On the Global: Create a new filesystem with INLINE log, like all other filesystems in the WPARs:
# crfs -v jfs2 -g<VG_name> -a size=<size_GB>G -m<mount_point_into_Global> -Ano -prw -a agblksize='4096' -a logname=INLINE -u<WPAR_name>
# crfs -v jfs2 -g'datavg' -a size=6G -m/wpars/wpar10/oracle/wpar10/admin -Ano -prw -a agblksize='4096' -a logname=INLINE -u 'wpar10' # mount /wpars/wpar10/oracle/wpar10/admin
In the WPAR: Add in /etc/filesystems, an entry for the relative path of the filesystem (mount point into the WPAR):
/oracle/wpar10/admin: dev = Global vfs = jfs2 log = INLINE mount = false type = r6db10 quota = no account = false
# crfs -vnamefs -d /var/core/wpar4 -m /wpars/wpar4/var/core -u wpar4 -Ano -prw
