2048 bytes inode, I'd bet your filesystem is fragmented enough to not have any
more room to create inodes into it.

for creating new inodes you will need a contiguous space of 131072 bytes, which
you don't have anymore, so you won't be able to create any more files into this
filesystem, unless you free up some space to allow room for the creation of new
inodes.
XFS create inodes in chunks of 64 inodes, if you don't have enough space for
that, then you get a -ENOSPC as you are getting.
Cheers.
