[root@localhost sysadmin]# fdisk -l WARNING: GPT (GUID Partition Table) detected on '/dev/sda'! The util fdisk doesn't support GPT. Use GNU Parted. Disk /dev/sda: 40000.0 GB, 39999997214720 bytes 255 heads, 63 sectors/track, 4863055 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sda1 1 267350 2147483647+ ee GPT
說明：此時文件系統己經超過16T，OS默認將其轉換成了GPT格式的，所以使用fdisk無法查看到准確的分區信息。 二、使用parted 查看分區信息
[root@localhost sysadmin]# parted GNU Parted 2.1 Using /dev/sda Welcome to GNU Parted! Type 'help' to view a list of commands. (parted) p Model: LSI AOC-USAS2LP-H8iR (scsi) Disk /dev/sda: 40.0TB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 525MB 524MB ext4 2 525MB 263GB 262GB ext4 3 263GB 284GB 21.0GB ext4 4 284GB 288GB 4295MB linux-swap(v1)
三、將余下的空間都分為/archive 作為歸檔的根目錄
(parted) mkpart /archive 288G -1 (parted) p Model: LSI AOC-USAS2LP-H8iR (scsi) Disk /dev/sda: 40.0TB Sector size (logical/physical): 512B/512B Partition Table: gpt Number Start End Size File system Name Flags 1 1049kB 525MB 524MB ext4 2 525MB 263GB 262GB ext4 3 263GB 284GB 21.0GB ext4 4 284GB 288GB 4295MB linux-swap(v1) 5 288GB 40.0TB 39.7TB /archive (parted)q
四、查看分區 [root@localhost ~]# fdisk /dev/sda sda sda1 sda2 sda3 sda4 sda5 [root@localhost ~]# 說明：此時己經找到新的分區【sda5】 五、修改/etc/mke2fd.conf
#vim /etc/mke2fs.conf
[fs_types]
ext3 = {
features = has_journal
}
ext4 = {
features = has_journal,extent,huge_file,flex_bg,uninit_bg,dir_nlink,extra_isize
auto_64-bit_support = 1 #添加這一行
inode_size = 256
}
六、下載e2fsprogs-1.42.13.tar.gz
[root@localhost ~]# wget -c http://jaist.dl.sourceforge.net/project/e2fsprogs/e2fsprogs/v1.42.8/e2fsprogs-1.42.13.tar.gz [root@localhost e2fsprogs-1.42.13]# pwd /home/sysadmin/e2fsprogs-1.42.13 [root@localhost e2fsprogs-1.42.13]# cd build/ [root@localhost build]# ../configure .... [root@localhost build]# make && make install
七、格式化分區
[root@localhost ~]# mke2fs -O 64bit,has_journal,extents,huge_file,flex_bg,uninit_bg,dir_nlink,extra_isize -i 2048 /dev/sda5 [root@localhost build]# blkid /dev/sda1: UUID="908a3c8e-6d6a-4e01-8cad-2094ea99751f" TYPE="ext4" /dev/sda3: UUID="b533714f-4cb9-4394-907d-8d1ead424c85" TYPE="ext4" /dev/sda2: UUID="0a0ec20e-b50b-4d89-9fa6-65602e4e8a3d" TYPE="ext4" /dev/sda4: TYPE="swap" UUID="b8e89719-670f-4b26-bbf3-86d13a1f935e" /dev/sda5: UUID="3b5789ee-94c2-4296-bd99-5669200d826a" TYPE="ext4"
注： mke2fs格式說明： -b<區塊大小>：指定區塊大小，單位為字節； -c；檢查是否有損壞的區塊； -f<不連續區段大小>：指定不連續區段的大小，單位為字節； -F：不管指定的設備為何，強制執行mke2fs； -i<字節>：指定"字節/inode"的比例； -N：指定要建立的inode數目； -l<文件>：從指定的文件中，讀取文件西中損壞區塊的信息； -L<標簽>：設置文件系統的標簽名稱； -m<百分比值>：指定給管理員保留區塊的比例，預設為5%； -M：記錄最後一次掛入的目錄； -q：執行時不顯示任何信息； -r：指定要建立的ext2文件系統版本； -R=<區塊數>：設置磁盤陣列參數； -S：僅寫入superblock與group descriptors，而不更改inode able inode bitmap以及block bitmap； -v：執行時顯示詳細信息； -V：顯示版本信息。 八、將對應的分區掛載即可以使用
[root@localhost build]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda3 20G 2.4G 16G 14% / tmpfs 7.8G 0 7.8G 0% /dev/shm /dev/sda1 477M 80M 372M 18% /boot /dev/sda2 241G 120M 228G 1% /home /dev/sda5 36T 20K 34T 1% /archive [root@localhost build]# df -i Filesystem Inodes IUsed IFree IUse% Mounted on /dev/sda3 1281120 91214 1189906 8% / tmpfs 2040386 1 2040385 1% /dev/shm /dev/sda1 128016 46 127970 1% /boot /dev/sda2 16007168 1955 16005213 1% /home /dev/sda5 4293781536 11 4293781525 1% /archive
九、查看磁盤信息
[root@localhost build]# tune2fs -l /dev/sda5 tune2fs 1.42.13 (17-May-2015) Filesystem volume name: <none> Last mounted on: <not available> Filesystem UUID: 3b5789ee-94c2-4296-bd99-5669200d826a Filesystem magic number: 0xEF53 Filesystem revision #: 1 (dynamic) Filesystem features: has_journal ext_attr dir_index filetype needs_recovery extent 64bit flex_bg sparse_super huge_file uninit_bg dir_nlink extra_isize Filesystem flags: signed_directory_hash Default mount options: user_xattr acl Filesystem state: clean Errors behavior: Continue Filesystem OS type: Linux Inode count: 4293781536 Block count: 9695327232 Reserved block count: 484766361 Free blocks: 9426221107 Free inodes: 4293781525 First block: 0 Block size: 4096 Fragment size: 4096 Group descriptor size: 64 Blocks per group: 32768 Fragments per group: 32768 Inodes per group: 14512 Inode blocks per group: 907 Flex block group size: 16 Filesystem created: Thu Oct 15 15:27:56 2015 Last mount time: Thu Oct 15 15:33:50 2015 Last write time: Thu Oct 15 15:33:50 2015 Mount count: 1 Maximum mount count: 33 Last checked: Thu Oct 15 15:27:56 2015 Check interval: 15552000 (6 months) Next check after: Tue Apr 12 15:27:56 2016 Lifetime writes: 202 MB Reserved blocks uid: 0 (user root) Reserved blocks gid: 0 (group root) First inode: 11 Inode size: 256 Required extra isize: 28 Desired extra isize: 28 Journal inode: 8 Default directory hash: half_md4 Directory Hash Seed: 56a5949a-5a49-4bc9-810d-9a9e2aa2109b Journal backup: inode blocks
