zpool status output? have you run zpool scrub [volume]?

 

[marian78]

ok, now is status online - little googling, and fuond this. i use console with:

"zpool replace disk1 da2 /dev/da4" caused the raid to be rebuilt.
"zpool detach disk1 xyz" removed the defunct entry from the array
"zpool scrub data" validated the changes.

it works, in web gui status is online but when i open "view disk" i can still see nonexist disk that i replaced. Now again search with google, and solution is to edit database with sqlite. But i dont know "data/freenas-v1.db" database structure(tables,... - in console sqlite3 i try .tables and .schema, but nothing show)... any help???? thx, marian

edit: i connect to freenas with putty ssh and there is view output sqlite3....strange

SQL database output

Let me guess you are not using 8.0.1beta3 or? All FreeNAS8 pre 8.0.1beta3 have a known problem with replacing drives, if you do it through the shell it will become de-synced with the DB.

 

[marian78]

yes, i use v8.0.1beta3 and before tray v8.0 (same problem). but questions is: v7 have same broblem with replacing disks (or all is automatic like other nassystems)? and how synced shell and db in version 8 (is it possible manualy)? .....
