楼上兄弟回复的都非常全,要看支持的文件系统最大大小,可以man crfs命令里面有介绍,
Specifies the size of an Enhanced Journaled File System (JFS2). Size can be specified in units of 512-byte
blocks, Megabytes or Gigabytes. If Value has the M suffix, it is interpreted to be in Megabytes. If Value has a
G suffix, it is interpreted to be in Gigabytes. If the specified size is not evenly divisible by the physical
partition size, it is rounded up to the closest number that is evenly divisible. This attribute is required
when creating a JFS2 file system unless the -d flag has been specified. If the -d flag is specified, the file
system is the size of the logical volume. The volume group in which the file system resides defines a maximum
logical volume size and limits the file system size. The minimum size for a JFS2 file system is 16 MB. The
maximum size is determined by the file system block size:
fs block size (byte) MAX fssize (TB)
