Ports we care about
Porto Number Used by Nets Description
TCP 2224 pcsd bcn It is crucial to open port 2224 in such a way that pcs from any node can talk to all nodes in the cluster, including itself.
UDP 5404 corosync bcn Required on corosync nodes if corosync is configured for multicast UDP
UDP 5405 corosync bcn Required on all corosync nodes (needed by corosync)
TCP 7788+ drbd sn 1 port per resource
TCP 49152-49215 virsh bcn live migration - migration_port_min and migration_port_max attributes in the /etc/libvirt/qemu.conf
NOTE: DHCP listens to raw sockets and ignores firewalld rules. We need to stop dhcpd directly - https://kb.isc.org/docs/aa-00378
* After all changes;
firewall-cmd --zone=public --add-port=49152-49215/tcp --permanent
firewall-cmd --reload
- Paths
If we want to create services or helpers later, look under - /usr/lib/firewalld/
Core firewalld configs, including defaults zones, etc - /etc/firewalld/
* Zones are meant to deal with dynamic environments and aren't that useful in mostly static server environments
* Use 'firewall-cmd' WITHOUT '--permanent' for things like enabling the VNC port for a server. Use '--permanent' for everything else.

DB stuff;
Dump;
su - postgres -c "pg_dump anvil" > /anvil.out
Drop;
su - postgres -c "dropdb anvil" && su - postgres -c "createdb --owner admin anvil" && su - postgres -c "psql anvil"
Reload the DB;
su - postgres -c "dropdb anvil" && su - postgres -c "createdb --owner admin anvil" && su - postgres -c "psql anvil < /anvil.out"
su - postgres -c "psql anvil"
Changes made using tools such as nmcli do not require a reload but do require the associated interface to be put down and then up again. That can be done by using commands in the following format:
* nmcli dev disconnect interface-name
Followed by:
* nmcli con up interface-name
NOTE: RHEL doesn't support direct-cabled bonds - https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/networking_guide/ch-configure_network_bonding

iface
* PREFIXx overrules NETMASKx. Use PREFIXx, not NETMASKx.
* The 'x' suffice for PREFIX, NETMASK, etc start at 0 and must count up by 1 at a time.
* ZONE will be useful for the firewall stuff later.
* ETHTOOL_OPTS is deprecated, replaced by using udev rules
* initscripts interpret PEERDNS=no to mean "never touch resolv.conf". NetworkManager interprets it to say "never add automatic (DHCP, PPP, VPN, etc.) nameservers to resolv.conf".
Bond
* resend_igmp & num_unsol_na={1~255} may help if a switch is slow to notice traffic has moved to the new interface. default is 1. Each update is send 200ms apart.
* Bridged interfaces should use BRIDGE_UUID="", _not_ BRIDGE="". The former causes the later to be ignored and the later is only used for possible compatibility reasons.
Bridge
* STP=no is default, we'll test 'yes'.
* DOMAIN="<client_domain>"

==== DRBD notes
* resources can contain an US-ASCII character, except for spaces
* A resource is a single replication stream for 1 or more resources, max 65.535 vols per resource
* DRBD does, however, ship with an LVM integration facility that automates the creation of LVM snapshots immediately before synchronization. This ensures that a consistent copy of the data is always available on the peer, even while synchronization is running. See Using automated LVM snapshots during DRBD synchronization for details on using this facility.
** https://docs.linbit.com/docs/users-guide-9.0/#s-lvm-snapshots
* Checksum-based synchronization computes a block's hash on source and target and skips if matching, possibly making resync much faster for blocks rewritten with the same data, but at the cost of CPU. Make this a user-configurable option under the advanced tab.
* Suspended replication allows congested replication links to suspend replication, leaving the peer in a consistent state, but allowing the primary to "pull ahead". When the congestion passes, the delta resyncs. Make this a user-configurable option with scary warnings.
* Online verification can (should?) be run periodically on the server host (verification source will overwrite deltas on the verification target). Perhaps schedule to run once/month? Do resource sequentially as this places a CPU load on the nodes.
* Replication traffic integrity checking uses a given available kernel crypto to verify data integrity on transmission to the peer. If the replicated block can not be verified against the digest, the connection is dropped and immediately re-established; because of the bitmap the typical result is a retransmission.
** Make an option in the advanced tab. Test to see overhead this adds. Choose the lowest overhead algo (within reason)
* Support for disk flushes might be something we want to disable, as it seems to force write-through even with a function FBWC/BBU. Need to test.
* Note; "Inconsistent" is almost always useless. "Consistent" and "Outdated" are able to be used safely, just without whatever happened on the peer after.
* Truck based replication, also known as disk shipping, is a means of preseeding a remote site with data to be replicated, by physically shipping storage media to the remote site.
* Make sure that selinux doesn't block DRBD comms over the SN
* See "5.15.1. Growing on-line" for growing a DRBD resource
** Shrinking online is ONLY possible if the metadata is external. Worth creating *_md LVs? Offline requires backing up and restoring the MD
Provisioning a server will need to:
* Open up a DRBD port (or more, if multiple resources are created).
* Create the DRBD resource(s); Find the lowest free rX.res, create it locally and on the peer (if up),
firewall-cmd --zone=public --permanent --add-port=7788-7790/tcp
firewall-cmd --reload
* Provision the server via virt-install
* push the new XML to striker such that the peer's anvil daemon picks it up and writes it out.

