Package: zram-tools
Version: 0.3.3.1-1
Severity: important
Zram does not start when I launch my computer :
root@PC:~# systemctl status zramswap.service
[zramswap[4580]: /usr/sbin/zramswap: ligne 53 : echo: erreur d'écriture :
Périphérique ou ressource occupé]
It refers to lign 53 which is :
echo -n "${ALGO}" > /sys/block/zram0/comp_algorithm || elog "setting
compression algo to ${ALGO}"
When I try to write in this file, it fails :
root@PC:~# echo -n "lz4" > /sys/block/zram0/comp_algorithm
-bash: echo: erreur d'écriture : Périphérique ou ressource occupé
root@PC:~# ls -al /sys/block/zram0/comp_algorithm
-rw-r--r-- 1 root root 4096 5 mai 20:09 /sys/block/zram0/comp_algorithm
root@PC:~# ls -al /sys/devices/virtual/block/zram0/comp_algorithm
-rw-r--r-- 1 root root 4096 5 mai 20:09
/sys/devices/virtual/block/zram0/comp_algorithm
root@PC:~# echo $UID
0
root@PC:~# mount
[sysfs on /sys type sysfs (rw,nosuid,nodev,noexec,relatime)]
I can't modify or delete this particular file, and Zram can't start without
modifying it.
Sorry for the french in the messages and for the quality of my report, it's
only my second.
