Looking to confirm true nature of behaviour.
I use an External USB drive for backups.
Using tune2fs, I have specified a mountcount value of 20 for each of the partitions on that drive. I can't remember how, but I did specify the individual count on each partition so that the fsck would be staggered (not all at the same boot) if I always mount all those USB partitions every time.
QUESTION:
If the partition's "mountcount" dictates that this power-up event would reach the count at which an fsck should be performed,
-
with no auto-mount directive in place, does the simple act of plugging in the USB drive trigger the fsck action ... before any mount directive has been given? or
-
does the OS perform the fsck only as a pre-requisite first step during the performance of the mount command?
