Chapter 2 NAS Head 2-83
Once a StorEdge volume reaches 90% disk space utilization, StorEdge will cease to
create scheduled checkpoints. Once the volume reaches 95% disk space utilization,
StorEdge will delete checkpoints, beginning with the oldest.
Another possible reason for checkpoint creation failure is that the checkpoint limit
for a particular volume has been reached. A log message similar to the following
will be recorded when StorEdge cannot create a checkpoint:
7/30 22:00 I ndmpd[327]: ENOSPC No space left on device
chkpbkup prepare vol1 (create)
This message can indicate that the disk space threshold (90%) has been exceeded, or
that the limit of 16 checkpoints for a volume has been reached.
To check disk space utilization on the StorEdge, proceed as follows:
1. Connect to the StorEdge via Telnet, and type “admin” at the [menu] prompt and
enter the administrator password.
2. At the CLI, enter “df”.
StorEdge fails to send diagnostic email
SMTP (email) configuration allows StorEdge to send diagnostics and urgent
notifications directly to your mail server.
First, check the system log. Most SMTP problems can be identified precisely by
checking the system log.
1. To do so, access the StorEdge via Telnet.
2. Type “admin” at the [menu] prompt and enter the administrator password.
3. At the CLI, enter “menu”.
4. Select option “2”, “Show Log”.
The fourteen most recent syslog messages are displayed.
5. If email related messages are not found, select option “1”, “Show Entire Log”.
6. Browse through the log one screen at a time, looking for any messages relating to
email issues.
7. If no messages are found, attempt to send a diagnostic again.
All attempts to send email, successful or not, generate a log message.
The following are some of the most common email related messages and their
causes. Note that the messages may vary slightly, depending on the mail server.
smtp: Could not send mail, err=-1
