In our project to migrate all our servers from our old SAN and VMware environment to our brand new top of the line EMC VNX VPlex SAN and new Dell VMware-hosts, we only have one server left, the server that hosts the home directories for all our users(except students). In our old environment we have an 12 terabyte raw device mapping, so the only way to migrate it with VMware is by cold migration and approximately 48 hours of down time. we also wanted to shrink it and convert it to a vmdk instead of an rdm. We decided to create a new vmdk-disk and use robocopy to copy all the files, doing so we reduce downtime for our users and gets a new smaller disk. Robocopy don´t copy folder quotas and we have pretty complex quota structure with individual quotas on each users(about 8000) home directory, therefor me and my college Stefan Lozancic created a script to that migrates all quotas to the new disk.

Today I got a case from a user who wanted to know which directories that would be effected if he deleted a security group. This is a typical case that that often end up on second or third-line, therefor I wrote a function so that help-desk easily can do it the next time a user adds a similar case. First it lists all sub directories of the path specified, it then uses a foreach loop to find out if the object specified exists in the IdentityReference property and list the pspath. since pspath includes “Microsoft.PowerShell.Core\FileSystem::” when you try to export to csv i had to do a replace with nothing to get a clean path. when trying to replace i got an error “The regular expression pattern”…”is not valid” since there is a “\” and -replace parses the string as an regular expression you need to escape it by putting another “\” in front of it. I made the export to file so my colleagues would get a file to mail to the user.

Last friday me and my girlfriend finally decided a hotel and date for the summer holiday. She had found a hotel to reasonable price at the travel-agent solresor. I told her I just had to eat and would book the trip right after lunch. When I came back the hotel was sold-out at the date we had planned for. I called the travel-agent and asked if they had any notification-service, if someone would cancel their trip, unfortunate they had no such service and they told me to check their website manually to see if the hotel would reappear. Since I am lazy and didn´t want to manually check their website a built a script to do it for me.
I found out that on step 4 in their booking the website created an unique URL with hotel short-name and departure date, if I used that URL I would get an answer with body if the hotel and date were available and I would get an empty answer if the date was sold-out.
So I made a script that checked the URL once every minute and would send me an email if the URL existed. Unfortunately the hotel never showed up, but it was fun to create the monitor.
