Re: [Kernel-packages] [Bug 1838276] Re: zfs-module depedency selects random kernel package to install

2019-07-31 Thread Hajo Möller
Would turning the hard dependency into a somewhat softer recommendation be
a possible solution?

Do zfsutils require the module to be actually installed, or would rw access
to /dev/zfs suffice?

Hajo Möller

Zero-filled data is not compressed by the set compression algorithm but
gets filtered by zero-length encoding, so the zeros never hit lz4 and
compressratio does not include them.

  I have a zfs filesystem containing a single qemu kvm disk image. The

Re: [Kernel-packages] [Bug 1639963] [NEW] zfs get compressratio returns bogus results

2016-11-07 Thread Hajo Möller
ZFS works as intended, here. Zero-filled blocks are not counted into the
compression ratio, as they get dismissed early in the compression
pipeline and never hit the disks as used data:

# zfs create sbblht/test

# dd if=/dev/zero of=/test/a bs=16M count=8
8+0 records in

  I noticed that zfs get compressratio was not returning good results,
  and tested to ensure it was the compressratio reporting that was
  broken, not the actual compression.  Demonstration:

  root@xenial:~# zfs get compress data/test
  NAME   PROPERTY VALUE SOURCE
  data/test  compression  gzip  local
  root@xenial:~# zfs list data/test
  NAMEUSED  AVAIL  REFER  MOUNTPOINT
  data/test  2.64G   855G  2.64G  /data/test

  Note that data/test has inline gzip compression on, and shows 2.64G of
  data USED.

  root@xenial:~# du -hs --apparent-size /data/test
  9.2G  /data/test
  root@xenial:~# du -hs /data/test
  2.7G  /data/test

  Now note that du correctly shows us that we have 9.2G of data stored
  in data/test (about 7G of which is actually a dump from /bin/zero for
  max compressibility, the other bit being an Ubuntu VM image file).

  We should be seeing a compressratio of about 3.41x.

  root@xenial:~# zfs get compressratio data/test
  NAME   PROPERTY   VALUE  SOURCE
  data/test  compressratio  1.01x  -

  But we're seeing 1.01x.  Obviously very much not correct.

Colin, thank you for the fix, I will switch to xenial-proposed now.

As a followup, upstream merged my PR so 1014-kernel-lookup-bdev.patch
may be removed once the next ZFS on Linux release gets synced to us,
hopefully in time for zesty.

  [Regression Potential]

  Minimal. This just touched one line in the zfs module
  module/zfs/zvol.cand a shim wrapper in include/linux/blkdev_compat.h

  Tested and passes with the ubuntu kernel team autotest client zfs
  regression tests.

  =

  I traced this back to 193fb6a2c94fab8eb8ce70a5da4d21c7d4023bee (erged
  in 4.4.0-6.21), which added a second parameter to lookup_bdev without
  patching the zfs module (which needs to special case the vdev-on-zvol
  case, and uses this exact method only in this special casing code
  path).

  attached you can find the output of "zfs send -R" ing such a zvol
  ("brokenvol.raw"), running "zfs receive POOL/TARGET < FILE" followed
  by "zpool import" should reproduce the hang.

  I traced this back to 193fb6a2c94fab8eb8ce70a5da4d21c7d4023bee (merged
  in 4.4.0-6.21), which added a second parameter to lookup_bdev without
  patching the zfs module (which needs to special case the vdev-on-zvol
  case, and uses this exact method only in this special casing code
  path).

  attached you can find the output of "zfs send -R" ing such a zvol
  ("brokenvol.raw"), running "zfs receive POOL/TARGET < FILE" followed
  by "zpool import" should reproduce the hang.

[Kernel-packages] [Bug 1597895] Re: i915 crashes, lightdm unresponsive and VT switching impossible

2016-07-04 Thread Hajo Möller
If I remember correctly the issue appeared shortly before 16.04 was
released, but I may have overlooked it before.

I will test the latest upstream kernel once I find time to create a
fresh installation on some other media, this system boots off ZFS and
thus doesn't work with 4.7 as of now.

Title:
  i915 crashes, lightdm unresponsive and VT switching impossible

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Some times after locking the screen and waking it up some time later
  via Fn (XF86WakeUp) lightdm accepts no input and Ctrl+Alt+Fx no longer
  work to switch to another VT.

  This is not always reproducible but I think it's triggered by clicking
  on lightdm's login dialog before it's ready.

  What usually happens when I wake up the screen:
  - the screen shows the lightdm dialog without a blinking cursor for a second
  - screen turns black (off?) for a second, as if its resolution changes
  - screen comes back, shows lightdm dialog, cursor begins to blink

  I will try to reproduce by clicking on the dialog before the screen
  goes black soon.

  This may be related to https://bugs.launchpad.net/ubuntu/+source
  /xserver-xorg-video-intel/+bug/1568604 - which affects my
  installation, too.

  Here's the relevant snippet from /var/log/syslog, I pressed the power
  button a few seconds after realizing the lock up:
