Hi all,

Thanks to those responded to my query: David Lodge, Ed, Bill Hassell, Ryan, Eef Hartman, Alex Winson.
All suggest me against using mkfs since it will destroy existing data. As the filesystem in question is of type vxfs, they're also agreed changing the block size will not have much difference in terms of access speed as the actual physical I/O will be handled by OS.

Regards,
Edi

Hi list,

Never did it before. So just to make sure I do it safely.
Without involving backup/recovery of course, can we do it safely in terms of data integrity (no data lost, corruption, etc)? Or will mkfs wipe out the entire data?
Understand the systax would be:
# mkfs -F vxfs -o bsize=nnn <lvname>
