Solaris 10 - File System Size / Layout

Hello, I�m very new to Solaris OS � UNIX world and have a question around the file system.
I have SUN System with a single 36GB of Hard Disk, and eventually I want to install Oracle 10g on it as a development server for myself.
My question is around the file system size and layout
I have installed Solaris 10 and accepted the default file system, which is as below:
Filesystem size used avail capacity Mounted on
/dev/dsk/c1t1d0s0 5.0G 3.4G 1.6G 69% /
/devices 0K 0K 0K 0% /devices
ctfs 0K 0K 0K 0% /system/contract
proc 0K 0K 0K 0% /proc
mnttab 0K 0K 0K 0% /etc/mnttab
swap 1.5G 1.1M 1.5G 1% /etc/svc/volatile
objfs 0K 0K 0K 0% /system/object
/platform/sun4u-us3/lib/libc_psr/libc_psr_hwcap1.so.1 5.0G 3.4G 1.6G 69% /platform/sun4u-us3/lib/libc_psr.so.1
/platform/sun4u-us3/lib/sparcv9/libc_psr/libc_psr_hwcap1.so.1 5.0G 3.4G 1.6G 69% /platform/sun4u-us3/lib/sparcv9/libc_psr.so.1
fd 0K 0K 0K 0% /dev/fd
swap 1.5G 136K 1.5G 1% /tmp
swap 1.5G 88K 1.5G 1% /var/run
/dev/dsk/c1t1d0s7 28G 28M 28G 1% /export/home
What I don�t understand is when I eventually install Oracle, where will the directory go for it?
The /home/export folder is aprrox: 28GB which is now taking up most of the space, and I understand that this is for users, therefore my question is:
1.Should I have allocated a more space to the root file system for oracle during the OS install?
2. If so what should I do? (its not a production system and I know it will have to go somewhere on the single drive, I�m happy to rebuild as I�m still learning the OS).
Any suggestions?

Thanks, I do have this but needed info on the file system layout... but I have the info now...
If you select the auto file system layout on Solaris 10 then it gives the remaining space to the home/export . I have since re-installed, customised the file system layout and have space for the database.

Expand file system size

Dears
Can we expand mounted file system+ size on solris 10 ???, knowing that I'm not using SVM
Thanks

And you're asking this question in the Solaris 9 forum?
The answer is yes in both cases, though. 'growfs' will expand a mounted UFS filesystem.
It doesn't help you create the space necessary to expand it, though. That can be very easy or very difficult depending on how your storage is allocated.

Setting the file system size for the emulator

Hi,
I am trying to set the file system size of the emulator so I can test what happens when the system is full and I try to write to the file system. I am using WTK 2.5.1 and I went into preferences -> storage and set Storage size to 10KB. But when I run the emulator and check the available size of the root directories using:
try {
         Enumeration roots = FileSystemRegistry.listRoots();
         while (roots.hasMoreElements()) {
            String dir = (String) roots.nextElement();
            FileConnection fc = (FileConnection) Connector.open( "file:///" + dir );
            System.out.println( "Available Size on " + dir + " : "+ fc.availableSize());
            fc.close();
      } catch ( IOException ex ) {
         ex.printStackTrace();
}I get the remaining size of my pc's hard drive, not what is remaining from the 10KB I set.
Can you tell me the correct way to do this? I don't want to fill up my pc's hard drive in order to test this!!

Has anyone got an answer to this?

kin dlyhelp me on this....
Thanks in advance,
Prathap

Sorry, can't be done.
If it was any other filesystem than root, you could do by using SVM.
But root filesystems can't be stripes or concats. Only simple mirrors.
So SVM isnt going to work.
If the spare space was after the partiton. You might have been able to do it by the "dirty" method of manually expanding the partition and using
growfs to expand it. You would have had to do it by netbooting or cd booting since growfs can't be used on the current root.
But in any case, you can't do that either since the space if before the partition not after it.
So, reinstalling is your only option..
Well, If you have a spare disk, you might be able to copy the filesystem over to a larger partition on the other disk, growfs it and boot off that instead.
You'd want to try it on a test systen first...

Solaris File System/Device Management Information

Hi All,
I a writing a paper about the Solaris operating system and require information about the file system and device management of Solaris 8.
File Management:
I am looking for information or links to sites that would help me find more information about the solaris file system architecture, how it uses drive space, and some of the features of the Solaris file system
Device Management:
I am also looking for information or website links that cover how Solaris talks to devices (overview) and other device management architecture information.
any help is appreciated!

Don't use cp because it converts soft links into hard files. Its even worse when you have cyclic soft links. Use tar or cpio and you should be ok.
i.e. If you have a soft link to a file of 10G, a cp will result in 20G.

Thanks in Advance for your help..

You must have a lot of small files on the file system.
There are couple of ways, the simplest is to increase the size of the filesystem.
Or if you can create a new filesystem, but increase the inode count so you can utilize the space and still have enough inodes. Check out the man page mkfs_ufs and the option nbpi=n

Setting file system size on install

Well im about to reinstall Solaris 10 (hate that i just complted the 100+ patches just yesterday) because apparently the file system slice / is too small by default (why?)
and im not sure where to make the currection because I actually thought I had done this. During the installation, I selected the drive and clicked Custom install... then on first slice selected Solaris and gave the full hard disk space to that slice... or like I said, so I thought.
null

There are two different levels of "partitioning" on x86 (if that's what you're using).
The installer needs a primary partition to place all of the Solaris stuff.
Then in that partition, it assembles slices for the other Solaris filesystems. There is a point in the installer where you can press F4 to customize the sizing of the solaris slices.
For home usage, I'll almost always build a machine with only root and swap (no /export/home, /var, or anything else). That way, no problems with space allocation.

