My QNAP storage got a failed drive (drive 1 to be specific). I pulled it out, inserted a new one and… nothing happened. On the web console it was showing RAID 5 Disk Volume with only drives 2, 3 and 4. The volume had “degraded” status and the Action button was greyed out. Here’s the solution:

It has been always a problem to match LUNs on ESX to LUNs on a storage. Eventually I wrote a short script to make this work way easier
Honestly speaking I do not know when exactly it happened and why, but one day I found out that the Windows Firewall service on my computer was stopped. Not a big deal, I tried to start it up and got the Access Denied error. Read the rest of this entry »
