When attempting to mount CentOS 6, my mount fails with
clnt_create: RPC: Unknown host

Many Linux commands accept command-line options and positional parameters. The grep command searches for a pattern in a given file. Its 2 positional parameters are the pattern and the filename. It accepts options such as -i which specifies that the search is case insensitive. An interesting scenario is when a positional parameter has a value starting with a dash ('-'). This makes the parameter indistinguishable from an option. For example, you try to grep the string -tea in a given file.

In my previous post on ZFS I showed how ZFS causes fragmentation for Oracle database files. At the end I promised (sort of) to also come back on topic around how this affects database performance.
