Sender: owner-freebsd-questions@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.ORG I am so confused. The machine has 2 identical SCSI drives: size, manufacturer, what on them I'm not sure anymore. # df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/da0s1a 99183 27958 63291 31% / /dev/da0s1g 7203658 40912 6586454 1% /home /dev/da0s1f 992239 690397 222463 76% /usr /dev/da0s1e 127023 1804 115058 2% /var procfs 4 4 0 100% /proc I thought I was mounting the second drive by doing: # mount da1s1 /BU # cd /BU # ls -l drwxr-xr-x 15 root wheel 2048 May 4 13:16 etc drwxr-xr-x 5 root wheel 512 May 11 05:35 home BUT the second drive was once partitioned the same as the boot drive so the copied files are just going to "/" on the second drive in a small partition. #df Filesystem 1K-blocks Used Avail Capacity Mounted on /dev/da0s1a 99183 27958 63291 31% / /dev/da0s1g 7203658 40912 6586454 1% /home /dev/da0s1f 992239 690397 222463 76% /usr /dev/da0s1e 127023 1804 115058 2% /var procfs 4 4 0 100% /proc /dev/da1s1 99183 43280 47969 47% /BU See, it's half full and /BU is the same size as /. #Now it's start getting more interesting. So I thought, "how nice, I can mount all the partitions on da1 and copy the same file systems." Like: /dev/da1s1a /BU /dev/da1s1g /BUhome And so on. But there was no /dev/da1s1a. So being braver than smart, I don't read about MAKEDEV and do: # MAKEDEV da1s1a. I got lost but it appears to have made da1s1a - da1s1h? BUT then it got really scary. # mount /dev/da1s1a /BU # cd /BU # ls -l -rw-r--r-- 2 root wheel 658 Nov 20 07:03 .cshrc -rw-r--r-- 2 root wheel 251 Nov 20 07:03 .profile -r--r--r-- 1 root wheel 4735 Nov 20 07:03 COPYRIGHT drwxr-xr-x 2 root wheel 1024 Mar 12 10:51 bin drwxr-xr-x 3 root wheel 512 Mar 12 10:52 boot drwxr-xr-x 2 root wheel 512 Mar 12 10:48 cdrom lrwxr-xr-x 1 root wheel 11 Mar 12 10:52 compat -> /usr/compat drwxr-xr-x 3 root wheel 13824 Mar 12 15:57 dev drwxr-xr-x 2 root wheel 512 Mar 12 10:48 dist drwxr-xr-x 15 root wheel 2048 Mar 15 11:03 etc drwxr-xr-x 2 root wheel 512 Mar 12 10:48 home -r-xr-xr-x 1 root wheel 3258128 Nov 20 08:02 kernel -r-xr-xr-x 1 root wheel 3258128 Nov 20 08:02 kernel.GENERIC drwxr-xr-x 2 root wheel 512 Nov 20 06:56 mnt drwxr-xr-x 2 root wheel 2560 Mar 12 10:48 modules dr-xr-xr-x 2 root wheel 512 Nov 20 06:56 proc drwxr-xr-x 2 root wheel 512 Mar 12 10:48 root drwxr-xr-x 2 root wheel 2048 Mar 12 10:51 sbin drwxr-xr-x 4 root wheel 1024 Mar 12 10:48 stand lrwxrwxrwx 1 root wheel 11 Mar 12 10:49 sys -> usr/src/sys drwxrwxrwt 2 root wheel 512 Mar 15 11:04 tmp drwxr-xr-x 2 root wheel 512 Mar 12 10:48 usr drwxr-xr-x 2 root wheel 512 Mar 12 10:48 var What the hell is that. I almost did: # cd /BU # rm -R * Thinking I was looking at some old installation on the second disk. It's an illusion. It must be the way I did MAKEDEV right? da0s1a and da1s1a are the same thing??? If you're still with me. I think I need to reformat the second disk. But I'm not sure what's real and what's an illusion. Look at the line below labeled "disk:" after disklabel -r for both da0 and da1: ns1[/]# disklabel -r da0s1 # /dev/da0s1c: type: SCSI disk: da0s1 ns1[/]# disklabel -r da1s1 # /dev/da1s1c: type: SCSI disk: da0s1 Obviously I am clueless. I'll go google and man for few hours now. Please, if anyone can shed some light. To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
