Blocksize of Filesystem

[Amit Manna_6]

Can anybody tell me how to determine the blocsize of HFS or Vxfs

Hi,

You can retrive the Blocksize of Filesystem using fsck command.

Please check the link for more options

Hi Amit,

You can use fstyp(1M) command.

Find the type of the file system on a logical volume, /dev/vg00/lvol6:

$ fstyp /dev/vg00/lvol6

Find the file system type for a particular device file and also information about its super block:

$ fstyp -v /dev/dsk/c1t6d0

For explanations for the outputs, please refer manpage for statvfs(2).

Anshu

Hi,

I'm no sure about your question, but the magic number is 512.

Pls take a look in "man df"

Rgds.

Hi,

I see that there is confusion on this point.
In order to explain take the following sample:

# fstyp -v /dev/vg00/lvol3
vxfs
version: 3
f_bsize: 8192
f_frsize: 1024
f_blocks: 143360
f_bfree: 94588
f_bavail: 94588
f_files: 2432
f_ffree: 1073792296
f_favail: 1073792296
f_fsid: 1073741827
f_basetype: vxfs
f_namemax: 254
f_magic: a501fcf5
f_featurebits: 0
f_flag: 0
f_fsindex: 5
f_size: 143360

Blocksize of filesystem /dev/vg00/lvol3 is f_frsize: 1024, therefore 1Kbytes.
f_bsize: 8192 is the max blocksize which is possible to set but the actual is f_frsize!

I hope this helps you.

Best regards,
Ettore

I have seen many members donot close the thread by telling if there problem is solved or not. This really leaves respondants guessing where there reply was worth or not. Request question asking members to always close the loop, if the solution provided is not worth, then please put 0 (zero) points, else provide appropriate points.
