This is such a classic problem that I hesitate to raise the
question. The df below shows that the usual suspects for root partition
being full are broken out. The / partition is 500 Mb. In the past I have
only used about 50 Mb.
# df
Filesystem 1K-blocks Used Available Use% Mounted on
rootfs 474440 474440 0 100% /
udev 10240 0 10240 0% /dev

/dev/sdb13 192243928 58177436 124300984 32% /storage
I verified that root is indeed full by trying to copy a file to it.
I ran:
# find / -type f -size +100M -exec ls -lh {} \; | awk '{ print $9 ": " $5 }'
All files that were over 100 Mb were located in broken out directories
except this:
/sys/devices/pci0000:00/0000:00:06.0/0000:01:00.0/resource1: 256M
/sys/devices/pci0000:00/0000:00:06.0/0000:01:00.0/resource1_wc: 256M
This is peculiar and a suspicious size. So I go its directory to
verify:
# ls -la | grep resource1
-rw------- 1 root root 268435456 Jul 29 08:13 resource1
-rw------- 1 root root 268435456 Jul 29 08:13 resource1_wc
but:
# file resource1
resource1: ERROR: cannot read `resource1' (Input/output error)
I ran $ du -h on all the directories mounted on / and not broken out,
and their total came to 350 Mb. This strikes me as big, but still is not
greater than the partition size.
