Max file size in HP-UX

[Igor_31]

Hello,
I've set up a new HP server rx2660 with HP-UX 11i v2.

I am faced with a problem of creating file above 2 GB size.

"ulimit -a" shows the following parameteres:

core file size (blocks, -c) 2097151
data seg size (kbytes, -d) 1048576
file size (blocks, -f) unlimited
max memory size (kbytes, -m) unlimited
open files (-n) 2048
pipe size (512 bytes, -p) 16
stack size (kbytes, -s) 131072
cpu time (seconds, -t) unlimited
max user processes (-u) 3688
virtual memory (kbytes, -v) unlimited

...Netheless I cannot create files above 2gb size.

How can i turn on the ability to create file more size?

Thank you very much!

Probably because the file system isn't set for large files:

# fsadm /app
fsadm: /etc/default/fs is used for determining the file system type
nolargefiles


Change it:

fsadm -o largefiles /dev/vgXX/lvolXX

BTW - make sure you update /etc/fstab as well:

Example:

/dev/vg01/lvol2 /var/adm/crash vxfs rw,largefiles,delaylog,datainlog 0 2

Hi,

your filesystem is not configured for 'largefiles'.
You can test it with:
# fstyp -v /dev/vgxx/lvolx |grep -i f_flag

insert your configuration for the x's

f_flag = 0 -> max 2 GB
f_flag = 16 -> max 8 GB

Shalom,

Don't forget the filesystem.

largefiles needs to be enabled there as well.

newfs or fsadm to convert the filesystem.

It is necessary that you run fsadm to modify a filesystem for files > 2GiB (or recreate the filesystem via newfs/mkfs and specify largefiles) but is it not necessary that you enable the largefiles mount option. The mount option in no way enables or disables large files. It certainly does no harm to add this mount option but the mount option doesn't actually make your filesystem instantly able to handle largefiles. Basically, if the mount succeeds with the largefiles argument, the filesystem is largefiles enabled. It is a test rather than an actual enabler.

Now, even if the filesystem is large files enabled, ulimit is set high, and quotas are not in play or set very large, it is still possible to hit the 2GiB barrier if the application itself was not written to take advantage of 64-bit file offsets.

Thanks to all. Your answers were very helpful! I've fulfilled your recomendations!
