    XFS Code For Linux 6.14 Improves Realtime Device Support

    Phoronix: XFS Code For Linux 6.14 Improves Realtime Device Support

    In addition to the Bcachefs features and new Btrfs code for Linux 6.14, the XFS file-system changes were merged on Thursday for this next version of the Linux kernel...

    Good Realtime performance is desirable, a good goal.

    Another good goal I wish they'd prioritize is data checksumming.

      Having the realtime device feature ready for use by fileserver without an app with special code to access the rt device is nice :-)
      I don't think data checksumming is on the roadmap to be able to priorize because that's still available on the block level of an external hw-raid under xfs ... but maybe who knows ...

        In case anyone else had never heard of this, and that the Phoronix Forums shall properly be superior to r*ddit...

        Apparently XFS has a feature where you can add a "realtime" block device to the FS, and mark particular files or directories as realtime (rtinherit attribute seems like the best way, IMO). Such files are then allocated on the realtime device, with data structures chosen more toward the latency end of the latency vs. space-efficiency tradeoff. For the realtime device, it is presumably prudent to choose an optane drive, or at least a good enterprise SSD with power-loss-protection.

          Thanks for sharing the oracle docu link "XFS: Tracking space on a realtime device" for testing but still thinking that mounting eg a ssd (kind of device) on a directory with a separate xfs is a better way instead of the rtdevice way ... or ?! In my opinion the rtdevice would be nice to use for these smr drives if one has bought them accidently and is unhappy and unknown how to use these. Building linear raid out of a ssd raid1 and a hdd raid6 while mounting with inode32 allocator give all inodes on ssd and all data on hdd, maybe give the rt device as third device a test trip how that goes too. Anyway xfs is super cool :-)
