2.4.1 align-check

Command: align-check align-type n

Determine whether the starting sector of partition n meets the disk’s selected alignment criteria. align-type must be ‘minimal’, ‘optimal’ or an abbreviation. When in script mode, if the partition does not meet the alignment requirement, exit with status 1; otherwise (including on older kernels for which alignment data is not available), continue processing any remaining commands. Without --script, print either ‘N aligned’ or ‘N not aligned’.

Example:

(parted) align-check minimal 1
1 aligned
