LVM documentation and/or basic help wanted
by Chris G 13 Oct '07

13 Oct '07

My system has two physical disks. When I installed Fedora 7 I gave it one of the two disks all to itself (having copied the data I wanted elsewhere). Fedora 7 uses LVM2 to manage its disks. Now the installation seems to be well sorted and stable I'd like to use LVM for the other disk as well, it's currently partitioned the 'old fashioned' way. I can (hopefully!) manage the issues of saving the data on the old disk before splatting it with LVM but I need some guidance on the best ways to use LVM - i.e. how to split up the disk etc. Currently Fedora has made the one physical disk it has into one Physical Volume and has assigned it all to one Volume Group. Presumably I'll make the other disk (when empty) into a second Physical Volume. But then I wonder what to do next. Should I add the new Physical Volume to the existing Volume Group or would I be better off adding a new Volume Group? What are the pros and cons of the two approaches? Then should I split the Volume Group into more than the two logical volumes it has at the moment? Currently it's just a huge / and a 2Gb swap. /home is on the 'old' disk at present. Would I be better putting at least /home into a separate Logical Volume (I think the answer to that is 'yes')? Currently /etc/fstab is as follows:- /dev/VolGroup00/LogVol00 / ext3 defaults 1 1 LABEL=/boot /boot ext3 defaults 1 2 tmpfs /dev/shm tmpfs defaults 0 0 devpts /dev/pts devpts gid=5,mode=620 0 0 sysfs /sys sysfs defaults 0 0 proc /proc proc defaults 0 0 /dev/sda1 /slackroot ext3 defaults 1 2 /dev/sda3 /home ext3 defaults 1 2 /dev/sda4 /scratch ext3 defaults 1 2 /dev/VolGroup00/LogVol01 swap swap defaults 0 0 /dev/sda5 swap swap defaults 0 0 One other issue that occurs to me is that there must (I guess) be something on /dev/sda that tells grub that /boot is /dev/sdb1 and I'm a bit worried that this might get splatted and stop the system booting. Or is the boot block sacrosanct from lvm/fdisk etc.? I can understand the basics of LVM, i.e. how to do things, but it would be useful to have a 'why' document. -- Chris Green

Hi all, Thought I'd join your mailing list in the hope to advance my knowledge of Linux. I'm fairly new to Linux and I'm totally fed up with Windoze. I use Fedora and have found it quite a good learning curve. I also hope to come along on thursday evening. Neil

Open Office and Word
by Bev Nicolson 10 Oct '07

10 Oct '07

I sent a document to someone recently and their machine kept crashing when they tried to put changes into it. (They use MS.) I've not had this problem before and I'm wondering exactly how compatible Open Office and Word are. What's your experience?

Preventing ouput mail from shell script
by Jenny Hopkins 10 Oct '07

10 Oct '07

Hullo there, I'm trying to prevent a very simple script in cron.hourly from sending mail when it executes. The script consists of mount -a > /dev/null I hoped the output would be directed to a black hole, but it sends a mail every hour as below. /etc/cron.hourly/checkmounts: mount: knossos:/home already mounted or /nfshome busy mount: xios:/home already mounted or /nfshome-xios busy run-parts: /etc/cron.hourly/checkmounts exited with return code 32 Is the only way to prevent mail output to make the script more complicated with exit codes and whatnot? Thanks, Jenny

Googling turns up > http://www.python.org/doc/current/lib/cgi-intro.html which suggests > that the header is output explicitly ('print "Content-Type: > text/html"'). I use pyblosxom too and the issue there is that it's not just the one script for me; it's a whole series of python files and the content-type header is outputted in a dynamic way, i.e. there's no obvious place you can add in the encoding to the end of the header line. I tested with wget and my installation also seems to be sending charset=UTF-8 despite the pyblosxom config saying py["blog_encoding"] = "iso-8859-1". Either pyblosxom is ignoring it or it's not sending one at all and Apache is jumping in with the default charset. Perhaps pyblosxom needs some hacking to send the right headers. I tried to run it from the command line, but the script is too clever: when it runs from the command line, it goes into an "installation verification system" where it checks it's installed correctly. It only outputs HTML when run as a cgi from what I can tell. Ross

Why does Firefox always use UTF-8 for this page?
by Chris G 10 Oct '07

10 Oct '07

I have a web page which has a couple of special characters which are ISO-8859-1 encoded, 'View Source' shows that the header is as follows:- <head> <title>Chris Info</title> <link rel="stylesheet" href="http://home.isbd.net/css/infowiki.css" type="text/css"> <link rel="alternate" type="application/xml" title="RSS" href="/blog/rss2.xml"> <link rel="top" href="/" title="pyblosxom.sourceforge.net"> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1"> </head> ... but when started up Firefox always sets the character encoding to "Unicode (UTF-8)" by default and to see the characters correctly I have to manually switch it to "Western (ISO-8859-1)". Is Firefox subtly trying to push me in the 'right' direction or, more realistically, what am I doing wrong? I have tried setting things to default to ISO-8859-1 in Firefox but I don't seem to be getting anywhere. -- Chris Green

Which are you trying to specify here? <Directory> is for filesystem locations, otherwise you want <Location>. As has been said, if it's a request to a CGI script you can set the headers in the script. You should probably do it that way if possible, because I'm sure headers set by CGI trump Apache's default Charset and I suspect also the specific sets. You may find that the script already sets a charset (CGI scripts are required to provide a Content-type: header, I think). Matthew

Inserting a file into a telnet session
by ted.harding＠nessie.mcc.ac.uk 09 Oct '07

09 Oct '07

Hi Folks, Maybe someone knows how to so this! Say I'm logged in to a remote host in a telnet session. At a certain point, I would like to send the contents of a text file to the other end (as if I'd typed them in by hand). OK, in principle I could do this by opening the file in another xterm, and using the mouse to paste the lines into my telnet session. But in this instance I don't want to do that. What I'd really like to do is to be able to "break out" of the direct connection between my keyboard and the far end, and issue a local command to squirt said file down the line via the telnet session. And then break back in again. There doesn't seem to be any method of doing this with normal telnet (as far as I can make out from 'man telnet'). Any suggestions? (After all, one used to be able to do this kind of thing with kermit, when on dial-up via a serial port!) With thanks, and best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <ted.harding(a)nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 08-Oct-07 Time: 18:09:37 ------------------------------ XFMail ------------------------------
