Ceph

I deleted this article because it was copied & pasted from [1]. It was tagged as a copyvio for two weeks so there was enough time for people to make a non-copyvio version. Besides, you're free to create the article again. As long as it's not a copyright violation. Garion96 (talk) 20:00, 30 May 2007 (UTC)[reply]

License tagging for Image:Ceph-logo1.jpg

Thanks for uploading Image:Ceph-logo1.jpg. Wikipedia gets thousands of images uploaded every day, and in order to verify that the images can be legally used on Wikipedia, the source and copyright status must be indicated. Images need to have an image tag applied to the image description page indicating the copyright status of the image. This uniform and easy-to-understand method of indicating the license status allows potential re-users of the images to know what they are allowed to do with the images.

For more information on using images, see the following pages:

This is an automated notice by OrphanBot. If you need help on selecting a tag to use, or in adding the tag to the image description, feel free to post a message at Wikipedia:Media copyright questions. 11:06, 4 June 2007 (UTC)

Ceph

A "{{prod}}" template has been added to the article Ceph, suggesting that it be deleted according to the proposed deletion process. All contributions are appreciated, but yours may not satisfy Wikipedia's criteria for inclusion, and the deletion notice explains why (see also "What Wikipedia is not" and Wikipedia's deletion policy). You may contest the proposed deletion by removing the {{dated prod}} notice, but please explain why you disagree with the proposed deletion in your edit summary or on its talk page. Also, please consider improving the article to address the issues raised. Even though removing the deletion notice will prevent deletion through the proposed deletion process, the article may still be deleted if it matches any of the speedy deletion criteria or it can be sent to Articles for Deletion, where it may be deleted if consensus to delete is reached. --Onorem Dil 16:19, 4 June 2007 (UTC)[reply]

Hello Onorem Dil. If you which to delete the page Ceph I also recommend you consider the pages GlusterFS, Gfarm file system and MogileFS. That will cover up all the free software distributed parallel fault tolerant file systems currently represented on Wikipedia. Also, check out PVFS and Lustre (file system) those articles are on similiar subjects, although not fully fault tolerant. JerkerNyberg 18:40, 4 June 2007 (UTC)[reply]

Thanks for pointing those out. They have all been tagged as being insufficiently sourced too. Notability needs to be established by multiple independent reliable sources. --Onorem Dil 18:50, 4 June 2007 (UTC)[reply]

If you check out the proprietary ones, there are Google File System, IBRIX Fusion represented on Wikipedia. Among the free software shared disk file systems there are at least two represented here on wikipedia, Global File System and OCFS. Both are included in the Linux kernel. Don't forget Coda (file system) and InterMezzo (file system). If you go through the List of file systems you will probably find several more that do not fit. JerkerNyberg 19:08, 4 June 2007 (UTC)[reply]

Right now, none of the tags I have added have anything to do with deletion. It's not that I really want these articles to be deleted. I want them to be properly sourced, and that doesn't happen as often without some threat of deletion. Just to be clear, I'm not an admin. I can't delete any of these. All I can do is tag them for administrator attention. --Onorem Dil 22:03, 4 June 2007 (UTC)[reply]

Orphaned non-free image (Image:Ceph-logo1.jpg)

Thanks for uploading Image:Ceph-logo1.jpg. The image description page currently specifies that the image is non-free and may only be used on Wikipedia under a claim of fair use. However, the image is currently orphaned, meaning that it is not used in any articles on Wikipedia. If the image was previously in an article, please go to the article and see why it was removed. You may add it back if you think that that will be useful. However, please note that images for which a replacement could be created are not acceptable for use on Wikipedia (see our policy for non-free media).

If you have uploaded other unlicensed media, please check whether they're used in any articles or not. You can find a list of 'image' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "Image" from the dropdown box. Note that any non-free images not used in any articles will be deleted after seven days, as described on criteria for speedy deletion. Thank you. BetacommandBot 21:20, 16 June 2007 (UTC)[reply]

Archive of discussion at User_talk:Naconkantari

Sorry to bother you, but my question is why the page Ceph was deleted. As far as I know the following has happened:

Page created by someone, as far as I know one of the writers of a paper regarding Ceph. Content of the page was very similiar of the abstract of the paper. Page tagged as having copyright problems. Paged deleted.
I asked why and got a resonable explanation. http://en.wikipedia.org/wiki/User_talk:Garion96#Ceph
I created a new page, with my own words describing the features of the file system. Page tagged as blatant advertising. Page deleted.
I created a new page, where I compared this file system with similiar other file systems and explained why it was significant. Paged tagged again. So I slimmed down the page to just the skeleton, while trying to figure out how a page regarding such content should be written. But then, page delteted, blatant advertising.

