I received an error message on one of our FreeNAS servers. The error says:
CRITICAL: May 30, 2017, 1:36 a.m. - The volume vol_xx (ZFS) state is ONLINE: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected.
The only additional information that I can see is under Volume Status / Scrub. One of the 4 raidz1 drives has a Checksum value of 33. The other 3 drives all show a Checksum value of 0. All 4 of the drives show 0 Read, 0 Write, and show a Status of Online.
How serious is this? Do I need to replace the drive with Chicksum of 33? Is there anything else that I need to do?
Thanks,
