Data recovery emergency on a downed server... Help please!!

Hi everyone, Well, the fact that I am posting this after 12:00am Sunday night (and on my birthday, to-boot!) should indicate just how dire the situation is... I have had a drive failure on a server and I can no longer mount the data partition on the hard drive (/dev/hda5 [ext3 under RH7.3]) because the replacement server (Fedora Core 1) claims that the drive's superblock is toast. Now, before anyone rips me a new one, I -DO- have a tape drive but that, too, has rather depressingly failed. When I try to recover the files from the IDE Travan 8GB drive it successdully recovers about 50 files and then fails with this... -= Begin Error =- [root-9CO/sRhIDOA at public.gmane.org tape]# tar zxvf /dev/ht0 . [bunch-of-files] . home/OldC/Program Files/Common Files/Symantec Shared/VirusDefs/19970902.001/navex15.exp home/OldC/Program Files/Common Files/Symantec Shared/VirusDefs/19970902.001/navex15.sys home/OldC/Program Files/Common Files/Symantec Shared/VirusDefs/19970902.001/NAVEX15.VXD gzip: stdin: unexpected end of file tar: Unexpected EOF in archive tar: Unexpected EOF in archive tar: Error is not recoverable: exiting now [root-9CO/sRhIDOA at public.gmane.org tape]# -= End Error =- This is true on three of the tapes I have tried to recover from. The data was backed up via this simple script: -= Begin Script =- mt -f /dev/ht0 erase mt -f /dev/ht0 rewind tar zcvf /dev/ht0 /home/* -= End Script =- I have been Googling for a while now with no success. If anyone has any clues, by all means -please- share them... Also, if anyone here can recommend (as a fall back) a data recovery house that won't balk at an ext3 partition, please forward contact info. Thanks everyone (again!!!)

I don't have a problem with anything you're saying, except that I miss the point. I certainly wouldn't be happy doing software development with 64MB on any of my systems, whether Linux, Mac, or MS. I have a Dell P3 733 that was given to me with NT 4 Workstation running. I have it dual-booting with NT and SuSE 8.1/KDE. The interface feels faster under Linux than Windows. Years ago -- when NT 4 was new -- I converted a PII to Linux and used it as an Internet gateway for a 20-person office. Running NT, it wouldn't have worked as well...if at all. Since the people referenced in the above quote are using NT already, then equivalent functions on a Linux system should *not* be a *worse* experience for performance. I think one would have to try really hard to install Linux such that it felt slower than NT on any given system. If workers need upgraded systems because of their job functions or because the standard for acceptable performance has changed, that's fine. If they need them just to do an XP upgrade -- like the article suggests -- that seems terribly wasteful. ........................

Kernel 2.6 compile: Comaptability

Good advice, although I had my own way with it, and it works fine. Now to work out the module problem. I still haven't updated /etc/modules.conf Thanks for the advice so far.

Years would not be enough to accomplish this. ;-) I meant for you to activate whatever your system uses for indexing program and let it run (can take two days). It could be glimpse or htdig. I use htdig. Then you have a search form which you access locally with your browser and can do text searches on your own system. Obviously this includes infos, howtos, and most documents you have on your system. I have almost 2GB indexed and I can find everything (eventually). hope this helps, Peter -- The Toronto Linux Users Group.
