NFS4 : NFS4ERR_REP_TOO_BIG_TO_CACHE response on CB_RECALL request from NFS server

Solution In Progress - Updated -

Issue

RHEL NFS client returns NFS4ERR_REP_TOO_BIG_TO_CACHE to a CB_RECALLrequest from NFS server. As a result, the delegation granted by the server in the past and now recalled is not returned. This can cause further problems on other clients that may see the file as locked or wait for access to be released (NFS4ERR_DELAY), until delegation is voluntary returned for client.

Environment

  • RHEL7, 8
