在我的环境中，我的实验室中有一台 Citrix Xen 服务器（5.6 版），在本地分区挂载上安装了多个 VM。上周我到达我的实验室，发现我的虚拟机不见了。本地挂载显示没有数据，就好像有人登录并删除了我的虚拟机一样。服务器处于联机状态且未关闭电源。

我的问题是：使用主机 (/var/logs) 下的本地日志，有什么方法可以告诉您虚拟机已被删除，或者告诉其他一些问题导致服务器丢失？例如，我可以分析 xensource.log 以验证 VM 是否已从主机中删除/删除？或者，是否有另一个日志可以验证我的虚拟机丢失的原因？

乍一看，我以为丢失的服务器陷入了“困境”，例如，发生了重新启动，现在它们被挂起，需要通过控制台关闭。所以，我运行了以下命令：

xe vm-list resident-o​n=<UUID of the XenServer host> --multiple

但是，此命令的结果为空白。我检查了托管数据的分区，它是空的。我没有任何硬件故障（没有故障磁盘或 RAID 问题）。

关于验证我丢失的虚拟机发生了什么的任何想法？非常感谢任何帮助，并在此先感谢

在我的环境中，我有一个运行 CentOS 5 的 linux 服务器。我在该服务器上设置了一个 telnet 服务，以便通过 telnet 进行连接。但是，一段时间后我尝试连接并收到此错误：This session is no longer connected.

一旦我重新启动 xinetd 服务，此消息就会消失，我可以再次 telnet 登录。关于如何调试此问题或我可以查看哪些日志以查看可能导致此错误的任何想法？提前感谢您提供的任何建议或帮助。

在我的环境中，我安装了带有 CUPS 和 SAMBA 的 CentOS 5。我无法从任何机器浏览任何 SAMBA 共享。

在 Windows 8 和 Windows Server 2008 中，我尝试了以下命令

净视图 \\veculx1

网络视图 \\172.19.50.30

但是，我在两个命令上都收到相同的错误：

发生系统错误 53。

找不到网络路径。

从另一台 CentOS 服务器我尝试运行 SMBCLEINT -L \\172.19.50.30

连接到 172.19.50.30 时出错（没有到主机的路由）连接到 172.19.50.30 失败（错误 NT_STATUS_HOST_UNREACHABLE）

ping 服务器解析并回复。我也可以毫无问题地通过 telnet 和 SSH 进入服务器。

运行 testparm smb.conf 显示我的设置没有错误。

以下是 smb.conf 的内容

# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options (perhaps too
# many!) most of which are not shown in this example
#
# For a step to step guide on installing, configuring and using samba,
# read the Samba-HOWTO-Collection. This may be obtained from:
#  http://www.samba.org/samba/docs/Samba-HOWTO-Collection.pdf
#
# Many working examples of smb.conf files can be found in the
# Samba-Guide which is generated daily and can be downloaded from:
#  http://www.samba.org/samba/docs/Samba-Guide.pdf
#
# Any line which starts with a ; (semi-colon) or a # (hash)
# is a comment and is ignored. In this example we will use a #
# for commentry and a ; for parts of the config file that you
# may wish to enable
#
# NOTE: Whenever you modify this file you should run the command "testparm"
# to check that you have not made any basic syntactic errors.
#
#---------------
# SELINUX NOTES:
#
# If you want to use the useradd/groupadd family of binaries please run:
# setsebool -P samba_domain_controller on
#
# If you want to share home directories via samba please run:
# setsebool -P samba_enable_home_dirs on
#
# If you create a new directory you want to share you should mark it as
# "samba-share_t" so that selinux will let you write into it.
# Make sure not to do that on system directories as they may already have
# been marked with othe SELinux labels.
#
# Use ls -ldZ /path to see which context a directory has
#
# Set labels only on directories you created!
# To set a label use the following: chcon -t samba_share_t /path
#
# If you need to share a system created directory you can use one of the
# following (read-only/read-write):
# setsebool -P samba_export_all_ro on
# or
# setsebool -P samba_export_all_rw on
#
# If you want to run scripts (preexec/root prexec/print command/...) please
# put them into the /var/lib/samba/scripts directory so that smbd will be
# allowed to run them.
# Make sure you COPY them and not MOVE them so that the right SELinux context
# is applied, to check all is ok use restorecon -R -v /var/lib/samba/scripts

#

# browser on your network. Otherwise the normal election rules apply

# elections. The default value should be reasonable

#----------------------------- Name Resolution -------------------------------
# Windows Internet Name Serving Support Section:
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both

#
# - WINS Server: Tells the NMBD components of Samba to be a WINS Client
#
# - WINS Proxy: Tells Samba to answer name resolution queries on
#   behalf of a non WINS capable client, for this to work there must be
#   at least one    WINS Server on the network. The default is NO.

