Resize a RAID 1 volume on OSX Snow Leopard - how? (Note: software raid)

- by Emmel

I've scoured the Internet in search of an answer to this question, and as usual with OSX-related topics, I often don't find any deep-dive technical explanations sufficient enough to feel confident doing dangerous things. Here is my question: I have a Mac Pro, running OSX 10.6.2. I have, as my main root/boot disk, a RAID 1 volume called "Mirror1". Mirror1 is comprised of two 1 TB disks. Mirror1, however, is fixed at 640 GB. That's because, I originally took a 640GB disk, bought a terabyte disk, mirrored it (using diskutil appleraid enable...), when it synced I removed the 640GB and replaced it with a second 1 TB disk, and synced again. Voila! A single 640 GB replaced by two 1 TB disks in a mirror.. Actually, no. There's still something missing from the equation: Mirror1 needs to be expanded from 640GB to 1 TB to match the partition sizes on each of those disks. How do I do this? Perhaps the diskutil output will help: -> diskutil list /dev/disk0 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk0 1: EFI 209.7 MB disk0s1 2: Apple_RAID 999.9 GB disk0s2 3: Apple_Boot Boot OSX 134.2 MB disk0s3 /dev/disk1 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *1.0 TB disk1 1: EFI 209.7 MB disk1s1 2: Apple_RAID 999.9 GB disk1s2 3: Apple_Boot Boot OSX 134.2 MB disk1s3 /dev/disk2 #: TYPE NAME SIZE IDENTIFIER 0: GUID_partition_scheme *640.1 GB disk2 1: EFI 209.7 MB disk2s1 2: Apple_HFS Mac Disk 2 536.7 GB disk2s2 3: Microsoft Basic Data BOOTCAMP 103.1 GB disk2s3 /dev/disk3 #: TYPE NAME SIZE IDENTIFIER 0: Apple_HFS Mirror1 *639.8 GB disk3 -> diskutil appleraid list AppleRAID sets (1 found) =============================================================================== Name: Macintosh HD Unique ID: 1953F864-B474-4EB6-8E69-41834EBD0247 Type: Mirror Status: Online Size: 639.8 GB (639791038464 Bytes) Rebuild: manual Device Node: disk3 ------------------------------------------------------------------------------- # Device Node UUID Status ------------------------------------------------------------------------------- 0 disk1s2 25109BAE-5697-40EA-B612-0217851444F7 Online 1 disk0s2 11B83AB0-8148-4DB6-8761-DEF08C855F8D Online =============================================================================== Thanks in advance.

Hard Drive upgrade advice for a Dell PowerEdge 1950

- by user8185

My setup is a Dell PowerEdge 1950 with 2x 140Gb Hard drives in a RAID 1 configuration. The OS is Windows 2003 Web Edition and disk is partitioned into to two, a 12Gb C: partition and the remainder is the D: drive. Both are very close to full capacity. Ideally I want to replace those drives with 2x 1Tb drives while retaining all data. First of all is this possible without rebuilding the server? If so, will I need any 3rd party software, Symantec Ghost, Partition Master for e.g., to do this? Any general advice as to how to go about doing this?

Linux data storage and partitioning

- by Rajeev

In the following output of df -h you can see that i have added a new hard drive(/dev/hdd1) and have mounted as /hdd1. My question is if I start dumping data to /opt will that data be mounted in /hdd1 or / My goal is to utilise the new hdd1 instead of old disk(/dev/sda3). How can this be done? Filesystem Size Used Avail Use% Mounted on /dev/sda3 442G 312G 12G 86% / tmpfs 1.9G 0 1.9G 0% /dev/shm /dev/sda1 194M 57M 128M 31% /boot /dev/sdb1 1.7T 201M 2.6T 1% /hdd1

Partition table correpted in windows 7 machine as simple dynamic partition

- by raki

I have Windows 7 installed in my system. When I originally partitioned it I made 3 partitions and 16 gb space as unallocated. Later I tried to create a partition using this free space using diskmanagement tool. It shows free space as unusabe space and the only one option available is to make it as a simple partition. Unfortunately I made it as simple partition and all my partitions converted to simple dynamic partition. Now after reboot the OS is not loading. I tried to reinstall the OS by formatting the C drive, but it doesn't work. Now I can't load the OS properly. How can I install Windows 7 on my system without losing my data on the other two drives?
