2GB File size limit

[A.W.R]

Hi,

Please can some one clarify what the current file size limit is under HP-UX 11i. I have been told it is 2GB?

Thanks
Andrew

Andrew,
the 2GB limit only applies to certain commands (tar ...) and disk setups.

For disks you can enable largefiles by using SAM -> disks > Filesystem.
Also check with fsadm /filesystem

Hi,

The filesystem option "largefiles" is require for file over 2G. Otherwise, it will limited to 2G.

GOOL LUCK!

Shalom Andrew,

Not exactly true.

If the filesystem was nor formatted for largefiles the filesystem will not permit files bigger than 2GB

If newfs -o largefiles was used to create the filesystem then the size limit is 128 GB or 2 TB, but much bigger than you'll need.

fsadm can be used to convert a filesystem from not permitting largefiles to permitting them.

Hi,

definitely no!
2GB is the limit if the option 'largefile' is not set for a filesystem.
Where's the next limit? I've files with 18GB.

The 2Gb filesize limit was removed many, many years ago when HP-UX version 10 was released. With current versions of HP-UX (11i) the limits are 128Gb for HFS filesystems (hardly ever used anymore), and terabytes for VxFS filesystems. Note that files larger than 2Gb must be backed up with modern utilities. tar, cpio, etc are not compatible with large files and are ill-suited (low performance) for dozens to hundreds of Gb or more.

One potential "gotcha" even if the filesystem is largefiles enabled, ulimit is large, and quotas are not in force is the application itself. If you are running a legacy application, the application may have built-in limits.