# DNS Proxy - tells Samba whether or not to try to resolve NetBIOS names
# via DNS nslookups.

# --------------------------- Filesystem Options ---------------------------
#
# The following options can be uncommented if the filesystem supports
# Extended Attributes and they are enabled (usually by the mount option
# user_xattr). Thess options will let the admin store the DOS attributes
# in an EA and make samba not mess with the permission bits.
#
# Note: these options can also be set just per share, setting them in global
# makes them the default for all shares

我在这里浏览了基本的故障排除指南，但无济于事 https://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/diagnosis.html

我最后一次尝试是尝试从环境中的另一台 SAMBA 服务器复制工作 smb.conf 文件并重新启动 SMB 服务。没有骰子，结果相同。

关于如何确定为什么我无法浏览此服务器上配置的 SAMBA 共享的任何提示或想法？

我在 Citrix XenServer 5.6 上运行 CentOS 5.9 i386。我安装了 3GB 内存、2GB 交换空间的 CentOS。后来我想添加更多内存，所以我关闭了服务器并将 VM 配置为 8GB。重新启动后，服务器仍显示可用内存为 3GB。

我尝试编辑 /boot/grub/grub.conf 并将 mem=xxM 添加到配置中，但是系统仍然报告我只有 3GB 可用内存。

是否有一些我遗漏的配置导致 CentOS 错过了额外的内存？非常感谢任何帮助，并在此先感谢

我正在重建交换环境。以前的管理员没有正确设置存储或系统。话不多说，环境中没有存储，由于其他问题，我们决定搭建一个新的服务器，并将用户迁移到服务器上。

我有 1,500 个用户和 1.4TB 数据库，使用 Exchange 2007 Enterprise。我的新 Exchange 设置总共有 14 个数据库。

新的服务器存储设置将是：

(2) RAID 1 中的 600GB SAS 驱动器（总可用空间为 600GB）。我将有一个分区用于操作系统，一个分区用于事务日志。

(10) RAID 10 中的 600GB SAS 驱动器。这将用于数据库，总共 3TB 存储。

额外：如果需要，我还有四个剩余的 SAS 插槽可以在将来添加更多存储空间。

我的问题：你会推荐不同的设置，还是这个设置听起来最优？有什么建议么？提前致谢并致以最诚挚的问候

在我的环境中，我在 CCR 集群中设置了 Exchange 2007，以被动模式将我们的主服务器镜像到一组服务器。我为 Exchange 2007 的日志设置的被动节点上的分区之一出现故障，导致分区不可读。我已经更换了被动节点上的分区，并将驱动器设置为在主动模式下镜像分区，但自更改后日志没有复制。

无论如何强制将日志的新驱动器复制到新分区？知道为什么日志不复制吗？

感谢您提供任何帮助或意见，并提前致谢。

我被分配了一项任务，通过导出离开公司的用户的邮箱来清理我们的 Exchange 服务器。我们希望将邮箱的副本保留 90 天，以防 HR 或管理层以后需要它。我有 130 多个邮箱要导出以完成此任务。

我看到将邮箱导出到 PST 的唯一方法是通过 Exchange 管理工具使用 Export-Mailbox cmdlet。我的问题是：是否有一个脚本可以让我批量执行此操作？也许将电子邮件地址传递到文件中并运行脚本？这将很有帮助，可以减少完成此任务所需的时间。

在此先感谢您的任何建议或帮助！！

我在 unix 上有一个 Data General 服务器，它在每次打印时都打印一个标题页。我原本以为标题页来自打印机。由于这是 HP 打印机，我使用 telnet 访问 jetadmin，然后继续禁用标题页，但这并没有解决问题。

然后我进入 sysadm 程序查看 TCPIP 打印是否设置为在打印作业中打印标题页，但我没有看到任何打印标题页的选项。

关于如何在 unix 中禁用横幅页打印的任何帮助或想法？

在我的环境中，我有 Exchange 2007、具有 2 MB、2 HT 和 2 CAS 服务器的 ccr 环境。我们目前使用 Outlook 2010 作为终端服务器的电子邮件客户端。客户端配置为直接连接到交换，而不是缓存模式。

最近，我们的用户抱怨 Outlook 2010 的速度和性能，例如当他们选择一个文件夹时，服务器需要几分钟时间才能让文件夹显示项目。有时 Outlook 会在等待加载时冻结，并且需要几分钟才能解冻。

我可以尝试诊断导致此问题的原因的任何故障排除想法吗？
