Joshua Boniface bb3b7e3922 Fix a few more splits 2021-11-11 17:37:27 -05:00
Joshua Boniface 414678f683 Fix a few more extraneous splits 
Just use this_node if applicable, or the raw node.hostname.
 2021-11-11 17:35:42 -05:00
Joshua Boniface b24e539252 Remove extraneous splits 
The node.hostname should always be short.
 2021-11-11 17:31:56 -05:00
Joshua Boniface 243c910d6d Unify and standardize inventory_hostname 
This was causing some confusing conflicts, so create a new fact called
"this_node" which is inventory_hostname.split('.')[0], i.e. the short
name, and use that everywhere instead of an FQDN or true inventory
hostname.

Joshua Boniface fed71d7add Add option for setting CPU governor 
Allows the administrator to set a CPU frequency governor if they need
to, though the default of ondemand is usually sufficient.

Joshua Boniface 34a016bdac Ignore errors restarting libvirtd

Joshua Boniface 739c60fce0 Add resolv.conf customization 2021-10-11 14:41:29 -04:00
Joshua Boniface 3de777a036 Disable unified cgroup heirarchy on kernel cmdline 
This is required on Debian 11 to use the cset tool, since the newer
systemd implementation of a unified cgroup hierarchy is not compatible
with the cset tool.

Ref for future use:

Joshua Boniface 5797535997 Adjust documentation and behaviour of cpuset 
1. Detail the caveats and specific situations and ref the documentation
which will provide more details.

2. Always install the configs, but use /etc/default/ceph-osd-cpuset to
control if the script does anything or not (so, the "osd" cset set is
always active just not set in a special way.
 2021-09-29 20:49:00 -04:00
Joshua Boniface 81cf341c32 Install cset configs even if disabled 
The setup script handles this instead.
 2021-09-29 10:23:01 -04:00
Joshua Boniface 645249b57e Allow dynamic enabling/disabling of cset 
Add a separate config to handle enable/disable on the system itself.
 2021-09-29 10:21:47 -04:00
Joshua Boniface 8ac2a5ea0c Adjust default ceph.conf parameters 
1. Remove an explicit OSD journal size, especially such a small one (no
clue why I ever added that...)

2. Add max scrubs, disable scrub during recovery, and set scrub sleep.

3. Add max backfills, tune recovery sleep to 0 to prioritize recovery.
 2021-09-28 02:09:50 -04:00
Joshua Boniface 732bfe732c Add Ceph OSD cpuset tuning options 
Allows an administrator to set CPU pinning with the cpuset tool for Ceph
OSDs, in situations where CPU contention with VMs or other system tasks
may be negatively affecting OSD performance. This is optional, advanced
tuning and is disabled by default.

proceeding with the next.
 2021-07-30 11:46:49 -04:00
Joshua Boniface b62731199f Add default features flag to ceph.conf generator

command in PVC itself, this ensures that only the two features supported
on kernel 4.19 are enabled by default.

Joshua Boniface f294817b55 Disable any systemd start rate limiting 
Because Zookeeper is supremely stupid (see last commit) we want to
disable start limiting. It needs to keep trying forever until it starts.
 2021-07-19 13:21:16 -04:00
Joshua Boniface b112663ef0 Ensure Zookeeper restarts itself

Joshua Boniface ec879f4e3c Add override custom libvirtd.service unit 
This has no functional change on Buster, but on Bullseye this overrides
the stupid socket-based activation shenanigans that the default unit
tries to do, as well as the breaking replacement of the
/etc/default/libvirt variable names.

Joshua Boniface e76832de91 Allow inter-cluster orphan NTP sync 
Due to the requirement of Ceph to have all peer nodes tightly
synchronized with each other to come online, PVC nodes need a way to
synchronize to each other even in the absence of an external time
reference. This is especially prevalent if a set of nodes are left
offline for an extended period (>1-2 weeks), since their hardware clocks
will drift. If the resulting Internet connectivity is then dependent on
a VM, this will cause a catch-22 and the cluster will not properly
start.

This configuration will accomplish that - if no suitable >6 stratum
peers are found, the hosts will enter orphan mode. Since they are now
all configured as "peers" with each other, they will collectively decide
on one of them to become the source and sync to it. A local stratum 10
fudge is added so that at least one of the nodes can become this source.

While this is not an ideal use of NTP, it is by far the cleanest
solution to this problem, and does not impact normal functionality when
the two configured stratum-2 servers are reachable.
