After configuring LAGG (Failover) your NAS4Free instance is not reachable.
This can happen if you assigned an ip address to a network adapter (bce0, bce1, …) prior you switched to LAGG. You can simply fix this by opening /etc/rc.conf and removing all assinged ip addresses to single adapters.
Remove ipv4_addrs_bce0=”0.0.0.0/0″, … and reboot. Thats it.
I was trying to install NAS4Free (FreeBSD) on a HP ProLiant DL380G7. I entered Configuration Utility for the RAID Controller (HP Smart Array P410i) and removed all logical drives, as there is no need for a hardware raid if you’re going to use ZFS. I assumed no logical drives = JBOD but I was wrong.
The HP Smart Arry P410i does not support JBOD Configuration. HP seems to be aware of this so they created a…hmm… kind of a workaround. Simply boot up the latest smartstart package and start the smart storage configuration utility. In there you can create an array with RAID0, there is even a button for it.
Press “Create Array with RAID 0”.
Select all available disks.
After that you created a RAID0 on each physical drive.
Thats it. Its no pass-through but works like jbod.
Good luck.
Installing the Workflow Manger 1.0 Refresh can be tricky.
During Installation process with the web platform installer 5.0 (only way to install it) the setup of Microsoft Windows Fabric V1 CU1 fails. When you open the log it says 1603.
So lets see what 1603 means. Open cmd prompt and type net helpmsg 1603.
C:\>net helpmsg 1603
Fatal error during Installation.
Not very expressive. But there is a simple solution, install Visual C++ Redistributable for Visual Studio 2012 Update 4.

After installing Windows Server 2012 R2 or Windows 8.1 you will be asked if this is a home/work network or not. Based on that windows will choose your network profile.
I was some kind distracted and accidently clicked in the middle of the desktop and the sidebar disappeared. Windows decided that this is a “No” and you will be on a public network. I’ve no idea why but you can not change it through the network and sharing center, all settings you’re trying to set will be set back to default of public networks. Like network discovery. So how to change it? Quite easy, just open the registry and navigate to the following path:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\NetworkList\Profiles
There will be at least one key in that list. Simply delete the one you want to reset and reboot your machine. After that you will be asked again. However I would only recommend that method if that happened to you right after the setup as I don’t know if some firewall rules will be reset or deleted.
I’ve tried to install some machines on my Hyper-V. All ISOs were placed on the second drive where data deduplication is enabled. With deduplication enabled I ran into the problem that no serial/license number was accepted neither the AVMA Key nor the generic KMS Key or my own key. After hours of searching for solutions on the web and no solution in sight. I copied the iso to drive D again. Suprise it was working! One day later I tried to install a new machine and it wasn’t working again. No key accepted. After moving it to drive C where no deduplication happens its working again.
Conclusion: Never ever put windows installation media on a drive with data deduplication enabled.
I’ve rented a lot of linux vps around the world for testing and hosting teamspeak and other stuff. Not every application runs on linux so I decided to build a small home server with a low power consumption.
I stumbled over the list of components in the hardwareluxx forums and build my system based on that components. ( Link )
Here is my list:
First of all I removed the Mini PCIe Wifi card from the mainboard as its not needed and plugged in the mSATA at the bottom of it. The small SSD can be used for the OS (Server 2012 R2) or as Host Cache for ESXi.
After putting all components together I enabled all bios settings allowing power savings and switched of the soundcard etc. I also tried to undervolt the CPU with the VCore Offset and got it down to -0,235mV.
Here are the results (power measurement):
| ESXi 5.5 U1 | Windows Server 2012 R2 | |
| Idle | 18.2 Watts | 11.1 Watts |
| Load | 39.6 Watts | 35.8 Watts |
Make sure all drivers are installed and no usb devices are plugged in. The usb devices may prevent reaching a package c-state of more than 80.
The network drivers are a little tricky. For ESXi 5.5 follow this guide ESXi 6.0 includes drivers for Intel I217V and for Server 2012 follow this guide.
Good luck and post your results.
As I’m to lazy to add a floppy drive to my VMs for adding the pvscsi drivers, I created an ISO from pvscsi-Windows2008.flp.
Simply dismount the windows install disk, mount pvscsi-Windows2008.iso, select the drivers and remount the windows install disk.
Download from here: pvscsi-Windows2008.iso
Recently I stumbled over out ULS Logs on the Web Frontends. Suprisingly they were empty, 0 bytes. I checked the permissions for the account the tracing service is running with (Web Application Pool Account). Everything was fine, same permissions as on the other servers where it was working.
So I checked the local groups and found out the tracing account must be a member of the “Performance Log Users”. Add the account, restart the “SharePoint Tracing” Service and you will see the uls logs growing.
We had the problem that our data warehouse can’t process all performance data being collected. To get rid of this problem you need to disable some performance collection rules in your opsmgr 2012r2 (preferable the ones you don’t need).
You may find out which one collect most data you can run the following queries against your dwh.
Performance insertions per day
SELECT CASE WHEN(GROUPING(CONVERT(VARCHAR(20), TimeSampled, 102)) = 1)
THEN ‘All Days’ ELSE CONVERT(VARCHAR(20), TimeSampled, 102)
END AS DaySampled, COUNT(*) AS PerfInsertPerDay
FROM PerformanceDataAllView with (NOLOCK)
GROUP BY CONVERT(VARCHAR(20), TimeSampled, 102) WITH ROLLUP
ORDER BY DaySampled DESC
To find the rules collecting the most Performance Signature data in the database
select managementpack.MPName, ruleview.DisplayName,
count(*) AS TotalPerfSig
from performancesignaturedata with (nolock)
inner join performancesignaturehistory with (nolock)
on performancesignaturedata.performancesignaturehistoryid = performancesignaturehistory.performancesignaturehistoryid
inner join performancesignature with (nolock)
on performancesignaturehistory.performancesignatureid = performancesignature.performancesignatureid
inner join ruleview with (nolock)
on ruleview.id = performancesignature.learningruleid
inner join managementpack with(nolock)
on ruleview.managementpackid = managementpack.managementpackid
group by managementpack.mpname, ruleview.Displayname
order by TotalPerfSig DESC, managementpack.mpname, ruleview.DisplayName
Good luck
After a major network outage one of our server doesn’t want to connect to the database server anymore. The event log was spammed with the following message:
Error 07.01.2014 10:09:09 Microsoft-SharePoint Products-SharePoint Foundation 5586 Database “Unknown SQL Exception 64 occurred. Additional error information from SQL Server is included below.
A transport-level error has occurred when receiving results from the server. (provider: TCP Provider, error: 0 – The specified network name is no longer available.)”
This message only appeared on one out of five servers. No reboot, no iisreset resolved the problem.
We resolved the issue by moving the database to another sql node (FailOver / Always On). When you move the database all connections will be forcibly closed. Seems that the sql server doesn’t allow the server to connect to the database as some connection was still established. If you can’t move the database to another node, simply restart the instance or put the affected database in single user mode to close the connections.
