• How to use tscon on Windows7?

  - by Radek

  I need to run overnight automation testing using RFT and IE on Windows7 virtual machine. I found that restarting the Windows box before the testing starts helps. I am moving the production environment from Windows XP to Windows 7. RFT used to complain when running RFT scripts that CRFCN0557E: Activation failed when running under a Terminal Services environment. This may be caused by using a minimized terminal window - try playing back without minimizing the terminal window (it does not need to be full-screen). Running tscon.exe 0 /dest:console prior starting any RFT script fix the error on Windows XP. But not on Windows7. I did some research and was trying for hours to fix that but nothing helped. There is no screen saver turned on on Windows7. I tried to run both but nothing helped. tscon.exe 0 /dest:console tscon.exe 1 /dest:console On Windows7 tscon returns {ErrorPrintf(): LoadString failed, Error 15105, (0x00003B01)} Error [15105]:The resource loader cache doesn't have loaded MUI entry. Error [0]:The operation completed successfully. On Windows XP tscon returns Could not connect sessionID 0 to sessionname console, Error code 7045 Error [7045]:The requested session access is denied. I just double checked that running tscon.exe 0 /dest:console on Windows XP solves the issue. Cannot understand the output of the tscon command then. Any idea how I can run RFT scripts after I restart the Windows box automatically? Preferably without involving any other computer. I was even thinking to use the old Windows XP to make remote desktop session to make RFT happy. I hope there is other better solution to that.

• SQL Server 2008 Cluster Installation - First network name always fails

  - by boflynn

  I'm testing failover clustering in Windows Server 2008 to host a SQL Server 2008 installation using this installation guide. My base cluster is installed and working properly, as well as clustering the DTC service. However, when it comes time to install SQL Server, my first attempt at installation always fails with the same message and seems to "taint" the network name. For example, with my previous cluster attempt, I was installing SQL Server as VSQL. After approximately 15 attempts of installation and trying to resolve the errors, e.g. changing domain accounts for SQL, setting SPNs, etc., I typoed the network name as VQSL and the installation worked. Similarly on my current cluster, I tried installing with the SQL service named PROD-C1-DB and got the same errors as last time until I tried changing the name to anything else, e.g. PROD-C1-DB1, SQL, TEST, etc., at which point the install works. It will even install to VSQL now. While testing, my install routine was: Run setup.exe from patched media, selecting appropriate options After the install fails, I'd chose "Remove node from a SQL Server failover cluster" and remove the single, failed, node Attempt to diagnose problem, inspect event logs, etc. Delete the computer account that was created for the SQL Service from Active Directory Delete the MSSQL10.MSSQLSERVER folder from the shared data drive The error message I receive from the SQL Server installer is: The following error has occurred: The cluster resource 'SQL Server' could not be brought online. Error: The group or resource is not in the correct state to perform the requested operation. (Exception from HRESULT: 0x8007139F) Along with hundreds of the following errors in the Application event log: [sqsrvres] checkODBCConnectError: sqlstate = 28000; native error = 4818; message = [Microsoft][SQL Server Native Client 10.0][SQL Server]Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'.

• Dell Perc 6i with FreeBSD 8.1 errors with mfi0: COMMAND xxxxxxxx TIMEOUT AFTER xxx SECONDS

  - by jDempster

  We've recently bought two Dell PowerEdge R710 servers with Perc 6i controllers and 6x 135GB SAS Drives. We'd done some pretty extensive testing on a Dell PowerEdge R510 server with a Perc 6i and 4x 135GB SAS Drives running FreeBSD 8.1 for it's wonderful ZFS support and mfiutil. We hadn't had any problems with the R510 and had got to a point where we where happy with the performance of ZFS. Since running FreeBSD 8.1 on the R710 we've been getting errors from the RAID controller. mfi0: COMMAND 0xffffff80005d1770 TIMEOUT AFTER 6178 SECONDS This usually brings the system to a stand still. But it doesn't always happen, and performs very well up until it does happen. We've been running the disk as 3 mirrored drives striped in ZFS. So far we've noticed that running the drives with RAID10 on the RAID seems to work without errors (still testing). At first I thought hardware error as we'd been running FreeBSD on the R510 with the same controller without any issues. But both R710 have the same issue. All controllers are running the same firmware.

