I have just set up stream pass through using ssl_preread in nginx, but I can't for the life of me figure out how to, using this method, ban access to specific upstream servers for certain ip ranges.
Such that host1 should not allow 10.0.1.0/24 for example and host2 should not allow 10.0.44.0/24
I have set up regular scrub on my ZFS pools and am beginning to look at setting up smart check every now and then, but I have a distinct memory of an entry I am unable to find that one should not schedule overlapping times. Is there any such considerations one should take into account when it comes to scheduling, for example scrubs, resilvering and smart checks? scrubs and resilvering seem obvious, but between other disk maintenance operations? While I read some talking of not overlapping scrubs on multiple pools, should one consider it when running a smart check on an raid array and a scrub on an pool in the same system?
