Gluster.org Gerrit 22526 0 None Merged core: only log seek errors if SEEK_HOLE/SEEK_DATA is available 2019-04-11 04:37:43 UTC

Description Niels de Vos 2019-04-08 10:55:50 UTC 
Description of problem:
seeing thousands of SEEK* errors in two bricks' logs on one particular node, gluster02.example.com.

The following shows the start of the errors:

[server-rpc-fops.c:2091:server_seek_cbk] 0-vol01-server: 4947: SEEK-2 (53920aee-062c-4598-aa50-2b4d7821b204), client: worker.example.com-7808-2019/02/08-18:04:57:903430-vol01-client-0-0-0, error-xlator: vol01-posix [Invalid argument]

Version-Release number of selected component (if applicable):
glusterfs server 3.12.2 on el6

How reproducible:
Run an application on an el7 gluster client, against a glusterfs server on el6. The application should call lseek() with whence=SEEK_HOLE/SEEK_DATA.

Actual results:
glusterfs server on el6 fills the brick logs, disk can run out of space quickly

Expected results:
no logging if this is correct behaviour, limit logging in case it is an error.
