Is there any faster and reliable way to checksum whole paritions (not on "per file" base)??? Thank you very much in advance for any help! Best regards, mcc Constructing a checksum means reading every byte off the partition. So it's slower as a copy to /dev/null, never faster (because the checksum calculation also needs time.) So in order to determine whether it's really slow, compare the time needed to dd the whole partition to /dev/null to the time needed for checksumming it. Then post the times here and an expert might then tell whether this can be improved at all or not.

> Is there any faster and reliable way to checksum > whole paritions (not on "per file" base)??? It depends on where your bottleneck is... If you're cpu-bound you can try with a faster hash: md5sum or even md4sum would be a good choice (collision resistance is irrelevant in this application). On the other hand, if you're limited by disk throughput (which is most likely) there is not much you can do. After all, you have to read the data in order to hash it, and that takes time. andrea

It means that you can dump a lot of text "documents" into it (based on html pages, database records, actual documents, etc). sphinx efficiently indexes all the text in it, and then allows you to retrieve it again, supporting things that are useful for searching in text such as stemming. It can use MySQL but this isn't needed to use it.

Re: [gentoo-user] Re: One hard drive much slower for some reason.
You could still be looking at a hardware failure situation here. I have seen hard drives with absolutely perfect SMART attributes pass all the tests but still show the classic signs of a hard drive beginning to fail. A significant slowdown is one of those signs. What I would suggest is that you find some way to observe the hard drive over a long period of time at considerable load. If there is a problem, eventually it will show up in the SMART attributes. It's not an ideal solution, and your problem may not be hardware failure, but it would be a good idea to rule that out before pursuing any other diagnostic methodologies.

It about has to be hardware at this point. The other drive on the same cable is doing fine. It's not like I picked the wrong driver in the kernel, the other drive would be slow to if that was the case. The drive is pretty old to. Of course, it's not as old as the others but it is a different brand too. Thinking about getting a new 1Tb drive. ;-) Dale :-) :-)

FWIW, portage has a tool called "dcfldd" that works well for me. It is dd with the addition of: * Hashing on-the-fly - dcfldd can hash the input data as it is being transferred, helping to ensure data integrity. * Status output - dcfldd can update the user of its progress in terms of the amount of data transferred and how much longer operation will take. * Flexible disk wipes - dcfldd can be used to wipe disks quickly and with a known pattern if desired. * Image/wipe Verify - dcfldd can verify that a target drive is a bit-for-bit match of the specified input file or pattern. * Multiple outputs - dcfldd can output to multiple files or disks at the same time. * Split output - dcfldd can split output to multiple files with more configurability than the split command. * Piped output and logs - dcfldd can send all its log data and output to commands as well as files natively. e.g. when I copy my HD, I get a copy status report and hash by using the following commands: #!/bin/bash dcfldd if=/dev/sda bs=4096k sizeprobe=if status=on hashwindow=0 of=/dev/sdb dcfldd if=/dev/sdb bs=4096k sizeprobe=if status=on hashwindow=0 of=/dev/null When they've completed, I'll visually compare the two hashes (you can automate this.) You can get fancier and do the Verify instead of the hashes. HTH (p.s. Part of your answer is setting the best blocksize for dd or dcfldd. I'd presume it the smaller of your available memory, or the buffer size on your HD?.. someone please correct me on this!?)
[gentoo-user] Fatal problem: Pyton-updater "kills" PC
hallo,
This morning I updated my newly installed Gentoo.
Via "eselect read news" I was told, that a new
python version (3.1.*) was installed and I should
run python-updater, which I did.
while compiling boost, the PC was killed. It looks
like it was told to switch off itsself.
I rebooted the PC into runlevel 2 and repeated the
whole thing. Again compiling/merging boost kills
the PC the same way.
I rebooted the PC into runlevel "S". After starting
python-updater compiling/mergeing boost kills the
PC.
Each time it looks like someone has switched off the
power.

