Hello to all,
I write here because the Italian forum is poorly attended.
Saturday I received an email from freenas telling me: "critical errors."
the alert message in the web interface was: Device: / dev / ADA3, 2 Currently unreadable (pending) sectors (changed +1).
I tried to give a restart, it got worse until the status of the raid became: DEGRADED.
I connected the monitor to the server, and I saw it was started some process, after which the raid was returned: HEALTY, but the number of unreadable sectors ADA3 unit has grown to about 70.
I have not yet launched any of the smart status check, no nothing. After the long process I managed to make a back up from scratch of sensitive files. Remain about 15 TB of movies that I can not save elsewhere.
I looked at some official guides and video about replacing a failed disk, and they show the procedure, where the disc (in the resulting list ONLINE - while all my records are ONLINE), clicking on "replace" and select the parity disk it is not in the list.
Also I have a raidz1 but in the list of disks that make up the volume appear to me all 6 discs which then make up the replace I can not do.
I had thought to extract the ADA3 disc, initialize it to another computer and put it back like new, then in theory the system should rebuild the new drive without unreadable sectors, but I'm afraid it is a bullshit.
I await your advice because I'm a bit anxious about how to move to avoid worsening the situation.
Thanks for your help and sorry for google translate.
