Ripro Backup (Legato)

Index Size and OS restriction

Problem:

The maximum filesize in AIX 4.2.1 is restricted. What if the Legato indexes grow beyond 2 GB?

Explanation:

The structure of the client file indexes (only in Legato 5 and up) avoids operating system restrictions on file size and allows the client file index for a single client to continue to grow.

As the client file index grows, it splits into segments of max 2 GB each. If you want to check the size of a client's file index, enter the nsrls -f command, as in the following:
# nsrls -f /nsr/index/ client-name/db

Example:

root@rtest8:/ 32 > nsrls -f /nsr/index/rtest8/db

Database id 0: /nsr/index/rtest8/db

Now, if you perform nsrck -F each segment of the index structure is checked (means max 2 GB at once) and not the whole db directory at once.
