Description olivier 2011-11-18 10:30:13 UTC

Installing FreeBSD-9.0-RC2-amd64-dvd1.iso on a VM with an hard drive less than 6 Go failed.
Tested and reproductible on a VM configured with a 4Go or 5Go hard drive as example.

During install process I choose these distribution sets: ports and src only.
And I'm using guided partitioning / Entire Disk / All Auto

The installer failed during archive extraction of ports.txz (at about 88% progress of this file extraction) with this kind of message:

Error while extracting ports.txz:
Can't create
'usr/ports/XX/YY'

And on the background there is this message:
..on /mnt: out of inodes

Because these distribution sets (ports and src only) consume only 2.7Go of disk space, it should be possible to install it on a 3Go hard drive.

Fix: 

Using a minimum of 6Go hard drive fix the problem.
How-To-Repeat: Installing distribution set ports and src on a VM with less than 6Go hard drive.

Hi,

I've did some tests: The number of inode after a fresh install of
9.0-RC2 is half the number of inode after the fresh install of a 8.2.
I've install a 6Gio hard drive, MBR, no swap partition and all in /
(under VirtualBox).

After a fresh install of 8.2 (=ABuser=BB insall):

[root@vm]~#df -i
Filesystem  1K-blocks    Used   Avail Capacity iused ifree %iused  Mounted =
on
/dev/ad0s1a   6090038 451176 5151660    8%  12509    788257  1%   /
devfs               1       1       0   100%       0     0  100%   /dev

number of inode =3D iused + ifree =3D 800766


After a fresh install of 9.0: (base,kernel,games,lib32)

[root@vm]~#df -i
Filesystem  1K-blocks    Used   Avail Capacity iused ifree %iused  Mounted =
on
/dev/ada0s1a   6184164 684012 5005420    12%  13409    412829  3%   /
devfs               1       1       0   100%       0     0  100%   /dev

number of inode =3D iused + ifree =3D 426238

This is a big problem: It prevent to extract or update the port tree=85

Thanks,

Olivier

  Reduce NFPI by half to keep the default number of inodes the same with
  the now default 32K/4K filesystem the same as the number of inodes in
  the previously default 16K/2K filesystem.
