[PATCH 0/5] btrfs: lz4/lz4hc compression
WARNING: This is not compatible with the previous lz4 patchset. If you''re using
experimental compression that isn''t in mainline kernels, be prepared to backup
and restore or decompress before upgrading, and have backups in case it eats
data (which appears not to be a problem any more, but has been during
development).
These patches add lz4 and lz4hc compression

[RFB] add LZ4 compression method to btrfs
Hi,
so here it is, LZ4 compression method inside btrfs. The patchset is based on
top of current Chris'' for-linus + Andi''s snappy implementation + the fixes from
Li Zefan. Passes xfstests and stresstests.
I haven''t measured performance on wide range of hardware or workloads, rather
wanted to publish the patches before I get distracted again. I''d like to ask

Samba 2.2.8 SEGV in rpcclient getdriver on Solaris 7
Hello
I was trying to figure out how to add printer drivers manually for
downloading to Windows 2000 clients and I came accross this problem.
(The printer drivers were installed some time ago using an earlier
version of samba 2.2.x).

[PATCH 1/2] Ocfs2: Add a new code 'OCFS2_INFO_FREEINODE' for o2info ioctl.
The new code is dedicated to calculate free inodes number of all inode_allocs,
then return the info to userpace in terms of an array.
Specially, flag 'OCFS2_INFO_FL_NON_COHERENT', manipulated by '--cluster-coherent'
from userspace, is now going to be involved. setting the flag on means no cluster
coherency considered, usually, userspace tools choose none-coherency strategy by

retrieving large columns using RODBC
Hi,
I have a large table in Postgresql (result of an MCMC simulation, with 1
million rows) and I would like to retrive colums (correspond to variables)
using RODBC. I have a column called "index" which is used to order rows.
Unfortunately, sqlQuery can't return all the values from a column at once
(RODBC complains about lack of memory). So I am using the following code:

Comparison: glm() vs. bigglm()
Hi,
Until now, I thought that the results of glm() and bigglm() would
coincide. Probably a naive assumption?
Anyways, I've been using bigglm() on some datasets I have available.
One of the sets has >15M observations.
I have 3 continuous predictors (A, B, C) and a binary outcome (Y).
And tried the following:
m1 <- bigglm(Y~A+B+C, family=binomial(), data=dataset1, chunksize=10e6)

bigglm Memory Issues
Hi all,
I'm somewhat of a novice in terms of programming, so I thought I'd come here to seek some help with an issue I'm having.
I'm trying to model a glm using bigglm, but in spite of my best efforts, I cannot get it to work!
Here is the particular line of code that is giving me trouble:
>mod = bigglm(Pres/wt ~ Xdes, data=dat, family=poisson(), weights = ~wt, maxit=100,

bigglm "update" with ff
Hi, since bigglm doesn't have update, I was wondering how to achieve
something like (similar to the example in ff package manual using biglm):
first <- TRUE
ffrowapply ({
if (first) {
first <- FALSE
fit <- bigglm(eqn, as.data.frame(bigdata[i1:i2,,drop=FALSE]), chunksize =
10000, family = binomial())
} else {

raid6: rmw writes all the time?
Hi all,
we got a new test system here and I just also tested btrfs raid6 on
that. Write performance is slightly lower than hw-raid (LSI megasas) and
md-raid6, but it probably would be much better than any of these two, if
it wouldn''t read all the during the writes. Is this a known issue? This
is with linux-3.9.2.
Thanks,
Bernd

bigglm binomial negative fitted value
Hi, there
Since glm cannot handle factors very well. I try to use bigglm like this:
logit_model <- bigglm(responser~var1+var2+var3, data, chunksize=1000,
family=binomial(), weights=~trial, sandwich=FALSE)
fitted <- predict(logit_model, data)
only var2 is factor, var1 and var3 are numeric.
I expect fitted should be a vector of value falls in (0,1)
However, I get something like this:

bigglm() results different from glm()
Hi Sir,
Thanks for making package available to us. I am facing few problems if
you can give some hints:
Problem-1:
The model summary and residual deviance matched (in the mail below) but
I didn't understand why AIC is still different.
> AIC(m1)
[1] 532965
> AIC(m1big_longer)

Problem-2:
chunksize argument is there in bigglm but not in biglm, consequently,

Samba Upgrade on Centos 3
After today's samba update, Centos 3 boxes can not use samba to
