Re: Block size

Hi,

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

Re: 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

Re: 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.

Re: Block size

Sorry,

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

Re: Block size

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

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