Over 2T, disk partitioning

MBR:MBR partition table (that is, master boot record) Everyone is familiar with it. Maximum supported volumes: 2T, with restrictions on partitions: up to 4 primary partitions or 3 primary partitions plus one extended partition

Gpt:gpt (that is, the GUID partition table). Is the standard of a newer disk partitioning table structure originating from the EFI standard, which is the primary form of future disk partitioning. Compared with MBR partitioning method, it has the following advantages. The MBR 4 primary partition limit is exceeded, with a maximum of 128 partitions per disk. Supports partitions larger than 2T, with a maximum volume of up to 18EB.

-. Using parted

No parted command.

# yum-y Install parted

1, the DEV/SDB partition

Parted/dev/sdb

2. Set the type of partition

(parted) Mklabel GPT

3. Print partition information

(parted) p

4. Partitioning

0TB

0.00B to0TB.                   17.4kB to0TB. Is this still acceptable? Yes/no? Yes (enter Yes)                                                             for Best performance. Ignore/cancel? I (Input i)

5. View partition partition information and exit

/dev/sdb:40. 0TB Sector Size (logical/physical): 512b/4096B Partition table:gpt number  Start    End     Size    File system  Name     Flags   1      17.4kB  40.0TB  40.0TB               Primary

(parted) quit

Second, XFS format large partition

# Yum install kmod-xfs xfsprogs # modprobe XFS       //Loading XFS file system module #lsmod |grep xfs    //See if XFS modules are loaded

Format and Mount with XFS

# mkfs.xfs-f/dev/sdb1 # Mount/dev/sdb1/data

Set system boot Auto mount partition

# cat  /etc/fstab     /dev/sdb1  /data xfs  defaults  0  0

View the status of all disks

# parted-l
