i have a filesystem /fs based on lv fslv00. now i use cplv copy fslv00 to fslv01, then i want to create a fs /fs01 on fslv01 and mount it.
then i use smitty crfs, but content of the new mount fs is empty.
so i do the test again, and modify /etc/filesystems manually, this time the target is the same as source.
but i heard of manually modify this file is not recommended, so it there any CLI to create a entry in /etc/filesystems?

Hello,
CLI to create a FS:

• mklv -y'name_of_LV' -t'jfs2' name_of_VG size_in_lp hdisk0
• crfs -v jfs2 -d <name_of_jfs_LV> -m /<mountpoint> -a logname=INLINE -A yes

E.g:
mklv -y'testlv' -t'jfs2' rootvg 1 hdisk0
crfs -v jfs2 -d testlv -m /test -a logname=INLINE -A yes
would create a LV with the name testlv, size 1 LP in rootvg on hdisk0. The crfs creates a jfs2-FS on the previous testlv with the Mountpoint /test with INLINE-Log Option and automatic mount on Reboot (Entry in /etc/filesystems).

HTH,
ku
