what you're asking is for mon to tell ipvsadm that the realserver
is not functional when it is. I don't know that it's logically
possible to do this.
That would be the ideal situation, but you are right, this is not
possible. Unless i find a way for mon to check if its suppossed to be
down, even if its working. (that sentence was probably wrong).
So you are right, and I am not counting on mon to tell ipvasdm that the
real server is not functional.
What I am counting on is that you cannot edit a virtual server with
ipvsadm unless that server is allready listed.
So when I manually remove a virtual server (ipvsadm -d). Mon can try to
edit (ipvsadm -e) all it want, but it wont succeed.
Can you assemble your mon.cf file by cat'ing pieces for each
realserver (simulating an include file),
then when you want to remove a realserver, you just comment out
the line that includes the cf data for that realserver?
Iam allready doing this, still it's imperfect:
- It takes me time
- If some virtual servers are down mon will forget there state, and in
some situations they wont be put back in the cluster.
- especially when they recover from there "fail" state before mon
detects it again.
