6.1 HP IBRIX X9000 Network Storage System File System User Guide (TA768-96061, June 2012)

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 138) for more
information.
NOTE: Data retention cannot be enabled on a file system created on X9000 software 5.6 or
earlier versions. Instead, create a new file system on X9000 software 6.0 or later, and then copy
or move files from the old file system to the new file system.
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 X9000 clients. See “Using
file allocation” (page 195) 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]
