TweetLinux supports hot-adding disks but whenever I add a new vdisk in VMware the new disk doesn’t show up unless I reboot, which defeats the purpose of hot-add. This command forces a rescan of the bus: echo "- – -" > /sys/class/scsi_host/host0/scan dmesg shows the new disk has been found: Vendor: VMware Model: Virtual disk [...]
TweetAfter my recent wipe of my laptop, I reinstalled VMware Workstation and my Win XP VM was working fine. The one wrinkle I faced was that the subnet for the vmnet8 (NAT) vnic had changed from 192.168.250.0/24 to 173.16.132.0/24. The host machine had been 192.168.250.1 so rather than reconfiguring everything on the guest to point [...]
TweetThis turned out to be so ridiculously easy I probably shouldn’t even mention it, but only because I remembered that Update Manager exists. I thought I was going to have to burn an ISO, go to the datacenter, pop the disc in, etc. But with Update Manager this is all handled remotely. Just download the [...]
TweetI’m into my second day on this project. It appears that the backup and restore procedures run to completion but on the target machine the database is empty. This is pretty easy to check; I just went in with SQL Management Studio, looked in VIM_VCDB -> Tables -> dbo.VPX_DATASTORE and did “Open Table.” On the [...]
TweetWhen vSphere 4.1 was released earlier this year, I was mildly excited. Our ESX servers are still running 4.0.0 and I had been planning to upgrade to 4.0u1 for a while. When 4.1 came out it seemed to have vindicated my procrastination: now I could just upgrade to 4.1 and take advantage of whatever new [...]
TweetWhen I started at my current company, spam was handled with a separate server running SpamAssassin and a few other services. This sort of got the job done but required babysitting. I wasn’t part of the Sysadmin team at that point but I know they had to restart SpamAssassin relatively frequently, manually clear out the [...]
TweetI started migrating our physical machines to VMs using VMware a few years ago and the first problem I ran into is still the most annoying one: the size limit for LUNs is, per VMware’s docs, (2TB – 512B). That’s 512 bytes shy of 2TB, so basically 1.99999 TB, or 2047.999 GB. So when I [...]
