daylight saving / time zone issues with as.POSIXlt/as.POSIXct (PR#10392)
Running under Windows XP 64 bit, as.POSIXlt()/as.POSIXct() seem
to think that US time zones (EST5EDT, MST7MDT) switched from daylight
savings back to standard time on Oct 28, 2007, whereas the switch
is actually on Sun Nov 04, 2007.
Examples:
> Sys.timezone()
[1] "Mountain Daylight Time"
> as.POSIXct("2007-10-30 12:38:47")
[1] "2007-10-30 12:38:47 Mountain

DateTime Math in R - POSIXct
Greetings -
I'm battling POSIXct, as per the code below. My input is actually an XL
file, but the weird results below correctly model what I am seeing in my
program.
Before I punt and use lubridate or timeDate, could anyone please help me
understand why POSIXct forces my variable back to GMT?
I suspect that I'm not properly coding the tzone value, but it does not

DST and VM timestamp
Who is tired of dealing with DST changes?
I have asterisk running on FC4, FC4 has been patched and shows the
correct MDT timezone and time.
Email notifications of voicemail show the message time an hour early
(standard time, not daylight). This si the time in the message body, not
the email delivery time, so it is coming form asterisk wrong.

timezone conversion difficulties with the new US daylight saving time switch over
I'm having difficulties with daylight saving times in US time zones.
(Apologies for the long post, but the problem seems subtle and complex,
unless I'm doing something completely wrong, in which case it should
be evident from the first 10 lines below.)
This is what I see, using a (slightly modified) example from ?as.POSIXlt :

Tasks get executed twice with repeat_every
I have a simple worker that I set up with repeat_every:

@logger.debug("Sending due notes. The current time is #{Time.now}")

I want this to run every minute, all the time. The first run is fine,

maximum MDT inode count
For future filesystem compatibility, we are wondering if there are any
Lustre MDT filesystems in existence that have 2B or more total inodes?
This is fairly unlikely, because it would require an MDT filesystem
that is > 8TB in size (which isn''t even supported yet) and/or has been
formatted with specific options to increase the total number of inodes.

I''m evaluating lustre. I''m trying what I think is a basic/simple
ethernet config. with MDT and OST on the same node. Can someone tell
me if the following (~150 second recovery occurring when small 190 GB
OST is re-mounted) is expected behavior or if I''m missing something?
I thought I would send this and continue with the eval while awaiting

Convert numeric value to POSIXct
Hi,
How do I convert a numeric value indicating the time since 1970, back into
a POSIXct class object? I have tried format.POSIXct and as.POSIXct
without success.
For example

> ddd<- as.numeric(ccc);
> ddd
[1] -788842800

pxechn.c32: passing options to iPXE
In PXELinux 4.06 (the vanilla version, not gpxelinux.0), I'm trying to use
pxechn.c32 to call iPXE (undionly) with option 67 set to call an iPXE
script.
The relevant portion of my PXELinux config looks like this:

MENU LABEL ^B - MDT 2012 SP1

APPEND undionly.kpxe -o 67.s=ipxe/mdt.ipxe
However iPXE doesn't seem to get the option correctly, it goes into

SSD caching of MDT
Article by Jeff Layton:
http://www.linux-mag.com/id/7839
anyone have views on whether this sort of caching would be useful for
the MDT? My feeling is that MDT reads are probably pretty random but
writes might benefit...?

Dedicated MGS?
This may be in the documentation. If so, I missed it.
If a site has multiple Lustre file systems, the documentation implies
that there only needs to be a single MGS for an entire site
(regardless of the number of file systems). However, I also know
it is fairly common to have a combined MGS/MDT. So here are the
questions.
1. If we are going to have several Lustre file systems,
