How to fasten btrfs?
Hi, I am using 2.6.36.3 kernel with btrfs, 512MB memory and a very slow disk, no special options for mounting btrfs except noatime. Now I found it very slow. When I rm a 5GB movie, it took 20 secs. -- 竹密岂妨流水过 山高哪阻野云飞 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@vger.kernel.org More majordomo info at

Emergency help needed on host network randomly stop working.
Hi, This is a Centos 5.5 host with one xen guest. About 2 weeks ago, the host randomly lost network connection. By this I mean I could not connect to the services on it, or ping it.

No clue (any error messages) in messages or dmesg. ifdown/ifup the interface did not help, either. Only

virsh cannot list broken guest.
Hi, I am starting to learn using libvirt with kvm on CentOS 6. Just used this command to start a guest: virt-install -ntest -r1024 --vcpus=1 -c/var/lib/libvirt/images/CentOS-6.0-x86_64-netinstall.iso --os-type=linux --os-variant=rhel6 --disk vol=kvmguests/test --vnc -v --virt-type=kvm --check-cpu --prompt --arch=x86_64 Then I found out that I misconfigured vnc.

auth_ntlm_winbind_module causes 401 without any errors.
Hi, I am using samba 3.6.1 on centos 5.6, and joined a domain controlled by windows 2008. `ntlm_auth --username=magicloud` returns NT_XXXX_SUCCESS. So I assumed that everything is OK. Then I configured auth_ntlm_winbind_module for apache 2.2, which worked before with auth_kerb. LoadModule auth_ntlm_winbind_module /usr/lib64/httpd/modules/mod_auth_ntlm_winbind.so <LocationMatch

Interesting problem with write data.
Hi, Recently, I made a btrfs to use. And I met slowness problem. Trying to diag it. I found this: 1. dd if=/dev/zero of=test count=1024 bs=1MB This is fast, at about 25MB/s, and reasonable iowait. 2. dd if=/dev/zero of=test count=1 bs=1GB This is pretty slow, at about 1.5MB/s, and 90%+ iowait, constantly. May I know why it works like this? Thanks. -- To unsubscribe from this list: send the

Second VM cannot use the network.
Hi, I started to use libvirt and kvm yesterday. The first VM works great. Today I made another VM, same configuration as before. But its network just did not work. The guest cannot even get a dhcp ip. The network is NAT mode. The first VM got internal ip correctly. The command I made the VM is: virt-install -nzabbix1 -r2048 --vcpus=2
