I think one of my 4 WD Red 2Tb disks are gone.... i have a ZFS1 raid, and i have an alert from freenas and i make a long smart check and this is the output:
Maybe 3 years later my hdd are gone and i'm thinking about change all disks, if I change one at a time and I'm waiting for it to regenerate, i can change 2 Tb disks to 6 or 8 Tb and finally i have a big pool or ....my idea would be to take advantage to change them one to one for bigger ones and thus to have more space without losing the data of the pool, would it be possible ?
