Logical Volume block size question

[Nyck_1]

I have some oracle mount points that are created from a Raid 5 setup on a P400 raid array connected to an rx6600. For these mount points how can I found out the following:-

what is the block size?
what are the maximum number of blocks that can be read in one read?

use fstyp command.


suxde900 # fstyp -v /dev/vg01/lvol1
vxfs
version: 4
f_bsize: 8192
f_frsize: 1024
f_blocks: 61440000
f_bfree: 19579518
f_bavail: 18355799
f_files: 4975516
f_ffree: 4894876
f_favail: 4894876
f_fsid: 1073807361
f_basetype: vxfs
f_namemax: 254
f_magic: a501fcf5
f_featurebits: 0
f_flag: 16
f_fsindex: 7
f_size: 61440000


here check for fs_bsize

df -g displays the block size of a file system as I have just discovered.

hi,

Information for PA400 can be found using saconfig command. Find the device file with "ioscan -fnkd ciss". Then display current configuration for the card using "saconfig /dev/ciss0" (if ioscan said device was /dev/ciss0).

Regards,

Fred

ls -s file name ( It gives the size of the files in blocks)

Thanks
