            Bug ID: 194511
           Summary: filesystem slow down
           Product: File System
           Version: 2.5
    Kernel Version: 4.4.44 und 4.8.???
          Hardware: All
                OS: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: ext3
          Assignee: fs_ext3@kernel-bugs.osdl.org
          Reporter: dieter.ferdinand@gmx.de
        Regression: No

hello,
last month i try to update to the last kernel 4.4.xx. but that was a big fault.

after the update, it looks fine, but after some time (ca 30 minutes after a
restart of the server, the system slow down and i need to much time to copy
files to the drives.

i test the speed:
read usb >30000 MB/s
read sata >100000MB/s
write filesystem usb ca 1 MB/s
write filesystem sata ca 1 MB/s

this month i used a rescue-system with a kernel 4.8.??? to change a
harddisk-config on a server and i get the same problem:
to backup, format and restore a filesystem with less then 1 GB data i need over
2 hours.
the initialisation of a 160GB ext3-filesystem need over 30 minutes. this is
impossible!

at the same time, a raid is rebuild with over 100 MB/s. i stop the rebuild, but
this have no effect to the write-speed of mke2fs to init the filesystem. at
last, i reinstall the system in less then 30 minutes two times again because
the system don't boot after my changes. i think a selinux-problem.
this systenm use kernel 3.10.0 at the moment without problems.

after two days, i install the kernel 3.18.47 from kernel.org to have the latest
3.xx kernel and this kernel works fine and since installation without problems.

only, i must deaktivate initramfs, but i think, that is no problem of the
kernel and i have no time to analyse this problem at the moment.

goodby

--- Comment #1 from Theodore Tso <tytso@mit.edu> ---
I am currently running with a 4.9 kernel (and previously I was using a 4.8
kernel, and before that I was using 4.4) on my development laptop and I
certainly wasn't seeing the sort of performance numbers you are seeing.

Nor has anyone else been complaining about this --- and given that there are a
lot of people running Debian testing with a 4.8 kernel, I'm sure we would have
heard the complaints if this was a widespread problem.

So there must be something fairly unique about either your hardware or software
configuration.   Or perhaps your kernel configuration.   We would need all of
that information in order to be able to even start looking at your complaint.

kernel configuration

hello,
i can send you only my configuration of the kernel at the moment and some infos
about my hardware because i can't restart the other server at the moment.

i have a big problem with such bugs: they will find me all and this is not the
first time, that i have a bug which don't have any other user.
sample: bug in capi-driver which used by asterisk. much time later the
programms warn to use this driver. the time i send informartion of this bug i
get only as response, that all works fine.

i try to send you all information of the other system, next time i start it.
but i don't know which kernel the system use at this time because i send the
provider a mail to change to the last 3.xxx kernel to solve the problem.
