SSD and ZFS
Hi all,
just after sending a message to sunmanagers I realized that my question
should rather have gone here. So sunmanagers please excus ethe double

I have inherited a X4140 (8 SAS slots) and have just setup the system

the first two disks

slog tests on read throughput exhaustion (NFS)
I have historically noticed that in ZFS, when ever there is a heavy
writer to a pool via NFS, the reads can held back (basically paused).
An example is a RAID10 pool of 6 disks, whereby a directory of files
including some large 100+MB in size being written can cause other
clients over NFS to pause for seconds (5-30 or so). This on B70 bits.
I''ve gotten used to this behavior over NFS, but

Unbootable system recovery
I have just recently (physically) moved a system with 16 hard drives (for the array) and 1 OS drive; and in doing so, I needed to pull out the 16 drives so that it would be light enough for me to lift.
When I plugged the drives back in, initially, it went into a panic-reboot loop. After doing some digging, I deleted the file /etc/zfs/zpool.cache.
When I try to import the pool using the zpool

are these errors dangerous
Hi everyone,
I''ve been running a zfs fileserver for about a month now (on snv_91) and
it''s all working really well. I''m scrubbing once a week and nothing has
come up as a problem yet.
I''m a little worried as I''ve just noticed these messages in
/var/adm/message and I don''t know if they''re bad or just informational:

I would also like to help as well.
As KMacy knows before i asked a lot of questions for T2 types of
servers but unfortunately i have no more access to those kind of
hardware as well.
I;m willing to participate if a team will be formated.

StorageTek 2540 performance radically changed
Today I updated the firmware on my StorageTek 2540 to the latest
recommended version and am seeing radically difference performance

Solaris 10 U5 with all the latest patches.
This is the performance achieved (on a 32GB file) in February last

Questions about EM algorithm
Dear all:
Assume I have 3 distributions, x1, x2, and x3.
x1 ~ normal(mu1, sd1)
x2 ~ normal(mu2, sd2)
x3 ~ normal(mu3, sd3)
y1 = x1 + x2
y2 = x1 + x3
Now that the data I can observed is only y1 and y2. It is
easy to estimate (mu1+m2), (mu1+mu3), (sd1^2+sd2^2) and
(sd1^2+sd3^2) by EM algorithm since
y1 ~ normal(mu1+mu2, sqrt(sd1^2+sd2^2)) and
y2 ~ normal(mu1+mu3, sqrt(sd1^2+sd3^2))
However, I want

Fitdistr and likelihood
Hi all,
I'm using the function "fitdistr" (library MASS) to fit a distribution to
given data.
What I have to do further, is getting the log-Likelihood-Value from this
estimation.
Is there any simple possibility to realize it?

How does this function print, why is n1 which equals 1 printed as 2?
Windows 7, R 2.12.1
Colleagues,
I am trying to understand the n.for.2means function. The code below is a copy of the function (renamed to n.for.2means.js). I have inserted a single line of code towards the bottom of the function which uses the cat function to print the value of n1. You will note the value (preceded by stars) is printed as 1.
The function (1) prints a lot of output without any

what the problem could be if i am suddenly unable to add abline to the scatter plot?
I am doing very regular stuff like the following:

#fm<- lm(wtana$Body.Wt.on.SD1~wtana$Heart.Wt)
lrf<- loess(Body.Wt.on.SD1~Heart.Wt, wtana)
#lrf<- loess(wtana$Body.Wt.on.SD1~wtana$Heart.Wt)
plot(Body.Wt.on.SD1,Heart.Wt)
#plot(wtana$Body.Wt.on.SD1,wtana$Heart.Wt)

Integration of mixed normal distribution
Hi,
I already found a conversation on the integration of a normal
distribution and two
suggested solutions
(https://stat.ethz.ch/pipermail/r-help/2007-January/124008.html):
1) integrate(dnorm, 0,1, mean = 0, sd = 1.2)
and
2) pnorm(1, mean = 0, sd = 1.2) - pnorm(0, mean = 0, sd = 1.2)
where the pnorm-approach is supposed to be faster and with higher precision.
I want to integrate a mixed

many zeroes in rgamma ... what's going on?
Hello fellow R users,
I wanted to view the density on the standard deviation scale of a gamma(0.001, 0.001) prior for the precision. I did this as seen in the code below and found that for some reason rgamma is giving many values equal to zero, which is strange since a gamma distribution is continuous. What is going on here?
Thanks for any help in advance.

barplot help needed

I would like to create the following barplot:
I have 4 different data sets (same length + stddev for each data point)
data1
sd1
data2
sd2
data3

now, I'd like to plot in the following way:
data1[1],data2[1],data3[1],data4[1] with it's sd-values side-by-side at
one x-axis label (named "position 1") and each bar in different colors.
