In Visual LVM, We need to enumerate all disks and volumes to identify LVM information. Now we use the followed scripts
enumerate disk:
#define ENUM_DISK (PCHAR)
“mdcfg=’’;if [ -d /dev/md ];then mdcfg=cat /proc/mdstat;fi;”
“title=fdisk -l|grep dev|head -1|awk '{print $1}';”
“list=fdisk -l|grep $title|grep dev|awk '{print $2}'|sed 's/://'|sed 's@/dev/ram@@'|sed 's@/dev/loop@@';”
“result=’’;”
"for dev in ls /dev/; do "
"[ “echo $list|grep /dev/$dev” != ‘’ ] && "
“[ ! -d /dev/$dev ]&&[ “$mdcfg|awk '{print $1}'|grep $dev” != “$dev” ]&&”
“echo /dev/$dev;”
“done”
enumerate filsystem:
#define ENUM_FORMAT_TYPE (PCHAR)"find /usr/sbin -name 'mkfs.*'|sed 's/\/usr\/sbin\/mkfs.//';find /sbin -name 'mkfs.*'|sed 's/\/sbin\/mkfs.//'"
and enumerate parts available(for blue print):
#define ENUM_METHOD (char*)"list=fdisk -l|grep “/dev”|awk ‘{print $1}’|grep “/dev/”;lvs|awk ‘{print “/dev/”$2"/"$1}’|sed ‘1d’;echo \"$list\""
After devices/object founded, we need to access or use them.
for this case we have tried many interface such as block-device, system-files, … etc. But we fail to let them work.
So anyone can help us?
Thanks!
