Can I boot from the FreeBSD boot CD and avoid mounting anything on any of the hard drives at all? (That's not a problem in this case, since the root is on a different drive, but if I ever had to replace the drive containing the root I'm just wondering how to go about it.) Sure... just use the live disk. As long as you can access the necessary /dev entries from the CD, you can copy it. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Re: What's an easy way to replace a drive?
Anthony Atkielski wrote: The continuing problems I'm having with my SATA drives seem to center on only one of the two drives, /dev/ad10, and since both drives are identical (Western Digital WD1200JD 120-GB SATA drives), this is a good indicator that the drive itself might be failing. So I've decided to spend $83 and buy a replacement drive to see if that fixes the problem. Now, what's the easiest way to replace the drive? The drive I want to replace contains only /var and /tmp. Are these mounted in single-user mode? I was thinking perhaps I can just replace the drive, set up identical slices on the new drive, then restore /var and /tmp from the latest backup. Can I restore from tape in single-user mode? I don't have any extra connectors to which I can attach this drive without removing one of the other drives, so I'm looking for a way to fix it up by just removing the old drive and putting in the new one, without the need to have both old and new drives online at the same time. You can back up to tape and restore in single user mode.

I have indeed performed the newfs and can now mount /dev/da1s4f. Would it be possible to use growfs to add the new slice to /usr? It is possible to use growfs, but in your case - more complicated, as you have /usr and the new /usr in two different slices. You'd have to resize the slice with fdisk, then use disklabel and growfs. If not, I will follow your instructions in this email. Thanks again. Robert On Wednesday 19 May 2004 08:17 pm, [EMAIL PROTECTED] wrote: When I tried using bsdlabel without any options I got an error.

Re: Backup Server

I would like to setup a backup server so that when the main server goes down the backup server takes over its job. Could some one please tell me the best way to setup a backup server and also suggest some good documentation. In order to keep the data synchronized, you could possibly used some sort of shared scsi or fibre channel drive/array. You'd have to write a script that would run on the backup and tell it to mount the drive and startup the databases when the server was down. Shared scsi might be the easiest, but you'll have to buy some Y-terminated scsi cables so that the main machine won't reset the scsi bus on the backup machine when it (the main machine) goes down.

Re: Backup Server
On Sunday 28 December 2003 03:26 pm, Matt Juszczak wrote: I read somewhere about the AMANDA project. Is that any good for a situation like this? Well, Amanda is certainly good for the backup of the data. The main site's here: http://www.amanda.org/ and Curtis Preston put part of his O'Reilly book online: http://www.backupcentral.com/amanda.html But... Amanda would not be a great choice because it's really a backup system and you'd end up having to write scripts to restore from dump files created by Amanda to the backup server filesystem. If you're going to that trouble, it would be easier to use rsync. Again, I think shared scsi or fibre channel would be the way to go. I'm not sure how well FreeBSD supports shared scsi/fibre channel drive sharing ( I know it supports some fibre channel adapters), however. If it does work well, you could have a central RAID array running RAID 10 and have the master DB server run with the drive mounted. If the master had problems, the backup/secondary could take over. You would have one set of data to contend with, and consequently, synchronization would not be an issue. My only concern would be filesystem writes and soft depends in general. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]
Compaq DL380 ciss error with FreeBSD 5.1
