Hi,
Well block size is very important under RDBMS workloads, since if the
database block is smaller than the fs block size, the operating system has to
perform a read of the rest of the fs block on every database write operation,
which are always synchronous on Oracle, and scattered under normal OLTP
workloads. On other types of files this depends more on the individual size of
files, and the disk space that you want or not to waste.
About cluster size, I really do not know. It might be related with the
locking necessary to the cluster filesystem.
Please do correct me if I am wrong. Anyone?
Regards,
Luis Freitas

Hello ocfs2-users,
I have 2 questions:
1. I forgot the block size and cluster size that I chose
during formatting of the drive. Is there any way I can find it out
afterwards?
2. And what's up with the block size-cluster size anyways? I could
find any in-depth information regarding those parametres. what is
it?
When I tried using the default settings my disk space was being used
twice as normal.
I am using a RAID 5 shared storage device (iSCSI) with the stripe
size of 64KB - what should I choose?
