Hi all -
Last month I posted queries to this list (and several other locations, including the forums) asking about people's experiences with btrfs. For the most part it seemed like the experience had improved over time. Most of the concerns were either with interactions with zypper or old perceptions of instability that were based more on old impressions than new testing. With the exception of an ENOSPC issue that had been recently fixed, users actively using the file system seemed pretty satisfied with it.
I posted a followup question a week or two later asking what people thought about limiting the 'supported' feature set in the way we do in SLES so that it's clear to all users which parts of the file system are considered stable.
A quick table of what that looks like:
Supported Unsupported --------- ----------- Snapshots Inode cache Copy-on-Write Auto Defrag Subvolumes RAID Metadata Integrity Compression Data Integrity Send / Receive Online metadata scrubbing Hot add/remove Manual defrag Seeding devices Manual deduplication (soon) Multiple devices "Big" Metadata (supported read-only)
What about quota groups?
Oops, yep. Quota groups are supported too. -Jeff -- Jeff Mahoney SUSE Labs
