That, and if not possible one can try to get the used kABI symbols graylisted at Red Hat, to get informed when they change.

Let's take a task like "uncompressing a file". It's clear that a Raspi is uncompressing slower than a new and shiny Thinkpad.. but the Thinkpad also uses much more power. Who is mo…

I played through more scenarios with the "I have a laptop, and want seamless switching between ethernet and wireless". shadowsocks proxy seems like the best choice, allowing transp…

You should pay attention to make the ethernet the preferred interface. If aggregation of bandwidth over the various underlying media is important for you: depending on the exact mo…

Nice, was not sure how stable such a setup would be. The applications will not need further modification and just need to be sent over the bond. For MPTCP, as of today the applicat…

Ah, valid point, mea culpa. I have not used nbd, but I'm aware of it. Was very impressed to see even a NetBSD implementation. There is just so much around in that area. In my defen…

+1 I use the older one which uses the kernel from the stock firmware. To my understanding done by the guys who worked also on the original firmware. I have seen just a single issue…

I can recommend the FiiO M3K, especially loaded with https://www.rockbox.org/ . There is now a native Rockbox build (with some caveats), I use the older one from https://forums.roc…

Of course, besides simply supporting recovery from bit rot, one would also want to have confidence in the implementation. I think the vendors which provide production support for b…

I know someone who did setup ceph just for it's healing capabilities.. but of course one has to familiarize with all of it's administration aspects for that. Setups with RAID1 coul…

- XFS: can use checksummed metadata, changed data (bit rot) will not be noticed, unless extra layers like dm-integrity are used - ext4: same as XFS - btrfs: can with checksums dete…

With the current code, your data becomes unmountable in that case. There is a workaround for getting the data accessable: leave a bit of the underlying blockdevice unused, so when …

The capacity is not changing 'rapidly', instead the whole VDO device is thin provisioned. Let's assume a 1TB harddisk, then when creating a VDO device ontop, you can have that dire…

Yes, VDO is transparent for the layers above, like filesystems. XFS+VDO might be preferable to BTRFS, if it has the features you need. - LVM could be used for snapshots, but the sn…

Nothing prevents you from running VDO ontop of ZFS, apart of that not being in focus/tested at Red Hat. I do not expect issues from purely running both layers, but maybe things lik…

If your data directories have much redundancy (so deduplication can help), or are nicely compressable, then VDO can also make sense for home setups. Like companies, you would consi…
