FreeBSD升级后,添加用户出错adduser: ERROR: There was an error adding user
需要:
zpool upgrade -a
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0

比如hp的dl380g5服务器,raid的逻辑盘在linux中不是/dev/sda而是/dev/cciss/c0d0,mmcrnsd的时候正常,但是mmcrfs的时候报错“Unable to open disk”,使用mmlsnsd -m则有如下显示:
Disk name NSD volume ID Device Node name Remarks
—————————————————————————————
io00nsd01 0A01C866666C04EB – io00 (not found) server node
解决方法:
cp /usr/lpp/mmfs/samples/nsddevices.sample /var/mmfs/etc/nsddevices
vim /var/mmfs/etc/nsddevices
在$osName = Linux 增加 echo "/dev/cciss/c0d0p4 generic",取消最后return 1的注释,echo中的/dev/cciss/c0d0p4必须和你的nsd描述文件中的device完全一致
chmod +x /var/mmfs/etc/nsddevices
测试环境:IBM HS22 X5650 24Gram Chelsio T420-BCH 关闭超线程 两台,BNT Virtual Fabric 10Gb Switch Module for IBM BladeCenter 两台,RHEL 6.3,ChelsioUwire-2.2.0.0,iperf 2.0.5 (08 Jul 2010) pthreads
详细测试结果见下面的表格,显而易见,万兆TOE还是非常有必要的,否则光对10GB的TCP流量进行基本处理就耗尽CPU资源了。
升级说明中有一点要求是:Please rebuild all installed 3rd party software
应该执行的命令是:portmaster -Raf
对于ZFS root的系统,升级完成重启前需要重写所有的硬盘的boot
gpart bootcode -b /boot/pmbr -p /boot/gptzfsboot -i 1 da0
samba报错smbd’s max open files = 16384
一般是系统的open flies限制
查看系统限制:
[root@storage ~]# sysctl -a | grep maxfiles
kern.maxfiles: 12328
kern.maxfilesperproc: 11095
kern.openfiles: 8760
FreeBSD 8.2,默认系统打开文件数12328,每进程打开文件数11095,kern.openfiles是系统当前打开文件数。
设置新的系统限制:
[root@storage ~]# sysctl kern.maxfiles=65536
[root@storage ~]# sysctl kern.maxfilesperproc=32768
查看某个进程的系统限制,nofile就是这个进程打开文件数的限制
24443是某个smbd的pid
[root@storage ~]# mount -t procfs proc /proc
[root@storage ~]# cd /proc/24443
[root@storage /proc/24443]# ls -l

/etc/login.conf可以配置某个用户的系统资源限制,默认是无限制的,就是受限于系统内核限制
/etc/sysctl.conf里面配置对开机启动的服务无效
/boot/loader.conf里面配置对开机启动的服务有效
debian 6.0.0 安装的时候只选了Standard system utilities,虽然在安装过程中不认识vmxnet3网卡,但是安装完成后即使没有安装VMware Tools,debian也是可以识别vmxnet3网卡的。
编辑/etc/apt/sources.list,把原来的都注释了,加入下面的内容
deb http://ftp.cn.debian.org/debian squeeze main
deb-src http://ftp.cn.debian.org/debian squeeze main
deb http://ftp.cn.debian.org/debian squeeze-updates main
deb-src http://ftp.cn.debian.org/debian squeeze-updates main
deb http://mirrors.ustc.edu.cn/debian-security/ squeeze/updates main
deb-src http://mirrors.ustc.edu.cn/debian-security/ squeeze/updates main
在安装VMware Tools之前还需要执行 aptitude install make linux-headers-2.6-amd64 来安装gcc make linux-headers等,可喜的是这些都在CD1上就有。
安装mysql的不要忘记运行一下mysql_secure_installation
домейнYou need base, sys, and sbin sources if you are going the sysinstall route. If you look in the fusefs-kmod Makefile:
显示当前目录下的所有目录 ls -d */
显示/dev下的所有目录 ls -d /dev/*/
神奇啊
直到VMware ESX(i) 4.0 U2,官方的VMware-tools都未提供对FreeBSD 8.0 amd64的支持,因此改为安装Open Virtual Machine Tools。
[root@yaoge123 ~/vmware-tools-distrib]# uname -a
FreeBSD yaoge123 8.0-RELEASE-p3 FreeBSD 8.0-RELEASE-p3 #0: Tue May 25 20:54:11 UTC 2010 root@amd64-builder.daemonology.net:/usr/obj/usr/src/sys/GENERIC amd64
[root@www ~/vmware-tools-distrib]# ./vmware-install.pl
Creating a new VMware Tools installer database using the tar4 format.
Installing VMware Tools.
……
Before running VMware Tools for the first time, you need to configure it by
invoking the following command: “/usr/local/bin/vmware-config-tools.pl”. Do you
want this program to invoke the command for you now? [yes]
Initializing…
Stopping VMware Tools services in the virtual machine:
Guest operating system daemon: done
Unable to copy the source file
/usr/local/lib/vmware-tools/modules/binary/FreeBSD8.0-amd64/vmxnet.ko to the
destination file /boot/modules/vmxnet.ko.
Execution aborted.

首先确认是否安装了内核源代码,如果您的系统中没有 /usr/src/sys 这样一个目录, 则说明没有安装内核源代码。安装它最简单的方法是通过以 root 身份运行 sysinstall, 选择 Configure – Distributions – src,选中其中的 base 、sbin和sys。如果提示Warning: Can’t find the `8.0-RELEASE-p3′ distribution on this……,在Configure – Distributions – Options中修改Release Name为8.0-RELEASE,安装完成后用freebsd-update fetch install更新源代码。
然后再安装Open Virtual Machine Tools
cd /usr/ports/emulators/open-vm-tools-nox11
make install clean
至少支持了使用VMware Tools关机(这是HA所必不可少的)和vmxnet2网卡。
/usr/target /usr/mount-point nullfs rw,late 0 0
注意必须在Options中添加“late”,否则启动的时候报错。
