第10题:

An administrator is trying to extend an existing volume group with a new hard disk, but the extendvg command returns the following error. 0516-1162 /usr/sbin/extendvg. Warning, The Physical Partition Size of 64 requires the creation of 8924 partitions for hdisk11. The limitation for volume group datavg is 1016 physical partitions per physical volume. Use chvg command with -t option to attempt to change the maximum Physical Partitions per Physical volume for this volume group. The chvg -t may or may not allow the extendvg command to succeed. What is the implication of using this option?()

  • A、It reduces the maximum file size allowed within the given volume group.
  • B、It reduces the maximum number of files allowed within the given volume group.
  • C、It reduces the maximum number of logical volumes allowed within the given volume group.
  • D、It reduces the maximum number of physical volumes allowed within the given volume group.

正确答案:D
