Hello all,
System: Solaris 10 6/06 (Sparc), fully patched.
I need to transfer all our homedirectories with lots of small files to a
new volume (ST6140 RAID 5, 1.3TB). Default number of bytes per inode
results in way too few inodes.
So I want to lower the nbpi with the -i option of newfs. Using 8192 or
any lower number for nbpi does not have any effect on the number of
inodes in the resulting FS, as to see in the output of mkfs -m
/dev/rdsk/cXtXdXsX... What is going wrong?
Below, first the result of newfs with no options (default nbpi 1048576
for FS greater than 1TB, according to manpage), second newfs -i 8192 -
both produce nbpi of 997778 !
Thanks in advance for assistance.
Paul
