Thanks for your help.
Yesterday I did a yum update, so I have all the latest in the CentOS yum repo.
I updated the kernel to centosplus, and the partition did not mount.
I installed elrepo's repo and #yum install kmod-ufs --enablerepo=elrepo , and the partition does not mount
I a using the comand
# mount -t ufs -o ro,ufstype-44bsd /dev/sda3 /mnt/bsd
mount: wrong fs type, bad option, bad superblock on /dev/sda3
# dmesg | tail
ufs_read_super: bad magic number
Is it possible that installing CentOS corrupted my bsd partition?
Any other suggestions to get data off this partition? I can re-partition when I get the data. I do not need this partition to stay a bsd partition.
