How can I find the filesystem block size in AIX?

I need to check if it is the same as my DB block size.

AIX doesn't use block size, just the record length that should be in your program and fixed or variable length records.

Now way. AIX filesystems have block sizes.

Man mkfs shows

Quote:

-s Size Specifies the size of the file system. Size can be specified in units of
512-byte blocks, Megabytes (suffix M should be used) or Gigabytes (suffix G
should be used). See "Understanding JFS Size Limitations" for more information.

Is this because of the Journaled File Systems in AIX?

Suit yourself!

lsfs -q <fs_name>

Hope this helps.

@tmarikle: What you are talking about is something completely different. This just means that when creating/changing a filesystem you can specify the size of it in multiples of 512 (bytes), Megabytes or Gigabytes. Nothing more, nothing less.
