I have just upgraded from FreeNAS 8.0.2 to 8.3.0 Release-p1.
After the update reportedly succeeded I was going to upgrade the ZFS pool from ZFSv15 to ZFSv28. First, I checked the status of zpool. At that time I discovered that the pool has errors. Here is the output of the
zpool status -v command:
[root@freenas] ~# zpool status -v pool: first 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. see: http://www.sun.com/msg/ZFS-8000-8A scan: scrub in progress since Sat Feb 2 17:15:20 2013 496G scanned out of 886G at 74.9M/s, 1h28m to go 0 repaired, 55.95% done config: NAME STATE READ WRITE CKSUM first ONLINE 0 0 2 mirror-0 ONLINE 0 0 4 gptid/5f279dd0-0ce9-11e1-919a-001871691677 ONLINE 0 0 4 gptid/5f76d1d1-0ce9-11e1-919a-001871691677 ONLINE 0 0 4 errors: Permanent errors have been detected in the following files: firstname.lastname@example.org:<0x198b> email@example.com:<0x4b3> firstname.lastname@example.org:<0x18ec> email@example.com:<0x9fd> <0x1eed>:<0x4b3> <0x1efd>:<0x9fd>
As you can see from the output I have already started the scrub. So far it did not fix any errors but only found 2 extra checksum errors.
I read the recommendation in other forums to first delete the files with errors and then do the scrub. Question is: where to find and how to delete the files like
