[gpfsug-discuss] Trapped Inodes

[Luke Raimbach]

Hi All,

I've run out of inodes on a relatively small filesystem. The total metadata capacity allows for a maximum of 188,743,680 inodes.

A fileset containing 158,000,000 inodes was force deleted and has gone into a bad state, where it is reported as (NULL) and has state "deleted":

Attributes for fileset (NULL):
===============================
Status                                  Deleted
Path                                    --
Id                                      15
Root inode                              latest:

Offline mmfsck fixed a few problems, but didn't free these poor, trapped inodes. Now I've run out and mmdf is telling me crazy things like this:

Inode Information

Current GPFS build: "4.2.0.3".

Who will help me rescue these inodes?

Cheers,
Luke.
