Devices under GFS2 filesystems cause all processes accessing them to hang on Red Hat Enterprise Linux
Issue
- Somehow a gfs2 file system got corrupt.
- Running blkid <dev> -c /dev/null on the device with the corrupted file system hangs indefinitely. The process is shown in defunct (D) state.
- blkid /dev/mapper/VolStorage01-cluster_data -c /dev/null
Environment
- Red Hat Enterprise Linux (RHEL), including:
- Red Hat Enterprise Linux 5 (RHEL5) Advanced Platform
- Red Hat Enterprise Linux 6 with Resilient Storage Add-on
- Red Hat Cluster Suite cluster with at least 2 nodes
- GFS2 filesystem mounted on at least one node
- Mount options for errors are default, or errors=withdraw. Problem will not occur if errors=panic is configured.
- Filesystem corruption was detected and the filesystem was withdrawn.
