Manual File System Expansion Pre-4.7.2

Expanding file system via CLI when GUI expansion fails

There is an issue expanding a file system pre-4.7 if stripe groups have been removed but not deleted, i.e. downed manually in the FS.cfgx. Attempting to expand the file system via the GUI will fail with an error stating that the ordinal is out of bounds. To expand the file system using new stripe groups you must expand it manually. This is related to PTR 36626 and is fixed in 4.7.2

Step 1

Label new LUNs using GUI or CLI

Step 2

Stop the file system via the GUI. Changes made via CLI must have the FSM down.

Step 3

Modify the File System configuration file. Examples follow.

________________________________________________________________________

ORIGINAL FILE SYSTEM CONFIG FILE (/usr/cvfs/config/archives.cfgx)

With downed stripe highlighted. This is the group that caused this example to fail.
