Check the corresponding entry in /etc/fstab where all file systems should be mentioned that you want to be mounted at system startup. For example, a proper line would look like this: # Device Mountpoint FStype Options Dump Pass# # ----------- --------------------- ------ ------------- ----- ----- /dev/ad0s1f /usr ufs rw 2 2 Check device names. Depending on how you're accessing disks, the name could also be ad0f, ada0f, da0f or something else. Also keep the correct terminology: FreeBSD mounts UFS partitions, not slices. A slice contains a partition carrying a file system, usually UFS. > and second question is my mysql is in /var slice if /var is not mout can I > access mysql being root and chek all databases also can read log file on > /var No. You can't access files inside a file system that isn't mounted (exceptions: forensic analysis, or performing a device dump). > third question is can I mount any unmount slice by using just fsck :) No. You can only mount file system that are marked clean. To accomplish this - yes - running fsck for the device (or the mount point, if listed in /etc/fstab) is required when the device has been uncleanly mounted previously. To mount all file systems, use "mount -a". Also you should _not_ fsck a mounted partition. Unmount them first (if required), run fsck, then mount. In worst case, boot from a live system CD or DVD or USB stick and issue the fsck command from there (really, just worst case scenario, you shouldn't need this in the first place). -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
