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