ext3文件系统大于8T

ext3文件系统大于8T
有台存储有12T的磁盘，需要使用gpt分区，并且格式化的时候需要加“-F”，具体如下：
[Copy to clipboard]View Code TEXTparted /dev/sdb

(parted) print
Error: Unable to open /dev/sdb - unrecognised disk label. //这里无需理会

(parted) mklabel
New disk label type? gpt
(parted) print
Model: Promise 14 Disk RAID5 (scsi)
Disk /dev/sdb: 12.9TB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

Number Start End Size File system Name Flags

(parted) mkpart primary 0 12.9TB
(parted) print

Model: Promise 14 Disk RAID5 (scsi)
Disk /dev/sdb: 12.9TB

Partition Table: gpt

Number Start End SizeFile system Name Flags
1 17.4kB 12.9TB 12.9TB primary

(parted) quit

格式化：

mkfs.ext3 -F /dev/sdb1 //需要加“-F”选项才行，不然会出现。

mkfs.ext3: Filesystem too large. No more than 2**31-1 blocks
(8TB using a blocksize of 4k) are currently supported.
大于8T的分区block至少要大于4k，4k能支持最大为16T的磁盘。
