Repairing Transactional Volumes

Because a transactional volume is a “layered” volume, consisting of a master device and logging device, and because the logging device can be shared among file systems, repairing a failed transactional volume requires special recovery tasks.

Any device errors or panics must be managed by using the command line utilities.


If a file system detects any internal inconsistencies while it is in use, it will panic the system. If the file system is configured for logging, it notifies the transactional volume that it needs to be checked at reboot. The transactional volume transitions itself to the “Hard Error” state. All other transactional volumes that share the same log device also go into the “Hard Error” state.

At reboot, fsck checks and repairs the file system and transitions the file system back to the “Okay” state. fsck completes this process for all transactional volumes listed in the /etc/vfstab file for the affected log device.

Transactional Volume Errors

If a device error occurs on either the master device or the log device while the transactional volume is processing logged data, the device transitions from the “Okay” state to the “Hard Error” state. If the device is either in the “Hard Error” or “Error” state, either a device error has occurred, or a panic has occurred.

Any devices sharing the failed log device also go the “Error” state.
