  • 1.  AIX filesystem size what is practical

    I have a customer with a V7000 that is around 100TB. We need to create a filesystem for him and he says use the whole thing. I am concerned about what would happen if the system crashes and we need to fsck the filesystem. Initially the OS will be 6.1, but going to 7.1 within a year.

    What is a practical size of a JFS2 filesystem if my worries are founded?

    Can you describe the environment? Will you use virtualization (VIOS, lpars...) What will the space be used for?  What is the raid level of the V7000?

    LPAR, but most of the machine (254 proc, 2TB RAM). No VIOS. The filesystems will be used for end user data files. Currently they have 24TB in several filesystems on the old machine. When we deploy the new machine they want less filesystems to have to do their automated search to find the data they are looking for.
