Comment 1 Nithya Balachandran 2017-05-18 13:45:41 UTC

This should be fixed with
https://review.gluster.org/#/c/17312

The dht_local_init was modified to remove a recently added line of code:

local->hashed_subvol = dht_subvol_get_hashed (frame->this, loc);

Comment 2 vlad 2018-01-26 03:41:18 UTC

Comment 3 Nithya Balachandran 2018-01-28 12:56:37 UTC

This appears to be originating from the nufa translator. We don't currently support this translator.
