ext4 on an mdadm raid. It works well enough, and supports growing your array.
Although if I rebuilt this from scratch, I would skip mdadm and just let minio control all the drives. Minio has an S3 compatible API, which I’d then mount into whatever apps need it.
Love mdadm, it’s simple and straightforward.
Love MinIO but it’s not a filesystem and mounting object storage as a filesystem is not a great experience (speaking from commercial experience).
Same experience here. S3 is essentially a key/value store to simply put and retrieve large values/blobs. Everything resembling filesystem features is just convention over how keys are named. Comminication uses HTTP, so there is a lot of overhead when working with it as an FS.
In the web you can use these properties to your advantage: you can talk to S3 with simple HTTP clients, you can use reverse proxies, you can put a CDN in front and have a static file server.
But FS utils are almost always optimized for instant block based access and fast metadata responses. Something simple like a
findwill fuck you over with S3.
ZFS raidz1 or raidz2 on NetBSD for mass storage on rotating disks, journaled FFS on RAID1 on SSD for system disks, as NetBSD cannot really boot from zfs (yet).
ZFS because it has superior safeguards against corruption, and flexible partitioning; FFS because it is what works.
@Hopfgeist @sam I prefer RAID10 on rust.
What are the advantages of raid10 over zfs raidz2? It requires more disk space per usable space as soon as you have more than 4 disks, it doesn’t have zfs’s automatic checksum-based error correction, and is less resilient, in general, against multiple disk failures. In the worst case, two lost disks can mean the loss of the whole pack, whereas raidz2 can tolerate the loss of any 2 disks. Plus, with raid you still need an additional volume manager and filesystem.
@Hopfgeist Speed on large spinning disks. Faster rebuilds. Less chance of complete failure because or URE.
I love em all, especially btrfs. But I have to stay away from xfs. Had so many weird issues with it that made no sense.
Ext4 because it is rock solid and a reasonable foundation for Gluster. Moving off of ZFS to scale beyond what a single server can handle. I would still run ZFS for single-server many-drive situations, though MDADM is actually pretty decent honestly.
Ext4, my needs are simple and in all the years I’ve been using extX, never had a problem
Same. I tried btrfs and ended up with a corrupted drive. I’ve never had ext4 fail on me in a way that wasn’t recoverable. Boring and safe are features I like in my filesystems.
XFS for the moment, but transitioning towards ZFS. I’d never touch btrfs again, it simply is not resilient or as recoverable as a quality file system should be.
Btrfs, because of compression. And I’ve never had any issues with it.
ZFS on file server, fully luks encrypted btrfs on desktop, and probably ext4 or whatever is default on the buntus for laptop and work desktop.
ZFS on freenas/truenas has been rock solid for 10+ year raid. I love working with btrfs snapshots and the ease of adding drives on demand to expand. I don’t think much about ext4 on those systems.
Just ext4 pooled together with mergerfs for my media files. Seems to fit my use perfectly.
Zfs I lost so much data trying to use btrfs. And zvols are neat.
Btrfs. been 7 years no issues. Those with lots of issues may have setup an unsupported Raid configuration.
Ext4 for my root filesystem, although I’ve been eyeing BTRFS for a while now as a replacement.
BTRFS for all my arrays and auxillary drives - aside from one oopsie where some drives had power issues and retained corrupted data (BTRFS managed to recover everything just fine), it’s been a fine experience I guess.
Judging by the amount of responses mentioning being burnt by data loss, I wouldn’t be surprised if most of these were probably caused by running “
btrfs fsck” 😱😅I am also pretty interested in btrfs. I recently redid my laptop and did btrfs for everything there. No btrfs on my server yet though. Ext4 is just really optimal for data recovery. Maybe if I redo my server sometime in the future I’ll start with btrfs.
Zfs for data, vms, lxc, file server.
Ext4 for basically root partitions, maybe ufs on the non-jailed freebsd.
Old policy, separate data and OS so you can switch quickly, had it since dos and never really switched.
Zfs is perfect but heavy, especially the arc so try not to wave it at everything. Ext4 is good enough for anything where I really don’t care about integrity.
Tried btrfs but zfs is awesome because when I’m done I can always send a snapshot from my workers to the main fileserver with zfs-send and keep it around. Zfs-send/receive really change the game, as does zfs’s trusted raid and zlog/l2arc which makes spinning rust fly.
ext4 on boot drives just because it’s so standard and uncomplicated. Data drives either xfs or btrfs, depending on how froggy I’m feeling when I set it up. I don’t use the fancy features of the filesystem. Hell, I barely even use lvm. I find all that stuff just gets in the way. I just want to put files on disk.
I’ve tried zfs, and it seems nice, but when you have a lot of storage, you need to have a lot of RAM to actually make it useful, and I don’t.
