XFS on a 25 TB device
Hello all,
I have just configured a 64-bit CentOS 5.5 machine to support an XFS
filesystem as specified in the subject line. The filesystem will be used to
store an extremely large number of files (in the tens of millions). Due to
its extremely large size, would there be any non-standard XFS
build/configuration options I should consider?
Thanks.
Boris.

generate random numbers subject to constraints
I am trying to generate a set of random numbers that fulfill the following
constraints:
X1 + X2 + X3 + X4 = 1
aX1 + bX2 + cX3 + dX4 = n
where a, b, c, d, and n are known.
Any function to do this?

to make it pass this info to my database server?
Any suggestions would be greatly

Nmblookup trouble
Hi,
Some time ago, I wrote a small script based on some information on one
of the Samba lists, which let me figure out which machine a user was
logged in on. The script was this:-
# smbfind: watch for someone to log in
PATH=/bin:/usr/bin
case $# in
0) echo 'Usage: smbfind <nt_login>' 1>&2; exit 1

Need SAN suggestion
Hello,
It is not total off-topic since almost all connected servers will be RHEL
and CentOS. :)
We are considering to purchase new storage system. The most probably we
will be choosing between HP (EVA6000), EMC (CX3-20C) and Hitachi (similar
model).
iSCSI connection is also required.
What are your experienced with listed systems? What to avoid? What ot
expect?
Now I just know

Hot swap SATA?
Should it be possible to hot-swap SATA drives with Centos5? It doesn't
seem to work on my system. Removing an unmounted drive locked the
system up, and leaving one out at bootup makes the devices change names
and keeps grub from finding /boot on a scsi drive that is shifted up.

Tripp Lite G1000U (0x2007)
Hello,
I'm new to the list, new to NUT, but not new to Unix-likes. I
could use some help getting NUT to talk to my Tripp Lite G1000U.
Searching Google for "Tripp Lite G1000U" returns exactly two hits
at this writing, so that may not be a good sign. ;-) It may just
be rebranded for sale through this source (Costco).
Externally, the G1000U looks much like the SMART1000LCD: an amber

Strange device labeling in 6.3
I have just installed 6.3 on a machine that was previously running
5.8. Under 5.8 eth0 was eth0. Now with 6.3 /sbin/ifconfig gives me lo,
wlan0 and p4p1 (instead of eth0). I would like to make the ethernet a
static IP as I intend to for this to be machine used on my LAN only.
However, when I do /usr/sbin/setup -> Network Configuration the device
is not listed. Can anyone tell me why this is

suggestions for large filesystem server setup (n * 100 TB)
Hi,
over time the requirements and possibilities regarding filesystems
changed for our users.
currently I'm faced with the question:
What might be a good way to provide one big filesystem for a few users
which could also be enlarged; backuping the data is not the question.
Big in that context is up to couple of 100 TB may be.
O.K. I could install one hardware raid with e.g. N big drives

Interpreting data from 220V input APC UPS
Hi --
I am monitoring via the SNMP driver an APC SmartUPS that has split phase
(2L + neutral) 240V input and 120/120 volt outputs. The data for the
voltages is not what I'm expecting, and I am wondering how I should
interpret it. Here is an example from upsc:
input.L1-L2.voltage: 121
input.L2-L3.voltage: 120
input.voltage: 121.20
output.current: 5.90
output.L1-L2.voltage: 119

Interpreting data from 220V input APC UPS
Sounds pretty normal from what I see. It appears that this is *NOT* a true 240v UPS, but rather one that provides two legs of 120v output from two legs of 120 input, and what is seen as "L2" is actually neutral, and the line names are reporting incorrectly. With that in mind, each leg in should be 120v, as well as the outputs, which is exactly what you are seeing.(The fact tht L1 to L3

Failure while upgrading gluster to 3.10.1
Hello Atin,
I've gotten around to this and was able to get upgrade done using 3.7.0
before moving to 3.11. For some reason 3.7.9 wasn't working well.
On 3.11 though I notice that gluster/nfs is really made optional and
nfs-ganesha is being recommended. We have plans to switch to nfs-ganesha
on new clusters but would like to have glusterfs-gnfs on existing clusters
so a seamless upgrade

OT: Measure 2U Server Amp Usage
Hi,
Running a bunch of CentOS servers on 2U supermicro equipment, usually with
8 drives on Adaptec SmartRAID V or LSI Megaraid.
In designing a rack in a data center, the question arises as to how to
measure the amperage the server uses, prior to investing in power drops
that actually do that for you, even remotely, for about $260.00-300USD per
unit. This number is the important one these days

Interpreting data from 220V input APC UPS
Thanks, Tim. The unit was available with single as well as split phase
output, and from the data I can find the input was single phase, though
the input connector has L1/L2/N/G wires. I'm digging through the MIB to
see what the raw data looks like.
Thanks!
John
