Troydm's questions

i'm running centos 5.6 as dom0 and want to install centos 5.7 as domu but every time i start installation the process stucks on "Starting install process.This may take several minutes..."

I install using network http method

I use xen boot images from http://mirror.centos.org/centos/5.7/os/x86_64/images/xen/

And i'm following this guide http://wiki.centos.org/HowTos/Xen/InstallingCentOSDomU

Here's my install config

kernel = "/srv/xen/install/centos-5.7/vmlinuz"
ramdisk = "/srv/xen/install/centos-5.7/initrd.img"
extra = "text"
name = "test"
memory = "512"
disk = [ 'tap:aio:/srv/xen/drive/test.img,xvda,w', ]
vif = [ 'bridge=xenbr0', ]
vcpus=2
on_reboot = 'destroy'
on_crash = 'destroy'

UPDATE*:

I've tested Centos 5.6 domu same thing

We have an oracle 11.2.0.1 server with 8 cores and 12gb ram. It's CentOS 5.6 and it has 12gb swap file. Oracle's memory target is 4gb and memory management is automatic. It has MegaSAS Raid controller with 4 drives.

Database itself is around 15gb with lots of blob data.

During sql selects server hangs a lot with high waiting for io, around 100%. It hangs in a way that I can't even connect to it using ssh. It eats around 5-6 gigs of swap. selects doesn't include blob data only plain rows.

I have vm.swappiness = 0 and I even tried swapoff but it still hangs.

What might be the problem?

I'm trying to configure a mirror for a Test database between two SQL Server 2008 R1 SP1 Servers: A1 and A2

I'm doing a full backup of Test database on A1 and then trying to restore it on A2 with NORECOVERY option but database stucks in Restoring... mode. I've also tryed using WITH REPLACE option but no use

What might be wrong? The database is only one table with one row, i don't have any transactions it's just newly created database

At home I have tomato usb installed on my Asus RT-N16, i want to block all traffic from host let's say 192.168.0.100 to host 192.168.0.200. both hosts are inside local lan network.

how do i do that with iptables?

i've tried

iptables -I INPUT -i br0 -o br0 -d 192.168.0.200 -s 192.168.0.100 -j DROP

but it's not working

I have a simple setup of netatalk afp server on my OpenSolaris box. And I also have samba on that box.

transfers from netatalk to my mac mini with Snow Leopard 10.6.8 go at speed 2-3 Mbytes/sec

but transfers from the same server using samba peak at 8-12 Mbytes/sec

Why do i have this huge difference? Am I missing something regarding afp config?

My afpd.conf looks like this

- -setuplog "afpdaemon log_info /var/log/afpd.log" -noddp -uamlist uams_dhx.so -nosavepassword

And this is my AppleVolumes.default

~ cnidscheme:dbd options:usedots,invisibledots,upriv perm:0770

netatalk is compiled using gcc 4.3.2 I don't have any tcp/ip tunes applied to my system it's just standart OpenSolaris 2009.06

I need a good terminal manager for Windows with ssh support that will have a fullscreen terminal mode so that i can switch to fullscreen and see only the terminal content without any toolbars etc.

I've tried Putty Connection Manager and mRemoteNG but they don't have this mode or am I missing something?

I have an Ubuntu server running gdm with graphical user session in it. I also have an open ssh console from remote host on that server.

I want to run x windows application from that remote console.

export DISPLAY=0.0 
xclock
Error: Can't open display: 0.0

How can i do that without restarting gdm and enabling remote connections with xhost +, is there any way? Can't i use local named pipes to connect to display server?

i have an iscsi target disk with only one ext3 partition on opensolaris using comstar

i also have two ubuntu instances with openiscsi initators that connect to that disk

both instances have this disk mounted (same disk is shared between instances)

when i write some data on instance1 on that disk i don't see any changes on that disk on instance2, maybe it's related to cache, if i remount the partition the changes are seen on instance2!

What might be the problem? Is it possible to use the same iscsi target disk shared between iscsi initiators?
