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?

As far as i know you wont be able to restore the data.

Good luck

can i have some details here?
Server OS?
Raid storage or not?

i got some similar case some time ago..

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.

Will you/client accept RAW data?

no names, no folder structure

i spent about 2h in my VM testing something with this damn ZFS
