Comment on Solaris 11: User Renames Not Simple Anymore by jmk

One minor point in solaris 11:
If you create the user during installation, the user is added to /etc/user_attr to assume the root role.
You need to change/rename the user in this file, too. I had the luck that I had an root session open after deleting the old user…

Comment on Adventures in ZFS: Storage Sizing by Miro

Pretty nice article. I would only add that you need to also factor % for things that would affect the storage need growth.

One need to keep an eye on what drives the storage usage. Are these tons of PDF/DOC/Excel files from Accounting, images from Marketing or other large data sets from Engineering department, where is that data coming from….

For example: in a company that creates digital radio waves imaging, increasing the number of receiving elements from 1 to 64 could mean 64x increase in storage needed by your Engineering department. This probably doesn’t happen every year so it won’t be on your plan. How do you factor that?

You have to be close to the business to understand its future needs. If there will be some massive marketing campaign that would bring a lot of new customers and knock your calculations off – you need to be aware of it, and factor it to best you can.

Great blog. I just started using solaris 11 in a vm. From the looks of this article it seems that they want you to create a new user and move the data. Strange though. Anyway, I’m a bit surprised that solaris doesn’t want you logging in as root, I assume this is only in multi user mode, but I havn’t tried bringing it down to single and see if root works. I’m very impressed with 11, but they need to port some more software like google’s chrome to it. keep up the great posts!!!

Comment on ZFS: Delegate ZFS Permissions by Jens Henriksen

You might at least on FreeBSD also use the hold permission in order to send and receive snapshots. Otherwise you might get the error cannot hold snapshot permission denied.

Thanks for a great article.
