e2fsck: checking number of days since last backup

CHIhost-Corey · 11-24-2012, 12:48 PM

Hello, I'm looking for a way to determine the number of days since a drive was last scanned with e2fsck. I'm assuming it keeps a variable somewhere and tracks the days there (since it outputs the number of days since the last check when you run a scan), but does anyone know where that variable can be accessed? Thanks in advance!

Have a look at the output of:

Code:

dumpe2fs -h /dev/xyz

This is part of the output (one of my partitions):

$ dumpe2fs -h /dev/sda2
