[lustre-discuss] errors 107 in syslog on client 2.8.0

[Ekaterina Popova]

Greetings,

We've installed lustre client 2.8.0 on Debian 8. Lustre is mounted, it 
works, but there are many errors in system logs such as:

Our Lustre servers are not upgraded yet.

uname -s -r
Linux 2.6.32-279.2.1.el6_lustre.gc46c389.x86_64

cat /proc/fs/lustre/version
lustre: 2.1.3
kernel: patchless_client
build:  RC3--PRISTINE-2.6.32-279.2.1.el6_lustre.gc46c389.x86_64

Any help would be appreciated.

Thanks in advance,
