we have backup server with rhel version 7.2
server is VM machine , and OS disk is VMDK disk
disk used space is around - 50% , and from smartctl we not see problem
as we can see from follwing details
the disk util is very high sometimes even reached 100%
we can see also high pressure from reading side
regarding the util values , we think disk cant be helthy for a long time when util is around 90%-100%
but apprititae to get your feedbacks / notification about this
