The flash storage device is not mounted as per Cisco issue "CSCuv67115."

This issue initially occurs only on supervisors in standby state. The issue is not corrected by an ISSU/D, system switchover, or reload, and is observed on a supervisor in an active state.

Logflash is used only to store the output of debug commands. It is not required for stable system operation.

Workaround:
Power cycle the affected supervisor.
In dual-supervisor systems, this is done by powering down the supervisor with the out-of-service module command and powering it back up with the no poweroff module command. Ensure that the supervisor is in standby mode so that the recovery does not affect the stability of the system.

It is not sufficient to reboot the module with the reload or system switchover commands.

Example:
Commands:

1. Confirm that the standby supervisor is in HA Standby:

   show system redundancy status

2. Power down the standby supervisor module:

   out-of-service module <standby sup>

3. Power up the standby supervisor:

   no poweroff <standby sup>

4. Wait for HA Standby:

   show system redundancy status

Monitor the switch show logging output to see if the EXT3-fs error message is still logging on the switch. If the error is still logging, switchover to the standby supervisor and repeat steps 1-4 above.
