similar to: with heavy VM IO, clocksource causes random dom0 reboots

I have the exact same issue on several Sunfire v20z (hardware LSI RAID controler). Under high IO load, the raid controler starts complaining with disk errors : [163442.483878] mptbase: ioc0: LogInfo(0x11070000): F/W: DMA Error [163445.172333] sd 2:0:0:0: [sda] Unhandled error code [163445.172338] sd 2:0:0:0: [sda] Result: hostbyte=DID_SOFT_ERROR driverbyte=DRIVER_OK [163445.172345] sd 2:0:0:0:

Hi all, I'm not sure if this is really rsync related so fell free to ignore this message ;) I have to server. The first one is rsync server et and the second one the client. The rsync server repo is around 325Go. Every time my client start rsync, both rsyncd on the server and rsync on the client entered "Uninterruptible sleep" state and I can't figure out why. Server : -

Hi all, We have been using SuSE7.2 and samba (client and server) without any problems for a few months. Now, we migrated some workstations (samba clients) to SuSE8.0 and we get segfaults while accessing files mounted through samba. The segfault happens on the CLIENT side. Here is our network configuration: - SuSE7.2 server with default samba server package. - Few SuSE7.2 workstations

Since the d_off in the first dirent for "." (that originates from the 4th argument "offset" of filldir() for the 2nd dirent for "..") is wrongly assigned in btrfs_real_readdir(), telldir returns same offset for different locations. | # mkfs.btrfs /dev/sdb1 | # mount /dev/sdb1 fs0 | # cd fs0 | # touch file0 file1 | # ../test | telldir: 0 | readdir: d_off = 2,

Hello, On a VM guest (running under KVM) with CentOS 5.8, I yesterday strangely got the following (see below). The server runs apache/php/squirrelmail/postfix/dovecot/openldap and it is a production server. Do you advise to do some particular file system checks or other settings? Any other advice? Such errors have not appeared in the past. Thanks, Nick System info:

We should call ocfs2_inode_lock_atime instead of ocfs2_inode_lock in ocfs2_file_splice_read like we do in ocfs2_file_aio_read so that we can update atime in splice read if necessary.

Hello When using readdir() on a directory with many files or long file names it can happen that it returns the same file name twice. Attached is a program that demonstrates this. I have traced this problem back to linux-2.6.10-rc1-bk18 and all kernels after this one are effected. linux-2.6.10-rc1-bk17 is still okay. If I reverse the following patch in linux-2.6.10-rc1-bk18, readdir() works again

ocfs2_queue_orphans() has an open coded readdir loop which can easily just use a directory accessor function.

I''m having a problem with the boot sequence hanging indefinitely at "stopping system V runlevel compatibility". Here are the steps I took to get to this point: 1) installed a single boot, server version of ubuntu 11.10 (intended to be dom0) 2) apt-get install xen-hypervisor-4.1-amd64 xen-utils-4.1 xenwatch xen-tools xen-utils-common xenstore-utils 3) updated grub as follows: -

Dual Opteron system running ext3 atop drbd (network RAID) devices, which, in turn, are atop LVM logical volumes. The underlying device is hardware SCSI RAID via a LSILogic HBA. The kernel is vanilla 2.6.13 on a Gentoo-based system. A panic occurred, which contains references to ext3 code. I'm not sure how others manage to get these typed out, but I'm manually typing it from

Hello. I''ve built a kernel from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git (Date: Fri Nov 19 19:46:45 2010 -0800) and got a kernel oops when tried to access to unplugged, but mounted external usb storage formatted with JFS. Steps to reproduce: mkfs.jfs /dev/sdb1 (unpluggable USB hard drive) mount /dev/sdb1 /mnt/drive cd /mnt/drive touch test sync

filldir_t can take this, so don't turn de->inode into a 32 bit value. Right now this doesn't make a difference since no ocfs2 inodes overflow that, but it could be a nasty surprise later on if some kernel code is calling ocfs2_dir_foreach_blk() and expecting real inode numbers back...

Hi, I have found the cpu time partitioning based on cpu shares weights not very intuitive. On RHEL64, I deployed two qemu/kvm VMs VM1 with 1 vcpu and 512 cpu shares VM2 with 2 vcpus and 1024 cpu shares I pinned their vcpus to specific host pcpus: VM1 vcpu 0 to host pcpu1 VM2 vcpu 0 to host pcpu1, VM2 vcpu 1 to host pcpu2 I executed inside the VMs a simple process that consume all

From: Zach Brown <zab@zabbo.net> ocfs2''s .aio_read and .aio_write methods are changed to take iov_iter and pass it to generic functions. Wrappers are made to pack the iovecs into iters and call these new functions.

Hi , I have two virtual machines VM1 and VM2. Then I have added eth0 of my VM to 'default' network. Use case :- I want to monitor all traffic on virbr0('default' network). Steps followed :- 1. Add VM1 eth0 to virbr0 2. Add VM2 eth1 to virbr0 3. brctl setageing ovsbr0 0 ..(To put bridge in promiscuous) Now I am running tcpdump on eth1 of VM2 and trying to ping
