Panics with md/gvinum/ufs
Hi,
I've done some strange(?) experiments and I managed to get
a panic of type "baddir" and just now another one that only
rebooted my system instantly without writing a vmcore.
I don't know if this is important. I could not find any
information on how gvinum detects failed hard disks.
That's why I tried something really simple.
Steps to reproduce:
1)
dd if=/dev/zero of=a

heatmap with levelplot
Hi there,
I'd like to create a heatmap from my matrix with
a) a defined color range (lets say from yellow to red)
b) using striking colors above and below a certain threshold (above = "green",
below = "blue")
Example matrix (there should be a few outliers generated...) + simple levelplot
without outliers marked:
library(lattice)
my.mat <- matrix(rnorm(800), nrow =

Kernel Panic
I have just installed Redhat 7.2 on a P3 with adaptec 2400A IDE RAID. After
many attempts with the partitions, I have finally managed to install but not
get the following error on boot:

Dataframe calculations
Hi everyone,
My question will probably seem simple to most of you, but I
have spent many hours trying to solve it. I need to perform
a series of sequential calculations on my dataframe that move
across rows and down columns, and then repeat themselves at
each unique 'MM' by 'DD' grouping. Specifically, I want to add
'DEPART' time (24 hr time) to 'TRAVEL'(minutes)

Gluster native mount is really slow compared to nfs
Hello Joe,
?
?
I really appreciate your feedback, but I already tried the opcache stuff (to not valildate at all). It improves of course then, but not completely somehow. Still quite slow.
?
I did not try the mount options yet, but I will now!
?
?
With nfs (doesnt matter much built-in version 3 or ganesha version 4) I can even host the site perfectly fast without these extreme opcache settings.

Gluster native mount is really slow compared to nfs
Hi all,
?
?
One more thing, we have 3 apps servers with the gluster on it, replicated on 3 different gluster nodes. (So the gluster nodes are app servers at the same time). We could actually almost work locally if we wouldn't need to have the same files on the 3 nodes and redundancy :)
?
Initial cluster was created like this:
?
gluster volume create www replica 3 transport tcp

Gluster native mount is really slow compared to nfs
Hello Vijay,
?
?
What do you mean exactly? What info is missing?
?
PS: I already found out that for this particular test all the difference is made by :?negative-timeout=600 , when removing it, it's much much slower again.
?
?

Gluster native mount is really slow compared to nfs
Hello,
?
?
Here is some speedtest with a new setup we just made with gluster 3.10, there are no other differences, except glusterfs versus nfs. The nfs is about 80 times faster:

Gluster native mount is really slow compared to nfs
My standard response to someone needing filesystem performance for www
traffic is generally, "you're doing it wrong".
https://joejulian.name/blog/optimizing-web-performance-with-glusterfs/
That said, you might also look at these mount options:
attribute-timeout, entry-timeout, negative-timeout (set to some large
amount of time), and fopen-keep-cache.

Confusing lstat() performance
Hi,
I have a gluster 3.10 volume with a dir with ~1 million small files in
them, say mounted at /mnt/dir with FUSE, and I'm observing something weird:
When I list and stat them all using rsync, then the lstat() calls that
rsync does are incredibly fast (23 microseconds per call on average,
definitely faster than a network roundtrip between my 3-machine bricks
connected via Ethernet).
But

overview of patches used in Fedora
Hi,
I have gone through the patches that are used in the Fedora package and
probably only the "mkcert-permissions" [1] can be considered to be
included upstream. It is dated into package version 1.0-0.beta2.3, but I
cannot find any particular reason for the inclusion (like a bug in
bugzilla, etc.). Some (winbind support, quota warnings) were obsoleted
by dovecot 1.1, two are used for

Creating dataframe of all possible variable combinations
Hello,
I need to create a dataframe containing all possible combinations of three variables: SITE (101,102,103,104), WDAY (MON,TUE,WED,THR,FRI), and TOD (MORN, AFTN). There should be a total of 40 unique combinations in my dataframe. I used expand.grid() successfully(?) to create my dataframe, but then when I went to order it by SITE, the resultant dataframe only contained four rows, one for each

multiple cores?
A question that someone asked me, cut and pasted from another board:
>>I've got 8 cores on my machine and while encoding only one processor is used,
and maxed out. Is there any way to distribute the load across multi-cores?<<
I have no idea what the answer to this is. The question was about flac on OS X
