Block size

Can anybody tell me how to find the block size of HFS and VXFS filesystems .
Any help will be appreciated.

Thanx,

Hi,

you can get with:
fstyp -v /dev/vgXX/lvolX
The line f_bsize tells you the block size.

with the command
fstyp -v /dev/vgXX/lvolXXX

you'll obtain the information connected to the File System and among them the block size

Hi,

try mkfs -m .
You get something like
mkfs -F vxfs -o ninode=unlimited,bsize=1024,version=3,inosize=256,logsize=1024,nolargefiles /dev/vg00/lvol9 524288

And bsize shows you the blocksize.

regards,
Andreas

Sorry,

the fundamental file system block size is shown as f_frsize (not f_bsize).

Another way is to use the 'df' command with the '-g' flag. Examples:

df -g /
df -g /dev/vg00/lvol3
