Operating Systems HP-UX 2GB file size limit Post 302572251 by bkimura on Wednesday 9th of November 2011 12:20:06 PM

Thanks for reaching out.
Code:
# uname -a
HP-UX corvette B.11.11 U 9000/800 1756503870 unlimited-user license

I'm primarily a Linux administrator and don't dabble much with HP-UX so if you need additional info, please let me know.

The HP-UX server is attached to EMC storage. Our Linux servers were previously backing up to a legacy Sun Solaris server but we've run out of space there so I'm trying to shift the scripts to now backup to the HP server. I've created the logical volume and filesystem from scratch. As mentioned, everything seems to be working as expected with the exception of using dump from Linux to this filesystem. The Linux servers are using the dump options "0uf". I've tried 0auf to no avail. Thanks again for reaching out.

Keep in mind that the exact same script works flawlessly to both a Solaris server and another Linux server. As soon as I change one of the variables to point to the HP-UX server, it craps out after 2GB every time. The dump is over SSH. I've also tried RSH but got the same results. Thanks.

Proof that the filesystem in question does in fact support large files:
(I've also scp'd an 8GB file from the same Linux server to the filesystem)
Code:
corvette]:/os_dumps/blades # dd if=/dev/zero of=8gb_file bs=8k count=1048576
1048576+0 records in
1048576+0 records out
