Hi all, Man page of tune2fs says that max journal size is 102,400 filesystem blocks, which translates to ~100MB with 1kb blocks or ~400MB with 4kb block. I wonder - why this limitation exists? Now that relatively cheap ssd devices exist (gigabyte iRam) that offer up to 4GB of space, it would be extremely useful to use whole capacity of such device for full data journaling. -- Jure Pe?ar

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

Hello, As a Virtuozzo users we have majority of our diskspace formatted with -i 1024 -b 1024. Lately I discovered that on CentOS 4.6 ext2online barfs when I try to grow such filesystem. Running it with -v -d, it prints lots of lines like: ext2online v1.1.18 - 2001/03/18 for EXT2FS 0.5b ext2online: 873646830 is a bad size for an ext2 fs! rounding down to 873644033 ... group NNN inode table has

Can anyone explain how the disk elevator works and if there is anyway to tweak it? I have an email server which likely has a large number of read and write requests and was wandering if there was anyway to improve performance. Matt

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

Hi all, We are observing a consistent interval of about 4 minutes at which there are large sustained writes to disk that causes mysqld to block and not respond for the entire period. We are using data=journal with a 128M journal and the filesystem is 150GB in size. We get about 300kb/sec in writes and that will jump to about 2000kb/sec during the periods of large sustained writes. Those

Hello, I just noticed that centosplus for c4 provides mysql 5.0.54, while centosplus for c5 does not provide that recent version and so c5 is stuck with mysql 5.0.22. Any particular reason for that or it is just that no one has yet compiled & packaged 5.0.5x for c5? Also, where does 5.0.54 comes from? MySQL site is only at 5.0.45 rpm and 5.0.51 source ... -- Jure Pe?ar

Hello, I seem to recall from my redhat5/6/7 days that certain installation methods used for kickstarting only invoked text mode install. Now I read that graphical install is default in kickstart on el5/6. However, in my test environment (with older HP DL140G3) I only get text mode install up, even if I specify graphical in kickstart file, with both nfs and http install methods. There's no

Hi all, I'm debugging a performance problem for a client. Needless to say, the organisation of their data is such that this problem is really annoying. Here's the situation: Samba 3.0.x PDC in a mixed 9x/nt/xp environment, using acls. When trying to delete a large number of folders from a folder, the 'preparing to delete' stage takes about half hour. It's simple to repeat:

About two weeks ago i was whining about an inode that got lost, now i'm going to whine more about strange things happening here. A matroxfb just oopsed on me (thats not strange), the machine got unusuable, so i logged in from another and got the idea to touch /forcefsck. Upon reboot, fsck said that some inodes are in use but have dtime set and that some files are illegal sockets. Now this

Hi list, I just finished building a custom kernel from 2.6.18-53.1.21 source rpm - this time with ISA bus and ISAPNP support which I accidentally left out of my previous attempt. Unfortunately, this time I forgot to change my identifier in kernel-2.6.spec file. Thus I now have one *installed* kernel version *without* ISA support, and another one *with* ISA support but as rpm, not yet installed.
