19# Usage:
20#   mmdeldisk Device {"DiskDesc[;DiskDesc]" | -F DescFile} [-a] [-c] [-p]
21#             [-r] [-N {all | mount | Node[,Node...] | NodeFile | NodeClass}]
22#
23# where
24#   Device    is the file system device name
25#
26#   DiskDesc  is a descriptor of a disk to be deleted.  Only the disk name
27#             part of the descriptor is significant.  If more than one disk
28#             is to be deleted, the list of disk names (descriptors) must
29#             be ";" separated and enclosed in double quotes.
30#
31#   -F DescFile  is a file containing disk descriptors, one per line.
32#
33#   -p        indicates that the disk(s) are permanently damaged.
34#             All references will be deleted without data migration.
35#
36#   -c        ignore IO errors while migrating data off the deleted disks
37#
38#   -r        rebalance stripe group when done
39#
40#   -a        do not wait for rebalancing to finish
41#
42#   -N        parallel restripe options:
43#               all      - use all of the nodes in the nodeset
44#               mount    - use only the nodes that have mounted the fs
45#               nodelist - use only the specified nodes
