Description Klamer Schutte 2002-01-14 09:07:42 UTC
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (Win98; U)

Description of problem:
When installing RedHat 7.2 from a server also running RedHat 7.2 the nfsd deamons on the server all locked with status DW as reported by ps. 
reported system load was high, but system response still OK. Needless to say -- the install didn't work. Point in install process where this 
happened was different on two installs (didn't try more -- NFS server is a production machine, and
needs a reboot after the failure)

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

How reproducible:

Steps to Reproduce:
1. boot NFS server, export tree of RedHat 7.2 disk 1 and 2 (overlayed over each other)
2. boot to-be-installed machine with bootnet.img image
3. select NFS install
4. go through install dialogs

Actual Results:  All nfsd deamons (8 of them) end up in DW state. Before this throughput seems excellent.

Expected Results:  All nfsd deamons should only have the 'D' status when doing actual disk I/O

Additional info:

relevant rpm's (updated from RedHat 7.2 distribution by RedHat errata:)
nfs-utils-0.3.1- (as reported by rpm -qa)

Custom kernel configuration on server
Server is a single CPU Pentium IV 1.7 Ghz
Exported disk is a VFAT file system, on a (fast) IDE disk.
Both network cards support 100Mbit operation
Network cards connected through company hub/switch (I don't know what)

Comment 1 Bob Matthews 2002-01-14 15:49:55 UTC
The current version of nfsd in the kernel does not allow the exporting of FAT
based file systems.  You might want to try copying the ISO's to and EXT3
