    Phoronix: Linux 5.1.5 Kernel Fixes The Latest Data Corruption Bug

    For those concerned by the kernel's most recent data corruption bug involving LVM, dm-crypt, and Samsung SSD drive combinations leading to FSTRIM/Discard wiping too much data, the issue should be resolved in the newly-minted Linux 5.1.5 kernel...

    been having screen lockup problems too with 5.1 though i can still ssh into it.
    have a vega 64.
    A bit OT for this thread, but...

    Possibly not directly related, but when I moved to kernel 5.0.0, I would get the GPU attached to output dropping off the PCI-E bus at fairly regular intervals - between 5 and 20 minutes after graphical login - reverting to an older kernel stopped it. As I am dependent on CUDA, I only use nVidia cards in Linux. It happened repeatedly on two different systems, a 2990WX/X399 box with RTX 2080Ti's and a Ryzen 2700X/X470 with GTX 1080Ti's. In both cases, returning to an older kernel stopped it from happening.

    No issues with 5.1.5 though. Vega 56.
    Seems good on 5.1.5, been running all day with no hang.

    I don't think you need LVM to use LUKS.

    If I used RAID, I'd do it in my storage server.

    a very big that.

    LVM is bloat, and only makes sense in server setups.

    These articles have made me glad I'm a ZoL & BTRFS user (with an eye on bcachefs). I just prefer my tools to be more integrated and ZFS is the best in that regard; with BTRFS and bcachefs showing promise. At the end of the day I trust ZFS more than BTRFS and I trust either of those over volume layer + encryption layer + file system layer in whatever order a setup might require.

    I've had all my Steam games and multimedia on a ZFS drive for three years now. Started as .6.x and is now .8.0 and I haven't had a single problem sticking with their point releases and rc's. Outside of the lackluster bootloader support that plagues all advanced setups from LVM2 to BTRFS to ZFS, it's a great file system and it has always kept my data safe through power outages, crashes, etc.

    LVM has nothing to do with RAID. You'll probably want btrfs, zfs, or mdraid instead. mdraid != dm.
