CTDB Node unnecessarily banning other nodes
...ther nodes part of CTDB cluster receives the ban message, but even
though the ID does not belong to its CURRENT ID, other nodes bans itself and
goes into recovery mode. I guess this is not supposed to happen?
node2 (should not ban itself):

is 1. Ignoring ban request

[R-pkgs] Probabilistic neural network (PNN)
Dear useRs,
I am pleased to announce the release of the new package PNN.
PNN implements the algorithm proposed by Specht (1990). It is written in the R statistical language. It solves a common problem in automatic learning. Knowing a set of observations described by a vector of quantitative variables, we classify them in a given number of groups. Then, the algorithm i...

[CTDB] how does LMASTER know where the record is stored?
Greetings list,
I was looking at the wiki "samba and clustering" and a ctdb.pdf, admittedly
both are quite old (2006 or 2007) and I don't know how things change over
years, but I just have two questions about LMASTER:
< this is from pdf >
LMASTER fixed
? LMASTER is based on record key only
? LMASTER knows where the record is stored
? new records are stored on LMASTER
