Joshua Boniface 980ea6a9e9 Adjust handling of ext_db and _count options
Avoid the use of superfluous flag options, default them to none, and add
support for fixed-size DB LVs.

Joshua Boniface 526a5f4a74 Add support for split OSD adds
Allows creating multiple OSDs on a single (NVMe) block device,
leveraging the "ceph-volume lvm batch" command. Replaces the previous
method of creating OSDs.

Also adds a new ZK item for each OSD indicating if it is split or not.

Joshua Boniface 38abd078af Export backup images to a tar archive
This helps ensure an easier restore as the tar archive(s) can be sent
directly to the API via the normal process of image uploading, instead
of individual disks.

Joshua Boniface a0b45a2bcd Always create RBDs with bytes value
Converting into human results in imprecise values when specifying bytes
directly, which in turn breaks VMDK image uploads. Instead, just use the
raw bytes value when creating the volume instead of converting it back.

Joshua Boniface 38d63d9837 Flip behaviour of memory selectors
It didn't make any sense to me for mem(prov) to be the default selector,
since this has too many caveats versus mem(free). Switch to using
mem(free) as the default (i.e. "mem") and make memprov the alternative.

Joshua Boniface bcabd7d079 Always sort VM list
Same justification as previous commit.
2022-08-09 12:05:40 -04:00
Joshua Boniface 05a316cdd6 Ensure the node list is sorted
Otherwise the node entries could come back in an arbitrary order; since
this is an ordered list of dictionaries that might not be expected by
the API consumers, so ensure it's always sorted.
2022-08-09 12:03:49 -04:00
Joshua Boniface d8d3feee22 Add selector help and adjust flag name
1. Add documentation on the node selector flags. In the API, reference
the daemon configuration manual which now includes details in this
section; in the CLI, provide the help in "pvc vm define" in detail and
then reference that command's help in the other commands that use this
field.

2. Ensure the naming is consistent in the CLI, using the flag name
"--node-selector" everywhere (was "--selector" for "pvc vm" commands and
"--node-selector" for "pvc provisioner" commands).

2022-05-06 15:40:52 -04:00
Joshua Boniface 7a40c7a55b Add support for replacing/refreshing OSDs
Adds commands to both replace an OSD disk, and refresh (reimport) an
existing OSD disk on a new node. This handles the cases where an OSD
disk should be replaced (either due to upgrades or failures) or where a
node is rebuilt in-place and an existing OSD must be re-imported to it.

This should avoid the need to do a full remove/add sequence for either
case.

Also cleans up some aspects of OSD removal that are identical between
methods (e.g. using safe-to-destroy and sleeping after stopping) and
fixes a bug if an OSD does not truly exist when the daemon starts up.
2022-05-06 15:32:06 -04:00
Joshua Boniface 464f0e0356 Store additional OSD information in ZK
Ensures that information like the FSIDs and the OSD LVM volume are
stored in Zookeeper at creation time and updated at daemon start time
(to ensure the data is populated at least once, or if the /dev/sdX
path changes).

This will allow safer operation of OSD removals and the potential
implementation of re-activation after node replacements.

Joshua Boniface 4d698be34b Add OSD removal force option
Ensures a removal can continue even in situations where some step(s)
might fail, for instance removing an obsolete OSD from a replaced node.

Joshua Boniface 1142454934 Add pool PGs count modification
Allows an administrator to adjust the PG count of a given pool. This can
be used to increase the PGs (for example after adding more OSDs) or
decrease it (to remove OSDs, reduce CPU load, etc.).

Joshua Boniface 25fe45dd28 Add device class tiers to Ceph pools
Allows specifying a particular device class ("tier") for a given pool,
for instance SSD-only or NVMe-only. This is implemented with Crush
rules on the Ceph side, and via an additional new key in the pool
Zookeeper schema which is defaulted to "default".
2021-12-28 20:58:15 -05:00
Joshua Boniface 6ccd19e636 Standardize fuzzy matching and use fullmatch
Solves two problems:

1. How match fuzziness was used was very inconsistent; make them all the
same, i.e. "if is_fuzzy and limit, apply .* to both sides".

