Why is that? I would have expected more usable space to reduce the need for fragmentation. I routinely use 0 on non-system filesystems. I read this often, and to me it seems to make sense. When a file system is nearly full, writing a last big file will make the file being cluttered along all those tiny places where some free space is still left. And this probably already happens to some extent before the filesystem is completely full. Now, which values for reserved percentage are good, I don't know. The 5% figure is completely arbitrary and dates back many years. There was no good reason then for it to be exactly 5%, it just happened to mostly work fine. Remember that was a time when 250M was a BIG drive. 5% is 2.5K and that is about the size of the largest single file people realistically were using. So 5% wiggle room for root lets you manipulate the last single file you were using when the drive filled up, and hence save the day. These days 2TB file systems are common and 5% means 20G. How many 20G files do you routinely have on a single file system? Media drives aside, a few meg is still about the broad average file size. It is just not realistic to reserve emergency wiggle room for root that amounts to 20,000 average files. It means there's no single sane default anymore. On my servers I set reserved space to 100M or so as that's what I need. I reckon the average person should keep it to somewhat larger than the biggest single file you expect to store on that file system. This probably depends much on the typical size of files on that partition, and usage patterns. For large movies on your data partition, it probably does not matter, but for my system partitions (/root, /usr, /var, /tmp, portage stuff) I just keep it at 5%. With the benefit that I can instantly free some space in /var when it's just become full, without needing to decide what to delete. Okay, in practice this does not matter much because resizing the LVM and resizing the FS is also a matter of seconds only. Wonko -- Alan McKinnnon alan.mckin...@gmail.com

Now, when I try /etc/init.d/net.wlan0 start the screen gets blanked on a console as well as from an XTerm and the kernel crashes totally, i.e. the emergency reboot doesn't work either. And trying to do an strace with output to a file shows that even this output file doesn't exist (i.e. hasn't been closed) So, what can I try next? Many thanks for a hint, Helmut.

Believe me, this is very annoying when copying/moving many files around. And don't press del to delete the files you copied, you might put all files in that directory to the trash. The scrolling behaviour was also annoying, I drag a file to the destination folder, which is near the top, and just when I release, the folder started to scroll away and the file is moved into another folder. Both bugs seem to be fixed in 4.8, and now Dolphin is better than the Windows XP explorer, finally. Of course, there was another bug introduced, couldn't reproduce it yet, and it does not happen often. All stuff scrolls down to the bottom then, I cannot scroll up, but with wild clicking on all mouse buttons it finally stops. Another example of these weird problems, just because it happened today: I copied 100 MB via FTP using Dolphin. Then I got an error dialog, there was a problem writing the file. Dolphin did not update the content, so I could not see how far the upload went. After some F5 pressing, it said internal error, please send a detailed bug report. Seems there was a problem renaming the file after download, I had to remove the '.part' suffix manually. No big deal, but such problems happen all over the time when I use KDE applications. Some errors are reproduceable, and I can avoid them, but many things just happen once. If you are an experienced user, you can live with that - as I said, I still like KDE, and its great features. But for the inexperienced user like my mom KDE is totally unusable, as very basic features often do not work. Like, logging out.

At this moment you don't know what caused the corruption - it could well be a warning of worse things to come as far as this drive is concerned ... ;-) It is much better if you create the image with dd-rescue/ddrescue (can't recall which of the two packages is claimed to be better). You may also want to make a backup copy of the image in case you embark on any destructive operations on it. Multiple passes with ddrescue may recover more bits/bytes so hopefully you'll have a more complete set of data to work with. With PhotoRec, I can recover parts of the MySQL Database but I cannot get the important *.MYD files because I guess PhotoRec doesn't have the signatures for that type of file. So, any options I have at this point? You can use dd or hexdump to pick up some blocks at the start of a known good *.MYD file, create a signature for PhotoRec and add it on the list of files to check for. See the instruction of how to go about this here: http://www.cgsecurity.org/wiki/Add_your_own_extension_to_PhotoRec -- Regards, Mick Never had a chance to reply back but this was very helpful. Now to search online to see if people created signatures for IBD files (where the actual data for a MySQL database lives) as the headers are different for every sample IBD I tried from working databases.

