kjournald & jbd
Hello everybody, Could someone please explain to me what is the difference between kjournald and jbd (precisely, what does each of them do?) Thank you, Alina _________________________________________________________________ Chat with friends online, try MSN Messenger: http://messenger.msn.com

ext3/kjournald overhead
Hi, I've recently installed ext3 on an 800MB RAID5 (software) array. I am running RedHat Linux 7.1 with the Linux kernel 2.4.12-ac3 on a 1GHz Pentium system with 128MB RAM. I am seeing a significant amount of write operation slowdown when running ext3 (and kjournald), as opposed to my old ext2. The problem seems to be associated with the times that kjournald is accessing the disk. At those moments, my CPU utilization peaks, and network transfer is nearly halted until kjournald is finished. I read in an archive of a Linux Symposium on 20 July, 2000 by Dr. S...

"DRQ after issuing write" error
...le writing a file to an ext3 filesystem, i get some drive errors on the console. I guess is a drive/ide related problem more that a ext3 one, but anyway the debug output is here if you want to take a look. And, by the way, what means that DRQ thing??

kjournald hang on ext3 to ext3 copy
...t3 filesystems on a CompactFLASH. One is mounted as / and one as /tmp. In my test, I am copying a 100 MB file from /root to /tmp repeatedly. While doing this test, I eventually see the copying stop, and any attempts to access /tmp fail - if I even do ls /tmp the command will hang. I suspect kjournald because of the following ps output: PID PPID WCHAN:20 PCPU %MEM PSR COMM 8847 99 start_this_handle 1.1 0.0 28 pdflush 8853 99 schedule_timeout 0.2 0.0 7 pdflush 188 1 kswapd 0.0 0.0 19 kswapd0 8051 1 mtd_blktrans_...

kjournald using up majority cpu%.
We run several RH7.2/7.3 servers & recently 2 of them, although still working fine, have started to show kjournald as generally using over 50% cpu% on 'top' - virtually continuously. Free cpu% generally less than 25% now! Both machines are also using software RAID5 EIDE ....... otherwise are standard server installs. Any info on what kjournald is & why it should have recently become so active wou...

kjournald tuning
...tats coming from vmstat. What initially appeared to be happening is the machine goes into a hard loop in some mod_perl webserver code. Now there still may be an issue with the code, but my code examinations show no possible way this could be happening, but what I'm writing to you about is kjournald. When this apparently looping state is reached, kjournald shows D state for several seconds. During that same time, block-out "bo" in vmstat consistently shows 0. kjournald is choking. Or something. Also, this appears to get a lot of processes looping on write somewhere in the webserve...

kjournald pegging cpu
kernel version 2.6.10-1.771_FC2smp We have had quite a few instances of kjournald pegging cpu and thereby effectively knocking out the system's i/o. What can we do to provide more information so that the cause can be identified and fixed? Thanks Christopher

Ext3fs performance/kjournald deadlock issue
...onally, I can't play mp3 files from a samba share on this machine without winamp pausing every 5-10 seconds. If I copy the mp3 files to the local hard drive or to a samba share on a Redhat 6.2 system (running ext2fs), the files will play fine. I have noticed that cp/smbd seems to deadlock with kjournald. I haven't modifed any of the ext3fs settings. Can I improve performance by changing the journal settings? I think the default is to update the journal every 5 seconds? If I increase that to 60 seconds would that improve performance? I've updated the system via RHN, but the performance is...
