Hello,<br>
we have big problem with metadata IO error and swap issue <br>
with: <br>
OS = RHEL - 7 - 1.1503.el7.centos.2.8<br>
kernel = 3.10.0 - 229.4.2.el7.x86_64<br>
KVM Version = 2.1.2 - 23.el7_1.3.1<br>
LIBVIRT = libvirt-1.2.8-16.el7_1.3<br>
gluster = glusterfs-3.7.1-1.el7 ( replica 2 on
XFS )<br>
Phys.MEM = 128667 MB total, 23160 MB used, 105507 MB free<br>
swap = 398334 MB total, 32049 MB used, 366285 MB
free<br>
<br>
Can anybody get any idea what's wrong ??<br>
System swapping continualy in spite of a lot of free memory
available. ( we added large temporary swap space )<br>
<br>
