As for BTRFS I think its also pretty good. Its just that I have the impression its development is guided by the needs of its sponsors and sadly for us META doesn't need RAID5.
You can mix devices of different sizes and types on bcachefs. You can have foreground and background devices to balance performance and also different compression settings for foreground and background transactions.
You can set replicas=N to the individual file or directory on bcachefs. For example files you can just re-download or re-build. Likewise you can set a higher number of copies to important files.
In fact they delivered the erasure coding for parity raid back in march this year.
The thing is that as soon as you seriously give a chance to Bcachefs you see how good it is. I can only tell you that mixing different device tiers and having a per-file/directory replication setting is a god send specially in these times where storage costs more than gold.
>Combined with SVE2 vector operations and software optimization,
It’s ARMv9.
Garage is good but has weird tooling and a terrible searchable term. You'll receive lots of garage doors and electrical gate results when searching for issues with it.
The biggest problem with Garage is the metadata on an sqlite. If you have a single file and that sqlite corrupts then all your data is unaddressable and treated as pile of anonymous blocks. If you have multiple servers you can rebuild the metadata but if you have only one server you REALLY need to make sure that file is backed up.
So if you use S3 as a backup you have to keep a backup of your backup.
RustFS is closer to Minio, but I hate the way they log stuff. They basically use journald as a metric database dumping json formatted lines about library calls and how long they took. Its hard to make sense of those logs. Its the kind of log not meant to be human readable but to render on a dashboard.
Why not just publish these as a prometheus endpoint?
Also high CPU usage for no reason. I also noticed RustFS constantly trashing disk and keeping 10% CPU usage while looping some health check I have no idea how to disable (I've tried RUSTFS_SCANNER_ENABLED=false and others with no results). And of course lots of json metrics on journald.
I personally prefer garage because my backup box sit at my office and I like not needing to listen to HDD sounds all day every day while Rustfs loops its health check.
I've fixed that with secure boot (my own keys, not Microsoft's) and TPM2. From that host I can run a program named Tang, which operates in conjunction with another program named Clevis.
On hosts without secure boot such as RPis and other ARM SBCs, Clevis will contact Tang at boot time and decrypt the disk.
Incidentally my x86 with secure boot has intel vPro so the KVM is not needed. The remaining sisters have a piece of lost technology used for decades to solve the KVM problem: serial (UART specifically) connections.
Some seasoned sysadmins might have memories of dialing their Sun servers serial ports for remote administration.
Maybe just get these on an open telemetry endpoint instead? I also don't get why people send by default json logs to journald as it's clearly meant to be a replacement to syslog which is already a good standard.
It also seems faith in IA64 was the meteor that killed most of these self developed RISC architectures.
It is interesting to see that as Linux drops support for legacy computers NetBSD still welcomes them. This is a NetBSD thing as it's not so much for FreeBSD.
As of now NetBSD is probably the go-to operating system for vintage hardware.
Jump today most countries stable enough to build infrastructure are democracies and the white collar people you are demonizing do vote and that immense investment in infrastructure is not really easy to relocate.
So people in dubious legal circumstances are locked out the internet?
And lately the interface has been so convoluted and nonsensical. DNS records sure now “policies”, you can only assign very essential rules like setting routing rules to known objects based on MAC address - the ui doesn’t allow you to pick an IP address.
I wanted to create a special routing rules to allow a container using macvlans to always leave through ISP2. Since this is a macvlan the interface MAC address was different every time the system started. Mind you “ip x.x.x.x goes through link 2” is one of those basic things firewalls and routers do since forever but if the object doesn’t exist on their automated inventory then forget it.
I am nothing but grateful for Samba and Rsync.
Then it's not unencrypted anymore because sec=krb5p handles signing and encryption. I have better throughput using sec=krb5p than with samba signing and encryption. I don't know if it's because Samba uses GNUTLS but the transfer speeds are always awful.
My beefs with NFS is MacOS being extremely quirk with settings. That and the extremely misleading error messages.
>Dev1: Here's a great idea! Let's run an insecure network server in Kernel space!
>Dev2: OMG! You're so smart! Let's also exclude any encryption!!!
If it wasn't such a cool idea they wouldn't be doing it again, this time with direct access to memory: https://docs.kernel.org/filesystems/smb/ksmbd.html
