mkfs and newfs failure

[Nate Arnold]

I am trying to create a 4TB file system on HP-UX 11.23 system. I can create the volume group and logical volume but get the following errors.

zeus2:/ # newfs -o largefiles /dev/vg_flash/rlv_flash
newfs: /etc/default/fs is used for determining the file system type

Hi,

------------------------------
mkfs -F vxfs -o largefiles /dev/vg_flash/lv_flash
---------------------------

mkfs requires char. special file /dev/vg_flash/rlv_flash

just make sure /dev/vg_flash/rlv_flash is created or not.

# ls -l /dev/vg_flash

Did you do a ioscan on the disks and verify that the disks are ok. Also check your syslog.log file.

How about your patch level.

May be you need latest Vx patches for file systems bigger than 2TB.

Please check the below patch.

The revised mkfs command still doesn't work.
zeus2:/root # mkfs -F vxfs -o largefiles /dev/vg_flash/rlv_flash

What version of JFS you are using? You need atleast JFS ver. 3.5 running on HP-UX ver. 11.23 in order to create a filesystem > 2 TB.

[Nate Arnold]

I am running VXFS 4.1

According to the following HP doc. 2TB is a limitation of HP-UX 11.23
