ibrix_fs
Creates, extends, and manages file systems.
Description
ibrix_fs is used to:
• Create a file system from physical or logical volumes.
• List information about file systems (including snapshot file systems).
• Extend a file system by adding new segments.
• Delete a file system.
• Migrate segments to another file serving node.
• Enable or disable export control on a file system.
• Disable 32-bit mode on a file system.
• Assign or unassign a standby server.
Synopsis
Create a file system
Before creating a file system, determine the mode for the file system and whether data tiering
should be used:
• 32-bit or 64-bit mode. If all file-system clients (NFS, CIFS, and X9000 clients) run 64-bit
applications exclusively, create the file system to use 64-bit mode. If 32-bit applications are
in use, create the file system to use 32-bit mode, which is the default. (A file system created
in 32-bit mode can be converted to use 64-bit mode by disabling 32-bit mode.)
For 64-bit mode, there is no restriction on the maximum number of segments allowed per file
system. For 32-bit mode, the maximum number of segments allowed per file system is 255.
You can set the maximum number of segments allowed when you create the file system.
• Data tiering. A data tier is a group of one or more segments. Tiering is the ability to
automatically migrate files from one tier to another within the same file system. Tiering is
optional and it is turned off by default; however, you can enable it when creating or extending
a file system.
To create a file system, execute one of the following ibrix_fs -c -f commands.
Create a file system with the specified segments:
ibrix_fs -c -f FSNAME -s LVLIST [-t TIERNAME] [-a] [-q] [-o
OPTION1=VALUE1,OPTION2=VALUE2,...] [-t TIERNAME] [
The command creates the file system using the segments specified in LVLIST. The round-robin
method is used to assign segments to file serving nodes.
Create a file system and assign the specified segments to the specified file serving nodes:
ibrix_fs -c -f FSNAME -S LV1:HOSTNAME1,LV2:HOSTNAME2,... [-a] [-q] [-o
OPTION1=VALUE1,OPTION2=VALUE2,...] [-t TIERNAME]
The command creates file system FSNAME and assigns specific segments (LV1, LV2, ...) to specific
file serving nodes (HOSTNAME1, HOSTNAME2, ...). The first logical volume listed becomes the root
segment for the file system. The round-robin method is used to assign segments to file serving nodes.
