I use btrfs for several years now — not with Guix System, though I do have Guix installed on top of Ubuntu on btrfs so I do have /gnu/store on btrfs. My experience is that it is zero-maintenance, at least on a personal laptop workload. Btrfs has matured a lot over the years, so there’s a fair amount of outdated advice still floating around on the Internet. You’re probably thinking of the ‘btrfs balance’ command. In the past, it was useful to run it every once in a while to avoid spurious ENOSPC errors. This problem has since been fixed, and current advice is that regular use of “btrfs balance” is now considered detrimental rather than beneficial since it puts more load/stress on the disk without any practical benefit. -- Thanks, Thiago

If your problem is really being out of free inodes, I don't think the "large_dir" option is your solution, because it only increase the number of files per directory limit, it does not increase the available number of inodes. Maybe you should manually create the filesystem with mke2fs and specify a bigger number of inodes with its "-N" parameter. Tell us if you find a way around the problem. -- Vincent Legoll
Re: Running Out of Inodes
Heh, – well – I tried the large_dir suggestion in that thread and GRUB had the same freak-out (in retrospect, not surprising as the E-mails are only from 2020; dunno why I thought I'd seen 2017, on first read…). I remember, when first trying to look into this, seeing someone say, "This is why I always use Btrfs for my /gnu/store partition," so maybe that's my best bet. Out of curiosity, I read that Btrfs requires periodic fragmentation; how often do you find yourself doing it and do you use any particular program for it (if you don't mind sharing, of course; I know it's not directly Guix related)?
