Description NAC services are down due to hard drive being in read only mode. This this state, files are unable to be written.
Examples of responses in a Read-Only file system:
> touch filename1 touch: cannot touch `filename1': Read-only file system
> service dhcpd restart Shutting down DHCP server rm: cannot remove `/bsc/services/dhcpd/var/state/lib/libnss_dns.so.2': Read-only file system rm: cannot remove `/bsc/services/dhcpd/var/state/lib/libresolv.so.2': Read-only file system done
Possible Causes: Disk full, file system corruption, improperly seated hard drive or hard drive failure. Solution
1. Verify disk space:
df -h 2. Ensure configuration files are copied to a remote server (in case a recovery is necessary). If remote backups are not already scheduled, they can be uploaded using SCP or to a FTP server. 3. Power down the appliance. 4. Re-seat the hard drive. 5. Power up the appliance.
If database is corrupt, restore the last database.
