Archive for the ‘RAID’ tag
I spent a little time yesterday doing some things with the “summary” tool from Aspersa. I added support for summarizing status and configuration of Adaptec and LSI MegaRAID controllers. I also figured out how to write a test suite for Bash scripts, so most major parts of the tool are fully tested now. I learned a lot more sed and awk this weekend.
There is really only one way to get status of Adaptec controllers (/usr/StorMan/arcconf), but the LSI controllers can be queried through multiple tools. I added support for MegaCli64, as long as it’s located in the usual place at /opt/MegaRAID/MegaCli/MegaCli64. I am looking for feedback and/or help on supporting other methods of getting status from the LSI controllers, such as megarc and omreport. If you can contribute sample output from these tools, please attach them as a file to a new issue report on the project’s issue tracker. (Don’t paste them as text, please — formatting and whitespace will get mangled. Tabs and spaces need to be preserved.)
I am slowly gaining insight into how best to write a similar summary tool for MySQL servers. The goals of this tool are very specific — including things like diff’able output. I’m figuring out what went wrong with Maatkit’s mk-audit tool and how to go about it differently.
