Cisco CUCM: "EXT3-fs error (device sd(8,6)) in start_transaction: Journal has aborted"

This has bit me a few times with this one phone system here in the last couple of days.  I get this:

I couldnt figure out what was going on with this, so I called TAC, who referenced me to the following bug:

7828-H3 server goes down with Journal Aborted error
Phone services will go down, and server will only be semi-responsive. Local console access will show the following error constantly scrolling across the screen.
EXT3-fs error (device sd(8,6)) in start_transaction: Journal has aborted

During normal operation services will go down. Reboot will bring services back up for a while, anywhere between a couple hours and a couple days. Seen most frequently on
MCS7828-H3-K9/BE but has been reported on MCS7825-H2-IPC1 and MCS7825-H3. This defect is for the MCS7828-H3 servers only.

Shut down the server, and remove the first hard drive until a final fix is available.
If server still fails, try switching to the other drive. Watch during boot up for any errors which might indicate hardware failure (SMART errors in particular).
If server stills fails on 2nd drive, leave one drive in, and reinstall CUCM.

Further Information
This issue was tracked to a firmware problem on the hard drives. A firmware update is available on Please download the readme and iso for 7828h3-hddfwupdate-v11 under the MCS 7828-H3 Unified Communications Manager Appliance. 
Direct link:

Alternatively you can find the download under the MCS 7828-H3 section, "7828h3-hddfwupdate-v11.iso" is the correct file name.

So, at the moment, I have one drive out until I can get the download.
