Hi all,
I'm running
#: glusterfs -V

on ubuntu 14.04 from the semiosis ppa
I have a replica 2 with 2 servers
another client does a fuse mount of a volume.
On rsyncing a bit of data onto the fuse mount,
I get an entry like the below one on the client - for each file that
is copied onto the volume
[2014-09-19 07:57:39.877806] W
[client-rpc-fops.c:1232:client3_3_removexattr_cbk]
0-<volume_name>-client-0: remote operation failed: No data available
[2014-09-19 07:57:39.877963] W
[client-rpc-fops.c:1232:client3_3_removexattr_cbk]
0-<volume_name>-client-1: remote operation failed: No data available
[2014-09-19 07:57:39.878462] W [fuse-bridge.c:1172:fuse_err_cbk]
0-glusterfs-fuse: 21741144: REMOVEXATTR()
/<path_to_file>/.<file_name_with_a_leading_dot> => -1 (No data available)
The data itself is present and accessible on the volume and on both bricks.
So three questions:
a.) what kind of data is not available? what is the client complaining
about?
This problem is being seen for a removexattr() operation. The client
would have sent a request for an extended attribute to be removed from a
file or directory. No data available/ENODATA error is seen when the file
or directory does not have the key of the extended attribute which was
requested to be removed. Performing strace of rsync might give a clue
about the key of the extended attribute.
b.) since it is a warning and the data seems to be okay - is there
anything I need to fix?
Usually this warning is benign in nature.
c.) How can I get rid of the amount of log lines? it's more than 3GB/day..
You can possibly have a logrotate policy to rotate based on the size of
the log file.
I have sent across a patch to avoid flooding logs with removexattr
warning messages when the error happens to be ENODATA or ENOATTR [1].
