FSAL cache cleanup - How to drop in-mem caches at nfs-ganesha
Hi, I have a requirement in my FSM to invalidate the cache. While doing it I want to nfs-ganesha to drop any in-memory cache for the given export. How can I inform nfs-ganesha to drop all in-memory caches for the given export? Regards, Shahid Shaikh.
Currently, there's no way to do this. You can invalidate the metadata cache for a single object with an UP-call (the invalidate() call) but there is no way to recursively invalidate, and no UP-call to remove a handle-cache entry at all. This last would chancy anyway, since anything with a ref on that entry would keep it around regardless of any UP-call. However, once the underlying inode for an entry is gone, the first use of it will return ESTALE, causing the entry to be removed ASAP. Daniel On 07/25/2018 10:03 AM, sshaikh@commvault.com wrote:

Thanks Daniel. How long nfs-ganesha will wait before validating the cache for given gid against the underlying inode?
The next time that inode is used. There's no background validation. Daniel On 07/26/2018 01:44 AM, sshaikh@commvault.com wrote:
