Subject: [PATCH 115/124] core: only log seek errors if SEEK_HOLE/SEEK_DATA is
|
|
|
74b1de |
available
|
|
|
74b1de |
|
|
|
74b1de |
On RHEL-6 there is no support for SEEK_HOLE/SEEK_DATA and this causes
|
|
|
74b1de |
the POSIX xlator to return errno=EINVAL. Because of this, the rpc-server
|
|
|
74b1de |
xlator will log all 'failed' seek attempts. When applications call
|
|
|
74b1de |
seek() often, the brick logs can grow very quickly and fill up the
|
|
|
74b1de |
disks.
|
|
|
74b1de |
|
|
|
74b1de |
Messages that get logged are like
|
|
|
74b1de |
[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]
|
|
|
74b1de |
|
|
|
74b1de |
The problem can be reproduced by running a Gluster Server on RHEL-6,
|
|
|
74b1de |
with a client running on RHEL-7. The client should execute an
|
|
|
74b1de |
application that calls lseek() with SEEK_HOLE/SEEK_DATA.
