i just used the tune2fs command to recover space on my secondary drive.
Afterwards i unmounted the drive and ran a e2fsck -f <device>. No error
was reported. Actually i used the tune2fs when the device was mounted so
i just became paranoid. now the e2fsck reported no error does that mean
my filesystem is still intact and no potential harm has been done ?
when i remount the drive and run df -h i see an extra 6G of free space.
does e2fsck also check for data corruption or data integrity ?
William, can you please tell in details if more space can be recovered
by using your two options and lastly is tweaking the default options of
file system a good thing or bad thing ?
