Large File Supported

[aan_1]

We are using the JFS filesystem:
fstyp -v /dev/vg01/lvol1
vxfs
version: 5
f_bsize: 8192
f_frsize: 1024
f_blocks: 512000000
f_bfree: 504518157
f_bavail: 472985773
f_files: 126150272
f_ffree: 126129536
f_favail: 126129536
f_fsid: 1073807361
f_basetype: vxfs
f_namemax: 254
f_magic: a501fcf5
f_featurebits: 0
f_flag: 16
f_fsindex: 10
f_size: 512000000

How to know that this filesystem support the Largefile?

Hi,

without online jfs
# /usr/sbin/fstyp -v /dev/vgxx/lvolx|grep f_flag
f_flag: 16 large files are activated
f_flag: 0 large files are inactive

with online jfs
/usr/sbin/fsadm -F vxfs /file_system_path
the o/p will be largefiles

Large files ARE supported, if you wan't to know if largefiles is active you can use:

[root@sdprbusq:~]# fsadm -F vxfs -v /home
vxfs fsadm: using device /dev/vg00/rlvol8
largefiles

Hi Asrul,

f_flag : 16 shows that you currently support larger file

# fstype -v /dev/vgXX/lvolX
f_flag: 16 = largefiles
f_flag: 0 = no_largefiles


Thanks,
Johnson
