Changing lvmcache mode
by Raman Gupta
I would like to change the cache mode of an existing lvm cache volume.
I see the following in the man page:
`With the --cachemode option, the cache mode can be set when creating
a cache LV, or changed on an existing cache LV.`
However, it does not seem to work:
# lvs -o cache_mode vg_raid10/lv_var
CacheMode
writethrough
# lvconvert --cachemode writeback vg_raid10/lv_var
# lvs -o cache_mode vg_raid10/lv_var
CacheMode
writethrough
(Fedora 23, 4.8.14)
The `lvconvert` command produces no output, and there is nothing in
dmesg or the journal.

Raman

Hibernation locks the system instead of hibernating
by Sudhir Khanger
Hi,
I am setting up a new Dell Precision 5510. It has 16gb of RAM. I chose to create a swapfile of 24gb (1.5 times is recommended by RHEL 7 docs).
The swap is on, resume flag has been set in /etc/default/grub, and secure boot if off. That's my understanding of the common bug entry.
When I hibernate my system it simply locks the system. No hibernation is done. I gave Kubuntu a try to see if there is a problem with hibernation and it works fine on Kubuntu.
If you guys have any ideas I would really appreciate it.
Regards,

closing lid of laptop
by Paolo Galtieri
I have a question regarding what is supposed to happen when I close the
lid of a laptop. I always assumed that closing the lid would cause the
system to go into suspend mode and wake up when the lid was opened.
What I mean by suspend is that the system should be doing very little so
as to not consume battery. However, what I have observed with my laptop
when I upgraded to F25 is that the system is still active. I have an
ssh session into the laptop from another system and this session is
still active after I close the lid. So the question is what is supposed
to happen when I close my laptop's lid?
Any help is appreciated.
Thanks,
Paolo

DVD
by Patrick Dupre
Hello,
I cannot rad DVD on my laptop;*
Here are the sort of mesages that get:
Gnome MPlayer Error: couldn't open DVD device: /dev/dvd (No suchfile or directory)
DVD subpicture decoder, DVD subpicture decoder are required to play the file, but are not installed
FAILED - Could not access dvdcdrom: /dev/dvd
gxine:
Either create a symbolic link /dev/dvd pointing to your cdrom device or set cdrom device in the preferences dialog
If you are using the ise-cd module ensure that you have the following entry in /etc/modules:
options ide-cd dma=1
Reload ide-cd module.
Otherwise run hdparm -d 1 on your dvd-device
/dev/sr0 on /run/media/pdupre/ROUBLEV type udf (ro,nosuid,nodev,relatime,uid=1000,gid=1000,iocharset=utf8,uhelper=udisks2)
The only thing that I can do is to view the file:
/run/media/pdupre/ROUBLEV/VIDEO_TS/VIDEO_TS.VOB
WHich shouldme access to the rest of the DVD, but then I get an error message:
cannot find .......
Any idea?
Thank.
