ZFS HDD & Corrupted Data

January 7th, 2014, 10:22

I have a client who is using ZFS to store their data. They are not using the ZFS Snapshots either. There seems to be an issue that when data is written to the drive, some of it is becoming corrupted - specifically, the file signatures are being stripped from the files.

This is happening to all different file types - PDFs, DOCx, XSLX, etc.

Is there a way to restore the data?

einstein9,

The OS is Ubuntu 10.04 - if memory serves me correctly. The device was not in a RAID configuration - it's a single drive.

If you need any other information, please let me know. Thanks.