2. Use re.fullmatch instead of re.match to ensure exact matching of the
regex to the value. Without fuzziness, this would sometimes cause
inconsistent behavior, for instance if a limit was non-fuzzy "vm",
expecting to match the actual "vm", but also matching "vm1" too.

Joshua Boniface 0d857d5ab8 Use positive check rather than negative
Ensure the VM is start before doing shutdown/stop, rather than being
stopped. Prevents overwrite of existing disable state and other
weirdness.
2021-11-06 04:08:33 -04:00
Joshua Boniface 5f193a6134 Perform automatic shutdown/stop on VM disable
Instead of requiring the VM to already be stopped, instead allow disable
state changes to perform a shutdown first. Also add a force option which
will do a hard stop instead of a shutdown.

Joshua Boniface 50d8aa0586 Add handlers for client network MTUs
Refactors some of the code in VXNetworkInterface to handle MTUs in a
more streamlined fashion. Also fixes a bug whereby bridge client
networks were being explicitly given the cluster dev MTU which might not
be correct. Now adds support for this option explicitly in the configs,
and defaults to 1500 for safety (the standard Ethernet MTU).

Joshua Boniface c0f7ba0125 Add limit negation to VM list
When using the "state", "node", or "tag" arguments to a VM list, add
support for a "negate" flag to look for all VMs *not in* the state,
node, or tag state.
2021-10-07 11:50:52 -04:00
Joshua Boniface 65df807b09 Add support for configurable OSD DB ratios
The default of 0.05 (5%) is likely ideal in the initial implementation,
but allow this to be set explicitly for maximum flexibility in
space-constrained or performance-critical use-cases.
2021-09-24 01:06:39 -04:00
Joshua Boniface adc8a5a3bc Add separate OSD DB device support
Adds in three parts:

1. Create an API endpoint to create OSD DB volume groups on a device.
Passed through to the node via the same command pipeline as
creating/removing OSDs, and creates a volume group with a fixed name
(osd-db).

2. Adds API support for specifying whether or not to use this DB volume
group when creating a new OSD via the "ext_db" flag. Naming and sizing
is fixed for simplicity and based on Ceph recommendations (5% of OSD
size). The Zookeeper schema tracks the block device to use during
removal.

3. Adds CLI support for the new and modified API endpoints, as well as
displaying the block device and DB block device in the OSD list.

While I debated supporting adding a DB device to an existing OSD, in
practice this ended up being a very complex operation involving stopping
the OSD and setting some options, so this is not supported; this can be
specified during OSD creation only.

Closes #142
2021-09-23 13:59:49 -04:00
Joshua Boniface 58db537093 Add memory and vCPU checks to VM define/modify
Ensures that a VM won't:

(a) Have provisioned more RAM than there is available on a given node.
Due to memory overprovisioning, this is simply a "is the VM memory count
more than the node count", and doesn't factor in free or used memory on
a node, total cluster usage, etc. So if a node has 64GB total RAM, the
VM limit is 64GB. It is up to an administrator to ensure sanity *below*
that value.

(b) Have provisioned more vCPUs than there are CPU cores on the node,
minus 2 to account for hypervisor/storage processes. Will ensure there
is no severe CPU contention caused by a single VM having more vCPUs than
there are actual execution threads available.

Joshua Boniface e962743e51 Add VM device hot attach/detach support
Adds a new API endpoint to support hot attach/detach of devices, and the

network/storage add/remove actions.

The live attach is now the default behaviour for these types of
additions and removals, and can be disabled if needed.

Prevents bad states where the VM is "removed" but some of its disks

Joshua Boniface 80f04ce8ee Remove connection renewal in state handler
Regenerating the ZK connection was fraught with issues, including
duplicate connections, strange failures to reconnect, and various other
wonkiness.

Instead let Kazoo handle states sensibly. Kazoo moves to SUSPENDED state
when it loses connectivity, and stays there indefinitely (based on
cursory tests). And Kazoo seems to always resume from this just fine on
its own. Thus all that hackery did nothing but complicate reconnection.

This therefore turns the listener into a purely informational function,
providing logs of when/why it failed, and we also add some additional
output messages during initial connection and final disconnection.

