- I just called DEC yesterday on this and they faxed me the solution.
- Normally, to create more inodes you have to drop the number of
- cylinders per group and decrease inode density:
-
- newfs -n -v -c 8 -i 1024 /dev/rrz2g RZ55
-
- However, trying this won't work on RZ57s and RZ58s since newfs says
- you have to use multiples of 16 for the cylinder per group number.
- However, they gave me this which doubles the number of inodes:
-
- newfs -n -v -b 4096 -c 8 -i 512 /dev/rz3g RZ58
-
- The same will work for the RZ57 (substitute RZ57 for RZ58).
