NFS Ganesha in mdcache_avl_qp_lookup_s()
by Krishna Harathi
Frank,
Long time. We are seeing a crash shown below. After seeing the fix in this commit - https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/516675,
I am posting a possible fix.

Possible fix –
diff mdcache_avl.c mdcache_avl.c.new

> memset(&v, 0, sizeof(v));

I also suggest reviewing all callers of this avltree_lookup() for potential similar problems. Comments?
Regards.

Re: Ganesha crash while doing Delegation recall

Delegations have not really been tested in quite some time.

Frank,
A question regarding the status of delegation on recent releases. Are the delegations supported or tested thoroughly in 4.0.5 or 3.5 Ganesha release.

V2.8 is pretty old and no longer supported. Additionally, I don’t know if delegations have been tested or supported recently at all so I doubt there’s any fixes but you could certainly try a newer release, or look through the git history.

Change in ...nfs-ganesha[next]: EXPORT: Decrease the default Prefer Read/Write size
by vicente (GerritHub)
vicente has uploaded this change for review. ( https://review.gerrithub.io/c/ffilz/nfs-ganesha/+/537606 )
Change subject: EXPORT: Decrease the default Prefer Read/Write size
......................................................................
EXPORT: Decrease the default Prefer Read/Write size
- For some older nfs client, e.g. libnfs 1.x,
could not handle the read/write size more
than 1M. Just decrease the default prefer
read/write size to 1M for general nfs client.
