Hi all, i wanted to ask you all about the exact overwrite mechanism used in ext3; is the information in the datablocks overwritten or written to a new location and the information in the referring inode is changed? Is it depending on the application used (and the functions it calls) or independent from that? Please don't hesitate to go into further details and thanks for your help! cheers, flo This messag...

...ormation from the existing ext2/ext3 filesystem. Why there are ext2_inode datastructure defined in these programs ? Why couldn't these programs read existing datastructures of inode ? 3. Are these user level or kernel level programs ? 4. I want to have my own policies of allocatiing datablocks in some cylinder group instead of using ext2 default policy ? What should I do for that ? I know, these must be silly questions, but I will learn from your response. Mir. -------------- next part -------------- An HTML attachment was scrubbed...

Is there such a filesystem available? It seems like it wouldn't be too hard to implement... Basically do things on a block by block basis. Store md5 of a block in the table, and when writing a new block, check if the md5 already exists and then point the new block to the old block. Since md5 is not guaranteed unique, might need to do a diff between the 2 blocks and if the blocks are indeed

...h to rsync, whereas this time I was doing individual files. I'm guessing that caused a different default behavior. After I started using --no-whole-file and --inplace, the situation improved. For files that had few differences, it was quite fast. However, for files that had lots of modified datablocks, it was still taking much longer than an rcp would. An rcp of a 4gb datafile took about seven minutes whereas rsync with about 10% modified data took about half an hour as shown: -- > Syncing Datafile: /c03/oradata/can/ard04.dbf @ Fri Aug 26 11:46:08 EDT 2005 Number of files: 1 Number of fil...

Hi, as I mentioned in earlier mail to ext3-users I have been getting some corruption on an ext3 filesystem that has been serving NFS. I am now confident that I fully understand the problem and have a patch. It only affects data=journal mode and I wonder if it might also be the cause of the corruption noted by a number of people on linux-kernel. First I will explain the problem. Then display

I''ve noticed that using several TimedObservers (prototype.js) on a page to watch for changes to text fields (haven''t tried forms) can have a non-negligible effect on the CPU cycles used by the browser process. Nothing dramatic, to be sure, but unnecessary. Autocompleter.Base (controls.js) follows a smarter strategy to watch for changes. Currently this functionality is tied

Hi all, I'm in the final stages of putting a new Vorbis RTP draft together, the new sections are below. There are a number of open questions: 1.) At present there is a 16 bit length field for the codebooks. As they are spec'd as being unbound in length, but typically around 15K, are there situations where they may be greater than 64KB? The size limit can be extended to 2MB as there

Bellow, follows a proposal for a new opensolaris project. Of course, this is open to change since I just wrote down some ideas I had months ago, while researching the topic as a graduate student in Computer Science, and since I''m not an opensolaris/ZFS expert at all. I would really appreciate any suggestion or comments. PROJECT PROPOSAL: ZFS Compression Algorithms. The main purpose of

Hi all, Apologies in advance, this email is quite long. I've prepared an updated Vorbis RTP Internet Draft, which is a continuation of draft-moffitt-vorbis-rtp-00.txt which can be found below. If this new draft gets the ok I'd like to submit this to the AVT WG later this week. There are a number of changes over the original I-D, notably the changing of the M bit function in the RTP

Hello, I have my work on the nv vpe video decoder in a functional state. In case you didn't know this decoder accelerates mpeg2 video at the idct/mc level. I have verified that it works on nv40 hardware. I believe it works on nv30 hardware (and maybe some earlier hardware), but I cannot verify since I have none. I will reply with patches against the kernel, drm, ddx and mesa for

Hi All, Please find below an updated Vorbis-RTP Internet Draft document for review and discussion at the Xiph IRC meeting on Saturday. The changes in this version have been: Codebook caching mechanism Expanded SDP parameters Expanded MIME section Expanded introduction Packet loss section Minor tweaks and clarity changes to text There are probably some minor tweaks to the formatting needed
