I am a big fan of Solaris Volume Manager largely due to it’s simplicity and stability, and being easy to recover when something happens. Most of the places I have worked at SVM is mainly used for root mirroring (and Veritas VxVM is used for everything else). Sanjay Nadkarni from the Sun SVM team posted a message to lvm-discuss with an announcement of the availability of SVM internals. For those of you out there who wants to learn about the SVM history and how it works, it’s time to dive in.
