Hi List,

I've ran into a strange (possibly) inode problem within
one vserver. Althought df -i on the host shows that the
filesystem on which the vserser lives has IUse of only 1%,
we get "cannot create" errors on new files.

Having seen that there is a configuration option
for the maximum number of inodes dedicated to a vserver,
I have the following questions:

- What is the default limit when this option is not set?
- What mechanism is used when checking and enforcing vserver
   inode limits?
- The total number of inodes on the filesystem on which the
   vserver lives is 324350 at the moment.
   Could someone comment if is so high that special actions
   need to be taken?
- Could any other limit be causing the error? E.g. number of
   files limit or whatever?

Here are some server facts:
* Gentoo vserver kernel, 2.6.32-vs2.3.0.36.28
* util-vserver 0.30.216_pre2883
* Filesystem ext3, default settings when formatting

Best regards,
Tor Rune Skoglund
