Description Raghavendra Bhat 2018-11-05 22:16:31 UTC
Description of problem:

   Currently, the snapdaemon can reach the lru limit of the inode table
    and start sending forgets on the inodes that are least recently used.
    snapview-server maintains the mapping between the domain of the
    snapdaemon and the gfapi instance which it uses to access the snapshots
    via a handle that is stored in the inode context of snapdaemon's inode.
    The handle is glfs_h_object structure which itself points to the actual
    inode present in the gfapi world.
    But, when snapview-server receives forget on a inode, it deleted the
    inode context without actually closing the handle it had obtained to
    map the inode from snapdaemon to the inode in gfapi world.
