HD is IDE HDD SDA is SCSI hard disk
For example , Sda2: Represents the first 2 partitions of a SCSI hard disk ;
4 partitions ( primary and extended partitions ) 1-4 start
the logical partition starts at 5 . First Partition sda1 SDA, omit 1
SDB2 represents the first 2 Primary or extended partition of the 2 SCSI hard disk
Sdc6 represents the first 2 logical Partitions of the 3 SCSI disks
Requirements to install dual systems for Windows and linux :
system is Windows . to install linux system must vacate the unallocated partition to completely remove this partition then restart the system boot system booting with CD or other media
The Installation interface , if in boot back input linux text Span style= "font-family: ' The song Body '; > install install without entering any characters on the graphical interface.
3. If there is a problem with the installed system , you can boot up and then press F5 to repair the system . and then in Boot after input Linux Rescue.
hard disk partition :
1. It is recommended to select Manual partitioning manual partion with disk Gurid
2. a warning appears and the direct Yes skips .
3. Zoning Instructions
3-1./ partition /swap swap partition
3-2. Swappartitions are equivalent toLinuxthe virtual memory,Recommended Settings.size is generally physical memory.2Times.such as less than4Gof the,is set to4G.Greater than4Gless than16Gset the physical memory size.if greater than16Gyou can set it to0,but this is not recommended..SetSwaphas some effect on the size of the.
in general Linux Systems , the system can be installed by dividing the root partition and the swap partition . but for security . . Separate partitions are generally divided into separate data , This system is damaged , data doesn't have to worry about losing. .
/boot storage System boot file and kernel information
/usr storage System application software installation information
/var storage System Log Information
These partitions are best partitioned separately . Otherwise it will occupy / Boot of Space . data is not secure .
It is recommended that the root partition be larger , or the system will stop responding if the space is full .
root partition select / size is generally 5GB;
another Boot partition /boot don't need too much There are generally 100MB enough to use the files such as the storage System boot file and the kernel use the The file system is also EXT3;
then create the/swap partition , swap the partition . File System Selection Swap type . Swap does not require a mount point . so it's gray. , cannot choose .
then divide /usr /var step basically the same as , is the size of the different If you have more applications installed usr partition larger partition of a larger number of
if you have more space left after the partition has ended, you can create your own data partition separately . Example :/mydata Partitioning , to store your own data. . each partition is preceded by a / , because all partitions are started under the root partition. .
It is best to use the last partition to fully allocate the remaining space of the system .
mount point Customization is best consistent with the name of the partition . File System Selection ext3; then choose the maximum amount of disk size to use , so we can use all the rest of the system. .
The partition interface can choose to edit , delete , and reset the partition .
Create A raid array : A separate redundant disk array . typically for large server data storage and redundancy issues .
