Hi Colin,

>>Btw would like to check with you guys also.

Would there be any issues or performance degradation if my system have a mixture of mount points with nolargefiles and largefiles running concurrently?

NO, It only enable to support large files,

Cheers,

I don't know about 11.00 but you don't need it to run fsadm, even if mounted.

HI

"...If even one large file is detected on the filesystem being converted, then the fsadm command will not convert the filesystem. Therefore, if it is necessary to convert a large-files filesystem that actually has large files on it to a no-large-files filesystem, the large files must be
removed before conversion..."

http://docs.hp.com/en/940/lgfiles4.pdf

See above largefiles whitepaper which OK's the conversion fron NO largefiles to YES largefiles using the 'fsadm' command but only on the RAW LVOL and only when the file system is mounted and only if there currently are no largefiles.

"...the large files must be removed before conversion..." is clearly stated in the whitepaper.

Note that I could find no publication date on this whitepaper and that it was found in this April 2005 thread:

Sorry, typo

"...file system is UNmounted..."

The white paper says do not run this fsadm command on a mounted filesystem.

Sorry, I do this once in awhile, post an answer to an older thread used in research. Please ignore this closed thread.
