Where is the redhat ecosystem trending with regard to CoW filesystems ?
Are people regularly using ZFS-on-linux with redhat ? Or is there an officially sanctioned CoW choice from redhat ?
Or is that not on the radar at all right now ?
- merb 10y agoWell RedHat defaults to XFS which has experimental support for CoW. https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0cbbc422d56668528f6efd1234fe908010284082 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/lin... Came in 4.9 and 4.8 (the commit provides the building block). And I also think Dave Chinner (works at RH) put a lot of effort into it? (but I'm not 100% sure)
- lima 10y agoXFS is one of the most robust filesystems, too. The xfstests testing suite is basically the standard for filesystem testing, even for non-XFS filesystems.
- bonzini 10y agoFor RHEL7, XFS is the recommended filesystem. It has a lot of backports so don't be fooled by the 3.10 kernel version---but not CoW. Btrfs is not mature enough. ZFS-on-linux is not supported and I've never seen a customer using it.
