Partitioning a disk in Solaris 10
Hi,
I am new with Solaris 10, and I want to create a partition on the disk, which it has already very important data that is being backuped. I have read the documentation from sun, and it seems that the best way is with the command format and then partition.
But I have seen that is possible to do it in the System Management Console .
What do you recommend me?
And after the partition, I have to mount the file systems, again, do I?
I would appreciate all the help.
Best regards,
Juan
I don't think you can create a Solaris partition with the format command from either DOS or Windows.
Here is how you create a Solaris partition, as far as I know anyway:
1. Use Ranish PM to create Solaris partition before hand so that the installation won't create x86boot.
2. Create some free space available, and then run the installation. The process will let you create the Solaris partition along with x86boot.
3. If you don't create some free space before hand, you will have to install Solaris on other existing partition, which means whatever current operating system of yours will be erased.

Fdisk and format show different cylinders can't use whole disk for solaris?
Solaris 10 5/09 s10x_u7wos_08 X86
Format did not show enough cylinders, so we can't use whole raid5 (4x 146GB) volume.
How can we fix it? We need the full raid5 volume for our solaris.

Hi Smart71,
I know it sounds complicated, but it really isn't.
You need to select the option to manually edit the disk label
when you install solaris.
Your problem is that you have assigned 73 GB for your / (root)
and 63 GB for your swap. That's not the problem that I see. The problem is that the Solaris partition (and therefore the Solaris VTOC label inside) is only for 136GB. But the actual underlying storage is 409GB. So the entire partition and the VTOC have to be rewritten.
You only have 2 options. Either re-install Solaris, of re-partition the disk.
If you don't have a spare disk to copy root to and you want to use
the whole disk, with just one / root partition, you will need to shrink /swap
create another slice to copy root to temporarily, and then re-partition your disk. Agreed reinstalling is easiest. But moving slices around will not let you change the VTOC size.
eg:
boot from CD into single user mode.
partition the disk so that eg:
swap is 3 GB. eg: ( from cylinder 1 to cylinder 400 )
partition 3 is 7 GB ( from cylinder 401 to cylinder 1318 )
( if 7 GB is enough to hold all your / data )
write the disk label out
newfs partition 3
mount / on /a
mount partition 3 on /mnt
Copy everything from /a to /mnt eg:
rsync -vaxH /a /mnt
or
find /a -xdev -print | cpio -pdam /mnt
umount /a and /mnt
re partition the disk so that / takes all the free space.If that were your goal, you wouldn't have to move anything. Just repartition and use 'growfs' on the root filesystem directly (while booted from CD).
eg ( starting at cylinder 1319 to cylinder 17816 )
write disk label out
newfs part 0 for /
mount / on /a and part 3 on /mnt
copy everything back from /mnt to /a
Check /a to make sure everything is there.
umount /a and /mnt
re partition the disk to make /swap 10 GB
( starting at cylinder 1 to cylinder 1318 )
write disk label out.
And that's it.
The disk you are working on is 17816 cylinders in size.
yet down the bottom you say that :
Total disk size is 53502 cylinders
That tells me there are 4 disks in the raid 5 set, and that
you have probably been presented with 3 x 136 GB disks.
That means that you should have 2 x 136 GB disks free.
Use one of these to copy your /root to. and then
re-partition your first disk and copy data back.
Or partition another disk correctly, write a boot block to it
Copy your root data to it, and boot from it.The entire disk is presented to the machine (as seen in the fdisk output), but the Solaris partition is only using the smaller portion of it. You can't create a second Solaris partition and use it at the same time, either. Only one Solaris partition can be used at a time.

ASM with Oracle10 cannot see disks on Solaris
Hi,
I just installed Oracle10g on Solaris-64 and first thing I tried was to create database using ASM. Seems, ASM cannot find any disks though all 6 of them are available. I tried different ways, but there is no result so far. Any idea what am I doing wrong?
-DmitriOoh, ooh. I did. :)
I had the same problem. Permissions and ownership were set correctly. The path to the disk was set. I could see and touch the disk as the oracle user. But, dbca saw nothing. Connecting to the adm instance and using the gui to create the diskgroup failed to see the disk. After MUCH searching on Oracles sites (otn & metalink) I found this note Create Partitions in Solaris and add them as disks in ASM 271621.1 metalink. It is not really clear way there needs to be 500 MB in slice 0 on a Solaris partition, I tried it at 10MB and found it worked with either slice 4 (the recommendation from the note) or slice 6 (the one that almost everyone working with Solaris [other than this notes author] uses). The size may be much smaller. Oracle must be doing something in slice 0, but I dont know what it is.
Anyway, after partitioning the disk and reserving 10MB in slice 0, the disk did show up in dbca. I am about to reinstall Oracle and try from the beginning.
My next challenge is how do I place the control files and online redo logs on a different diskgroup than the main database. I did not see a way in dbca to manage this.

