Some more Openfiler
Thursday, May 30th, 2013 | Author: Ozzik

Heeeey….
It’s been almost two years since I wrote the last time. I guess I had nothing to say until now;)
No, that’s not true, just didn’t have the time or the energy.
But the last couple of days pushed me towards posting some more about Openfiler.

This project is quite controversial. On one hand, it’s good. It combines most of the features, stability and quality you want for the storage without paying a cent.
On the other hand, the dev team is odd. To say the least. Their thing is that they don’t talk to the users. They used to, but they don’t anymore.
They had promissed to release the version 3.0 about 3 years ago, since then they keep it silent.
Now, I totally understand the “it’ll be released when it’s ready” attitude, a lot of open source (and only) projects do that. But at least talk to your community, tell them approximately what’s going on, something.
A lot of people just said goodbye to the project because of this. But it doesn’t seem to effect the principle - to disregard the community.

Anyway, personally, when choosing the storage for the mid-size company I’m still choosing the OF, because I know it pretty well, it proved to be stable enough and it has all the features a company may need.

DNS resolving in Openfiler
Thursday, August 04th, 2011 | Author: Ozzik

Just a small issue I had today.
Since I run rsync scripts at night and get email about their execution, I noticed that email came with:

ssh: Could not resolve hostname SERVERNAME: Name or service not known
rsync: connection unexpectedly closed (0 bytes received so far) [receiver]
rsync error: unexplained error (code 255) at io.c(635) [receiver=3.0.3]

Backup via rsync
Monday, January 05th, 2009 | Author: Ozzik

Hi again,
after a long New Year’s break, I’m back to deliver the promised procedure of backup via rsync when working with Openfiler.
In the previous post I described the hardware situation in our company, so it should be clear by now that I have two Openfiler machines: one in production, and another one in standby.
Before I get into the details, I wanna tell you about some things you may want to consider.

The Openfiler is actually able to do the DRDB, which is a High Availability setup, when the production machine is replicated online to the backup one. Each of them has an IP, plus they have another virtual IP that they pass on to each other in case of failure. The users (and the DNS) actually work with this VIP. So any failure is actually transparent to everybody. It’s a standard HA setup. The only thing I asked myself is what happens if you accidentally delete a file? If it’s going to be replicated immediately to the other machine - what’s the point of having a backup? Actually, I believe I’m not the only one who’s asked that question, so it’s very possible that there are answers and solutions to that, but somehow I decided not to try so hard, especially that we decided that it would be ok to have a backup once a day. YMMV if you need to do it more often. When that was out of the way, it was clear I should go with rsync.
