Crazy SCOM Alert: Disk Corruption

Friday, August 8, 2014 in Technical Articles (Views: 1973)
Flashback: 1991. A program was giving you a problem. Generally, not far behind would be the dreaded "Out of memory" error.

Now, we've changed messages, but can't always get an accurate error description. Someday.

Enter the issue I ran into when I saw that a server data volume was corrupted in SCOM - seems like a reason for panic. I get to the server, everything is fine - chkdsk is clean. I close the alert, it comes back, everything is fine - chkdsk is clean. Is this a stupid test?

So, I took things a step further, running fsutil, my output..

fsutil repair state

Global Corruption State: 0x14 - Online Scan Needed

Volume Name: C: (\Device\HarddiskVolume4)
Corruption State: 0x00 - Clean

Volume Name: E: (\Device\HarddiskVolume2)
Corruption State: 0x00 - Clean

Volume Name: ?? (\Device\HarddiskVolume3)
Corruption State: 0x00 - Clean

Volume Name: G: (\Device\HarddiskVolume1)
Corruption State: 0x14 - Online Scan Needed

Needless to say, G: was my issue, so I simply ran:
chkdsk g: /scan

After that, G: came up clean like the others. Amazing how chkdsk and chkdsk /f saw nothing, and /scan repaired it. It didn't provide any additional output between chkdsk and chkdsk /scan. But, it's fixed now - if you run into this issue.
