Rescuing Data From a Hard Drive

by Michael Zarozinski

Hi All, I've got a bit of a problem... we have a linux server that contained 2 hard drives. The one with the boot information died - LUCKILY the data we NEED was on the hard drive that lived. My question is... how can I recover the data I need? I've been able to boot to the shell using the install disk and can see the data I need but that shell doesn't provide access to the network card so I can copy the data off. I tried a fresh install on a new HD but when I attatch the 2nd HD (with the data I need) I can't see it. Forgive me, I come from the windows world where just plugging in the old HD would allow me to pull the data off. Any ideas/help/etc is greatly appreciated! Michael Z

Yep, I'm pretty sure that was the graphical installer. Normally, for a stage1 install there is a 60M cd image that boots and has only command-line, but has many drivers that would be needed for a wide range of system installs. This method has an install guide of 7-8 webpages (the handbook) that walk you through everything from installing the basic packages to building a kernel and then setting up grub. The only complicated part is setting the CFLAGS and USE variables. -Jared On 1/31/06, Mike Leo <mleo963(a)yahoo.com> wrote: > I did not try ( or know of) a graphical installer... > > i booted off the "livecd" and walked through the handbook to install....then gave up... > > thanks for the feedback anyway. > > --- Greg Labonte <gbonte(a)WPI.EDU> wrote: > > > Just wondering Mike, Did you try using the Graphical installer for > > Gentoo? > > > > > > > On 1/30/06, Mike Leo <mleo963(a)yahoo.com> wrote: > > >> Am I wrong, or is the gentoo install insanely comlicated? > > >> > > >> Although I did not sit in front of it from start to finish, it > > >> seems like an install takes hours > > >> and hours of work... > > >> > > >> I followed the Handbook (some 80 pages of documentation), which > > >> i'm sure is very accurate and each > > >> step worked as advertised, but in the end it was too much. > > >> > > >> After an install of debian, which takes me less than 20 minutes, > > >> this was too much for my poor > > >> little brain to take, and I eventually gave up. > > >> > > >> In addition to that, I can't for the life of me, get slackware to > > >> consistantly install lilo > > >> correctly during the install. > > >> > > >> Any comments on either of these would be apreciated, however, I am > > >> just writing this to toss my > > >> vote in for a linux install fest as a meeting topic. > > >> > > >> I have no problem bringing in a laptop to show the simple, > > >> eligant, streamlined, 20 minute debian > > >> install, but I would like to also see someone go through a gentoo > > >> install, and assist on a > > >> slackware lilo config...all of which can be done via my laptop if > > >> needed. > > >> > > >> Thanks ! > > >> Mike > > >> _______________________________________________ > > >> Wlug mailing list > > >> Wlug(a)mail.wlug.org > > >> http://mail.wlug.org/mailman/listinfo/wlug > > >> > > > > > > _______________________________________________ > > > Wlug mailing list > > > Wlug(a)mail.wlug.org > > > http://mail.wlug.org/mailman/listinfo/wlug > > > > _______________________________________________ > > Wlug mailing list > > Wlug(a)mail.wlug.org > > http://mail.wlug.org/mailman/listinfo/wlug > > > > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug >

I did not try ( or know of) a graphical installer... i booted off the "livecd" and walked through the handbook to install....then gave up... thanks for the feedback anyway. --- Greg Labonte <gbonte(a)WPI.EDU> wrote: > Just wondering Mike, Did you try using the Graphical installer for > Gentoo? > > > > On 1/30/06, Mike Leo <mleo963(a)yahoo.com> wrote: > >> Am I wrong, or is the gentoo install insanely comlicated? > >> > >> Although I did not sit in front of it from start to finish, it > >> seems like an install takes hours > >> and hours of work... > >> > >> I followed the Handbook (some 80 pages of documentation), which > >> i'm sure is very accurate and each > >> step worked as advertised, but in the end it was too much. > >> > >> After an install of debian, which takes me less than 20 minutes, > >> this was too much for my poor > >> little brain to take, and I eventually gave up. > >> > >> In addition to that, I can't for the life of me, get slackware to > >> consistantly install lilo > >> correctly during the install. > >> > >> Any comments on either of these would be apreciated, however, I am > >> just writing this to toss my > >> vote in for a linux install fest as a meeting topic. > >> > >> I have no problem bringing in a laptop to show the simple, > >> eligant, streamlined, 20 minute debian > >> install, but I would like to also see someone go through a gentoo > >> install, and assist on a > >> slackware lilo config...all of which can be done via my laptop if > >> needed. > >> > >> Thanks ! > >> Mike > >> _______________________________________________ > >> Wlug mailing list > >> Wlug(a)mail.wlug.org > >> http://mail.wlug.org/mailman/listinfo/wlug > >> > > > > _______________________________________________ > > Wlug mailing list > > Wlug(a)mail.wlug.org > > http://mail.wlug.org/mailman/listinfo/wlug > > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug >

You can get up to 1/8192Hz (122us) periodic interrupts with the x86 RTC timer. You might have to do a little setup, like, # modprobe rtc # echo 8192 > /proc/sys/dev/rtc/max-user-freq [ fiddle permissions on /dev/misc/rtc or /dev/rtc unless you are running your app as root ] See Documentation/rtc.txt in the kernel source for programming details. Basically the kernel is free to idle or run other things until the RTC interrupt hits, then it wakes up your app doing read() or poll() on /dev/rtc. I used this to pulse a hardware register in a project I did a few years ago, worked good enough for my purposes. You might lose an RTC interrupt here and there if your system is under heavy load (call it "soft realtime"), but I think the interface tells you if and how many you lost. There's also the more advanced HPET timer available for newer x86 systems, but I haven't looked at that yet. Good luck, -Jamie Guinan

I tried it when it came out and it didn't really seem to simplify installation at all. It was just a graphical representation of the actions normally performed on the command-line. Has it changed since then? -Jared On 1/30/06, Colin Wilson <cwilson(a)wpi.edu> wrote: > I have used the graphical gentoo install a few times, the last time I > looked at it it was still in Beta and it did not work perfectly.

I have used the graphical gentoo install a few times, the last time I looked at it it was still in Beta and it did not work perfectly. That might have changed at this point, but I doubt that because it was more of a small side project than anything else. -- Colin Wilson Secretary WPI Cycling www.wpi.edu/~cwilson 617.899.1242

Re: [Wlug] meeting topic

I have Gentoo on my notebook and it works great! I especially like the fact that the package that has my wireless card in it (orinoco_usb) was written so that it will automatically download the cvs HEAD and build that so I get the most up to date driver. I've had this installed for about a year and it only took about a day to install it, but that was mostly due to the fact that I choose the stage1 install, which isn't the main documented installation method anymore (stage3 is now). Its not that its hours and hours of work - its more like a little research up front and a hours of entering data in here and there (at least in my experience). If you're going for ease of install and use I would def have to throw my hat in the ubuntu ring. Kubuntu is about the easiest install I've seen. -Jared On 1/30/06, Mike Leo <mleo963(a)yahoo.com> wrote: > Am I wrong, or is the gentoo install insanely comlicated? > > Although I did not sit in front of it from start to finish, it seems like an install takes hours > and hours of work... > > I followed the Handbook (some 80 pages of documentation), which i'm sure is very accurate and each > step worked as advertised, but in the end it was too much. > > After an install of debian, which takes me less than 20 minutes, this was too much for my poor > little brain to take, and I eventually gave up. > > In addition to that, I can't for the life of me, get slackware to consistantly install lilo > correctly during the install. > > Any comments on either of these would be apreciated, however, I am just writing this to toss my > vote in for a linux install fest as a meeting topic. > > I have no problem bringing in a laptop to show the simple, eligant, streamlined, 20 minute debian > install, but I would like to also see someone go through a gentoo install, and assist on a > slackware lilo config...all of which can be done via my laptop if needed. > > Thanks ! > Mike > _______________________________________________ > Wlug mailing list > Wlug(a)mail.wlug.org > http://mail.wlug.org/mailman/listinfo/wlug >
