similar to: ext3 and bdflush tweaking

(Sent to linux-raid, linux-kernel and ext3-users since I'm not sure what type of issue this is) I've got a test system here running Redhat 7.1 + stock 2.4.9 with these patches: http://www.fys.uio.no/~trondmy/src/2.4.9/linux-2.4.9-NFS_ALL.dif http://www.zip.com.au/~akpm/ext3-2.4-0.9.6-249.gz http://domsch.com/linux/aacraid/linux-2.4.9-aacraid-20010816.patch All three patches applied

Our Invoice posting routine (intensive harddrive io) freezes every few seconds to flush the cache. Reading this: https://listman.redhat.com/archives/ext3-users/2002-November/msg00070.html I decided to try: # elvtune -r 2048 -w 131072 /dev/sda # echo "90 500 0 0 600000 600000 95 20 0" >/proc/sys/vm/bdflush # run_post_routine # elvtune -r 128 -w 512 /dev/sda # echo "30 500 0 0

I'm lacking some understanding of how to tune / when to tune /proc/sys/vm/bdflush Where can I read up on this? Our current problem: Load is low, but ever so often the system decides to do some serious disk I/O which causes all processes to wait for disk I/O -- load explodes (rises linear up into the 20-30ies) just to fall linearly (spelling?) right after that. We think there might be some

Greetings all, I have a question regarding the fsync data corruption bug that was introduced in 2.4.20 when using data=journal. I have patched the 2.4.20 kernel with the 3 sync patches available from zip.com.au, and I am wondering if with these patches the "bug" still exists: sync_fs.patch sync_fs-fix.patch sync_fs-fix-2.patch In addition the following two patches have also

Well.... you might remember that I have had problems will my NFS fileserver that run ext3 with data=journal. The filesystem corruption now seems too be solved with the patch (plus amendment) that I posted, so I am happy about that... but there is more. I have known for a while that ext3 doesn't behave very well when the journal fills up. If it finds that the journal is full, and the

Hi, I am a new ext3 user and I am having some problems. I seem to have introduced a memory leak after adding ext3 support to the kernel. I noticed when running top or viewing /proc/meminfo my free memory pool seems to be decreasing while my buffers are increasing (around the same rate). I am currently using a root partition and a /var partition. I have listed the ext3 boot messages below.

Suppose I have the latest and greatest e2fsprogs. >From reading the docs I understand that 1) boot ext3, clean umount - you can remount ext3 or ext2 2) boot ext3, unclean umount - you can remount ext3 - you can e2fsck and remount ext2 Does this mean that normal linux init script e2fsck will do it, in case fstab says ext2? Or you should make sure to run e2fsck by hand with -f? 3) boot

Get this warning on bootup ext3 file checks on 2.6.* kernels. Apparently harmless, but how do I fix this? _______________________________________________ debian-knoppix mailing list debian-knoppix at linuxtag.org http://mailman.linuxtag.org/mailman/listinfo/debian-knoppix

Dear All, I have a query : what is the command to count number of repeated words in a column. for ex: a = oranges oranges apples apples grape oranges apple pine the result should be oranges 3 apples 3 grape 1 pine 1 is there an easy way for this.

Hello companions!!! I have a function that creates a Radio Buttons, and I need that this function return the selected value in the Radio Buttons. I would like that, if somebody know as I could return the value, you say me as do it. Next, I show the function function1<-function(){ require(tcltk) tt <- tktoplevel() rb1 <- tkradiobutton(tt) rb2 <- tkradiobutton(tt) rbValue <-

Let's say that I have a bunch of matrices. They look like this (pardon using fruit for examples, my actual data tables are far too enormous): Matrix1 Apples Oranges Pears A 5 6 7 B 5 3 4 C 8 9 10 D 11 13 14 E 15 3 8 F 1 4 5

Hi Andreas, Stephen, We have a lot working now: 1. journal recovery and initialization stuff is working 2. transactions go to the disk 3. infrastructure is there to do transcactions 4. ext3_create is fully operational. The problems we have seen mostly have to do with differences in which buffer heads are being initialized. Things like b_transaction etc. were not cleaned up. There are more

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

hi, i'm implementing journaling support in vfat, basically i'want to know that how kernel come to know about unclean unmount at the time of reboot, if i'm not wrong it must be checking this before mounting a filesystem. plz help me in this regard as soon as possible. cheers ravi

I am getting an odd situation when backing up a number of ext3 filesystems and was wondering if it could be caused by journalling. Over the space of a minute the load average will jump from 2 to over 40 and the system will be unresponsive for anywhere from 8 to 25 minutes. I am going to be trying a number of things, but was wondering if anyone could see the reason for the high load given the

I have kernel 2.4.16 with ext3 compiled (not as a module), with redhat 7.1, and downloaded lilo 22.1 from util-linux 2.11n but still, on init the root fs is mounted initially as ext2 as read-only, afterwards it is unmounted and mounted again as read-write ext3. this causes problems upon unclean shutdown where I have to fsck it just like ext2. does anyone know this problem ?

Just wanted to note that you also need "mount" => 2.11 to use "auto" in fstab. On the homepage http://www.uow.edu.au/~andrewm/linux/ext3/ it only tells you to use "util-linux" => 2.11 Also, a note about SILO not working with unclean Ext3 would be nice (i.e. make a dedicated ext2 /boot partition if you want to run ext3 on Sparc). /Martin (very new to this list)

Hi. I found and reported a bug about a year ago regarding symbolic links but haven't seen any mention of it since and it is still present in 2.6.1-pre2. Just want to make sure it isn't forgotten. It can be reproduced by synchronizing two directories, one of which contains a normal file and the other has a symlink of the same name. With the archive, update and backup options set, rsync

The size of static libraries is relevant because it places an upper bound on the size of the executable. Otherwise we can only speak anecdotally about "typical" executables that use "some" of the
