Joshua Boniface 553c1e670e Add VM snapshots functionality
Adds the ability to create snapshots of an entire VM, including all its
RBD disks and the VM XML config, though not any PVC metadata.

Joshua Boniface 5d0e7931d1 Add support for rolling back snapshots
We supported creating snapshots, but not doing anything with them. This
removes the manual task of restoring a snapshot and replace it with a
PVC abstraction of rolling back to a snapshot.

While Ceph recommends cloning a snapshot instead of rolling back, due to
the time taken, in our usecase I don't think that is an optimal
strategy, as it will leave dangling clones that we'd then have to
manage.

Closes #183

Joshua Boniface a95e72008e Add size validations for volume clones
Adds the same validations as a volume add or resize to volume clones, to
ensure there is enough free space for them.
2024-02-02 11:37:29 -05:00
Joshua Boniface efc7434143 Add safety check for 80% full size
Adds a check that a volume creation or resize won't violate the 80% full
rule for the storage cluster. This ensures a cluster won't get too full
if a storage volume fills up.

Also adds a force flag throughout the pipeline to override this check,
should an administrator really want to do so.

Closes #177

Joshua Boniface 09269f182c Add live migrate max downtime selector meta field
Adds a new flag to VM metadata to allow setting the VM live migration
max downtime. This will enable very busy VMs that hang live migration to
have this value changed.

Joshua Boniface 64e37ae963 Update OSD replacement functionality
1. Simplify this by leveraging the existing remove_osd/add_osd
functions, since its task was functionally identical to those two in
sequential order.
2. Add support for split OSDs within the command (replacing all OSDs on
the block device(s) as required).
3. Add additional configurability and flexibility around the old device,
weight, and external DB LVs.

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 35e27f79ef Fix uploading of non-raw image files
Adds a new API query parameter to define the file size, which is then
used for the temporary image. This is required for, at least VMDK, files
to work properly in qemu-img convert.

Joshua Boniface c401a1f655 Use consistent language for primary mode
I didn't call it "router" anywhere else, but the state in the list is
called "coordinator" so, call it "coordinator mode".

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 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.
2022-04-29 11:16:33 -04:00
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.).
2021-12-28 21:53:29 -05:00
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".

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 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.

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.
