mount hang with mount nfs share
Last modified: 2007-11-16 20:14:55 EST
Description of problem:
when I tried to mount lustre FS exported via nfs - mount hang in data wait state.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. create device with major or minor number over 256 and export via nfs.
bug exist in both kernel and nfs tools.
first bug in nfs-tools,
nfs-tools can`t be read fsid type 3 from kernel hash - nfsd.fh and grop request
without any error message. for fix this function nfsd_fh in utils/mount should
be updated from lastes version (i test with 1.0.10).
second bug exist in fs/nfsd/export.c - he also drop fsid type 3 from tools.
this fixed with small patch (get from 2.6.16 kernel)
