We are using couchbase 3.0 and have around 67 GB free disk space, which is 35% free. But we face this warning this morning from the tab "Cluster Overview" in couchbase's admin page:
Approaching full disk warning. Usage of disk "/" on node "local.node" is around 100%
Even the admin page shows the correct Disk Overview: Usable Free Space (67.9 GB). But how come this warning appears?
