[Gluster-users] glusterfs and glusterfsd process utilization
Hi Krutika,
Thank you so much for the response. I'm starting to get a bit desperate :-)
I'm not sure which file is the brick log but the client log (I assume that
is the one that start with mnt-) is far too large to include. If you can
tell me what it is, perhaps we can arrange to get it to you using some
other method?
Anyway, I primarily see the following messages in what I believe to be the
client log.
The first is as mentioned earlier and repeated again here:
[2014-12-21 05:33:49.873989] I [dict.c:370:dict_get] (-->
/usr/lib64/libglusterfs.so.0(_gf_log_callingfn+0x1e0)[0x7fe3bd0d2420] (-->

This seems to be the one I see the most when it is starting up and having
this issue but I can't be certain. By the way, can you tell me what that
means?
The second entry I see often in the log files is in regards to missing
files such as follows:
[2014-12-22 02:33:32.062741] I [dht-common.c:1822:dht_lookup_cbk]
0-gv0-dht: Entry /html/some_dir/some_file/asdf.php missing on subvol
gv0-replicate-0
I thought these might be causing my problems but I see them all the time,
including right now and process utilization on the servers in this cluster
is currently way down next to nothing so I no longer think that is my
problem. I also checked while to see what, if any files needed healing
during the last time this issue occurred using the following command:
gluster volume heal gv0 info
It showed no files in need of healing.
In the log file etc-glusterfs-glusterd.vol.log I see many of the following
entries:
[2014-12-21 19:13:54.137263] W [socket.c:611:__socket_rwv] 0-management:
readv on /var/run/095271447d0b71369a479e6211bbe6e5.socket failed (Invalid
argument)
I have a bricks dir with the file export-brick1.log and it is empty.
gluster volume info as requested:

I also found the following in a log file and perhaps it will help:

With regard to the average number of directory entries, I don't know for
sure but I'm sure some of them get pretty deep.
Finally, I do not have quota enabled.
Again, thank you very much and regards,
