For example if you took the backup with ufsdump, then use ufsrestore. -- Chris

Can you please let me know what I am expected > to do to preserve its data ? First, redo newfs without the -m option. -m 0 gives you 0% free space... Then, to preserve is too late, you have to restore the data from your backup. # cd /mnt # ufsrestore xvf /dev/rmt/0hn

According to you, I removed my original /opt definition You say you have data in /dev/dsk/c0t2d0s3 that you want to copy into your new /opt filesystem. But then: > # mount -F ufs /dev/dsk/c0t2d0s3 /opt > corrupt label - wrong magic number This means that /dev/dsk/c0t2d0s3 is not a valid filesystem. So it isn't possible that you have data on it. Obviously something you're telling us is wrong. -- Brandon Hume - hume -> BOFH.Ca, http://WWW.BOFH.Ca/ |
