今回はzfsではなくて、SMARTさんからメール

ということで、4TBドライブが壊れて来ているらしい。
前回HDD交換した、2018年11月11日からの日記のようにzfs scrubしてみると
# zpool status -v
pool: tank
state: ONLINE
scan: scrub repaired 0B in 0 days 08:34:44 with 0 errors on Tue Oct 20 18:11:32 2020
config:

sdc1 ONLINE 0 0 0
sdb1 ONLINE 0 0 0
cache
sda3 ONLINE 0 0 0
errors: No known data errors
前回とは異なり、ZFSのファイルシステムにはダメージはまだ来ていない。
というわけで、SMARTでのオンラインテスト中
# smartctl -l selftest /dev/sdc

このシーゲートの4TB HDDは、Head_Flying_Hours 29730h+40m+11.535s = 3年4ヶ月だから、もう少し使えるかと思って、だましだまし使ってる
