nfs: Introduce tunable for memory consumption

2011-01-12T07:58:33+00:00

NFS has used a common define called the mem-factor to determine
how much memory is allocated for the following items:

o inode table
o local structures used by nfs for storing fop state
o local structures used by nfs3 for storing nfs op state

These are all allocated through the mem-pool. The factor is multiplied by
a multiple that is specific to each data structure. For eg.

define GF_NFS_CONCURRENT_OPS_MULT     15
define GF_NFS_INODE_LRU_MULT          6000

The first value is used for allocating a mem-pool for storing
state for each fop or nfs op that is currently being handled. Knowing that linux
allows at most 128 in-flight requests, this multiple combined with the default
mem-factor of 15 gives us 225 slots in the mem-pool for the local structures.

Similarly, 6000*15 gives us a space of 90k inodes in the lru.

That means, increasing the common mem-factor will allow increasing the perf
under some conditions. This patch introduces the mem-factor as a configurable
option.

nfs3: Ignore requests for volumes without a single CHILD-UP

2011-01-08T01:43:56+00:00

NFS ignores the requests for subvolumes on which child-up has never been
received.

nfs: Support subdirectory exports

2010-12-29T18:20:36+00:00

Enable exporting directories as separate exports. Even though the directories
wont show up in showmount output, they'll still be mount'able.

The new option:

        nfs.export-dirs 

is enabled by default so that users dont have to wait till this option
is incorporated into the gluster command line.