Anyway, those UDMA errors are a bigger problem I suspect, as they will slow things down as the disk has to recover from the errors. Are you seeing any of the numbers change as you leave it running? RobbieAB Right now its not even in use. It's not mounted or anything but it is getting power. I was using a week or so ago for /var and something else. I can't recall at the moment. I'm not sure if I am going to us it anymore or not. If it stays this slow, I know I'm not. lol Got to love newegg for this part.

Firefox's middle-click url-paste only works if your middle click is not in the address bar. If you middle-click in the address bar, the regular buffer-paste mechanism takes over (i.e. it will paste your selection buffer without deleting what's previously on the address bar). So, we have three copy-paste mechanism: - Ctrl+C/Ctrl+V, we're all familiar with this - Buffer-Paste, provided by X, pastes your selection buffer to hovered textbox - Url-Paste, provided by Firefox, loads the URL in the selection buffer, which as a side effect, replaces the address bar with that url

Just boot up knoppix, mount root partition that contains dcfldd, go to wherever the executable is located (e.g. /usr/bin/dcfldd): 1. boot up knoppix 2. create a partition: mkdir /work 3. mount /work to the root partition: mount /dev/sdc /work 4. cd /work/usr/bin 5. run dcfldd: ./dcfldd If your root partition is encrypted (e.g. mine is), then place a copy of dcfldd on the boot partition; no boot partition, put a copy on its own dedicated little partition. Of course, you can always put a copy on a USB jumpdrive. As a last alternative, download and compile a copy while in knoppix. > Or is there a way to do such copies from a one disk to another while > one disk is booted??? Sure, but the running disk/sector would have temporary files that would not consistently hash when you did the hash check. If you do this, try it in linux without bringing up X. This might avoid copying some software "locks" that could block startup on the copied disk/sector. HTH

If you can put your HTML pages into a database, Sphinx might be able to help you with your issue. Basically what Sphinx does is let you search databases. You specify one or more SQL sources of data ans associated queries, and Sphinx provides an API (or a emulated SQL server) that makes searching easy. Sphinx is for full text database searching; it does not index files or websites directly. (Note that is this not actually true; it can search XML files directly, but you still specify XML attributes instead of database columns, etc, so it is treating the XML as a data store and not as a generic document.) I recall reading that Craigslist uses Sphinx to search their database of listings. As an example of how it works, suppose I am making a news website and have a bunch of news posts, each of which has an author, category, and text. With Sphinx, I can setup a source -- let's call it news_catalog -- that will index this data. news_catalog will be associated with an SQL query that will allow Sphinx to access the data it needs to index. Let's use "SELECT id, author, category, text FROM catalog" as our query. Note that catalog is a table or view in your database, though this query can also use complex joins, etc, as long as the database supports it. Via the Sphinx API, I can say I want to search for "Europe | America" and it will return a list of news articles containing the terms Europe, America, or both, as a pipe is the or operator. It actually returns a list of ids which correspond to the id I specified in my query; a unique key is always the first argument in the query. My application is responsible for fetching the actual data from the original database using that id and presenting the data in a useful way to the user. Extended query syntax allows for other boolean operators, searching specific fields, strict order, exact match, field start/end, etc. The documentation has lots of examples; look at http://www.sphinxsearch.com/docs/current.html for the current reference manual. If you have a bunch of HTML files on a disk or website that you want to index and search, I do not think Sphinx is the software you want. Yes, you could load your data into a database and then use Sphinx, but that does not seem like the best solution. Sphinx provides the API for use in your application; it does not provide a user interface. As an alternative, I recommend you look at something like ht://Dig (htdig.org), which will search HTML pages directly in addition to PDF, Word, Excel, Powerpoint, etc with the help of external converters. It also includes a user interface. After glancing at webglimpse, with which I am not familiar, it looks like it does something similar to ht://Dig. Regards, Brandon Vargo
