FreeNASのディスクをGUIで交換をする

今回はRAID-Z（RAID5）で運用しているFreeNASのディスクを交換します。最終的には4台交換して容量をアップさせる予定です。

コマンドでも確認

$ zpool status
pool: pool3
state: DEGRADED
status: One or more devices could not be opened. Sufficient replicas exist for
the pool to continue functioning in a degraded state.
action: Attach the missing device and online it using 'zpool online'.

念の為にsmartテストを行う

$ smartctl -t short /dev/ada3

SMART Self-test log structure revision number 1

1 Short offline Completed without error 00% 2410 -

問題ありませんのでリプレースさせます。

リプレース作業

念の為コマンドラインでも状況を確認しておきます。

$ zpool status
pool: pool3
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.

しばらくすると完了予測時間が表示されます。約6時間と出てますが、このあと3時間程度と表示が変わりました。

pool: pool3
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.
scan: resilver in progress since Thu Apr 23 00:29:54 2020

一晩経って状態を確認する

zpoolコマンドでも正常性を確認

$ zpool status
pool: pool3
state: ONLINE
scan: resilvered 424G in 0 days 03:05:15 with 0 errors on Thu Apr 23 03:35:09 2020

念の為gpartでパーテーションも確認します。CLIで交換している人の記事では手動でパーテーション合わせている方もいらっしゃいますが、GUIからの交換ではSWAP領域も自動で取られているようで、問題ないと思います。

$ gpart show /dev/ada2
=> 40 976773088 ada2 GPT (466G)
40 88 - free - (44K)
128 4194304 1 freebsd-swap (2.0G)
4194432 972578696 2 freebsd-zfs (464G)

$ gpart show /dev/ada3
=> 40 5860533088 ada3 GPT (2.7T)
40 88 - free - (44K)
128 4194304 1 freebsd-swap (2.0G)
4194432 5856338696 2 freebsd-zfs (2.7T)

同様の手順で4台交換すれば容量が増えるはず！ですが、別記事にて。