I want to create a two partition disk. One partition for time machine, the other for Lightroom backup. Currently Time Machine is using the entire drive and it is doing the intial encryption and is about 29% complete after two days. I've decided that I want to turn encryption off and partition the disk. So I do I start over?
With the external drive attached, open Finder>Applications>Utilities>Disk Utility. Select the external drive from the list in the left side panel of the DU window. In the main window panel, click Partition in the buttons top center of that panel.
Select the number of partitions you want and adjust their sizes.
For the first partition, click to highlight the partition, then select the format, Mac OS Extended (Journaled) and then the partition table as GUID [both of those are the defaults]. Click Apply and it will ask to confirm and erase and format that partion...oh, give the partition a name, like Backup.
Then repeat those steps for the second partition..and remember to name it...something like Lightroom.
Close Disk Utilitty and you are ready to send TM to the one partition, and do your backup of Lightroom to the second partition. -
I can't delete partition in disk utility, it keeps telling me that "the changes are too small"
I previously split my disk into two different disks, however I want to combine them together again, yet i was unable to delete the second partition. I can't delete partition in disk utility, it keeps telling me that "the changes are too small"
Plz help!!!!!!Make at least two complete backups of all your data. Boot from another drive and partition this one as desired. Restore the data.

When I need to restore my Mac from a time machine backup and then partition my hard disk (the disk inside the computer not the time machine disk), Disk Utility always says "Incorrect Number of Extended Attributes". I then boot into Recovery HD and run disk repair. The result? "The volume Macintosh HD appears to be OK". So then I reboot into normal OS and try the partition again, still Incorrect number of extended attributes. I have even tried /sbin/fsck -fy in single-user mode but it still says the volume is ok. I have tried partition my disk in the recovery HD and it still fails.
Can anyone please help me solve this problem?Try something stronger, such as DiskWarrior or TechTool Pro.

Can't create a 3rd partition in Disk Utility
Long story short I have used Boot Camp to get Windows, so I have 2 partitions. But, I need to create another partition to install another copy of Windows on it, but Disk Utility has grayed out the '+' to allow me to create a new partition. All I can do is delete the 'BOOTCAMP' partition which I don't want to do. I tried another way by going into Boot Camp Assistant and installing Windows through there. I have a bootable USB drive and I know how to install it, all that's stopping me is the partition issue.
Any ideas?
If it helps, I'm using a Late 2013 MacBook Pro with a 15" Retina Display, 2.5 GHz, 512 GB SSD, 16 GB RAM and a NVIDIA GT 750 M.
Thank you for your helpGood thing to mention that, I forgot to do that.
Unfortunately it did not help.. The screen to remove the existing Boot Camp partition does not pop up, it just tries to create the new Boot Camp partition.
The partition I'm trying to create it 150GB. The 50GB mentioned above was on the stock Fujitsu 250GB disk.
Edit:
I'm actually trying to avoid using Boot Camp Assistant.. I became to dislike the utility due to problems creating a partition on my previous HD.
I would like to create a partition using Disk Utility and then install Windows 7 by selecting that DVD to boot from.
Thank you for the tip though, I'll post it there as well! -
Resized partition using Disk Utility and now Windows 7 will not boot
Hi,
Hopefully someone can help me!!
I had previously used Boot Camp to install Windows 7. However, I later realised I had not given myself anywhere near enough disk space as I started using Windows for things I hadn't originally planned on using it for.
Anyway, long story short, to solve the problem I uninstalled some applications on my Mac OSX and used Disk Utility to decrease the size of my Mac partition. My plan was then to reboot to Windows and use a Windows application to increase the size of the Windows partition. However - I coudln't even get that far.
Upon decreasing the size of my Mac partition (succesfully) I restarted my Mac in order to boot to Windows. However, I was greeted with a message along the lines of "unable to boot to Windows please insert boot disk and press any key" (I can't remember the exact message).
I was wondering if anyone knows of any way to restore my Windows partition, retaining all of my previously saved files on my Windows disk. It's probably a long shot, but the thought of losing everything I have been working on for the last few months is a sickening one.
What does give me a bit of hope is that, if I click Boot Camp it seems to recognise that Windows 7 is installed as the option that appears is to uninstall it.
Furthermore, if I view partitions in Disk Utility, a "DISK0S4" is listed. However, it's only at 20gb - if this WAS my BootCamp partition previously, it was originally at something around 60gb (I think - either way, definitely bigger than 20gb!).
On top of this, my current Macintosh HD parition is at 260gb and with the DISK0S4 partition at 20.21gb, there seems to be some space missing... I'm hoping this is the files I've been working on over the last few months!
Anyway, I've done some searching on the net and it *seems* that GPT fdisk *might* be my savour. I've downloaded it but have no idea how to use it and don't plan on playing about with it as I could no doubt do some real damage. If it is likely to solve my problem however, I'm certainly more than capable of being walked through what I need to do.
Please help!Hi Christopher,
I also have problems with Windows rebooting after partition resize trying to reduce Mac side and increase Windows side. I do not see the BootCamp partition labelled as such while running disk utility. The Windows partition shows up when I boot up while pressing the ALT key. However, when I try to run Windows, it says " error loading operatig system".
I also followed instruction and went through to run gdisk successfully. Results towards the end.
What can be done? Windows still does not boot and It shows ? Suspicious MBR at sector 0.

