"Next all pass 2 partitions are checked in parallel, one process per disk drive." so having 5 partitions on one SSD - it will be checked sequentially. > Also note that "one process per disk" refers to old traditional partition numbering > like da0s1a, da0s1d, da0s1e that fsck recognises as belonging to same "disk" > but not to newer label-based mount like /dev/ufs/root, /dev/ufs/var or /dev/mirror/m0s1a etc. > so it runs it all in parallel unless you deny it using different pass numbers. > i use /dev/gpt/gptlabel naming. so it will check in parallel.
