Re: Ubuntu 9.04 with file issues Cross posted by intent- we're supposed to compare notes on such problems - I hope.
by Jack 10 Sep '10

10 Sep '10

I forgot to mention a few more points. 1) fsck -y isn't designed, at least in single pass mode, to ensure the filesystem is completely fixed (see next point), It is designed to make sure that further writes to the fs don't make it worse, among other things. 2) After running fsck, and it reports, "FILE SYSTEM MODIFIED", you must run fsck again to make sure you don't have further errors. When running fsck it must be run, repeatedly until you no longer get the message above. Only then are all the problems with the fs fixed. 3) If you have in the list of messages a note about hard link count being wrong and the count is too few, you *will* cause the deletion of the file, by using the -y fix. This, on a file that would have been totally recoverable had you not chosen the -y option. 4) In the particular case at hand, where there are multiply linked files, you may also wind up rewriting over the top of a good file with information that is not good, hence causing you to lose a file, had you chosen to not clone the file. The opposite is also true. Lastly, my source for my notes comes from the linux-ext4 mailing list, but what do those guys know anyway? Jack

USB 3.0 Use with Linux
by Peter Cross 26 Aug '10

26 Aug '10

Has anyone tried any USB 3.o devices with any flavor or Linux? I've seen some sites stating that since 2.6.31 usb 3.0 is supported but linux.org/newsstates the following: "The xHCI driver is already included in linux-next and since Linux<http://www.linux.org/news/2009/06/10/0004.html#>2.6.30 has just been released, it should go into the main development tree from which Linux version 2.6.31 will emerge around late August. Users that want to have a look at the new driver can find it in the Git repository." Just wanting to know general experiences if someone has taken the leap... I'm looking at a 2TB external WD drive and am also curious as to which vendor (sabrent, evga, etc) generally has the fewest issues with newer technology. Thanks! Peter -- Cheers! Peter J.

From:torvalds@klaava.Helsinki.FI <From%3Atorvalds(a)klaava.Helsinki.FI> (Linus Benedict Torvalds) Newsgroup: comp.os.minix Subject: What would you like to see most in minix? Summary: small poll for my new operating system Message-ID: 1991Aug25, 20578.9541(a)klaava.Helsinki.FI Date: 25 Aug 91 20:57:08 GMT Organization: University of Helsinki. Hello everybody out there using minix- I'm doing a (free) operating system (just a hobby, won't be big and professional like gnu) for 386(486) AT clones. This has been brewing since april, and is starting to get ready. I'd like any feedback on things people like/dislike in minix; as my OS resembles it somewhat (same physical layout of the file-sytem due to practical reasons)among other things. I've currently ported bash (1.08) an gcc (1.40), and things seem to work. This implies that i'll get something practical within a few months, and I'd like to know what features most people want. Any suggestions are welcome, but I won't promise I'll implement them :-) Linus Torvalds torvalds(a)kruuna.helsinki.fi

Re: [KULUA] How to tell what's stock and what's added in *buntu?

Just finished performing the operation, so I wanted to summarize for everyone. It appears to work great! The only things it missed were stuff that was installed outside the normal workflow, like Picasa. 0) since this is Ubuntu I'm talking about, I'm using my Ubuntu One account as the place to store the work file, so it'll be right there after the install: cd ~/Ubuntu\ One 1) before doing the fresh install: sudo dpkg --get-selections > installed-pkgs.txt 2) perform the installation, and then: cd ~/Ubuntu\ One sudo dpkg --set-selections < installed-pkgs.txt sudo apt-get dselect-upgrade 3) go do something else for a while :-) (actually there were a few packages that required user input to finish) Kendric Beachey On Sat, Aug 7, 2010 at 9:50 AM, Kendric Beachey <kendric.beachey(a)gmail.com>wrote: > I'm preparing to actually do this now...just to see what that grep catches > I tried it reversed: > > ak@mfj:~$ sudo dpkg --get-selections | grep -i kernel > kerneloops-daemon install > nfs-kernel-server install > nvidia-173-kernel-source install > nvidia-kernel-common deinstall > vmware-player-kernel-modules-2.6.17-11 deinstall > vmware-player-kernel-modules-2.6.20-15 deinstall > vmware-player-kernel-modules-2.6.20-16 deinstall > ak@mfj:~$ > > Given that most of this isn't the kernel itself I'm going to leave these > things in.

Cool, this looks even better. But just to make sure I understand, where does the new required step go in relation to the other two? Kendric Beachey On Wed, Aug 4, 2010 at 6:52 PM, Christofer C.

Awesome, that's probably what I will go with, thanks Paul! (rather than doing something with R, I will probably just diff the two files and see about scripting something with the result.)

How to tell what's stock and what's added in *buntu?
by Kendric Beachey 04 Aug '10

My daughter's Edubuntu machine had some slight issues during the upgrade from 9.10 to 10.04. It was alllllmost done with the upgrade (percentage in the upper 90s) when it locked up hard and all I could do was reset it. I thought maybe I'd have to do the upgrade over but from that point on it has operated as a 10.04 machine. That was early May. Everything seems to work for the most part, although while booting up and shutting down, it has a text-based screen instead of the graphical one. Also the sound has some real hiccups, at least during login, and it's been having some stone cold lockups lately, especially while doing lengthy network-intensive operations. I could try to fix it as it stands, but at this point I'd rather do a fresh install. I've got the Edubuntu 10.04 dvd on the desk, and /home is on its own partition, so the data there will survive and I'll just have to recreate the user accounts. The thing I would like to do is get a list of the various pieces of software I've installed over and above the stock selection that ships with Edubuntu, so I can reduce the time spent redoing all that installation work. Does anyone know of a good way to get the system to tell you a list of all the .debs you have installed beyond what it shipped with? Thanks! Kendric Beachey
