Comments for A Technical Architects Diary Thoughts from a Technical Solutions Architect Mon, 12 May 2014 08:07:15 +0000 hourly 1 Comment on Designed to Fail by Chris Kranz Mon, 12 May 2014 08:07:15 +0000 What’s your definition of critical? Syncing or distributing the data to render a device dispensable is a great tactic that I think all enterprises can learn from. Doesn’t need to be low priority or non-critical. Take a look at the database and filesystem world and this is happening with NoSQL systems like Cassandra and MongoDB, and distributed storage like Lustre and Ceph. The problem is removing the dependency on big important IT equipment is not in the best interest of the companies that least the big important IT industry. The horrible cliche of “No one got fired for buying IBM” is so irrelevant now, the reality is that if you don’t stay current with new technologies, you will get left behind!

Regarding off-planet DR, these guys have something although I don’t really know anything about it:

Comment on Designed to Fail by Eric Sat, 10 May 2014 09:20:40 +0000 Hi Chris,
Interested and nice article.For such low availability/reliability designed system like mobile phone and Tablet, we should not put critical information on that and have backup (to cloud) for sure.
I am so agree that even global enterprise has put low priority on the backup/recovery/DR systems, not 100% confirm those system is working and meet the RTO/RPO. It is so risky as most decision maker under estimate the impact of the fail until it happens or as you said, it is too hard to justify…@~@
Could you kindly share more for how to keeping data/DR off-planet, an interesting topic.

Comment on cf by Chris Kranz Thu, 01 May 2014 14:11:01 +0000 You use it in a MetroCluster in order to force the takeover. It’s only used in the MetroCluster and I believe is done only when the cluster is fully broken in the middle, neither node can talk. It forces the takeover ungracefully, not waiting for the partner to confirm anything.

Comment on NetApp Save Config Command by Arek Pater Mon, 14 Apr 2014 11:55:14 +0000 @Chris Kranz
Hi Chris, thanks for feedback. no, I didn´t edit the file. I created the dump, then with the command “rdfile > output” saved on the management system (win server).
Maybe, It would be works with “config clone”, but I don´t understand what this command exactly do?
is it the same like “config dump” except system specific data (serial no. ect?.)

Comment on NetApp Save Config Command by Chris Kranz Fri, 11 Apr 2014 08:01:30 +0000 I think they need to be the same ONTAP version as options change between versions. Its difficult to say what the error might be otherwise. Maybe do a new config dump on the other 270 and then on a Linux machine do a “diff” to see if you can spot any major differences (not in the config, but in the options and format) between the two. You’re not editing either file manually are you?

Comment on NetApp Save Config Command by Arek Pater Tue, 08 Apr 2014 12:25:47 +0000 Hi,
I have a problem with the restoring. I would like to restore the config from old 270 to another 270. what are the important prerequisits to make this possible (same ONTAP version?…what else?) I get in the moment an error message ” restore_config: Didn’t find expected version line in the given config. file, /etc/software/configtest2. Version line fou was: . (/etc/software/configtest2 file initial bytes are 0xfffe2306603d0)”….I didn´t find any text for this error. have you maybe an ideea?
thanks in advance for any help

It explains how to allocate vCPUs in a really nice way, with an example.