Joshua Boniface a8c28786dd Better handle empty ipaths in schema
When trying to write to sub-item paths that don't yet exist, the
previous method would just blindly write to whatever the root key is,
which is never what we actually want.

Instead, check explicitly for a "base path" situation, and handle that.
Then, if we try to get a subpath that isn't valid, return None. Finally
in the various functions, if the path is None, just continue (or return
false/None) and (try to) chug along.

This helps parallelize the numerous Zookeeper calls a little bit, at
least within the bounds of the GIL, to improve performance when getting
a large list of VMs. The max_workers value is capped at 32 to avoid
causing too many threads during concurrent executions, but still
provides a noticeable speedup (on the order of 0.2-0.4 seconds with 75
VMs, scaling up further as counts grow).

Joshua Boniface baf4c3fbc7 Add performance profiler function
Usable anywhere that the global daemon "config" parameter can be passed
in (e.g. pvcapid/helper.py, pvcnoded/Daemon.py, etc.). Stores results in
a subdirectory of the PVC logdir called "profiler" if this directory can
be created, or prints results.

The debug config parameter ensures that the profiler can be added to
functions and not run unless the server is explicitly in debug mode.
Might not be useful as I don't initially plan to add this to every
function (only when investigating performance problems), but this
flexibility allows that to change later.

Joshua Boniface e093efceb1 Add NoNodeError handlers in ZK locks
Instead of looping 5+ times acquiring an impossible lock on a
nonexistent key, just fail on a different error and return failure
immediately.

This is likely a major corner case that shouldn't happen, but better to
be safe than 500.

Joshua Boniface a080598781 Avoid superfluous ZK exists calls
These cause a major (2x) slowdown in read calls since Zookeeper
connections are expensive/slow. Instead, just try the thing and return
None if there's no key there.

Also wrap the children command in similar error handling since that did
not exist and could likely cause some bugs at some point.

Joshua Boniface f91c07fdcf Re-add UUID limit matching for full UUIDs
This *was* valuable when passing a full UUID in, so go back to that.
Verify first that the limit string is an actual UUID, and then compare
against it if applicable.
2021-06-28 12:27:43 -04:00
Joshua Boniface c54f66efa8 Limit match only on VM name
I can see no possible reason to want to do limits against UUIDs, but
supporting that means match is not what one would expect since a random
UUID could match the limit. So only limit based on the name.

Joshua Boniface cd860bae6b Optimize VM list in API
With many VMs this slows down linearly. Rework it a bit so there are
fewer calls to getInformationFromXML and so the processing could happen
in parallel at some point.

Joshua Boniface 60e1da09dd Don't try any shenannegans when updating NICs
Trying to do this on the VMInstance side had problems because we can't
differentiate the 3 types of migration there. So, just update this in
the API side and hope everything goes well.

This introduces an edge bug: if a VM is using a macvtap SR-IOV device,
and then tries to migrate, and the migrate is aborted, the NIC lists
will be inconsistent.

When I revamp the VMInstance in the future, I should be able to correct
this, but for now we'll have to live with that edgecase.

Joshua Boniface e7b6a3eac1 Implement SR-IOV PF and VF instances
Adds support for the node daemon managing SR-IOV PF and VF instances.

PFs are added to Zookeeper automatically based on the config at startup
during network configuration, and are otherwise completely static. PFs
are automatically removed from Zookeeper, along with all coresponding
VFs, should the PF phy device be removed from the configuration.

VFs are configured based on the (autocreated) VFs of each PF device,
added to Zookeeper, and then a new class instance, SRIOVVFInstance, is
used to watch them for configuration changes. This will enable the
runtime management of VF settings by the API. The set of keys ensures
that both configuration and details of the NIC can be tracked.

Most keys are self-explanatory, especially for PFs and the basic keys
for VFs. The configuration tree is also self-explanatory, being based
entirely on the options available in the `ip link set {dev} vf` command.

Two additional keys are also present: `used` and `used_by`, which will
be able to track the (boolean) state of usage, as well as the VM that
uses a given VIF. Since the VM side implementation will support both
macvtap and direct "hostdev" assignments, this will ensure that this
state can be tracked on both the VF and the VM side.
