Author	SHA1	Message	Date
Dustin	479a91ae79	Merge branch 'democratic-csi'	2025-09-07 10:25:14 -05:00
Dustin	67a1d8d0d5	democratic-csi: Enable volume resize _democratic-csi_ can also dynamically resize Synology iSCSI LUNs when PVC resource requests increase. This requires enabling the external resizer in the controller pod and marking the StorageClass as supporting resize.	2025-09-06 23:49:53 -05:00
Dustin	d909fc0566	democratic-csi: Enable volume snapshot support The _democratic-csi_ controller can create Synology LUN snapshots based on VolumeSnapshot resources. This feature can be used to e.g. create data snapshots before upgrades, etc.	2025-09-06 23:43:25 -05:00
Dustin	f3798c49e3	democratic-csi: Initial deployment Deploying _democratic-csi_ to manage PersistentVolumeClaim resources, mapping them to iSCSI volumes on the Synology. Eventually, all Longhorn-managed PVCs will be replaced with Synology iSCSI volumes. Getting rid of Longhorn should free up a lot of resources and remove a point of failure from the cluster.	2025-09-06 22:57:05 -05:00
