33. 附录 M：磁盘系统文档生成器

这个 shell 脚本由 Steffen Hulegaard 慷慨提供。以 root (超级用户) 身份运行它，它将生成一个关于你磁盘设置的摘要。在你实施你的设计后运行它，并将结果与你设计的方案进行比较，以检查错误。如果你的系统出现缺陷，这份文档也将成为恢复的有用起点。

# makediskdoc               Collects storage/disk info via df, mount,
#                           /etc/fstab and fdisk.  Creates a single
#                           reference file -- /root/sysop/doc/README.diskdoc
#                           Especially good for documenting storage
#                           config/partioning

# 11/11/1999  SC Hulegaard  Created just before RedHat 5.2 to
#                           RedHat 6.1 upgrade
# 12/31/1999  SC Hulegaard  Added sfdisk -glx usage just prior to
#                           collapse of my Quantum Grand Prix (4.3 Gb)
#
# SEE ALSO  Other /root/bin/make*doc commands to produce other /root/sysop/doc/README.*
#           files.  For example, /root/bin/makenetdoc.
