I have a Linux MIPS router with 2.4.17 kernel. Root fs is a tmpfs and /rom is a cramfs. There is 4MB free memory and 3MB free on tmpfs.
I can create a few new empty files, but the next ones fail with "not enough space". However, I can append 1MB of data to an existing file. So my trouble is in inode count.
And my questions:
- Is there any way to dynamically increase inodes?
- If I can't increase it dynamically - Where can I increase it in kernel sources?
