該如何調整lowmem大小?
« 於: 2012-02-16 09:29 »
dear all:
    MySQL DB在前幾天發生了process被kill掉,而造成DB不同步的慘劇,按message log所記錄的錯誤,在網路上google了很久,找到如下列網址所述,lowmem在32位元的作業系統只有最高到880M。而我的問題是我的這台主機 Lowmem total 為什麼只有498M(如下),
    主機不在公司內,也就是說我摸不到主機,就算主機就在我面前,如果更換的過程不順利,比如說改了後發現網站找不到資料,連不進資料庫,是不是表示php也要跟著改,是不是~~~~等零零總總的問題,這不是目前的我能解決的,會變成為了解決一個不大不小的問題,而造成更大一個不可知的問題來。
    還有公司內的其它主機和發生lowmem total不到正常數值的這台主機,用的cpu,os版本,kernel都一樣,為什麼其它主機都正常,就那麼一台發生問題,這是不是表示是存在著一個不用換kernel也不用換os的解決辨法呢?

就算找回 880M, 也解決不了可能會 OOM 的問題吧.
想不出不能換到 hugemem 版本 kernel 的原因?  (其實換到 64 位元才算最好的解決方法吧)

主機不在公司內,也就是說我摸不到主機,就算主機就在我面前,如果更換的過程不順利,比如說改了後發現網站找不到資料,連不進資料庫,是不是表示php也要跟著改,是不是~~~~等零零總總的問題,這不是目前的我能解決的,會變成為了解決一個不大不小的問題,而造成更大一個不可知的問題來。
還有公司內的其它主機和發生lowmem total不到正常數值的這台主機,用的cpu,os版本,kernel都一樣,為什麼其它主機都正常,就那麼一台發生問題,這是不是表示是存在著一個不用換kernel也不用換os的解決辨法呢?

不好意思,鵝原先沒看清楚,您的機器是有48G(鵝看成480M了 :-[),如果是這樣應該是kernel把lowmem挪給PAE用了,解決的方法有幾個,換跑X86-64當然是最徹底的(從此擺脫限制,但您有其它考量),其次如果是在VM環境下減少Hypervisor assign給這個guest的RAM也行,最下策是換跑只支援Highmem 4G的kernel(但這麼一來4G以上的RAM就全部用不到了 :P),其實重點就是降低PAE佔用的lowmem而已(PAE一般建議最多用到16G的機器,再上去還是換X86-64吧 :P :P)....

除了PAE啟用外,還要選擇記憶體分配方式不然預設也是3G/1G  high/low mem
所以基本上要自行compile kernel , 預設的rpm套件裡似乎都是3G/1G
可以設成2G/2G 1G/3G ,依需求
但超記體超過4G以上後,如48G這樣,low mem也是3G,而不是12G/36G,而是45G/3G,印象中是主要拿出4G的空間 1G做為45G的管理分配使用,3G才是為low mem使用
另外目前所看到的問題32bit中,mysql在單一process存取大量記憶體buffer cache時,也會有3G的使用問題,不過這又是另外議題了
如twu2所說64bit才是最終的解決方法

所以現在low mem的總量會是498M,是因為先前有人重新compile kernel時,把low mem的上限調整成了498M嗎?
否則為什麼公司其它顯示為同kernel版本、同OS的機器,它的low mem的總量都有800以上呢??
謝謝~~~

不是誰把lowmem設成498M,而是PAE kernel會用掉一部份lowmem(印象中每16G就要128M,那就是為何會有超過16G的機器還是忘了PAE的說法 :P),所以RAM越多的機器跑32bit+PAE時lowmem反而會越少(標準的kernel lowmem就只有1G,3G/1G要另外patch,而redhat系列比較舊的版本才有那個patch,新一點的版本要DIY :P),詳細的說明redhat的knowledge base就找得到了 :P :P....

會不會是開機有設定了kdump , 檢查一下menu.list or grub.cfg grub.conf 的設定 , 我記得這個有設定也會先佔一部份, 不過我忘了是low還是high mem

free -m 是 mb 單位吧 ...
所以你的確有 48G 阿
不然你 cat /proc/meminfo

你有用到 xen 嗎 ?
沒用到盡量就別用 SMP 字眼的 kernel
這些給 xen 用的 kernel 本就對記憶體有限制
你又重新編譯過 ... 哪裡沒對準好 ... 問 redhat 恐怕都叫你重灌喔
