Backup, backup, backup. During my stay away, one of the drives of one of the nodes in my cluster failed. The problem is that it was an half backed failure, with sporadic failures leading to corruption. So, I lost my ability to communicate by emails during the last 3 weeks. Not fun because from my point of view I was able to send the emails, but most of the emails ended up in a computer black hole.
If you communicated with me during the last 3 weeks by email, please accept my sincere apologizes. If you do not get an answer to your inquiry within about 8 days, please send your email again, my emails are hosted by an independent provider, but the DNS server is hosted on the cluster, so the hard drive failure may have affected DNS resolution and thus email transfer.
Everything should be back to normal by Friday the 6th of September.
