Sväng med Model 3 Performance mellan Östra Forestad & Perstorp
In a previous article I migrated my system to root on ZFS, that it also boots from.
When I did that the recommended size was 64K, however with FreeBSD 11 that is too small so to be able to upgrade I need to increase it in size.
I’ve seen some articles say that you need to remove and recreate the pool to do it, but I figured there must be an easier way…
I found plenty of posts with scripts that automated the firmware upgrade for UCS servers running VMware ESXi. I did however not think they were “safe” enough, so I wrote my own.
It will update the firmware of all the hosts in the specified cluster, one host at a time.
It requires UCS Powertool 2.x and VMware PowerCLI 6.x. It logs the relevant steps with time stamps, so you’ll know whats happening.
It does the following:
1. Get the ESXi-hosts in the cluster to work in.
2. Dismounts VMware tools(would prevent putting a host in maintenance mode) on VMs running on the host.
3. Takes the first(added to the cluster, not name) host and puts it in maintenance mode.
4. Records the MAC address of vmnic0 for that host.
5. Shuts down the host.
6. Checks in UCS Manager which Service Profile matches that MAC address.
7. Verifies that the matching server is powered off.
8. Applies the firmware policy specified.
9. Acknowledges the reboot.
10. Waits until the server operational states goes from “config” to “ok”.
11. Waits for the server to reconnect in vCenter.
12. Exits the host from maintenance mode.
13. Repeats the process from step 2 with the rest of the hosts in the cluster.
Like many others, it seems, I got the dreaded “mosh-server needs a UTF-8 native locale to run.” when trying to use mosh from my OSX laptop to my FreeBSD server.
I tried the stuff google suggested, but nothing worked. What eventually solved the problem for me was adding the following to .bash_profile on my OSX client:
My old Core 2 Duo server from 2007 has been with me for a little too long now. Its an old workstation from a previous job. But I haven’t really found any alternatives that fit both my requirements and budget, until now.
My requirements were a passively cooled(low TDP) mITX board with an integrated CPU(with decent performance), at least 4 SATA ports, an HDMI port and DDR3 SO-DIMM slots. For no more than about 80 USD. Until Intel released the Bay Trail CPU family there was nothing that could fill those requirements. So when I saw that Asrock released their Q1900-ITX board, I ordered one.
Bleeding edge hardware and FreeBSD requires some tweaking though…
Here I will post ipk packages of telldus-core built for various OpenWRT architectures(they are built for Attitude Adjustment 12.09). I have detailed how to build it yourself in a previous post, but it is a bit complicated to do. Especially if you’re not used to compiling stuff, or Linux at all. So the packages below can simply be SCP’d to your router and then installed by running: Continue reading
If you have a Dovado router you can supposedly plug in a Tellstick from the get go.
But for any other router, some work is required. This is another post mostly for my own reference, but hopefully it’ll be useful for you too.
First of, you should install OpenWRT on your router(it obviously needs to be one with a USB port). That way you can build and install whatever software you want. And since Telldus provides a source package that you can compile, that makes it a lot easier.
Tried installing EMC SRDF SRA 5.1 on my new VMware Site Recovery Manager 5.1 server. It installed fine, but apparantly didn’t create an EMC Symmetrix folder under the sra-folder as it should. After a bit of googling and searching the forums on Powerlink I gave up and contacted EMC support. Turns out it currently doesn’t work when SRM is installed somewhere other than C: and they had no solution to it.
