HP StoreAll Storage - Manual (Page 18)

The Data Retention tab allows you to change the data retention configuration. The file system must
be unmounted. See
“Configuring data retention on existing file systems” (page 147) for more
information.
NOTE: Data retention cannot be enabled on a file system created on IBRIX software 5.6 or earlier
versions until the file system is upgraded.
The Allocation, Segment Preference, and Host Allocation tabs are used to modify file allocation
policies and to specify segment preferences for file serving nodes and IBRIX 9000 clients. See
“Using file allocation” (page 240) for more information.
Creating a file system using the CLI
The ibrix_fs command is used to create a file system. It can be used in the following ways:
•
Create a file system with the specified segments (segments are logical volumes):
ibrix_fs -c -f FSNAME -s LVLIST [-t TIERNAME] [-a] [-q] [-o
OPTION1=VALUE1,OPTION2=VALUE2,...] [-t TIERNAME] [-F
FMIN:FMAX:FTOTAL] [-D DMIN:DMAX:DTOTAL]
•
Create a file system and assign specify segments to specific file serving nodes:
ibrix_fs -c -f FSNAME -S LV1:HOSTNAME1,LV2:HOSTNAME2,... [-a] [-q]
[-o OPTION1=VALUE1,OPTION2=VALUE2,...] [-t TIERNAME] [-F
FMIN:FMAX:FTOTAL] [-D DMIN:DMAX:DTOTAL]
•
Create a file system from physical volumes in a single step:
ibrix_fs -c -f FSNAME -p PVLIST [-a] [-q] [-o
OPTION1=VALUE1,OPTION2=VALUE2,...] [-t TIERNAME] [-F
FMIN:FMAX:FTOTAL] [-D DMIN:DMAX:DTOTAL]
