Public bug reported:
Hi,
While testing how zram-config is going in Ubuntu Vivid, I meet with
error while doing restart and or stop/start.
It seems to stop fine but throws an error when starting again or
performing a restart.
I have installed zram-config 0.3 just today and haven't rebooted yet.
The CPU is "AMD Athlon(tm) II X2 260 Processor"
As stated in bug #1449665 there is one block device created:
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/zram0 partition 947216 0 5
$
Here:
$ sudo systemctl stop zram-config
$ cat /proc/swaps
Filename Type Size Used Priority
/dev/zram0 partition 947216 0 5
$
after the stop, the prompt is back without error, but it has done
nothing.
With restart:
$ sudo systemctl restart zram-config
Job for zram-config.service failed. See "systemctl status zram-config.service"
and "journalctl -xe" for details.
$
When invoking the suggested commands:
****
$ LANG=C systemctl status zram-config.service -l

I have done a test using directly the scripts created for /usr/bin, the
results seem interesting:
$ sudo /usr/bin/end-zram-swapping
rmmod: ERROR: unexpected getopt_long() value 'w'.
$ cat /proc/swaps
Filename Type Size Used Priority
$
$ LANG=C sudo /usr/bin/init-zram-swapping
sh: echo: I/O error
mkswap: error: /dev/zram0 is mounted; will not make swapspace
swapon: /dev/zram0: swapon failed: Device or resource busy
/usr/bin/init-zram-swapping: 21: /usr/bin/init-zram-swapping: cannot create
/sys/block/zram1/disksize: Directory nonexistent
/dev/zram1: No such file or directory
swapon: stat failed /dev/zram1: No such file or directory
$
I hope I have tested the right way. If anything more is needed, log
files or so, please ask.
Best regards,
Mélodie