[gentoo-user] Somewhat OT - Grandtech PC to TV component and X
I recently bought a new Gradtec PC To TV component because my old Grand Pro Ultimate XP that I bought in 2004 was on its last legs. We used the Ultimate XP so that we could use the living room TV as a monitor, so that we could watch MythTV in the living room. The Ultimate XP was having a problem where after I logged into X the video would go all screwy; it was all static-y and the top half of the video output would appear at the top half of the screen and again at the bottom half. I dragged a real monitor in there and attached it to the end of the external monitor plug on the component and everything displayed normally on the monitor, but still screwy on the TV. I bought a new component and it's doing the same thing. But it only does it in X. This setup worked fine until about a month ago. I'm completely at a loss as to how to fix this. Here's my search for errors in /etc/Xorg.0.log: carter log # grep EE Xorg.0.log (WW) warning, (EE) error, (NI) not implemented, (??) unknown. [42.372] (II) Loading extension MIT-SCREEN-SAVER Does anyone have any idea of what's going on? It only happens in X; it's fine until X loads... -Michael Sullivan-

Naah, North Korea explanation already used 2 days ago... time to use a new reason... Today would be: surge caused by harmonic oscillation between rotating electric motors, you know, like the... building air conditioner! ... followed by some conversation with the management with the end effect of shutting down the building AC but letting the data center AC still operational ...

Yeah, that sounds like an old wives tale urban myth to me too I'll be wanting to be seeing the output of real diagnostic programs All that does, as far as I understand it, is to fool $user into having less space available. So if the partition only has as much space left as is reserved for root, he just can't write anymore. It just means that before the drive gets physically full (which means that files will fragment more), it will get logically full earlier. This is why there can be expected less fragmentation under extreme circumstances (i.e. an almost full FS). -- Gruß | Greetings | Qapla' I forbid any use of my email addresses with Facebook services.

Dale :-) :-) Nowhere. Disk manufacturers measure kilos of data as 1000 Everyone else measures it in 1024 Well, to nitpick, they say it correctly, as for their kilo, 10^3 bytes is correct. We, the binary folk, assert kilo to be 2^10 bytes which is actually called kibi, but we still use kilo in our everyday language thanks to historical ballast (and because, as I recently heard, the -bi units aren't around that long yet). First time I heard of them was in uni lecture ~2003±1. They do this because it fudges disk sizes to appear 2.4% bigger than they really are. When you get into TB drives, it gets worse as 1024*1024*1024*1024 differs from 1000*1000*1000*1000 bu a lot more than 2.4% By 1.024^4, which is 1.0995 to be precise. Those swines are stealing almost 10% from us. :o) -- Gruß | Greetings | Qapla' I forbid any use of my email addresses with Facebook services. “Don't put multiple statements on a single line unless you have something to hide.” – Linux Torvalds, Linux kernel coding style documentation pgpSL7QsyvpZS.pgp Description: PGP signature
Re: [gentoo-user] portage updates
Wouldn't this particular topic be best answered by the dev's of said file systems and what, if any, fragmentation etc, could and can and will happen with the different arguments ie -m 0, etc.? All it is now between everyone discussing this here in a Gentoo list is more or less conjecture, at least what I've read from most posts. Wouldn't the people who make up, design and take care of the file systems in discussion be the best ones to simply ask? Not meaning to 'end' the discussion, just curious as to why no one has gone to those who would know best and brought it up and seeked out the answer(s) from them instead of people who only can guesstimate here. So don't get mad, get glad, heh heh.

So don't get mad, get glad, heh heh. I think one reason may be this, there are people on this list that have more experience than a lot of devs. By that, I mean real life experience. Sometimes what devs expect doesn't actually happen in real life situations. For example, when testing a file system and how it frags, large files, small files or medium size files? Are these files changing or once saved they never change? So, sometimes asking a person who actually uses something can have better advice than the person that created it. Just saying.
