Stale File Handle SSH Error
| Item | Description |
|---|---|
| Command | df -P |
| Error | df: /some/mount/point: Stale file handle |
| Result | FAIL |
| Description | The df utility is used to collect the filesystems present on a Linux/UNIX device. In some cases, particularly related to NFS, the kernel thinks that a filesystem is mounted when it is not, or an NFS filesystem has been detached. According to the POSIX standards, the df utility will return a non-zero exit status on an error, which it does in this case. In order to ensure that all filesystems mounted on the system are properly accounted for, in the case that df returns an error it is considered a critical command failure. |
| Recommendation | Investigate the system in question to determine why df is unable to report on certain filesystems, and fully mount or unmount the problematic filesystem. It may also be possible to cause the system's cache of mounted filesystems to resync. |
