Hi,

I got email notifications about this on 2 days before, I received another email today with the same.


SMART error (OfflineUncorrectableSector) detected on host: *******.com

This email was generated by the smartd daemon running on:

host name: *******.com
DNS domain: *******.com
NIS domain: (none)

The following warning/error was logged by the smartd daemon:

Device: /dev/sdb, 1 Offline uncorrectable sectors

For details see host's SYSLOG (default: /var/log/messages).

You can also use the smartctl utility for further investigation.
No additional email messages about this problem will be sent.

I'll leave a more proper answer to someone smarter than I, but just add that you might want to be sure you've got everything backed up properly, right away. But not to that drive, that one looks like it may be in trouble.

You may also want to contact your DC ASAP and let them take a closer look for you.


GL!

First of all, have you reviewed /var/log/messages as it notes to do?

Next, what I've read about the issue, it sounds like you definitely need to get the drive backed up to a location off the drive and move things. Basically, there are either bad sectors on the drive or it isn't spinning fast enough when the system starts up, more likely the bad sectors.

Here's a discussion on dealing with bad sectors:

Bad block HOWTO for smartmontools

You can start losing random data on the drive at this point. You might also lose the drive during a reboot. I would take the message very seriously.

You need to get the machine migrated in all likelihood. Talking to your datacenter or NOC is the best course of action right now along with ensuring to have full backups off the machine.
