檔案系統透明壓縮

文章【Palatis】 » 週四 12月 28, 2006 2:25 am


Reiser4 + cryptcompress ROCKS!

我暫時先讓他壓 /usr 跟 /opt 兩個程式檔的主要來源,還不知道會不會爆炸。
備份下來的東西先留著別刪掉吧...

磁碟的反應速度快很多,也許是因為 nb 的硬碟本來就比較慢,配上相對快的 cpu,壓起來剛剛好!
如果你的 gentoo 是作 cpu intensive 的工作,就別搞這個了!
「從麻雀之城回來的時候,被問到『你要大的藤箱還是小的藤箱?』為此煩惱不已。大家都有過這種煩惱吧?」
「是啊是啊!大的藤箱可以放很多東西覺得很划算,小的藤箱小小的裡面也許放著很不錯的東西,真的很難取捨阿!」
「靠這個就能告別這種煩惱『中型的藤箱』!」
「好厲害!」
「不要再煩惱大小的問題了,現在還贈送可以煮出鐵質,增進健康的鐵銼刀。」
「這是一定要買的!」
「我要一個!」

太感謝了
看來是個筆電救星
不過, 這個 beyond-sources 到底 patch 了什麼? 有點怕怕

嗯...
btrfs進官版kernel了 (2.6.29)
Linux領域一直缺少一個"好的"可以壓縮的檔案系統現在終於有了
雖然還是有點實驗性質的東西...
不過可以進官版kernel就代表已經有一定的品質了吧?

準備把portage tree等不重要的東西往裡面塞

今天試了一下btrfs的壓縮功能
一開始我很天真的把一個4.2GB的tar放進去...
結果根本沒被壓縮...
btrfs會用某個演算法判斷要不要壓縮...可是詳情不太明白
沒辦法只好把那個tar的內容展開...
發現只用了1.9GB...效果似乎還能接受...
雖然同樣的檔案用reiser4的gzip壓縮只要花1.7GB

btrfs的fsck工具還很陽春...沒有支援完整的fsck.*的介面
所以開機的時候自動fsck會失敗 = =
