If it could be downsized it would be great for us (another team) |
|
@orloffv Downsize is kinda tricky operation, there are many things that could go wrong. I think it would be better to request/implement it via separated feature request |

We need to add isolated e2e test for resize device command to test resize independently from csi driver. |

issue: #1657 Discussion: #1748 (comment) RefreshEndpoint was introduced to notify endpoints about new size of the volume: https://github.com/ydb-platform/nbs/blob/main/cloud/blockstore/libs/endpoints_vhost/vhost_server.cpp#L66 We can use it to resize nbd device instead of separate ResizeDevice method. ResizeDevice will be removed in another PR.

issue: #1657 Support pvc resize with minikube/nbsd-lightweight Update minikube manifests: Add csi-resizer sidecar to csi controller Allow to expand volume Increase pvc storage limit as it is not possible to expand volume beyond the limit Fix volume resize in nbsd-lightweight. Old blocks count value was cached in several places: mounted volume, storage and storage adapter. Fixed by recreating storage/storage adapter.

We need NBS disks mounted in
Filesystemmode via CSI to support online resize up (allowVolumeExpansionstorageclass feature), in order to provide our services a possibility to scale up underlying storage by a client's request.Please help to implement it.
Many thanks!
