1. File Type IntroductionExt4 Extended File system features support for single file on EB support log function NTFS files and FAT32 do not support 4G on a single fileSwap swap partition virtual memory 8G 8G 4G 1.5 times times MBR partition Table mode: Support 4 primary partitions do not recognize a single hard drive more than 2TB
GPT Partitioning mode multiple primary partitions support more than 2T hard drives
we use the MBR partition, set up two primary partitions, establish multiple logical partitions in the second primary partition, i.e. Windows c,d,e,f disk, etc.
Linux establishes a primary partition, an extended partition, that is, SDB1 and sdb2 in the SDB2 to establish a logical partition, (only the primary partition in Linux can use the drive letter is SDB1-SDB4), so the first block of the logical partition can only be SDB5, followed by the subsequent deferred.
2. Zoning requirements: Three zones 1 primary partitions two logical partitions each partition size is 500M, SDA1 established as Ext4 file system
ADA5 set up FAT32 file system ADA6 Create swap partition
