This entry was posted in Software development, Storage, Travel and countries and tagged DRAID, OpenZFS, ZFS on by Carles Mateo. Use the zpool replace command to add the new drive into the pool. The initial design only supported configurations where the group size divided evenly into the number of data drives in the config. It breaks the number of drives in the configuration into raidz groups and randomly distributes the data blocks across all available drives. Special greetings to my Amazing Team in Cork, Ireland. The dRAID data layout is layered on top of the raidz infrastructure in ZFS. We benchmarked Rebuilding times for different drives size, i.e. You can download the video of the sample Rebuild with DRAID in here:ĭraid-rebuild-read-write-1sec-vokoscreen-_11-37-48Īlso in the Hackaton I presented my mini utility run_with_timeout.sh to execute a command (zdb, zpool, zfs, or any shell command like ls, “sleep 5 ping ”…) with a timeout, and returning a Header with the Error Level and the Error Level itself. DRAID Rebuild Performance The Declustered RAID implementation, is a Work in Progress in ZoL, however in my Department I wanted to see how far can this technology can go. Here you can watch mine and all the presentations. If you would like to contribute to this document, please email or for access. This September I was invited to talk in OpenZFS 2018 about DRAID and Cold Storage (Spinning drives) in San Francisco, US. This is a rolling agenda for the monthly OpenZFS Leadership Team Meetings.
