They see this without seeing any other corruption of any kind, and they only see it on files of very specific sizes. They see this without crashing, and without hard drive suspend kicking in. They see it on scsi and ide, on servers and laptops. Elevator bugs and general driver bugs could certainly cause nulls in data files. But they would also cause other corruptions and probably would not be selective enough to pick files that happen to have the same range in size that reiserfs packs tails on. In other words, updating to 2.4.2pre2 or your favorite ac series kernel is probably a good plan. It won't fix this bug ;-) Perhaps I haven't seen it yet because I've also been testing code that does direct->indirect conversions slightly differently, I'll try again on a pure kernel. -chris - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://vger.kernel.org/lkml/

Chris, Do you know if the people reporting the corruption with reiserfs on 2.4 were using IDE drives with PIO mode and IDE multicount turned on? If so, it may be caused by the problem fixed by Russell King on 2.4.2-pre2.

This should be all covered extensively in the reiserfs FAQ and list archives, here a last time: It only applies to knfsd, but unfsd unfortunately has different problems with reiserfs. It makes assumptions about the inode space by the underlying filesystem by assuming that it can encode a dev_t in upper bits. Reiserfs unlike ext2 periodically cycles through the full 31bit of inode values, and after some weeks on a busy file system unfsd starts to complain about conflicts. There is a patch at ftp.suse.com:/pub/people/ak/nfs/unfsd* that works around the problem when you specify --no-cross-mounts (but you cannot export trees of multiple file systems then with a single mount anymore) Please also note that the patch also adds a rather obscure bug, which triggers very seldom (patch partly exists, but not really tested yet) Another alternative is to use knfsd with Chris Mason's 2.4 knfsd patches. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

The reiserfs nfs problem in standard 2.4 is very simple -- it'll barf as soon as you run out of file handle/inode cache. Any workload that accesses enough files in parallel can trigger it. Fixes do exist, but require bigger changes in nfsd. Basically you need to hand out an 64bit inode in the nfs filehandle, and pass the upper 32bits to the low level file system for efficient lookup (actually is all not too difficult to implement, just requires very uncodefreezefriendly changes to nfsd) -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

One of our users in Russia said that reiserfs was as stable as a mountain, and he didn't understand my email. We have some number of users, I wish I really knew how many. If you look at a few hundred thousand mountains, you'll discover that a number of them are really quite unstable. We used to get a bug report a week, now we get one or two a day. Does this mean we went from a few hundred thousand mountains to a few million? I don't really know. I can assure the users though that we have an extensive testing procedure, and that our releases all pass a testing that can roughly be described as hammering the filesystem every different way we can think of (this is more limited than what being put into the kernel by Linus does) for twelve or more hours. What I do know is the following: there was a recent elevator bug fix. Our filesystem is a journaling filesystem and it is extremely dependent on an assumption that nothing is going to get written to disk before it should. I think fsck even makes assumptions about certain states relating to rename being made atomic never reaching disk (and I think this is being fixed thanks to this bug). Could this cause the bug in which syslog gets zeros in it? Don't know, we haven't reproduced that bug yet though it "should" be straightforward to reproduce. We do have an NFS bug, which Nikita is still fixing. What I can tell you is that in a few weeks we will have it back to a bug report every week or two, and until we do version 4 of ReiserFS is going to be stalled (not so different from Linux 2.5 being stalled until 2.4 satisfies Linus).

Want to trigger this? Just install reiserfs on Dual SMP machine with huge RAID acting as mail server for 90k mailboxes.

Actually, I meant to say my hard drive crashing. I have two hard drives, side-by-side, and sometimes they overheat and one of them powers down due to the excess heat. They haven't done that lately, though, as I have a dedicated fan for both of them, but the corruption persists. -- Daniel Stone Linux Kernel Developer [EMAIL PROTECTED] -BEGIN GEEK CODE BLOCK- Version: 3.1 G!>CS d s++:- a C++ ULS$>B P L+++> E+(joe)>+++ W++ N->++ !o K? w++(--) O M- V-- PS+++ PE- Y PGP>++ t--- 5-- X- R- tv-(!) b+++ DI+++ D+ G e->++ h!(+) r+(%) y?

So, it really should be a reiserfs bug. I run Reiser on all but /boot, and it seems to enjoy corrupting my mbox'es randomly.

Oh, I thought that if tails are larger than 2048 bytes, they get converted to ordinary 4k blocks. The last case (with 2312 zero block size) is the only case where the first entry after the zero block is the last entry of the file.

I have to admit that I do not really know: The ad server is a java application, I do not know wether java on linux does mmap for FileInputStream and FileOutputStream. "lsof" shows an ordinary file descriptor (such as "13u") at the FD column for those files, libraries do not have an fd, they have "mem" in the FD section. So I guess that the files are not memmapped, the implementation is easier with ordinary read()s and write()s.

I'd love to blame this on VIA problems, but people are seeing it on other chipsets too ;-) People who report this aren't seeing general corruption, just zeros in files of specific sizes. So, it really should be a reiserfs bug. -chris - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/

Could this bug be related to the reported corruption that people with new VIA chipsets have been also reporting on ext2? It seems similar because of the location of the corruption: http://marc.theaimsgroup.com/?l=linux-kernel&m=98147483712620&w=2 Anyway, it can't hurt to ask the bug reported if they're using a newer VIA chipset and see if they will upgrade their BIOS which seems to fix the problem. -Dave - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] Please read the FAQ at http://www.tux.org/lkml/
