I wasn't aware of all of these "restrictions". If this is true, now I understand why redhat lost interest in BTRFS. 3-4 years more for a "working" RAID56 is absolutely too much, in this case, ZFS support for RAID-Z expansion/reduction (actively being worked on) will be released much earlier (probably, a test working-version later this year and a stable version next year) RAID-Z single disk espansion/removal is probably the real missing feature in ZFS allowing it to be considered a general-purpose FS. Device removal was added some months ago and now is possible (so, if you add a single disk to a mirrored vdev, you don't have to destroy the whole pool to remove the accidentally-added disk) In 3-4 years, maybe oracle release ZFS as GPL-compatible (solaris is dying, latest release is 3 years ago, so there is no need to keep a FS opensource compatible only with a died OS) Keep in mind that i'm not a ZFS-fan (honestly, I don't like it) but with these 2 features added and tons of restriction in BTRFS, there is no other choise. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
