OK, I am new at this but managed to get my Fedora 15 LAMP installed, up and running. NOW I want to add a second hard drive to use as a back up for my server. I installed the second HD (both are SATA's) as a slave and it shows up in my BIOS. I have looked till I am blue in the face but have not found anything about this. So my questions are as follows: 1) What is the command line to detect what HD's are on my server? 2) How do I format the slave HD? 3) How do I copy files to the second HD for back up? I appreciate anyones help!!!!!
Code: fdisk -l Let's assume your new hard drive is named /dev/sdb. Run Code: fdisk /dev/sdb to format it. If you just want to create one partition on it (/dev/sdb1), this would look as follows: Code: server1:~# fdisk /dev/sdb The number of cylinders for this disk is set to 10443. There is nothing wrong with that, but this is larger than 1024, and could in certain setups cause problems with: 1) software that runs at boot time (e.g., old versions of LILO) 2) booting and partitioning software from other OSs (e.g., DOS FDISK, OS/2 FDISK) Command (m for help): [COLOR="Red"]<-- m[/COLOR] Command action a toggle a bootable flag b edit bsd disklabel c toggle the dos compatibility flag d delete a partition l list known partition types m print this menu n add a new partition o create a new empty DOS partition table p print the partition table q quit without saving changes s create a new empty Sun disklabel t change a partition's system id u change display/entry units v verify the partition table w write table to disk and exit x extra functionality (experts only) Command (m for help): [COLOR="Red"]<-- n[/COLOR] Command action e extended p primary partition (1-4) [COLOR="Red"]<-- p[/COLOR] Partition number (1-4): [COLOR="Red"]<-- 1[/COLOR] First cylinder (1-10443, default 1): [COLOR="Red"]<-- <ENTER>[/COLOR] Using default value 1 Last cylinder or +size or +sizeM or +sizeK (1-10443, default 10443): [COLOR="Red"]<-- <ENTER>[/COLOR] Command (m for help): [COLOR="Red"]<-- t[/COLOR] Selected partition 1 Hex code (type L to list codes): [COLOR="Red"]<-- L[/COLOR] 0 Empty 1e Hidden W95 FAT1 80 Old Minix be Solaris boot 1 FAT12 24 NEC DOS 81 Minix / old Lin bf Solaris 2 XENIX root 39 Plan 9 82 Linux swap / So c1 DRDOS/sec (FAT- 3 XENIX usr 3c PartitionMagic 83 Linux c4 DRDOS/sec (FAT- 4 FAT16 <32M 40 Venix 80286 84 OS/2 hidden C: c6 DRDOS/sec (FAT- 5 Extended 41 PPC PReP Boot 85 Linux extended c7 Syrinx 6 FAT16 42 SFS 86 NTFS volume set da Non-FS data 7 HPFS/NTFS 4d QNX4.x 87 NTFS volume set db CP/M / CTOS / . 8 AIX 4e QNX4.x 2nd part 88 Linux plaintext de Dell Utility 9 AIX bootable 4f QNX4.x 3rd part 8e Linux LVM df BootIt a OS/2 Boot Manag 50 OnTrack DM 93 Amoeba e1 DOS access b W95 FAT32 51 OnTrack DM6 Aux 94 Amoeba BBT e3 DOS R/O c W95 FAT32 (LBA) 52 CP/M 9f BSD/OS e4 SpeedStor e W95 FAT16 (LBA) 53 OnTrack DM6 Aux a0 IBM Thinkpad hi eb BeOS fs f W95 Ext'd (LBA) 54 OnTrackDM6 a5 FreeBSD ee EFI GPT 10 OPUS 55 EZ-Drive a6 OpenBSD ef EFI (FAT-12/16/ 11 Hidden FAT12 56 Golden Bow a7 NeXTSTEP f0 Linux/PA-RISC b 12 Compaq diagnost 5c Priam Edisk a8 Darwin UFS f1 SpeedStor 14 Hidden FAT16 <3 61 SpeedStor a9 NetBSD f4 SpeedStor 16 Hidden FAT16 63 GNU HURD or Sys ab Darwin boot f2 DOS secondary 17 Hidden HPFS/NTF 64 Novell Netware b7 BSDI fs fd Linux raid auto 18 AST SmartSleep 65 Novell Netware b8 BSDI swap fe LANstep 1b Hidden W95 FAT3 70 DiskSecure Mult bb Boot Wizard hid ff BBT 1c Hidden W95 FAT3 75 PC/IX Hex code (type L to list codes): [COLOR="Red"]<-- 83[/COLOR] Changed system type of partition 1 to 83 (Linux) Command (m for help): [COLOR="Red"]<-- w[/COLOR] The partition table has been altered! Calling ioctl() to re-read partition table. Syncing disks. Next you must create a filesystem on the new partition, e.g. ext4: Code: mkfs.ext4 /dev/sdb1 You must mount the partition to a directory - the directory must exist. For example, if you want to mount it to /backup, create that directory first: Code: mkdir /backup Then mount /dev/sdb1 to /backup: Code: mount /dev/sdb1 /backup Afterwards you can copy your backups to the /backup directory.
Thanks Falko; I got to the part where you said to create a filesystem on the new partition. When I try to do that I get the following message: "/dev/sdb1/ is apparently in use by the system; will not make a file system here." What do I need to do here?
Based on what I have found researching this issue it looks like my second hard drive has a RAID configuration in the MBR of the HD. I am too NEW at using LINUX commands/command lines. Apparently there is a way to delete this or stop the problem but I have NO way of knowing how or what to do. Anyone with any ideas? Thanks in advance
Apparently this guy has figured out what the problem was (exactly like mine) and fixed it but I can't make heads or tails of it. http://www.overclockers.com/forums/showthread.php?t=667317
