Antigravitas posted:I doubt they'll fix btrfs' myriad deficiencies. I'd assume they use it as a single disk fs with transparent compression and snapshots, and in that use case btrfs is fine. pretty weird to conflate "anything" with "raid56" (and you can use raid56 too, just research it and know about the caveats)

Tankakern posted:(and you can use raid56 too, just research it and know about the caveats) This. I have an array of 8x8tb spindles in a btrfs raid6, it's my primary media store, but honestly I just consider it a cache between usenet and kodi -- anything rare gets backed up elsewhere, but most of it can be obtained from usenet again in minutes. (really this makes me think I should drop it to raid5 now). Over the course of two years, I've had to rebuild the filesystem once, because I was rebalancing from 6 disks to 8, and a curious cat disconnected the array's usb-c cable from the host, leaving the fs in a bad state. Otherwise it's been just peachy.

Tankakern posted:pretty weird to conflate "anything" with "raid56" I am not. Literally every facet of btrfs is broken by design, from admin tools to behaviour in degraded mode to data loss issues trying to recover from them. Single disk use is the only use case for btrfs. If I needed redundancy with btrfs, I'd use mdraid with btrfs on top. (I don't, because I'm responsible for hundreds of TB of research data, and I'm not going to entrust that to btrfs)

Farmer Crack-rear end posted:assuming btrfs wasn't buggy, would there be particular benefits to using btrfs raid instead of mdraid? in theory, btrfs can be smarter about writes by knowing the underlying array layout in reality, you do it because you're bored, your data doesn't matter, and you hope to be able to catch a bug or two that might help it become production-worthy in the future.

Farmer Crack-rear end posted:assuming btrfs wasn't buggy, would there be particular benefits to using btrfs raid instead of mdraid? Yes, several reasons in fact. As the fs knows exactly which blocks are used and which aren't, it can reduce the amount of data it has to transfer to a new disk when a drive fails. That's important since you want to return to normal service asap when a drive fails. Since the fs checksums every block it can detect when the platter gives it bad data and instead read from redundancy. That's something mdraid can't do. There are also issues where a drive loses connection to the array for a bit and is out of sync. If the fs directly controls the array, and if the fs is properly designed, it can catch up the disk very quickly. All of these things have massive asterisks and foot guns with btrfs, but they work exceptionally well in zfs.

The_Franz posted:it's fine as long as you aren't using raid 5 or 6 this has been an issue since 2014 and is apparently by design since it's mentioned on the wiki but not in the manual pages. meanwhile, the only company who uses btrfs at scale, where data fault tolerance might be tested in the real world, only uses it for scale-out load-balancing orchestration where, if anything fails, they simply shut down an instance and reinitialize the instance from their proprietary filesystem. edit: there's also a fun little caveat that if you try to verify that all the data matches the checksums stored on the disks it isn't self-healing because you may have to balance the array, nor are there things like persistent read or write caches, in-line encryption, in-line data-deduplication and the big plans to have up to 6 disks worth of distributed parity are nowhere to be seen.

speaking of wayland i figured out that i apparently cargo-culted all of the xorg meta-port on freebsd for nothing, none of it is needed if you're running wayland - all that's required is pulled in as a runtime dependency either via Xwayland or things like pango or gtk so i ended up snipping almost 100 ports from my build Progressive JPEG posted:ooh i found this synergy client for wlroots/kde-wayland/raw uinput so thats looking promising

my homie dhall posted:zfs on Linux is embarrassingly slow and bad, don’t use it I love how every post or high level "how-to" about zfs on linux (or any os, really) related completely ignores how unsuitable a default config zfs is anywhere but on a file server. The typical new zfs user spends about 6 months before they go "where the gently caress did my ram go?" and learn about configuring arc.

nudgenudgetilt posted:is it safe to use xfs on a machine without a battery yet? the answer is sort of. xfs does now order data writes with respect to metadata writes so files full of nulls should generally not happen aiui. however it does still take full advantage of the fact that posix does not guarantee anything will hit disk until you call fsync. xfs is great for workloads that call fsync appropriately, which basically means databases
