Today's the first day in my 15 years of using Linux that I've ran out of inodes rather than disk space.
Luckily it's easy enough to fix: create a large empty file with truncate -s 20G filename, format it (e.g. mkfs.ext4 filename), and mount it somewhere you can access.
@minoru xfs ftw
@L29Ah Didn't know XFS lets one change the number of inodes; nice! But I'm not migrating to a new FS just for that :)
@minoru xfs doesn't have a static number of inodes and doesn't allocate them all at once like ext* do

you can migrate to it for its reflinks support: https://bnw.im/u/l29ah/t/xfs
@minoru
@L29Ah Don't really have a use-case for them on this machine, but they're interesting for sure.
