初めての zfs (ubuntu 19.10）amazon prime video をみる + 音声入力

簡単にはいります,　でインストについてはqiitaでは説明しませんが
以下に インスト過程の　スクリーンショットを載せてます
https://hatahata-linux.blogspot.com/2019/12/ubuntu-1910-zfs.html

UEFIな　PCには, 当然入ります,
BIOSな　PCにも はいります,
古いサーバーの **raid 0**にも　入りました。

下はわずか80GBの2.5インチ　HDDに入れたものです
その後　ddで　80GBのを　160GBのHDDをクローンすると　160GBでもきちんと動きます。　しかも　別のBIOSなPCにその160GBを取り付けてでもです（fujitsu->thinkpad）、　便利です。


```
さらに　「sata アダプターをつけたm.2 ssd ngff」 にクローンすると
# hdparm -t /dev/sda7
/dev/sda7:
 Timing buffered disk reads: 822 MB in  3.00 seconds = *　273.55 MB/sec　*
という高速度が得られます
```


自分のモニターは縦置きで

```
したがって
# fdisk -l /dev/sda
は
Device     Boot   Start       End   Sectors  Size Id Type
/dev/sda1  *       2048    104447    102400   50M 83 Linux

をみると世界で　白人の支配下に全く入ってなかったのは　我が日本だけですね-
（タイは　イギリスとフランスの緩衝地帯だった理由で　手が入ってない）

|https://ja.wikipedia.org/wiki/ZFS によると|
|:---|
|ZFSは、主にオラクルのOracle Solaris上で実装されている**128ビット**・アドレッシングを特徴とするファイルシステム。今まで Solaris (SunOS) で用いられてきた **Unix File System (UFS) の次世代ファイルシステムと位置づけられている**。|


| **amazon prime video もみれます**
|:---|
|https://www.google.co.jp/chrome/ から　
|google-chrome-stable_current_amd64.deb　を
ダウンロードし|
|# dpkg -i google-chrome-stable_current_amd64.deb
だけです|


fcitx-mozic をインストしたあと im-config　して再起動すると　日本語もOKです。

自分は USB　ハードディスクにインストしました.
(1st　は　m.2 ssd nvme です）

にあるように
 You can get Chrome from https://www.google.com/chrome/browse...top/index.html 
https://www.google.com/chrome/thank-you.html?statcb=0&installdataindex=empty&defaultbrowser=0
にて
google謹製の
google-chrome-stable_current_amd64.deb

dpkg -i google-chrome-stable_current_amd64.deb
でいい
##これにてgoogle document の音声入力もOKだよ

ddで　８０GB　HDDを　160GBHDDにクローンできたが、
root領域をどうすれば拡張できるのだろう？

gparted は　btrfsには通用するするがzfsには　あかんたれだ。
ムズイ！

自分のは
zpool status
  pool: bpool
 state: ONLINE
status: The pool is formatted using a legacy on-disk format.  The pool can
	still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'.  Once this is done, the
	pool will no longer be accessible on software that does not support
	feature flags.
  scan: none requested
config:

	NAME        STATE     READ WRITE CKSUM

そして
zpool online -e rpool sda7
は通るが　なんの変化もない感じ
