Devices has experienced an error resulting in data corruption...Help!

[LeftyMcToast]

Hi everyone,

New to freenas and did something really stupid. My data is on one drive and the only off device backup is a little antiquated.

I got this error: "CRITICAL: March 28, 2018, 12:02 p.m. - The volume CentralNas state is ONLINE: One or more devices has experienced an error resulting in data corruption. Applications may be affected."

zpool status -v:
pool: CentralNas
state: ONLINE
status: One or more devices has experienced an error resulting in data
corruption. Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
entire pool from backup.

What should I do to salvage my data? I can't access the hd over the network anymore...

You say you can't access the HD over the network, however, can you ssh to the server and list files on the HD ? If so, copy them off somewhere (rsync perhaps?) to another system or maybe connect a USB drive, configure it as a standard disk and copy there ?
