- sippingabonedry 7d agoIf I'm forced to use Linux, sure. I could drop bricks on and cord pull those all day and they would not lose data. Which is a small ask for a filesystem IMO.
- andriy_koval 6d agowould want to have compression..
- simoncion 6d ago> would want to have compression.. I learned about VDO today. [0][1] I'd never heard of it before, but I'm using Gentoo Linux and both the dm-vdo kernel module and the 'vdo' software provided by [1] are distributed by Gentoo... so this isn't some weirdo Red Hat thing. It looks like you manage and used these just like any other thin-provisioned LVM volume [2], but -like I said- I've not used this before, and have only just skimmed the docs, so it's possible that I'm missing something important.

- andriy_koval 6d agoYeah, I know that thing, but oddly they support only lz4 compression which is much weaker to zstd used everywhere else.
- simoncion 5d agoI don't see that as odd. It looks like it was released at about the same time that zstd was getting added to filesystems, and a little bit prior to when IBM acquired Red Hat. It's quite possible that IBM decided that "little" things like enhancing LVM aren't worth the money.
- andriy_koval 5d agoIts odd to me because it looks trivial to add another compression algorithm implementation
