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 34a016bdac Ignore errors restarting libvirtd 
This seems to inexplicably fail sometimes. We can just ignore it.

Joshua Boniface 2c0e09f657 Add setting bridge_mtu to config 2021-10-09 19:29:22 -04:00
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.

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.

Joshua Boniface 2e9d02ab52 Add additional CMK checks 2021-08-21 15:41:44 -04:00
Joshua Boniface b37d6c3009 Wait longer when restarting services 
From 15 -> 30 seconds to ensure more time for stabilization before
proceeding with the next.
 2021-07-30 11:46:49 -04:00
Joshua Boniface b62731199f Add default features flag to ceph.conf generator 
Coupled with the removal of explicit --image-features flags to the RBD
command in PVC itself, this ensures that only the two features supported
on kernel 4.19 are enabled by default.

Joshua Boniface 13dd41bb3e Add some Zookeeper configuration tweaks 2021-07-19 16:31:40 -04:00
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 
The Zookeeper daemon does not appear to exit with any status other than
0, even after a fatal error. Work around this.
 2021-07-19 13:03:09 -04:00
Joshua Boniface bd4d94568e Add -XX:+AlwaysPreTouch option for Zookeeper 2021-07-19 12:46:21 -04:00
Joshua Boniface e232ab00da Lower keep count for Zookeeper vacuum to 3 
Required to keep disk space growth down when using zookeeper_logging
functionality.

Joshua Boniface 6396eaa5ff Ensure libvirtd restarts when unit changes 2021-06-22 03:15:23 -04:00
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.

Avoids an issue where the pvcnoded service is stopped on non-bootstrap
runs.

Joshua Boniface 1c05c8729f Fix incorrect systemd enabling in Patroni 2021-01-28 16:28:02 -05:00
Joshua Boniface 04ca8f73d2 Correct bugs during bootstrap 
1. Ensure Zookeeper restarts and checks out successfully before
proceeding with other steps.
2. Make sure PVC itself doesn't start prematurely.

Joshua Boniface b7f251ea16 Retry pgsql bootstrap startup 6 times

Joshua Boniface 8e104113d7 Tune Zookeeper memory usage

Joshua Boniface de04105a38 Add tuning for Ceph OSDs 2020-12-21 00:20:45 -05:00
Joshua Boniface 28c86d170f Don't use libjemalloc for Ceph daemons 
This was an artifact of a much, much older Ceph configuration I ran, and
is not relevant with newer Ceph versions like those used in PVC.
Performance testing with Nautilus and Bluestore reveals a minimal
performance hit, and using `jemalloc` prevents cache autotuning from
being effective, so remove it.
