Go to single user mode. do: fsck -p(shouldn't be needed, but just in case) mount -u / mount -a swapon -a run disklabel -e on the drive disklabel -e [-r] aacd0s1 Add the following line in the edit file it gives you. h: * * 4.2BSD 2048 16384 89 (I am not sure about that 89 for bps/cpg. Just use what it wants to) Write and quit the edit session. Then to an newfs on the /dev/aacds1h partition newfs -b 16384 -f 2048 -i 2048 /dev/raacd0s1h (You could just take the defaults for the newfs, but I like to specify block and frag the same as in the disklabel and the -i causes it to make more inodes which I seem to need on larger file systems) Add a mount point for it however you want, for example mkdir /work add a line to your /etc/fstab /dev/ad0s3h /work ufs rw 2 2 Substitute your own mount point if you created one with a different name. Type mount -aand voila, you have it. You might have to run an fsck on it. > > > Thanks, > Scott > > > > ___ > freebsd-questions@freebsd.org mailing list > http://lists.freebsd.org/mailman/listinfo/freebsd-questions > To unsubscribe, send any mail to "[EMAIL PROTECTED]" > ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"
Add partition to existing disk
I have an existing system which I cannot reinstall and sysinstall seems like too much of a wizard to use on a well running existing system. When I built the system 2 years ago I decided to leave about 25GB of unpartitioned space for future unknown projects, I now have a use for the space but I can't for the life of me figure out exactly what steps are needed to use the space. The system is configured as follows: Dell PE 2650 with 3x36GB drives in a Hardware RAID 5 on a PERC controller 4.11-STABLE And the currect disklabel is: #disklabel aacd0s1 # /dev/aacd0s1c: type: ESDI disk: aacd0s1 label: flags: bytes/sector: 512 sectors/track: 63 tracks/cylinder: 255 sectors/cylinder: 16065 cylinders: 8849 sectors/unit: 142175187 rpm: 3600 interleave: 1 trackskew: 0 cylinderskew: 0 headswitch: 0 # milliseconds track-to-track seek: 0 # milliseconds drivedata: 0 8 partitions: #size offsetfstype [fsize bsize bps/cpg] a: 409600004.2BSD 2048 1638490 # (Cyl.0 - 254*) b: 3072000 4096000 swap# (Cyl. 254*- 446*) c: 1421751870unused0 0# (Cyl.0 - 8849*) e: 12288000 71680004.2BSD 2048 1638489 # (Cyl. 446*- 1211*) f: 4096000 194560004.2BSD 2048 1638490 # (Cyl. 1211*- 1466*) g: 6144 235520004.2BSD 2048 1638489 # (Cyl. 1466*- 5290*) As you can see I have space available from 84992000 through 142175187. I have done similar things in Solaris and other OS's but I'm just not sure exactly what the FreeBSD steps are to utilize this space. Any pointers are appreciated.
