Zlatko's questions

My specific use case is that I have a NetApp CIFS storage that's in the domain, say, intranet. But I also have one hyper-v host that's not in the domain. I can't allow it into the domain, but I need to create guests whose VHD is on the storage.

How can I achieve this? When I simply connect to a CIFS share and create a VHD there, it works, but when I try to add that VHD to the virtual machine, I get a "Failed to set folder permissions" error - probably due to folder ownership being in the domain admin.

Is there a way around this? So both domain and non-domain users use the same directory?

I'm wondering how to safely remove a domain user profile from a computer that is a part of a domain. I don't want to delete the account from the domain itself, I just need to remove the profile from this computer, to do some cleanup.

I'm currently on a Vista Business computer, but we also have Win XP Pro and Win 7 Pro.

Is it possible to install Host sFlow to Windows Server 2000 and Windows server 2003?

I've setup Ganglia on one host to monitor a (mostly Windows) environment and while sFlow works on Win 2k8 machines, it does not on my legacy servers. I just can't get the installation to do anything - when I start the installation, it immediately tells me that the process has prematurely ended.

Note: If sFlow can't work there, I'll accept an answer that suggests similar monitoring thingy that is willing to send data to Ganglia.

What are some of good ways to automatically monitor the size of files in a directory and send warning email if they get close to a certain limit on a Windows server?

I have a Progress DB installation to keep in check, and last week we hit some problems. Apparently, the size of extents has hit 2GB - and Progress won't work past that - we needed to open a new extent.

I'm coming from a Linux environment, so I don't know what are the usual to monitor this in a Windows environment (or monitoring tools whatsoever).

I prefer some generic solution, as I have a mixed environment (Windows 2000, Windows Server 2003, Windows Server 2008 R2).

Thanks in advance for all usable alternative answers.

I've recently found a referrer in the apache log on my site. Now, I opened it out of curiosity, since my site is live, but I just started development so I didn't expect it.

Anyway, the site was a pure copy of mine, and after investigation I saw that it resolves to my IP.

I'm on Ubuntu 12.04, Apache 2, drupal 7, don't know what other info can I provide.

My question is: how can I tell apache that it should not serve this site?

Thanks

Edit: forgot to say that I had some bots register to my fresh drupal installation. Also, my domain is a tld, this fake domain is a third level (ie. sub.domain.de)

I have 4 disks in 2 RAID1 mirrors on a Hewlett-Packard Company Smart Array. The OS is Ubuntu 10.04, cciss driver - so it's a hardware RAID We recently moved our office and the servers are in less then perfect conditions (no a/c, and with the summer temperatures, the fans work a lot).

Is there a way to monitor the temperatures or any other parameters on the disks/array?

I'm looking to replace my hard-drives with bigger-ones and I would like to know what are the best practices in doing this. I have a HP ProLiant with its 256MB version of RAID controller:

03:00.0 RAID bus controller: Hewlett-Packard Company Smart Array G6 controllers (rev 01)

I also have a pair of 10.000 rpm 146GB SAS drives in RAID 1. The OS is Ubuntu 10.04, 64-bit. I'm not using LVM.

We experienced a huge growth in content stored there and now I need to replace this array with another pair, 300GB disks. Ubuntu 10.04 is up there with a tomcat and a document management application (which is filling up most of the drive). I'm looking for the best way to do it.

I was thinking that I could do one of the following:

Option I: replacing a drive at a time. Basically, I'd do something like this:

1. Replace drive 1 with the new drive.
2. Rebuild the array to put the data on the new drive.
3. Replace drive 2 with the new drive.
4. Rebuild the array.

I don't like the two-times rebuilding part about it. I also don't know, if that would work at all and even worse, how much downtime is that. (around 115GB data, OS included.)

Option II: Create a new array. The idea here is that I would add the new disks and create a second array. I could then migrate my tomcat application to the new array - this would mean a simple cp operation.

I like this option much better, because it would also leave me the first array to use solely for the OS and I could do OS upgrades more easily in the future.

Is the option II doable at all? Where could I find some good resources on doing this whole procedure?

Are there other, better, smarter options I should try?

Thanks in advance.
