Fsck operations
on November 19, 2005 – 10:36 pm 4 Comments
The following is a collection of examples using fsck command. It is important to unmount VXFS before running fsck on Veritas filesystem.
to fsck a Veritas FS:
fsck -F vxfs /dev/dsk/c2t2d0s0
to do a full fsck of Veritas FS:
fsck -F vxfs -o full /dev/dsk/c2t2d0s0
to assume “yes” response to prompts”
fsck -F vxfs -y /dev/dsk/c2t2d0s0
to scan and automatically correct all local non-Veritas mounted filesystems:
df -k | fgrep "/dev/dsk" | awk '{print $6}' | while read line
do
fsck -y "$line"
done
to scan and automatically correct all local
non-Veritas unmounted filesystems:
cat /etc/vfstab | fgrep "/dev/dsk" | awk '{print $1}' | while read line
do
fsck -y "$line"
done

I was using the “Erase Free Space” on my Late 2009 MacBook (10.6.3 Snow Leopard) with a 500 GB hard disk. I had to cancel the operation before it was done, and now I have less than a gigabyte free. How can I regain the rest of my >100 GB free space that I had before? Thanks in advance, I really don’t want to call AppleCare.