So. What I am mostly interested in is distributed parallel fault tolerant file systems. There are not so many around. The usage of them is slowly growing. They are in my impression a very important technology since this is where the current supercomputing clusters are heading, this where large scale webhosting is heading and Googles successfull implementation is one of the cornerstones behind Googles success. This the kind of technology that for example would make a very large wiki a lot easier to implement. How should such a article be written to be accepted to Wikipedias administrators? --JerkerNyberg 07:55, 7 June 2007 (UTC)[reply]

I also discuessed the reason behind the tagging on my talk page http://en.wikipedia.org/wiki/User_talk:JerkerNyberg and got the impression that they were not sourced, which I was planning to add. --JerkerNyberg 07:58, 7 June 2007 (UTC)[reply]

In the criteria for blatant advertising: Note that simply having a company, product, group, service, or person as its subject does not qualify an article for this criterion; an article that is blatant advertising should have inappropriate content as well. The page that was deleted didn't say much more than Ceph is a distributed fault tolerant parallel file system or something like it which can hardly be called inappropriate. So? Can you undelete the page you deleted please, or give a better explanaition? --JerkerNyberg 12:19, 8 June 2007 (UTC)[reply]

Well, I've started the new Ceph article myself and haven't received any complaints. I haven't seen your revisions so I don't know how applicable this is, but in general the key is: resist the temptation to echo empty buzzwords such as "Ceph is a distributed network file system designed to provide excellent performance, reliability, and scalability" — because that's what nearly every distributed file system aims to achieve. It's is the sort of claim you find on advertisement brochures in bold letters. Yet it says absolutely nothing.

Instead of cramming all features into the opening sentence, they should be described at a slower pace and in context. -- intgr [talk] 15:01, 21 November 2007 (UTC)[reply]

Thank you for your reply. I think you are refering to the original page by the authors that got deleted by copyright reasons. The last not small page that I wrote that got deleted looked like the following: --JerkerNyberg (talk) 19:11, 22 November 2007 (UTC)[reply]

Ceph
File:Ceph-logo1.jpg
Developer(s) University of California, Santa Cruz
Operating system Linux
Type Distributed file system
License LGPL
Website http://ceph.sourceforge.net

Ceph is a free software distributed fault tolerant parallel file system.

Development
[edit]

Ceph is still in development, please check out the project homepage at http: //ceph.sourceforgen.net This makes Ceph not suitable for building large systems right now, like Lustre i s.

Features
[edit]

Like all other free software distributed parallel fault tolerant file systems, which there aren't so many around, Ceph has certain features. Basic ones, like many servers work together is obvious. So let's list the unique ones:

Adaptive metadata. This means that a single directory may be distributed among many servers using a hash-like function. A simple example of this may be a mailserver using Maildir for storage, with a couple of millions mail in a single storage, getting hammered by all servers at once.

Fault tolerance. Together with GlusterFS, Ceph has built in fault-tolerance. This means a file may be automatically replicated among many servers.

High performance. Like GlusterFS and Lustre, Ceph may stripe files over many servers. Ceph has a good througput on also small files, using a custom disk object file system on the servers.

List of file systems

Gfarm file system

Lustre

And then I wrote a very short one, just a placeholder probably like the first paragraph above, that also got deleted. --JerkerNyberg (talk) 19:17, 22 November 2007 (UTC)[reply]

Fair use rationale for Image:Thinlinc-logo.png

Thanks for uploading or contributing to Image:Thinlinc-logo.png. I notice the image page specifies that the image is being used under fair use but there is not a suitable explanation or rationale as to why each specific use in Wikipedia constitutes fair use. Please go to the image description page and edit it to include a fair use rationale.

If you have uploaded other fair use media, consider checking that you have specified the fair use rationale on those pages too. You can find a list of 'image' pages you have edited by clicking on the "my contributions" link (it is located at the very top of any Wikipedia page when you are logged in), and then selecting "Image" from the dropdown box. Note that any non-free media lacking such an explanation will be deleted one week after they have been uploaded, as described on criteria for speedy deletion. If you have any questions please ask them at the Media copyright questions page. Thank you. NOTE: once you correct this, please remove the tag from the image's page.

Disputed fair use rationale for Image:Lustre logo.gif

Thanks for uploading Image:Lustre logo.gif. However, there is a concern that the rationale you have provided for using this image under "fair use" may be invalid. Please read the instructions at Wikipedia:Non-free content carefully, then go to the image description page and clarify why you think the image qualifies for fair use. Using one of the templates at Wikipedia:Fair use rationale guideline is an easy way to ensure that your image is in compliance with Wikipedia policy, but remember that you must complete the template. Do not simply insert a blank template on an image page.

If it is determined that the image does not qualify under fair use, it will be deleted within a couple of days according to our criteria for speedy deletion. If you have any questions please ask them at the media copyright questions page. Thank you.BetacommandBot (talk) 21:36, 2 January 2008 (UTC)[reply]

davfs2

Hi, awhile back, you copy-edited the davfs2 article. It's now going through an AfD... If you have time could you help with the article? I did some of the lastest work trying to improve it, but it may be insufficient to keep it around. Please help if you can/care. --Mokhov (talk) 05:15, 15 September 2009 (UTC)[reply]
