[Gluster-users] periodical warnings in brick-log after upgrading to gluster 7.1

[Michael Böhm]

Hello,

i've finally upgraded our gluster-server to 7.1 (3.8 debian stretch ->
gluster-repo 3.12 -> gluster-repo 7.1) and it actually went real smooth.
There is just that warning in all brick-logs and every server every 15min i
can't really explain myself.

[2019-12-29 05:51:17.807293] W [socket.c:774:__socket_rwv]
0-tcp.store4-server: readv on 192.168.31.60:49077 failed (no data available)
[2019-12-29 06:00:47.886369] W [socket.c:774:__socket_rwv]
0-tcp.store4-server: readv on 192.168.31.61:49140 failed (no data
available)
[2019-12-29 06:06:18.204778] W [socket.c:774:__socket_rwv]
0-tcp.store4-server: readv on 192.168.31.60:49077 failed (no data

.60 and .61 are two servers with bricks for gluster volume "store4". They
are not only the gluster-server, they also are clients that mount the
gluster volumes. (replicated gluster volume, that hosts kvm images that run
locally on the server)

Everything really looks good no other errors or warning - just the lines
mentioned above. Is this something i should be worried about or can resolve
somehow?

Of course i looked through the web, unfortunately i only really could find
one guy that had the same problem but no following messages [1]. And the
best explanation i could find was in a bug report [2], so it seems it's not
unusual i just don't like ignoring warnings.

Anyone here that has similiar warning or could explain what i can do about
it?

Thanks Mika
