 large files? I've installed a samba share on an aix box for the dba to test some backup stuff (doesn't have enough space on the intel box). I created the file as a JFS2, large file enabled, then also changed /etc/security/limits setting fsize=-1 for that user. Restarted samb and things look ok, however the file stops growing at 64GB. I know that's a limitation number, but with all I had done (above) I thought I was past this number. The file size is about 111 GB. Oh, creating the filesystem I maxed out NBPI and the next setting (put both parameters to the highest value). Am I missing something or is the 64GB a real hard limit? Mike      |

What does lsfs -q show you? There is no "large file enablement" for jfs2 as all jfs2 filesystems are large file enabled by default. Also with jfs2, the size of a file is limited to the size of the filesystem. I believe jfs2 is 6TB. Also with jfs2 there are no NBPI settings, only a block size (I doublechecked on my 5.1 and 5.2 servers just to be sure). To me it sounds like you still have a jfs filesystem set up, which explains the 64GB file limitation. ---Phil |

I rebuilt the filesystem and now everything is ok. Thanks for everyone's help! Mike |
