.SH MODES
mdadm has several major modes of operation:
.TP
.B Create
Create a new array with per-device superblocks.
-'''It can progress
-'''in several step create-add-add-run or it can all happen with one command.
+.\"It can progress
+.\"in several step create-add-add-run or it can all happen with one command.
.TP
.B "Follow or Monitor"
This is an 'everything else' mode that supports operations on active
arrays, operations on component devices such as erasing old superblocks, and
information gathering operations.
-'''This mode allows operations on independent devices such as examine MD
-'''superblocks, erasing old superblocks and stopping active arrays.