Set the maximum migration bandwidth (in MiB/s) for a domain which is being migrated to another host. bandwidth is interpreted as an
unsigned long long value. Specifying a negative value results in an essentially unlimited value being provided to the hypervisor. The
hypervisor can choose whether to reject the value or convert it to the maximum value allowed.

== Resource Agent; https://github.com/ClusterLabs/resource-agents/blob/master/doc/dev-guides/ra-dev-guide.asc
* A resource agent receives all configuration information about the resource it manages via environment variables. The names of these environment variables are always the name of the resource parameter, prefixed with OCF_RESKEY_. For example, if the resource has an ip parameter set to 192.168.1.1, then the resource agent will have access to an environment variable OCF_RESKEY_ip holding that value.

When stopping a server;
14:03 < lge> "on-fail: block"
14:03 < lge> is per operation type.
14:08 < lge> anyways, you can also "on-fail: retry"
OK, set the stop timeout to 60, set 'on-fail: block" and set the failure-timeout to 60 and see how pacemaker reacts.

Migrate servers;
- Let ScanCore set 'node-health' attribute (http://clusterlabs.org/pacemaker/doc/en-US/Pacemaker/1.1/html-single/Pacemaker_Explained/index.html#s-node-health)
- Set 'migration-limit' to '1' to enforce serial live migration (http://clusterlabs.org/pacemaker/doc/en-US/Pacemaker/1.1/html-single/Pacemaker_Explained/index.html#s-cluster-options).
Migrate a single server by setting a location constraint against the node we want the VM off of.
- If anything goes wrong, the server will enter a blocked state in pacemaker.
- Recovery needs to be 'unmanage -> clean' to avoid a stop call.
11:57 <@kgaillot> for your design, that sounds right. between cleanup and manage, i'd make sure there was a PE run without any pending actions blocked by the unmanaging -- you can either look at the logs on the DC, run "crm_simulate -SL", or just check the status for a bit
11:58 <@kgaillot> you can play around with it by putting a higher preference on the to-be-cleaned node, to make sure it *does* move when you re-manage. that way you can see what logs/simulate/status look like
12:07 <@kgaillot> i'm thinking if you do crm_resource --reprobe instead of cleanup in the above sequence, that should prevent anything unexpected
12:07 <@kgaillot> unmanage -> adjust preferences if needed -> reprobe resource -> wait for probe results to come back in, and if status looks good -> re-manage
12:08 <@kgaillot> the reprobe will wipe the entire resource history and fail counts for the resource, causing pacemaker to recheck the current status on all nodes. if the status then shows the resource running where you expect/want it, with no errors, then it's not going to do anything further
12:09 <@kgaillot> (in 2.0, cleanup only erases the history where the resource has failed, while reprobe erases the history regardless)
12:13 <@kgaillot> if there are no failures in the resource history, there should be no risk of a full stop. if there is no resource history at all, then after reprobe, there should be no risk of any actions (assuming you've set up location preferences and stickiness how you want them)
Recover from a failed migration;
reset location to prefer current host -> unmanage resource -> cleanup resource -> manage resource
(running on node 2, so re-add location constraint - basically, make sure location constraint favours current host)
pcs resource unmanage srv01-c7
pcs constraint remove location-srv01-c7-m3-a02n02.alteeve.com-50
crm_resource --reprobe
pcs resource manage srv01-c7

Burst the source tarball;
do it again but stash this copy in a *-digimer directory.
Do patching in the -digimer directory and when finished great a recursive unified diff and place the results directly in the named .patch file.
