Hi List,
Sorry for the crude english !
we have an 3 Nodes gluster Installation.
Since start of this gluster we have problems like this:
[2010-12-10 07:14:57.210627] E [posix.c:437:posix_lookup] posix: lstat
on /backup/mail8-node2/yesteryesterday_root.tgz failed: No data available
[2010-12-10 08:14:57.778585] E [posix.c:1084:posix_mknod] posix: mknod
on /backup/mysql2/yesterday_root.tgz failed: File exists
[2010-12-10 08:14:57.813334] E [posix.c:437:posix_lookup] posix: lstat
on /backup/mysql2/yesterday_root.tgz failed: No data available
I read tons of old maillinglist entry's and some suggest to get the
latest version of glusterfs.
Since 18.11.2010 we have 3.1.0 in use and the errors continues.
Sometimes the problem can be solved for an longer time if unexport and
restart all gluster processes.
I just have no (more) idea were to search for an solution. But I guess
that this should be an trivial Problems since others have obviously
running gluster in production.
The Hardware was selected to be reliable ( Areca Raid6 Drives, Dual Xeon
CPU, Server Mainboards, Server NIC`s) and has continuous data rates if
tested with bonnie.