• How to actually defragment a JFFS2 filesystem

  - by Julie in Austin

  I have searched all over the Internet, including on a number of StackExchange forums, for a workable method for defragmenting a JFFS2 filesystem and cannot find an answer. The system in question has a 256MB NAND flash part. It is being accessed as a MTD device which is divided into three partitions. The third partition is where the root file system is being stored as a JFFS2 file system. The issue is that writes to the root file system have non-deterministic performance due to the usual issues of the JFFS2 garbage collector deciding to run at the worst possible times. When that happens, the product is hung for some unknown length of time while the garbage collector (and pdflush) run. Changing the file system isn't an option. The solution needs to be something that can run during off-hours that after having been run results in more predictable write performance. Right now I am working on a program that will attempt to force the garbage collector to run, then delete the file with the hope that all of the freed nodes are suddenly more readily available and make writes perform better. Thoughts?

• Prosody mod auth external not working

  - by Yang

  I installed mod_auth_external for 0.8.2 on ubuntu 12.04 but it's not working. I have external_auth_command = "/home/yang/chat/testing" but it's not getting invoked.

• Windows Server 2008 Stops Responding (Hyper-V Role Enabled)

  - by blackf0rk

  The machine is a brand new Dell Precision m6500, Core i5, 8GB RAM. Windows Server 2008 R2 (fully patched) with Hyper-V Role Enabled. Virtualization options in the BIOS are ON, SpeedStep is OFF, couldn't find C1E option in the BIOS to turn it off (I also got the impression that SpeedStep is C1E, but the Intel Product site lists them as separate "features." shrug) The server stops responding without any apparent reason. I've tried testing in multiple scenarios, all of which result in a crash at seemingly random times: With the Server sitting idle, no apps running. Server sitting idle with a Virtual Machine running. Using a BurnInTest application There's no blue screen. It doesn't restart. The screen just sits there. The keyboard backlight still responds and comes on with input, but nothing on the screen changes. There are no errors in the error log. I have to hold down the power button to turn it off. Doing memory tests on bootup results in no errors with the memory. I have a second identical system and the same thing happens there too. I've dual-booted into Windows 7 Profession x64 on this system with no problems. Further testing has shown that the issue is definitely related to Windows Server 2008 R2 and Hyper-V as it appears the crashing does not happen when the services are not running. I've installed all hotfixes relating to this issue (that I could find): 975530, 979444, 979491, 976427 System is still crashing without response.

• snmpd dead but subsys locked

  - by Hina NMS

  Hi folks I have an NMS and a Client machine. I want the client to send traps to the NMS. I have been configuring the snmpd.conf file testing if i disable a process do i receive an alert or not. For the changes to reflect that were made in the conf file i restarted the snmpd daemon each time. The testing was going fine. All of a sudden when i restarted snmpd i recieved the error msg "snmpd dead but subsys locked". I googled for answer as to what it actually meant and found out that when a service is started a logfile is created in the /var/lock/subsys. Sometimes if the service is not stopped properly or whatever the logfile remains created. Though i started/stopped the snmpd service properly it didnt go away so i removed the file manually (via rm cmd). when i checked the status the error "snmpd dead but subsys locked" was gone. On my NMS i recieved the alert of snmpd coldstart. i started the snmpd service everything goes fine! BUT after 5 mins again i recieve the same error message and this keeps on happening..what do i need to do now?

