
Both /usr and / are mounted from an NFS server.

At reboot or shutdown the script netfs fails because both rc and netfs
are still using /usr and are therefore killed by netfs itself.
rc and netfs use the following files from /usr:

/usr/lib/gconv/gconv-modules.cache
/usr/lib/gconv/ISO8859-1.so
/usr/lib/locale/locale-archive

Disabling usage of locales for these scripts solve the problem (see
patches for rc and netfs).

Furthermore netfs incorrectly tries also to umount the NFS / filesystem instead
of explicitely leaving it mounted (see patch for netfs).

Version-Release number of selected component (if applicable):
initscripts-6.95-1

How reproducible:
Always

Steps to Reproduce:
1. Rebuild linux kernel for root filesystem on NFS
2. Mount / and /usr from an NFS server
3. Shutdown or reboot the system
    

Actual Results:  netfs kills processes using /usr (rc and netfs use /usr):

INIT: no more processes left in this runlevel


Expected Results:  Unmounting of NFS filesystems and proper system reboot/shutdown.

nfs umounts: use nohup/bg when calling fuser -mk

 if your nfs mount is so badly hosed that any process trying to access mounted
dir hangs in a D state, netfs hangs itself by calling fuser.
 fix: send fuser -mk to background; system is left with extra 3 hanging fuser
processes, but continues to do down.
 reason to user nohup, in interactive shell (netfs called manually) hanging
fuser probably will stay attached to your terminal which is not a very good
thing.

Comment 4 Bill Nottingham 2003-09-04 01:57:42 UTC
The first two patches break locale in general for  messages, which is not good.
The third is the same problem in bug #63602.
