A general Linux question: why does Linux report 'out of space' error
when it runs out of inodes? Can't it distinguish between the 2
conditions to give the correct message or is there some other issue?
Just curious as I just go this after making 1,000,000 small test files
and got this (du -m -i).
Check out /usr/include/asm-generic/errno-base.h and see that the error
you are mostly likely getting is ENOSPC which gets translated to the
libc sys_errlist as "No space left on device". There is just the one
error code there, no space, and I believe is simply used generically
for both errors. There is no E-out-of-inodes error code. Therefore
no way for userland programs to report anything different.
thanks for the pointer. So it seems like something that goes back aways
in Unix land, at least if it is in a 'generic' code. So I'd expect to
have the same thing in bsd, linux (and maybe win32?). Hmm. I cant think
of why a full inode table would be treated the same as a full partition.
Will have to look in some unix lore maybe...
cheers,
Kev
