Description Kinglong Mee 2019-06-25 01:36:50 UTC

Description of problem:

I have a 4+2 ec volume, and a fault inject test (reboot a ec node every 600s),
nfs client runs the fs_racer test of ltp.

The ganesha.nfsd prints some logs in ganesha.log,

ganesha.nfsd-19199[work-8] posix2fsal_type :FSAL :WARN :Unknown object type: 0

and logs in ganesha-gfapi.log,

[dht-selfheal.c:668:dht_selfheal_dir_xattr_cbk] 0-test1-dht: layout setxattr failed on test1-disperse-0, path:/nfsshare/ltp-Fa5fNeMmWI/race/14/14 gfid:c51c4be6-b9a4-4cc0-96fd-f069018bf9d7 [No such file or directory]

When meeting error, dht_selfheal_dir_xattr_cbk just return 0 to up layer
that causes gfapi return success at mkdir with empty stat.
