ex a former 8 gig file systems that has grown to a 32 gig file system shows 2048 as blocksize. It should be around 8192 according to fstyp.
mkfs shows:
mkfs -F vxfs -o ninode=unlimited,bsize=2048,...
fstype shows:
f_bsize: 8192
f_frsize: 2048
wouldn't this hurt performance during processing????
Solved! Go to Solution.

Re: block size of vxfs after fsadm
Whether or not there is a performance penality depends (in part) on the version of JFS you are running. Things have changed between JFS 3.3 and JFS 3.5. See here for more:
http://docs.hp.com/en/5576/JFS_Tuning.pdf
However, the blocksize will be fixed from the time the filesystem was created.

Re: block size of vxfs after fsadm
If the smallest addressable unit is based off of the bsize of the file system. Would the 32gb filesystem blocked at 2048 take more room in memory to address than the 8192.
If there is no difference then why have diffent blocksizes.
Thanks
