Question #34
A N8500 (V200R001) clustered NAS system with a set of storage units at the back end. Three RAID Groups, respectively named RG1, RG2, RG3 have been created on the storage unit. There are two LUNs under each RAID group, the capacity of each LUN is 12G.
The names are RG1-LUN1, RG1-LUN2, RG2-LUN1, RG2-LUN2, RG3-LUN1, RG3-LUN2, and all LUNs are added to one in storage pool. The purpose is to create a file system based on these LUNs. What of the following will certainly create a failure?
  1. A
    fs create striped fs01 10g 3 RG1-LUN1, RG2-LUN1, RG3-LUN1 stripeunit = 2048 blksize = 8192
  2. B
    fs create mirrored fs02 10g 2 RG1-LUN2, RG2-LUN2 stripeunit = 2048 blksize = 8192
  3. C
    fs create mirrored-stripe fs03 10g 2 2 RG1-LUn1, RG2-LUN1 protection = disk stripeunit = 2048 blksize = 8192
  4. D
    fs create striped-miiro fs04 20g 2 3 RG1-LUn1, RG1-LUN2, RG2-LUN1, RG2-LUN2, RG3-LUN1, RG3-LUN2 protection = disk stripeunit = 512 blksize = 1024

Correct Answer:
C
