When updated VMware ESX 4.0 to 4.1:
Host was not updated, no changes required.
Skipping bulletin ESX410-GA-esxupdate; it is installed or obsoleted.
Encountered error RunCommandError:
This is an unexpected error. Please report it as a bug.
Error Message – Command ‘[‘/usr/bin/vim-cmd’, ‘hostsvc/runtimeinfo’]’
terminated due to signal 6
Simply type: ldconfig
[ad#Google Adsense]This error will appear when attempting to install VMware vCenter 4.1.
A work around for this issue is to create a system DSN.
Then open regedt32 on the server and go to HKLM > Software > ODBC.INI >
Update its driver to: C:WINDOWSsystem32sqlncli10.dll.
Restart the vCenter install.
psql
With psql cli:
vacuum full;
also do:
reindex
When running VMware PowerShell CLI you receive this error:
Set-ExecutionPolicy : Access to the registry key ‘HKEY_LOCAL_MACHINESOFTWAREMicrosoftPowerShell1ShellIdsMicrosoft.PowerShell’ is denied.
Right click powercli and click: “Run As Administrator”
Once powershell starts type this command:
Set-ExecutionPolicy RemoteSigned
List off all the rules in order. This helps to see if an allow is overriding one of your denies:
iptables -nvL –line-numbers
Reject or Drop?
Drop means to drop everything at the interface and give no response. Best for port probes and the like.
Reject responds to the source. Best practices for TCP/IP
Mon Nov 29 17:38:05 PST [raid.assim.disk.nolabels:error]: Disk 0b.18 Shelf 1 Bay 2 [NETAPP X274_HPYTA146F10 NA03] S/N [V5Y692RA] has no valid labels. It will be taken out of service to prevent possible data loss.
You will receive a message similar to the above on the simulator.
Type these commands in the shell:
priv set diag
disk unfail -s v4.29
This is scumbag malware designed to take your machine hostage until you pay.
Here is the -quickest- way to eliminate this tediosity:
1. Register the scumware using this serial number: SL55J-T54YHJ61-YHG88
Once this is done it will allow you to now use your computer.
2. Open explorer and delete: C:Documents and SettingsAll UsersApplication Datadefender.exe
If the file is not there, search for: defender.exe and delete it.
3. Download SpyBot Search & Destroy and run it on your machine: http://www.safer-networking.org/en/download/
AMD64 Kernel FreeBSD machines are good about autotuning. i386, on the other hand, needs to be adjusted manually.
1. Rebuild your kernel
a. Disable/wipe all drivers you are not using or at least those you are highly unlikely to ever use.
b. Add: options KVA_PAGES=512
c. Recompile/Install new kernel
2. Add these parameters to /boot/loader.conf
a. vm.kmem_size=”1024M”
b. vm.kmem_size_max=”2048M”
c. vfs.zfs.arc_max=”256M”
d. vfs.zfs.vdev.cache.size=”40M”
This will get the machine online without it crashing with vm.kmem errors. ZFS will bring an untuned i386 machine down to its knees with kernel panics quickly!
Adjust the above variables to your tastes. My test platform is a Dual Xeon with 4GB of RAM.
This is what your rc.conf should contain to configure LAGG with FreeBSD:
### LAGG NFS Interface ###
ifconfig_bce3=”mtu 9000 up”
ifconfig_bce0=”mtu 9000 up”
cloned_interfaces=”lagg0″
ifconfig_lagg0=”laggproto roundrobin laggport bce3 laggport bce0″
ipv4_addrs_lagg0=”10.10.40.10/24″
Change the bce* interfaces to whatever your server is using for the network interfaces.
The “mtu 9000 up” is correct!
This script will replicate a ZFS pool to another FreeBSD machine. The sync process is quick, after the initial copy, and depending upon how much data changed.
Download this shell script: http://www.tediosity.com/zfsrep.sh
This script was written by another author for Solaris and I have fixed it to work on FreeBSD.
I chose to use: /root/zfsrep as the script location.
mkdir -p /root/zfsrep/zfsrep.snapshots
touch /root/zfsrep/zfsrep.log
cp zfsrep.sh /root/zfsrep/
vi zfsrep.sh and modify the e-mail address and location of the script (if you are not using /root/zfsrep)
Initial run:
/root/zfsrep/zfsrep.sh sinit nfs/datastore nfs/datastore 10.10.30.20
Subsequent runs:
/root/zfsrep/zfsrep.sh sync nfs/datastore nfs/datastore 10.10.30.20
Create a cronjob and forget about it.
If you make any changes, error fixes, or enhancements please e-mail them to me!! I love seeing other people’s creativity and putting their ideas to work in a production environment.
