Volume Expansion about cloud-director-named-disk-csi-driver HOT 15 CLOSED

Hi @arunmk - we would prefer the ONLINE method of EXPAND_VOLUME with the subsequent NodeExpandVolume call to expand the filesystem. The main use-case is for database services, so we would not want to take these services offline to expand their storage.

I am testing the consistency of the data but I may have found a workaround which may work in some cases :

• Make be sure your retain poilcy are on Retain
• Scale all deployment who uses the volume to 0
• Edit PV and change size
• Edit PV via vCD to change size
• Save your PVC on a yaml file : k get pvc 'pvc-name' -o yaml > pvc-name.yaml
• Delete your PVC
• Edit PV and remove spec.claimRef part
• Edit your pvc file previously saved to change size
• Apply your pvc file : k apply -f pvc-name.yaml
• Scale your deployement to 1 or more
• Check on vCD on which worker node your pv is attach
• Login on SSH on worker node where the PV is
• find your volume with fdsik -l and run a resize2fs /dev/sdX

I have not yet found a solution to resize a volume if it is not possible to connect to ssh on the worker node (ssh key not provided in deployment wizard)

Thanks @jleavers. We will prioritize this.

Hi @arunmk - do you have an ETA as to when volume expansion will be available?

from cloud-director-named-disk-csi-driver.

@jleavers let me bring this up with the team and get back.

@jleavers will OFFLINE method of EXPAND_VOLUME satisfy your use-case?

This should be at least supported for RWO disks that is often used for stuff like Kafka, RDBMS etc.

Another customer of mine really prefers having ONLINE expansion capabilitie.
End customers are creating stateful workloads and want to start with small disk sizes and expand when needed.

Mee too, i use it with capvcd cluster deployment.
I would really appreciate this feature becoming available. I don't know the status is at the moment.

Hi @arunmk

Do you have an ETA, when at least offline expansion will be available? As @jleavers, we use it for database services and online expansion would be nice, but offline expansion is a step in the right direction.

Hi @arunmk

is there any progress on this ? This issue as well as the PR seem to be stale/stuck..
Online resize would be the preferred way, nobody wants downtimes for this type of change anymore...

from cloud-director-named-disk-csi-driver.

Here it seems to be done already, is this so different ?
Is it the cloud director part thats the problem ? or is it the part where the fs is expanded on the node ?
