If properly patched, the implementation limit (for your system 11.00) on size for a single logical volume (and thus file system)is 16777216 MB (~16TB).

# man lvcreate

Do a custom patch analysis on your system and download the latest patches available for your system. You can do this with ITRC custom patch analysis:

Hi Shiju,

Are you sure on that 16TB limit?
A properly patched 11.0 with JFS 3.3ver4 is only 1TB. For 11i JFS3.3ver 4 limit would be 2 TB.

Alberto - see the following link:

HTH,
Jeff

OK - let me explain further.
Although the LV limit is 16TB, the filesystem & therefore file size limit IS 1TB for 11.0 & 2TB for 11.11 (11iv1).

Rgds,
Jeff

Jeff, I think you are right about the 2TB/1TB vxfs file system limitation on 11i/11.00 OS. 16TB is the theoratical value given on the man pages for LVs(lvcreate) and not proved on the Labs. The vxfs version 5 man pages (mkfs_vxfs) says it can support up to 32TB of file system size! But in practical, the version 5 (vxfs) supports only 4TB file system and 2TB file size max.

Man pages does create some confusion some times, but as I said in my original post, it's the *implementation limit* ! =))
