no inodes free on root?
Louis Bertrand
When I try to create a file, dir or symlink on / (root), I always get the
same error message:
"/: create/symlink failed, no inodes free"
I did a fresh install of 2.5 April 16 i386 snapshot using the floppy to
boot
and ftp from a local server. This disk previously was used in my pentium
OpenBSD box, but the controller is different (AIC-7770). The machine is a
intel 486 vesa-localbus.
I su to root to try all these:
# cd /
# touch junk
# mkdir junk
# ln -s /home/louis junk
Users attempting programs like chpass also get the same error.
I have no problem with other partitions on the same disk, or the other
disk.
I can't get the Adaptec controller (AIC-7770) to give me the CHS for the
disk, so I a going to try another fdisk (2.4, FreeBSD or M$) to see what
they say, in case this is a BIOS f-up.
Scary details below.
Thanks

Inodes and fdisk have little, maybe even nothing to do with each other.
Your problem is almost certainly due to the fact that your / partition
has too many files on it.

Try 'df -i', and see what your "%iused" field is saying for "/". chances are
that you have /tmp, or even /var/tmp on "/", making it run out of inodes.

I don't use / for much other than system stuff, /etc and mount points:
beastie# df -i

With the system set up this way I was able to get and unpack the ports
tree and build ssh, so the system isn't crippled...

Don't know what happened...
I booted off the install floppy and ran fsck_ffs -f (the file system was
marked clean). fsck coughed on phase 5, free count wrong in superblock.
I answered yes and it's fixed. I rebooted and it's OK now.
The question is: how did the filesystem get broken on a fresh install?
I'll try another machine tomorrow to convince myself it was a fluke...
Thanks
