Setup lvm

combine /dev/sdb and /dev/sdc

if there’s partition on /dev/sdb, /dev/sdc, need to clear them first using fdisk

fdisk /dev/sdb -> d (delete partition) ->w

fdisk /dev/sdc

pvcreate /dev/sdb

pvcreate /dev/sdc

vgcreate vgrp /dev/sdb /dev/sdc

vgchange -a y vg

vgdisplay vg|grep ‘Total PE’
lvcreate -i2 -I8 -l 70006 vg -n lv

vgdisplay vg|grep ‘Total PE

‘lvcreate -i2 -I8 -l 70006 vg -n lv

mkfs.ext3 /dev/vg/lv

tune2fs -r 128000 /dev/vg/lv

mount /dev/vg/lv /backup

Remove lvm

#lvremove /dev/vg/lv
#vgremove vg
#fdisk /dev/sdb
#mkfs.ext3 /dev/sdb1
#tune2fs -r 128000 /dev/sdb1
(do same to /dev/sdc)
#mount /dev/sdb1 /www

problem in search

problem when search for “V&R”
V%26amp%3BR
%26 -> &
%3B -> ;
%26amp%3B -> &

Solution: change & to encoded code in query sent to html
Add:
$srch_name=eregi_replace(“&”,”%26amp%3B”,$srch_name);
before the following code
if($srch_name !=”){ $req.=”&name=$srch_name”; }
if($srch_site !=”){ $req.=”&site=$srch_site”; }
