This is a characteristic of SVM. Why are you trying so many things at one go? You should be isolating one prob at a time. SVM does not provide hot-plug feature. If you want that, go for H/W raid. You cant simply pull out the other disk and expect to boot from the other just because its mirrored. Please review raid 1 concepts.

Reason: edit "Get the concept of mirroring right" as its harsh.

svmocas
SVMOCAS(1) General Commands Manual SVMOCAS(1)
NAME
svmocas - train a binary linear SVM classifier
SYNOPSIS
svmocas [options] example_file model_file
DESCRIPTION
svmocas is a program that trains a binary linear SVM classifier using the Optimized Cutting Plane Algorithm for Support Vector Machines
(OCAS) and produces a model file.
example_file is a file with training examples in SVM^light format, and model_file is the file in which to store the learned linear rule
f(x)=w'*x+w0. model_file contains d lines, where d is the number of data dimensions. The first n lines are coordinates of w and the last
line is w0.
OPTIONS
A summary of options is included below.
General options:
-h Show summary of options.
-v (0|1)
Set the verbosity level (default: 1)
Learning options:
-c float
Regularization constant C. (default: 1)
-C constants_file
If specified, each example has a different regularization constant, taken from the text file constants_file. Each line of the text
file must contain a single constant (positive double) for the corresponding example. If -C is used, then the -c option is ignored.
-b (0|1)
Value of the L2-bias feature. A value of 0 implies not having bias. (default: 0)
-n integer
Use only the first integer examples for training. By default, integer equals the number of examples in example_file.
Optimization options:
-m (0|1)
Solver to be used:
0 ... standard cutting plane (equivalent to BMRM, SVM^perf)
1 ... OCAS (default)
-s integer
Cache size for cutting planes. (default: 2000)
-p integer
Number of threads. (default: 1)
Stopping conditions:
-a float
Absolute tolerance TolAbs: halt if QP-QD <= TolAbs. (default: 0)
-r float
Relative tolerance TolAbs: halt if QP-QD <= abs(QP)*TolRel. (default: 0.01)
-q float
Desired objective value QPValue: halt is QP <= QPValue. (default: 0)
-t float
Halts if the solver time (loading time is not counted) exceeds the time given in seconds. (default: infinity)
EXAMPLES
Train the binary SVM classifier from riply_trn.light, with the regularization constant C=10, bias switched on, verbosity switched off, and
save model to svmocas.model:
svmocas -c 10 -b 1 -v 0 riply_trn.light svmocas.model
Compute the testing error of the classifier stored in svmocas.model with linclass(1) using testing examples from riply_tst.light and save
the predicted labels to riply_tst.pred:
linclass -e -o riply_tst.pred riply_tst.light svmocas.model
