Just swapped out discs in my ZFS storage array

It was about time. I still had a bunch of discs made in 2015. The last swap was discs made in 2018-2019.

I routinely monitor my zpool scrub reports. All clean.

Periodically I run $smartctl on each disc.

Error corrections were accumulating.

These discs were getting old so I pre-emptititvely swapped them out, but rather than 4gb SAS drives, the new ones are 8gb SAS.

You reminded me to check, and... my local files are fine.

edit: This is after one year of constant use in my desktop machine.

maybe at least yearly run $ smartctl on each of the individual drives. I use the output of smartcll to decide when to swap a drive i.e. before the errors hit zfs. I also run smartctl on new drives to see:

a) how old they are

b) if they are really new

(that said i try to buy from trusted sources but amazon has 3-rd party vendors as does newegg for drives)

I avoid Amazon and Newegg like I would the black plague. B&H has never let me down, nor has Microcenter.

I also have a nice GUI for smartmontools called GSmartControl that lets me see the data:
