Re: HOWTO: Move FreeBSD to a new hard disk

Hi, Jason
First thanks very much for your kind advice.
It seems it is not the problem of IDE cable or thermal. For I waited it cool down and use a working IDE cable, and the same error comes.
And I also enter into single user mode and issued
#fsck -p
The result is the known bad partiton show the same error message:
ad0s2g had error reading fsbn 14498.... The following file system had UNEXPECTED INCONSISTENCY...
So, it seems the fsck -p doesn't work here.
Anyway, I tried the way you said"drivecopy the known bad partition by itself". But it seems I can not do it. For when I issue the command #mount -a, I got error message:
Warning, R/W mount of denied. File system is not clean-run fsck...
Anyway, my guess is that there are some bad partitions in my two drives (IDE HDDS) starting to fail. And the data on them are not retreiveab le any more. A little luck of me is I have a third drive at home, with everything same as the bad drives, except the data on it was 1 month old, for I used it for a full backup one month ago.
Based on those experience, I have a couple of questions here
1.Is it worth to use those two bad drives again and reinstall a simple system on it and drivecopy.sh everything from the third drive to it? Or just discard those bad drives, in case cause my third working drive fail together?
2.How many time of drivecopy.sh can be used on a new HDD before this HDD worn out and can not be safely used any more?
3. I guess a weekly back up by using drivecopy.sh is a little bit too hard on HDD.
But I would express here that drivecopy.sh is a brillant method to move whole FreeBSD system from one drive to another. No doubt at all. The only concern here is whether there is any limit times you can utilize drivecopy.sh on a HDD.
4. Any recommandation on what medium to use to back up a small business server, with not big traffic database (mysql) and a website hosting.
Best regards
Jennifer |