Increase file system size

Hello,
I have solaris9 system where on disk c0t0d0, I have 7 partitions. The first partition shows file system mounted=yes with 10GB space. This file system is near full ( 95% used). I need to increase the size. How can I do that?
I have another partition that shows 30GB and file system mounted=no. Can I create a file system to use this 30 GB? Does it disturb existing file system?
Appreciate your help.

I agree with the guest poster a few posts up. This could be a unique opportunity to think about Bike Trials something that she would really love to do.
Instead of just looking at what's available, think first about what you really want - what would be Bike Trial Seller fulfilling and enjoyable. Is there anything creative she has always wanted to do?
If she loves being a nurse, look at other opportunities within this field that would not involve physical work.
If nursing is just a job, and Bike Store she doesn't enjoy it that much, then look at this as a pointer towards doing something different.
Start making Bike Shop brainstorming lists about all the jobs she would love to and could do - you will come up with something that she can feel excited about.

Required "/" (root) file system size on UNIX for Solution Manager.

Hello SAP Gurus,
   I am setting up SAP Solution Manager 3.2 on HP-UX. It is asking me about 350MB free sapce on "/" file system for Central Instance installation and about 120MB free sapce on "/" file system for Database Instance installation.
   I am installaing everything on to shared disk which mounted under /usr/sap. Why it needs free sapce in "/" file system. Is there any workaround to get rid of this requirement, as I have very less free sapce on "/" file system and I don't want to take the risks involved in increasing this size.
   Are there any SAP recommended sizes for "/" file system?
   I stuck in the middle of setting up SAP landscape on HP-UX (11.23). I searched through the Installation documents but I couldn't find any thing helpful in this regard. It is urgent requirement to set up this so please let me know any solution or workaround ASAP.
   Any help is greatly appriciated.
Thanks in advance.

Hi Vaibhav.
Normally "canonical path not available for (folder name)" means:
1. Wrong username/password. Please double check you credentials.
2. The resource cannot be linked from the portal server. Please be sure that you can connect to the next ports in windows server from the Unix Server:
a. NetBIOS Session Service TCP 139 This port is used to connect file shares for example.
b. TCP 445 The SMB (Server Message Block) protocol is used among other things for file sharing in Windows NT/2000/XP. In windows NT it ran on top of NetBT (NetBIOS over TCP/IP), which used the famous ports 137, 138 (UDP) and 139 (TCP). In Windows 2000/XP/2003, Microsoft added the possibility to run SMB directly over TCP/IP, without the extra layer of NetBT. For this they use TCP port 445.
I hope these things help somebody.

Protect Solaris file system

Can we protect the file system (folder level protection) in Solaris box using access manager?

If I install Solaris 10 on a x86 platform and add a bunch of drives to it to create a zpool (raidz), how do I protect my root filesystem?Solaris 10 doesn't yet support ZFS for a root filesystem, but it is working in some OpenSolaris distributions.
You could use Sun Volume Manager to create a mirror for your root filesystem.
The files in the ZFS file system are well protected, but what about my operating system files down in the root ufs filesystem? If the root filesystem gets corrupted, do I lose the zfs filesystem too?No. They're separate filesystems.
or can I independantly rebuild the root filesystem and just remount the zfs filesystem? Yes. (Actually, you can import the ZFS pool you created).
Should I install solaris 10 on a mirrored set of drives?If you have one, that would work as well.
Can the root filesystem be zfs too?Not currently in Solaris 10. The initial root support in OpenSolaris will require the root pool be only a single disk or mirrors. No striping, no raidz.

Solaris File System/ Virtual File system Documentation

can anybody help me in finding solaris virtual file system documentaion/books ?
thanks in advance,
-mayur

AFAIK, the VFS is not an official (and documented) interface
and may change from solaris release to solaris release
(perhaps even with a new kernel patch).
Other, you can probably get the Solaris 8 Foundation Source,
and use it as the definitive reference documentation ;-)

How do increase the file system size

Hi friends,
My newly installed solaris 10 system shows Filesysem full error.
By mistake space allocated for Root is very less and 98% of the space in Root is consumed.
Do i need to restructure entire filesystem or increase space in Root would be sufficient..?
Its 160 GB Harddisk on Intel Core 2 duo. What is the best allocation for the same.
I am very new to Solaris. Trying to learn how does Opensource OS works...
Pls help me
Regards
Bijoy

If you have more drive space you can mount more space and allocate it to a mount point--this may take care of your problem, but if you are out of space and you are not buying any more drives.... then it's time for the install disks to come back out and configure more appropriately to your use.
I have my work machine at home on a x64 AMD with 120 GB of drive. I gave 40 GB to Solaris just to be sure I could do basic installations and grow a little.
Once your allocation is full you have 2 options... buy more and mount it, or reinstall... you choose.
Well, there is a 3rd... you could unmount one of the other allocations and split it, then mount some of it back to your OS and some back to what it was before, but you are going to be plagued with this your entire lifetime of that install.

Determining file system size/free amount programatically

I have to write a system activity reporting program that will report how much space is assigned to each file system, and how much is in use.
I CAN'T shell a system command and parse the output. Because of security issues this program must either use defined API's, or potentially parse a kernel data structure. I realize the inherent un-portability of parsing kernel memory.
Any help would be appreciated,
Thanks
