I have a failing 1TB drive next to a 2TB and a 4TB drive in my data pool (Kurgan). I'm not sure what the exact configuration is but the results of are:
It's not reporting errors, but in the FreeNAS GUI I see:
And /dev/ada1 maps to the 1TB drive. I've had to reboot twice now due to failing services (web services and ssh all become unresponsive) I think due to the scrub failing on the 1TB drive (scrub takes more than 12 hours to get to 97.54% done. I think it's hanging on bad sectors but not sure at all).
All this is to say - I want to replace the 1TB drive, but I'd rather replace it with a larger drive. According to the FreeBSD docs on ZFS, this should be possible, but I'm not clear on if I need to do anything fancy before replacing the drive (e.g. partition replacement 4TB drive as 1TB | 3TB) or which instructions I need to follow ('replace a functioning device 19.3.5' or 'dealing with failed devices 19.3.6').
Any help, advice, or pointers to relevant threads would be most welcome.
