Hi 2 all ! I have problems with concurrent filesystem actions on a ocfs2 filesystem which is mounted by 2 nodes. OS=RH5ES and OCFS2=1.2.6 F.e.: If I have a LV called testlv which is mounted on /mnt on both servers and I do a "dd if=/dev/zero of=/mnt/test.a bs=1024 count=1000000" on server 1 and do at the same time a du -hs /mnt/test.a it takes about 5 seconds for du -hs to execute: 270M

Hi all, This is a good news for LVM users, especially for RHEL and CentOS users. You can control I/O bandwidth of your disks easily without hassle, because I've made RPM binary packages of dm-ioband and dm-ioband-config available at http://people.valinux.co.jp/~ryov/dm-ioband/binary.html The RPM binary packages are for Red Hat Enterprise Linux 5.x and CentOS 5.x. They were tested on CentOS 5.3 and will also work on other 5.x versions. Please refer to the on-line manual at http://p...

caching_thread()s do all their work under read access to extent_commit_sem. They give up on this read access only when need_resched() tells them, or when they exit. As a result, somebody that wants a WRITE access to this sem, might wait for a long time. Especially this is problematic in cache_block_group(), which can be called on critical paths like find_free_extent() and in commit path via

I began an update of one of our servers via yum and, coincidentally or not, I have been getting the following logged into the message file since: messages:Jan 7 15:55:51 inet07 kernel: post_create: setxattr failed, rc=28 (dev=dm-0 ino=280175) Now, this tells me that dev dm-0 is out of space but, what is dm-0?

...M as a kernel parameter on a x86_64 hyperviser. It appears that qemu is adding too much overhead to virtual machines to display graphics. If I boot a sles9sp3 domVT in runlevel 5 with vga=0x314 for a graphicalboot, and immediately use vncviewer simply to watch the virtual machine as it boots, qemu-dm consumes 40% cpu as soon as vncviewer is launched and remains that way throughout this entire process without settling down when the login screen appears. Even If I close the console that''s viewing the virtual host, qemu-dm remains at 40-44%. When booting the same domVT in runlevel 5 w...
