First, I’m sorry I have been so quiet on the web, bu I’ve just come back from 15 days of medical leave due to a Bursitus in my elbow, which made it extremely hard to write anything with a cast. But that did not stop me from swapping disks in Nexenta Storage server.

I’ve been running a ZFS Pool with 8x Hitachi Deskstar SATA 1TB HDS7210KLA330 for over 1200 days, and out of the 8 disk, not one has failed me. With 8x 1TB SATA Disk in mirror as seen in my previous Nexenta storage for the vLab article, I used to have 3.14TB Usable space. But I needed more, and I wanted to replace these 3 years old disk. I slowly swapped one disk per mirror at a time. Each disk resilver took just more than 8 hours.

I have now finished the complete replacement with 8x Seagate Barracuda ST3000DM001-9YN166 (3TB) disk. My current ZFS Pool is now as follows

After the migration, the ZFS Pool is now of 10.9TB of Usable space.

This should give me quite a lot of space for new virtual machines. I will run some more performance test in a few days add them to this article.
