Hi everybody ! I try to generate a filesystem on a minidisk for NEWS. There are 190000 blocks available and I try to generate 90000 inodes. mkfs /dev/hd7 190000:90000 If I say less than 32000 inodes, the AIX-system will do it, but if I say more than 32000 inodes (iE 90000) I will get 32000 and not one more. thanks for help fozzy --------------------------------------------------------- EDV GesmbH Vieanna/Europe USENET: fozzy@edvvie.at Tel: (0043) (222) 59907 (8-20 CET)

AIX/RT limits filesytems to 32000 inodes, alas. Strangely, both AIX/370 and AIX/PS-2 do NOT limit you to 32000 inodes/fs. That is, they have 4-byte inode numbers.

AIX uses an unsigned short for inode number. This would limit one to 65,535 inodes (2^16-1) except that, for some reason, mkfs only allows signed positive inode numbers. You might think this would allow 32767 (2^15-1) inodes, but mkfs further restricts the number to 32000. News B, at least, forces you to use a single file system for news through its use of hard links, even when you are sure that there will be no cross posting. This makes it tough to keep a full feed. Does anyone know if news C fixes this (I know, I know, wrong group...)? Not an official spokesman for IBM, and speaking for myself. -- Nick Simicich --- uunet!bywater!scifi!njs --- njs@ibm.com (Internet)
