Is it depends on > partition size? it does depend on partition size; the inode_ratio = 16384 in mke2fs.conf says 1 inode per 16k of filesystem space. the inode size was also increased a couple years ago, and the default inode count was reduced by half so that the total size remained the same. -Eric > Eric Sandeen wrote: >> cy6erGn0m wrote: >> >>> I have found issue with ext4 partition. >>> I created many many empty files with the following way: >>> [cy6ergn0m@cgmachine heap]$ seq 1 10000000 | xargs touch >>> >>> But this command crashes asfter a while with a error 'no space left on >>> device'.
