iam confused about setting Resources in postgres unit file. I setup the following files:
cat /etc/systemd/system/postgresql.service.d/50-BlockIOWeight.conf
[Service]
BlockIOWeight=10
cat /etc/systemd/system/postgresql.service.d/50-CPUShares.conf
[Service]
CPUShares=10
then i make:
systemctl daemon-reload
systemctl restart postgresql.service
now i thought i can get the actual values of the service via:
systemctl show postgres.service | grep CPUShares
CPUShares=18446744073709551615
StartupCPUShares=18446744073709551615
Also the following gets nothing:
cat /sys/fs/cgroup/blkio/system.slice/postgresql.service/blkio.weight
cat: /sys/fs/cgroup/blkio/system.slice/postgresql.service/blkio.weight: Datei oder Verzeichnis nicht gefunden
But if i delete my configurations and restart service and then set property instant, i can cat the configuration in /sys/fs/ .... see here:
rm -rf /etc/systemd/system/postgresql.service.d/50-*
systemctl daemon-reload
systemctl restart postgresql.service
cat /sys/fs/cgroup/cpu,cpuacct/system.slice/postgresql.service/cpu.shares
cat: /sys/fs/cgroup/cpu,cpuacct/system.slice/postgresql.service/cpu.shares: Datei oder Verzeichnis nicht gefunden
systemctl set-property postgresql.service CPUShares=10 BlockIOWeight=10
cat /sys/fs/cgroup/cpu,cpuacct/system.slice/postgresql.service/cpu.shares
10
but systemd show shows still no cpushares value:
systemctl show postgres.service | grep CPUShares
CPUShares=18446744073709551615
StartupCPUShares=18446744073709551615
also the files in /etc/systemd was created
ls -la /etc/systemd/system/postgresql.service.d/
insgesamt 16
drwxr-xr-x 2 root root 4096 Jul 4 08:28 .
drwxr-xr-x 19 root root 4096 Jul 3 11:47 ..
-rw-r--r-- 1 root root 27 Jul 4 08:28 50-BlockIOWeight.conf
-rw-r--r-- 1 root root 23 Jul 4 08:28 50-CPUShares.conf
so setting via set-property with running service works ? but after simple restart the service all is gone, although the configurations are still present in /etc/systemd/system/postgresql.service.d/
Whats wrong here ?
