take sdb as newly added disk

Step1: Format new disk and label as LVM disk
fdisk /dev/sdb
n -> p -> 1 -> return twice -> t -> 8e -> w

Step2: Create FS on new disk
mkfs.ext3 /dev/sdb1

Step3: Create as PV
pvcreate /dev/sdb1

Step4: Extend existing VG to new disk
vgextend VolGroup00 /dev/sdb1
then, you will get more free space now. check with:
vgs

Step5: Extend the Vol
lvextend -L +total_space_for_vol_g /dev/VolGroup00/LogVol00
lvextend -L +space_number_to_add_g /dev/VolGroup00/LogVol00

Step6: Online resize the Vol
resize2fs /dev/VolGroup00/LogVol00

Step7: Done.

All following update /etc/vsftpd/vsftpd.conf

How to change the default public root ?
anon_root=/the/path/you/want

I don’t want let my firewall too open. then define the min/max port.
pasv_min_port=60000
pasv_max_port=65000

iptable setting. 20 is for data
# for FTP
-A INPUT -m state –state NEW -m tcp -p tcp –dport 20 -j ACCEPT
-A INPUT -m state –state NEW -m tcp -p tcp –dport 21 -j ACCEPT
-A INPUT -m state –state NEW -m tcp -p tcp –dport 60000:65000 -j ACCEPT

Vsftp default turn Passive on, How to disable it ?
pasv_enable=NO

ENABLED SYNC could happened when you do the vxassist and then ctrl+c incidently.

Solution:
vxvol -g rootdg -f resync oravol

this need wait a while.

no verbose progress shows up. you can check with following.
vxprint -g rootdg -l|grep -i sync
state: state=SYNC kernel=ENABLED cdsrecovery=2/2 (syncing)

Another tips:
df -h can’t find the change for vxresize. but vxprint shows up.
you can use fsadm -b to extend the fs.

Env, use Xming as X server. and foward Oracle X to Xming.
$export DISPLAY=192.168.1.103:0.0
$dbca
Warning: Cannot convert string “-b&h-lucida-medium-r-normal-sans-*-140-*-*-p-*-iso8859-1″ to type FontStruct

Note, the Warning is the killer. which stopped dbca go foward

You may check the trace log. every time you click the finish, it will show, FinishClicked: true
/app/oracle/product/10.2.0/db_1/cfgtoollogs/dbca/trace.log
[AWT-EventQueue-0] [10:45:2:543] [DBCAWizard.onFinish:1139] m_bFinishClicked: true

to fix it:
1. install the Xming-fonts which can be downloaded from Xming site.
2. use Linux computer as the X server.

Btw, you may met issue with X in linux.
X :0 -nolisten tcp
it doesn’t change even you updated the /etc/X11/xinit/xserverrc.
try this
add following lines to /etc/gdm/custom.conf

[security]
DisallowTCP=false

and reboot the computer. or restart gdm.

Step 1.
create VM with 2 drives. c0t0d0 & c0t1d0

Step 2.
Duet to hardware limit, we use x86, Install Solaris 10 with option 4. install with Text console. we install OS on one disk

Step 3.
Create SVM

3.1 create the same disk layout as rootdisk,
prtvtoc /dev/rdsk/c0t0d0s2|fmthard -s – /dev/rdsk/c0t1d0s2

3.2 initialize the metadb, depends the layout you have. choose two slice for the meta store.
metadb -a -f -c 2 c0t0d0s3 c0t1d0s3
metadb
flags first blk block count
a m p luo 16 8192 /dev/dsk/c0t0d0s3
a p luo 16 8192 /dev/dsk/c0t1d0s3

3.3 install grub to the s0 for / ? (maybe not nessary to solaris 10)
installgrub /boot/grub/stage1 /boot/grub/stage2 /dev/rdsk/c0t1d0s0

3.4 create mirror for /
# metainit -f d10 concat/stripe numstripes slice
metainit -f d10 1 1 c0t0d0s0
metainit -f d20 1 1 c0t1d0s0

# metainit mirror -m submirror
metainit d0 -m d10

# create root on the mirror, this will update /etc/vfstab and /etc/system let the boot use d0
metaroot d0

3.5 after that reboot — -r, then attach d20 to the mirror.
metattach d0 d20

3.6. do the same on /var

Issue and tips;
# mount cd on solaris
iostate -En #get the cdrom
mount -F hsfs -o ro /dev/dsk/c1t0d0s0 /mnt
or
mount -F hsfs -r /dev/sr0 /mnt

# swap off the swap device
swap -d /dev/dsk/c0t0d0sx

vxdisk list c2t0d63s2
Multipathing information:
numpaths: 2
c2t0d63s2 state=disabled
c3t0d63s2 state=disabled

vxdmpadm enable path=c2t0d63s2
vxdmpadm enable path=c3t0d63s2

then it goes to
numpaths: 2
c2t0d63s2 state=enabled
c3t0d63s2 state=enabled

Solution:
set the /boot/grub path
root@ubuntu:~# mkdir /a; mount /dev/sda1 /a # sda1 is the root you installed linux
root@ubuntu:~# grub-install /dev/sda –boot-directory=/a/boot/grub
Installation finished. No error reported.

Puppet vs Chef vs Cfengine

Solution:
rpm -qi ruby
Name : ruby Relocations: (not relocatable)
Version : 1.8.7.299 Vendor: AegisCo
then get the source package with the same version.
cd /usr/src/redhat/SOURCES/ruby-1.8.7-p299/ext/openssl/
ruby extconf.rb
make
make install
