Hi,
when I as root do "touch /forcefsck" and reboot, then fsck will be done.
But afterwards one has less free memory available than normal.
Example:
used mem immediately after login:
without fsck during boot: 98 MB (this the normal level here)
with fsck during boot : 139 MB
So, there is a memory leak of about 41 MB.
This discrepancy is reproducible here, ie. happens always.
Not sure, but it could also be a kernel issue, because
the longer the system runs the more memory gets bound.
The source of the culprit is not easily detectable.
I guess it gets eaten by the kernel, probably by the ext4-driver.
fsck from util-linux 2.25.2
Filesys: ext4, 500 MB SSD
fix: of course 500 GB was meant
OS: Debian 8 X86_64, uptodate
And are you talking about fsck (wrapper) or fsck.ext4 (from
e2fsprogs)?
I don't know which one gets used in the above scenario because
it is done automatically by the system.
But the problem is solved now by setting /proc/sys/vm/drop_caches
to the value 3 as was written in the other postings.
