问题描述: Problem Description:
在一个预先定义好的逻辑卷上创建一个文件系统，系统产生错误信息：0516-404: The system can't fulfil the allocation request. There are not enough free PPs or not enough PVs to keep strictness. In a pre-defined logical volume to create a file system, the system generates an error message :0516-404: The system can't fulfil the allocation request. There are not enough free PPs or not enough PVs to keep strictness.
解答: Answer:
上述问题的产生是由于在创建预定义的逻辑卷时使用完了对应卷组中所有的剩余空间，所以当在上面再创建文件系统时，就没有剩余的空间用来分配给jfs log （文件系统日志）了。 These problems arise is due to pre-defined logical volume is created using the corresponding volume group finished all the remaining space, so when in the above re-create the file system, there is no remaining space to be allocated to jfs log (the file system log ) of the. 系统缺省的jfs log（文件系统日志）大小为一个PP（物理分区），一般每2GB的文件系统需要4MB空间的jfs log（文件系统日志），jfs log（文件系统日志）最大为256MB。 The system default jfs log (the file system log) the size of a PP (physical partition), for every 2GB generally require 4MB of file system space jfs log (the file system logs), jfs log (the file system logs) a maximum of 256MB. 因此，当发生上述的错误时，需要删除掉已经预先定义好的逻辑卷，再根据要创建的文件系统的大小估算出需要的jfs log（文件系统日志）的大小，在卷组中留出足够的用于产生jfs log（文件系统日志）的剩余空间，之后再创建逻辑卷，并在上面创建需要的文件系统。 Thus, when the occurrence of the above errors, you need to delete pre-defined logical volume, and then create a file system according to the size of the estimated needs of jfs log (the file system log) the size of the volume group set aside sufficient used to generate the jfs log (the file system logs) and the remaining space, after creating logical volumes, and create the documents required in the above system.