2. BCA has failed, or you may have a Fusion drive which is causing problems.
3. You have incorrect permissions on the disk.

It already is a single Mac OS Extended journaled volume. Right? Here is an image from Disk Utility:
Any ideas?Hey there!
It sounds like you are unable to install BootCamp due to an error that your some files cannot be moved, and to format your disk as a single volume, but you have confirmed that it already is. I would verify and repair your disk permissions with the following article next, if you have already restarted your computer and tried again:
Disk Utility 12.x: Repair disk permissions
http://support.apple.com/kb/ph5821
Choose Apple menu > Software Update to make sure you have the latest version of Mac OS X.Software updates sometimes change a file’s permissions to improve security, so updating your software can solve some permissions problems.
Open Disk Utility, in the Utilities folder in Launchpad.
Select the disk you want to check.You can verify or repair permissions only on a disk with Mac OS X v10.7 Lion installed.
Click First Aid.
Do one of the following:
Click Verify Disk Permissions to test permissions.
Click Repair Disk Permissions to test and repair permissions.
Disk Utility repairs the permissions for files installed by the Mac OS X Installer, Software Update, or an Apple software installer. It doesn’t repair permissions for your documents, your home folder, or third-party applications.
If that does not resolve the issue, I would next verify and repair the disk with this:

Thank you for using Apple Support Communities.
Take care,

Change partitions on disk with NTFS and Mac OS Extended
I have a 1.5TB external drive formatted with 3 equal size partitions: 1 NTFS and 2 Mac OS Extended formats, each one ~500GB. I'd like to remove the NTFS partition and use the whole drive for the 2 Mac partitions. Could I copy the NTFS data to one of the Mac partitions, then delete the NTFS partition, and then enlarge the two remaining partitions, of course without losing the information that's already on each of them? My system is OSX 10.7.5 -- Lion.

Probably maybe, with a fair wind & some luck…
It depends on a few factors, such as the order of the partitions on disk, how the disk was originally created, what partition scheme it uses (e.g. GUID, Master boot record…). It also depends on if all that data can be crammed into an existing partition.
I doubt you want to hear this, but it is the safest option… backup the data on every partition before you begin modifying the disk structure.
You have nothing to lose with solid backups on another disk, disconnect it to be extra cautious.
If this disk fails to repartition or you find that the 2 remaining partitions won't not expand to fill all the free space (it just happens sometimes) you can create a new partition table & start over.
Disk Utility may also complain when you try to resize or delete a partition - sometimes it waits until the last button is pressed to begin a task only to tell you something isn't possible!
I wouldn't attempt this 'copy, delete, resize' unless I could afford to lose all the data on this disk, it should work, but there is too much room for error. -
Where in a lion install disc made from the installer can I find a bootable file with disk utilities?
I downloaded lion a few hours ago and installed.
I have 4 large hardrives (1.5TB) arranged in 8 partitions to allow me to work on a varied group of projects. I have some projects that need to be worked on with software running under Tiger, some with software that runs under leopard, some with snow leopard, and now Lion. I own multiple copies of software and multiple user pack system install discs.
On a regular basis, I back up chunks of work on projects to external discs, and special backup areas on one of my drives. I don't like using time machine because I am running many operating environments on my mac pro and I don't ever want to be tied to one operating environment for important functionality, and I want to maximize the open space on my hard drives.
Several partitions involve large video files. I am working on them in various versions of final cut, premiere and imovie. Because I have to use the same software versions my different clients are running, I don't want to move all the files " up" to a modern version. It would be professional suicide to stop accommodating my various clients. I say this to try to head off being told to make my clients upgrade. There are too many different clients and they are not going to replace all their equipment.
On these volumes with video files, I often fill them up and copy off what I need to backup before I erase and do a clean install. I also run VM Fusion and windows XP. I absolutely do not want to have a Recovery HD partition left on the drive when I erase or influencing the other partions using different OS versions on that same drive.
Is there a bootable disc on the installer disk I just made? Can I use the disk utilities to do a low level erase on the lion volume that will remove the recovery partition?
Can I go back to booting from Snow Leopard and erasing the Recovery partition with the drive partition that way? Will the Snow Leopard utility take out the Lion HD recovery partition?
I am used to erasing my drives and rebuilding my machine and I believe it is the right way to use my multiple drives in my workflow. Now that I've got this invisible recovery partition, can you help me remove it and create a bootable disc that includes disk utilities?I assume the unix pdisk command will show you want is going on.
You may not have a big worry. There have always been a lot of hidden partitions. Disk Utility under 10.4.11 reports this drive has three (my now report four ) partitions, when pdisk reports that there are 15.
Macintosh-HD -> Applications -> Utilities -> Terminal
Press return when done typing sudo pdisk -l
-l include a lower case L
The sudo command will ask for your administration password. No characters will appear when typing your password. Press return when done typing. sudo stands for super user do. It's just like root. Be careful.
