Install OCZ RevoDrive3X2 on Ubuntu 12.04 x64 with kernel 3.2.0-23-generic

默认情况下Ubuntu 带的mvsas驱动可以将OCZ RevoDrive3X2驱起来, 但是性能不怎么样, 并且一块240G的盘在系统中会被认成2块120G的盘.

详见如下文章 :

实际上OCZ有Ubuntu下的驱动, 本文介绍一下如何安装这个驱动.

首先要下载驱动, 在OCZ网站上找到12.04对应的驱动,

http://ocz.com/enterprise/download/drivers

Ubuntu 12.04 64-bit

3.7.6.3912

3.2.0-23-generic

Dec 19, 2012

202KB

注意它的内核版本是3.2.0-23-generic的. 操作系统为64位.

如果你用的是12.04 x64的版本, 但是内核版本对不上的话, 首先要加载这个内核.

检查当前版本.

uname -a

如果不是 3.2.0-23-generic, 那么看一下/boot中有没有这个内核版本.

cd /boot
ls -la

如果在这个目录中没有对应的内核版本, 那么需要重新安装这个内核.

首先要查看内核包名称

root@digoal-PowerEdge-R610:~# apt-cache search linux-image|grep generic
linux-image-3.2.0-23-generic - Linux kernel image for version 3.2.0 on 64 bit x86 SMP

包的名称为 linux-image-3.2.0-23-generic

然后安装这个包

apt-get install linux-image-3.2.0-23-generic

安装完后需要调整grub.cfg, 让系统以这个内核引导 :

vi /boot/grub/grub.cfg

### BEGIN /etc/grub.d/00_header ###
if [ -s $prefix/grubenv ]; thenset have_grubenv=trueload_env
fi
set default="2>2"

解释一下这里设置的2>2, 第一个2表示第一级别菜单, 第二个2表示该主菜单中的子菜单.

以0开始编号.

对应的菜单如下 :

menuentry 'Ubuntu, with Linux 3.5.0-26-generic' --class ubuntu --class gnu-linux --class gnu --class os {recordfailgfxmode $linux_gfx_modeinsmod gzioinsmod part_msdosinsmod ext2set root='(hd0,msdos1)'search --no-floppy --fs-uuid --set=root 8c78d733-7f2c-49b5-81c8-2ebf2af45979linux   /boot/vmlinuz-3.5.0-26-generic root=UUID=8c78d733-7f2c-49b5-81c8-2ebf2af45979 ro   quiet splash $vt_handoffinitrd  /boot/initrd.img-3.5.0-26-generic

}
# 第一级=2的如下

}
# 第二级=2的如下 :

}
}

在修改完/boot/grub/grub.cfg后重启操作系统.

重启完检查当前内核版本是否正确 :

root@digoal-PowerEdge-R610:/boot# uname -a
Linux digoal-PowerEdge-R610 3.2.0-23-generic #36-Ubuntu SMP Tue Apr 10 20:39:51 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

接下来就可以下载对应的驱动了 :

wget http://ocz.com/enterprise/download/drivers/OCZ_Ubuntu_12.04_64-bit_3.7.6.3912.tar.gz

解压并将其拷贝到对应的目录.

tar -zxvf OCZ_Ubuntu_12.04_64-bit_3.7.6.3912.tar.gz
cp ocz10xx.ko /mnt/lib/modules/3.2.0-23-generic/kernel/drivers/scsi/mvsas/

在确保没有其他盘用到mvsas驱动的前提下, 移除当前mvsas驱动. (使用lspci -k -vvvv|less 查看这个驱动是不是只有OCZ PCI-E在使用)

rmmod -f mvsas

将mvsas加入黑名单

vi /etc/modprobe.d/blacklist.conf
blacklist mvsas

建立模块依赖列表

depmod -a

查看

root@digoal-PowerEdge-R610:/boot# grep ocz /lib/modules/3.2.0-23-generic/modules.dep
kernel/drivers/scsi/mvsas/ocz10xx.ko:

插入ocz10xx模块

modprobe ocz10xx

将ocz10xx加入initramfs

vi /etc/initramfs-tools/modules

确保/etc/initramfs-tools/modules文件中有如下行

ocz10xx

重建initramfs, 更新所有内核版本

update-initramfs -u -k all -v > /tmp/output.txt

重启操作系统.

重启后查看是否使用了ocz10xx驱动. 如下当前使用的是ocz10xx驱动, mvsas已经加入黑名单了.

root@digoal-PowerEdge-R610:/boot# lspci -k -vvvv|grep ocz10xxKernel driver in use: ocz10xxKernel modules: ocz10xx, mvsasKernel driver in use: ocz10xxKernel modules: ocz10xx, mvsas

[其他]

1. 如果一切使用了mvsas, 由于磁盘被分割成了2块盘, 如果在使用mvsas时创建了pv, 会出现异常如下.

root@digoal-PowerEdge-R610:/boot# pvsCouldn't find device with uuid nnedB0-oBoS-PZZ2-ZyVK-yyE5-T9dN-xcEz8C.Couldn't find device with uuid Od1c6B-i2Ow-HFM1-i7Wf-HtzK-9R22-2VHArf.PV             VG       Fmt  Attr PSize   PFree/dev/sdb       vgdata01 lvm2 a-   185.75g    0 /dev/sdc       vgdata01 lvm2 a-   476.37g    0 /dev/sdd       vgdata01 lvm2 a-   111.79g    0 /dev/sde       vgdata01 lvm2 a-   111.79g    0 unknown device vgdata01 lvm2 a-   111.79g    0 unknown device vgdata01 lvm2 a-   111.79g    0

修复方法 :

删除lvm cache文件.

root@digoal-PowerEdge-R610:/boot# rm /etc/lvm/cache/.cache
rm: remove regular file `/etc/lvm/cache/.cache'? y

移除丢失的pv

root@digoal-PowerEdge-R610:/boot# vgreduce --removemissing vgdata01Couldn't find device with uuid nnedB0-oBoS-PZZ2-ZyVK-yyE5-T9dN-xcEz8C.Couldn't find device with uuid Od1c6B-i2Ow-HFM1-i7Wf-HtzK-9R22-2VHArf.Wrote out consistent volume group vgdata01

重建vg

root@digoal-PowerEdge-R610:/boot# vgremove vgdata01Volume group "vgdata01" successfully removed
root@digoal-PowerEdge-R610:/boot# pvremove /dev/sddLabels on physical volume "/dev/sdd" successfully wiped

root@digoal-PowerEdge-R610:/boot# pvremove /dev/sdcLabels on physical volume "/dev/sdc" successfully wiped

移除pv后, 新建分区时注意使用1MB对齐 :