• cPanel web servers mounting home partition to a NAS or SAN

  - by Scott

  Hello, I currently have 2 cPanel web servers that are little 1RU dual cpu quad core xeons. They have a lot of resources for processing and handling web requests, and never exceed more than 10% cpu usage. They also have plenty of RAM. The problem is though that they both have RAID 1 160Gb SAS hard disk drives in them that are 75% full, and growing by the day. I didnt think that the amount of disk usage would be so high, but due to the nature of the sites hosted, this has become an issue. The easy fix would be just to upgrade the hard drives to something bigger (probably not of the SAS variety), but I am thinking of keeping the current machines as "processing servers" and buying a central "storage server" with about 12TB of storage. The /home/ partition on each of the 1RU servers would be mounted to a NAS or SAN point on this central storage server. My questions are: - Has anyone got a cPanel setup where they mount /home/ to a NAS or SAN elsewhere? If so, can you provide details as to what you did and how it went :) - Any recommendations on networking? Is gigabit ethernet enough? Is TCP/IP going to be a noticable performance problem? Anyone used a TOE key? - Anyone benchmarked or had any performance issues with SAN over NAS? Any help greatly appreciated. Scott

• Antivirus Configuration for dedicated SQL and dedicated IIS Servers

  - by Wayne Arthurton

  Our corporate standard is McAfee Enterprise, unfortunately this is non-negotiable. On two types of servers I'm responsible for, SQL & Web, we have noticed major performance issues with the corporate standard setup. Max scan time 45sec One policy for all processes Scan ALL files on write, read and open for backup Heuristics: Find unknown programs, trojans and macros Detect unwanted programs Exclude: EVT, LDF, LOG, MDF, VMD, , windows file protection) This of course still causes major slowdowns. IIS .NET recompiles are slow especially with SharePoint, SQL backups and restores, SQL Analysis Services, Integration Services and temp data from them as well. I have looked from time to time, for some best practices on setting up McAfee of SQL & SQL Analysis Service, SQL Integration Service, Visual Studio, Sharepoint, and .NET web servers in general. How do people setup McAfee enterprise on their corporate serves keeping security intact, but affecting performance as minimally as possible? Has anyone run across white papers on these setups? Obviously some are case by case, but there must be some best practices out there somewhere.

• Cannot delete old NFS directory: Device or resource busy

  - by Jakobud

  On server1, we had an NFS share mounted from server 2 like this: /nfs/server2/share Recently, we took down server2 to install a new OS on it. Now we can't get NFS setup the way it was. When I do this: ls -l /nfs I get this: drwxr-xr-x 2 root root 0 2010-03-15 09:59 server2 Notice how the directory size is 0 instead of 4096 like usual? Anyways I go into server2 expecting to see a share directory, but I don't. It's empty. So therefore I cannot mount my share at /nfs/server2/share. When I try to create /nfs/server2/share directory, I get mkdir: cannot create directory `share': No such file or directory I think this is because it doesn't really think the /nfs/server2 directory really exists. Even if I use the -p option with mkdir, it doesn't work. Next I tried to remove /nfs/server2 so I could just recreate it. I try to rm -r /nfs/server2 but I get rm: cannot remove directory `/nfs/server2': Device or resource busy So now I'm at a loss. I need to mount this NFS share in the same exact place on server1 (at /nfs/server2/share) because other software on server1 depend on this. But if I can't create that share directory and I can't remove that directory, what do I do? Also, just for testing, I attempted to mount the share at /nfs/testing/share and it mounted just fine. But like I said, I need to mount it back in the same location.

• Dell Management Packs in System Center Operations Manager 2007 R2?

  - by bwerks

  Hey all, I recently set up SCOM in a small business network environment. The root management server is a Dell Poweredge 2950, and I'd like to use SCOM to monitor it using Dell's management packs. I've imported the management packs into the SCOM deployment and followed Dell's installation instructions, but it doesn't seem to be fully working yet. Currently, the Diagram views in the Dell tree (Monitoring tab) seem to show me the server's place in the network topology, so it seems that at least part of it is working. However, none of the reports under "Performance and Power Monitoring Views" provide any information. When clicking on one of them (Power Consumption (Watts), for instance), the display area is blank and there is a tooltip visible that reads "No performance counter is selected. To select a counter, place a check mark in the Show column in legend below." However, in the legend, there's nothing there for me to check. I've installed OpenManage 6.2 on the server as per the Dell documentation, but I don't know what else I could have done that I missed. Does this sound like a familiar problem to anyone?

