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.

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.

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 9b103f48ad Update default repo domain 
We now have parallelvirtualcluster.org set up, so use that instead of
the bonifacelabs domain.

Joshua Boniface b37d6c3009 Wait longer when restarting services 
From 15 -> 30 seconds to ensure more time for stabilization before
proceeding with the next.

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 311f388f56 Increase flush/unflush wait timeout 
Bump this from 10 minutes (60 * 10 seconds) to 30 minutes (180 * 10
seconds) to ensure there is sufficient time for (relatively) large VMs
to migrate with (relatively) slow networking.

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.

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.
