    Description

      The Lustre manual states for ‘lfs mirror extend’ 

      The mirror_count argument is optional and defaults to 1 if it is not specified; …

      In Lustre 2.12.3 and master, the mirror-count option is required

      # cp test-framework.sh /mnt/lustre/.
# lfs getstripe /mnt/lustre/test-framework.sh
/mnt/lustre/test-framework.sh
lmm_stripe_count:  1
lmm_stripe_size:   1048576
lmm_pattern:       raid0
lmm_layout_gen:    0
lmm_stripe_offset: 1
    obdidx         objid         objid         group
         1                 3              0x3                 0

# lfs mirror extend -c -1  /mnt/lustre/test-framework.sh
error: lfs mirror extend: --mirror-count|-N option is required

      We should make ‘lfs mirror’ easier to use and use a default value for the mirror count is one is not provided on the command-line.
