advfs 怎樣看block size

HPUX:fstyp -v /dev/vg00/lvo*|grep bsize;df -g

AIX:dumpfs /dev/lvo*|grep block

Solaris:fstyp -v /dev/* |grep bsize ;df -g

Linux:dumpe2fs /dev/sda*

但是tru64要怎樣才能知道目前的file system的block size是多少,因為我用 mkfset 都沒有可以指定block size的參數

所以我也不知道我create 的file system block size是多少

advfs 怎樣看block size

你指的blocks size 是Rblks Wblks??

這兩個又有什麼不一樣?

advfs 怎樣看block size

Hello Joey:



Rblks is the maximum number of 512-byte blocks read from the volume at one time, and

Wblks is the maximum number of 512-byte blocks written to the volume at one time. So if

Rblks is 256 and Wblks is 256, it means read

block is 128KB/max and write block is 128KB/max,

too.



man showfdmn has more info for your ref.



Cheers

Danny