• zfs setup question

  - by Staale

  Currently I have a linux storage box and server with 4x750gb harddrives in raid-5 with ext3. I have ordered 3x1.5tb disks to upgrade this. Here is my planned upgrade: Backup: Format the 1.5 tb disks Copy all data from the raid-5 disks to the 1.5tb disks Destroy the raid-5 array. New setup: Create a VirtualBox system and install Nexenta (OpenSolaris + ubuntu) on it. Create a zfs pool with zraid1 with the 4 750gb disks. Copy from 1.5tb disks to the virtualbox zfs pool Format the 1.5tb disks. Replace 3 off the 750gb disks with 1.5tb disks. Reuse the 750gb disks elsewhere. The reason I wish to use one 750gb disk is since I can't grow the disk count in a raidz array, and this gives me the option off replacing that disk later for an extra 750gb storage. Would the ZFS performance be good running through virtualbox? Or will the performance overhead be too large? Will I get 1.5tb+1.5tb+750gb storage on the zraid? Or just 750gbx3 until all disks are 1.5tb?

• Developer's PC - worth getting more than 8GB RAM?

  - by Borek

  I'm building a developer PC and am wondering whether to get 8GB or 12GB. It's a Core-i7 860 system, i.e., 1156 motherboards with 4 slots for RAM sticks, dual channel, usually up 16GB (as opposed to 1366 sockets where 6 banks / triple-channel are used). 8GB would be cheaper to get especially because price per GB is lower with 4x2GB compared to 2x4GB. Also the availability is worse for 4GB DIMMs here where I live; those are the main practical advantages of 8GB. (Edit: I should have stressed the price difference more - in the eshop I'm buying from, the difference between 12GB and 8GB is so big that I could almost buy a whole new netbook for it.) However, I understand that more RAM can never do harm which is the point of this question - how much of a difference will 12GB make as opposed to 8GB? Honestly, I've always been on 3.2GB systems (4GB but 32bit system) and never felt much pain from having too little memory - of course there could be more but for instance compiler's performance was usually held back by slow I/O or not utilizing multiple cores on my CPU. Still, I'm not questioning that 8GB will be useful, however, I'm not sure about the additional 4GB difference between 8 and 12 gig. Anyone has experience with 8GB / 12GB systems? The software I usually run all the time: Visual Studio or Eclipse (both should be fine with ~2GB RAM, after that I feel their performance is I/O bound) Firefox (it can never have enough RAM can it? :) Office (~500MB RAM should be enough) ... and then some smaller apps like Skype, other browsers, some background services etc.

• ZFS - zpool ARC cache plus L2ARC benchmarking

  - by jemmille

  I have been doing lots of I/O testing on a ZFS system I will eventually use to serve virtual machines. I thought I would try adding SSD's for use as cache to see how much faster I can get the read speed. I also have 24GB of RAM in the machine that acts as ARC. vol0 is 6.4TB and the cache disks are 60GB SSD's. The zvol is as follows: pool: vol0 state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM vol0 ONLINE 0 0 0 c1t8d0 ONLINE 0 0 0 cache c3t5001517958D80533d0 ONLINE 0 0 0 c3t5001517959092566d0 ONLINE 0 0 0 The issue is I'm not seeing any difference with the SSD's installed. I've tried bonnie++ benchmarks and some simple dd commands to write a file then read the file. I have run benchmarks before and after adding the SSD's. I've ensured the file sizes are at least double my RAM so there is no way it can all get cached locally. Am I missing something here? When am I going to see benefits of having all that cache? Am I simply not under these circumstances? Are the benchmark programs not good for testing the effect of cache because of the the way (and what) it writes and reads?
