Public bug reported:
Currently pacemaker v2 fails to start in armhf containers (and by
extension corosync too).
I found that it is reproducible locally, and that I had to bump a few
limits to get it going.
Specifically I did:
1) bump memlock limits
2) bump rmem_max limits
= 1) Bump memlock limits =
I have no idea, which one of these finally worked, and/or is sufficient.
A bit of a whack-a-mole.
cat >>/etc/security/limits.conf <<EOF
* soft memlock unlimited
* hard memlock unlimited
EOF
lxc config set nice-mako limits.kernel.memlock 33554432
mkdir -p /etc/systemd/system/snap.lxd.daemon.service.d/
cat >/etc/systemd/system/snap.lxd.daemon.service.d/override.conf <<EOF
[Service]
LimitMEMLOCK=6553600000
EOF
systemctl daemon-reload
systemctl restart snap.lxd.daemon.service
= 2) Bump rmem_max values =
Observed:
# strace -s99999 -f /usr/sbin/corosync 2>&1 | grep sockop
[pid 447] setsockopt(12, SOL_SOCKET, SO_RCVBUF, [8388608], 4) = 0
[pid 447] getsockopt(12, SOL_SOCKET, SO_RCVBUF, [425984], [4]) = 0
[pid 447] setsockopt(12, SOL_SOCKET, SO_RCVBUFFORCE, [8388608], 4) = -1 EPERM
(Operation not permitted)
Bumped mem_max using:
sudo sysctl -w net.core.wmem_max=8388608
sudo sysctl -w net.core.rmem_max=8388608
(Not sure if the desired sized depends on the machine/container I am
running on)
Can we check the values for above things on our armhf containers and/or bump
them? or like can we mark pacemaker v2.0 autopkgtest as ignored on armhf?
