This topic describes the information that you must take note of when you use File Storage NAS (NAS) volumes in ACK Serverless (ASK) clusters.
NAS is a shared storage service. A persistent volume claim (PVC) that is used to mount a NAS file system can be used by multiple pods.
Do not delete the mount target before you unmount the NAS file system. Otherwise, an operating system hang issue may occur.
After a mount target is created, wait until its status changes to Available and then use the volume.
We recommend that you use the NFSv3 file sharing protocol.
General-purpose and Extreme NAS file systems have different limits on mounting scenarios, the number of file systems, and file sharing protocols. For more information, see Limits.
After you delete a persistent volume (PV) of the subpath type in an ACK Serverless cluster, the subdirectory is not deleted. This means that even if the
reclaimPolicyof a PV is set toDeleteand the PV is deleted, the corresponding directory in the NAS file system is not deleted. You need to manually mount the subdirectory and delete it.
