Hm, even something more complicated as you are writing to a file in 4k chunks. Definitely no. And besides, how could it even know whether you even want them to be the same or not. windows uses a signature. I keen plenty of identical files around (online backups, etc) and I'd be mighty upset if the filesystem started hard linking them together :) That is why I said lazy copy on write. This is not patented, it is an old thread, everyone agrees that it should be done, no sponsor at the moment though. One implementation would be for the file system to keep a ref count of how many different files the user intended. When an applicatiion writes to a file, the file system checks the ref count. If the ref count is greater than 1, the file system copies the file, decrements the ref-count, and gives the writing application a pointer to the new copy. I'm sure there are smarter implementations, but the point is that the file system can certainly differentiate in theory between user hard links and actual hard links. -Alex- ___ S.

It would be nice to be able to do fast backup of changed files without having to traverse entire directory trees. No. I would presume that journalling gives access to this sort of recent information. It is really a No. All kinds of metadata is journaled. Also it is possible to get in situation where file was modified, but not journaled, because no metadata changed. (mmaped writes coming to mind). Also journal is not infinite, it is only 32M long. And I presume you want some kind of info like what have changed since week ago. Journal well might be overwritten many times since then. Bye, Oleg

I did a reiserfsck on the drive and noticed that access.01Jun.r.gz returned an error stating the file pointed to nowhere. I was unable to complete a reiserfsck --fix-fixable because of the length of time that this (fsck) process took since this was an unscheduled downtime.

Upon restart they noticed that the file /proj/webtrends/receive/bama/www3/access.01Jun.r.gz was unreadable by root (permission denied). I did a reiserfsck on the drive and noticed that access.01Jun.r.gz returned an error stating the file pointed to nowhere. I was unable to complete a reiserfsck --fix-fixable because of the length of time that this (fsck) process took since this was an unscheduled downtime. During the weekend i will attempt to do the fsck again, however i really needed to know if this problem has been observed by anyone else, and what steps they took to fix the problem. -Kurt -- Kurt Palmer SysAdmin [EMAIL PROTECTED]Advance Internet 201-459-2846

It would make it a lot simpler to apply a LART the guilty part(y|ies) for the duplicate files SPEW. Don't say it can't be done because the netdev folks did it for their list a few months ago. FAQ.idx says: --- 8 --- 9.7 Limiting `Received:'' headers in outgoing messages. Sendmail still is being used on the majority of mail hubs. Sendmail has very primitive loop detection, bouncing messages based on excessive ``hopcount''. The ``hopcount'' is determined by counting ``Received:'' headers. ezmlm by default propagates ``Received:'' headers to facilitate message tracking. Thus, messages, especially from a sublist, can have a number of ``Received:'' headers that exceeds the ``hopcount'' set on poorly configured sendmail hosts. Subscription confirmation requests, warning, and probe messages have fewer ``Received:'' headers. Thus, a user may be able to receive these, but not (some of the) list messages. Of course, the best is to correct the configuration on the bouncing host, but this is often under the control of neither list owner nor user. To compensate for this problem, ezmlm-send(1) of ezmlm-idx-=0.313 by default removes all ``Received:'' headers except the top one. They are still written to the archive, an can be retrieved from there using the ``-getv'' command. To cause ezmlm-send(1) to pass on all the ``Received:'' headers, use the ezmlm-send(1) ``-r'' switch. --- 8 --- so try echo|mail [EMAIL PROTECTED] HTH -- Safari - [EMAIL PROTECTED] Talk is cheap.

Only a 2**128 chance of that. If you know a way to force a hash collision more frequently than that, the crypto world wants to hear from you.. ;) Also this buys you nothing. You write file in chunks, once file is identical to other file, one of the files deleted. Looks like just more extra work (but some saved space of course). A much more productive way to save space is file-system compression. AIX supports LZ-compressing each 4K block and then only saving as many 512 byte fragments as actually needed. It's a big win - /usr (even with all the binaries) needs about 30% less space, and I've seen over 50% for file systems with source trees in them... -- Valdis Kletnieks Computer Systems Senior Engineer Virginia Tech
