System crash - now shows "no space on device"

[Lisa Kachold]

Hi Joe,

You can check your free inodes via:

# df -i
or via:

# tune2fs -l /dev/sdb1 | grep *Free

*
Boot your system into single user mode:
Is this Fedora? Use F15 or append the word "single" to the end the grub2
command line.

and delete all the files in;

/var/spool/mail/root
/var/log/messages
/var/log/mail*
/var/log/mess*

Look for core files - but until you clear up some space you can't do much
(not even locate).  Did you determine if your disk is mounted read only?
Do you have a hardware controller or any mdadm on the drive?

You can boot into Knoppix and it will not mount any part of the disk as
swap so you can work on the drive after manually mounting it.

You can also use yum or apt-get to remove a package to quickly get some
diskspace free.

Use locate (find-utils) to identify and remove core files, iso's and
Virtualbox images.  But you can't run find or locate without /tmp file
space.

Again, removing the root mail spool (be sure to create it again with "touch
/var/spool/mail/root | chown root:mail /var/spool/mail/root"

# locate core

You can also determine what files were modified 2 days ago:

touch -t 201209172359 dummy
find / -name 'DS*' -newer dummy



Once you have enough disk space free you can boot back into kde.
