With the release of kernel 5.12, btrfs gained basic native support for host managed Shingled Magnetic Recording (SMR) HDDs. This initial support allows formatting and mounting an SMR HDD using btrfs (simple profile), therefore enabling high capacity storage at a lower cost while hiding the sequential write constraint of these devices. Work is also on-going to add support for high performance NVMe Zoned Namespace (ZNS) SSDs.
This talk will summarize btrfs zoned storage support status and discuss future improvement plans. In particular, we will present ideas for a de-clustered erasure coded volumes which will allow resolving the long standing btrfs RAID5/6 problems while enabling RAID (and erasure coded) volumes using zoned storage devices.
Who in addition to the speaker needs to be in the virtual room for this to succeed? Neal Gompa (ngompa) Josef Bacik (joseph) Davide Cavalca (dcavalca)
This is a: 25 minute Talk
Anything else we need to know? The speaker will be Johannes.Thumshirn@wdc.com Johannes.Thumshirn@wdc.com.

Any open spot in Track 2 works. Johannes and I can accommodate any time on Thursday and Friday (preferably). But Saturday is OK too.
Thursday August 5th at 18:00-18:30 (UTC), Friday August 6th at 14:30-15:00 (UTC) or later would all work well.
Hi @damien-lemoal I added this session in on Friday, please review. Thanks! https://fedoraproject.org/wiki/Nest_with_Fedora_2021_Schedule#
