| Environment: |
CentOS5.5 with lustre version 2.X checked out on April 7th 2011. Issue is present on the MDS only |

| Severity: | 3 |
| Rank (Obsolete): | 10089 |
| Description |
|
On the MDS you can easily gather mdt journal stats by a read to /proc/fs/jb2/<mtd dev id>/info. This file is read only so it is impossible to clear the values to make data analysis easier. |

James This is a change that we might consider for a future 2.x release but would not include for 2.1 Peter |
