Filesystem is not clean - run fsck

[Carlos Luna]

Hi I'd used freenas about 5 years without any problem. Now I can´t mount my
raid volume and in his sourceforge forums seems they cant help me. Hope this
list is the right list for my issue.

When I try to fsck,I get:
casa:/dev# fsck -t ufs -y /dev/pst0s1
** /dev/pst0s1
** Last Mounted on /mnt/raid
** Phase 1 - Check Blocks and Sizes
