Protect Solaris file system

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

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/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.

My question here is why /usr/lib/libc/libc_hwcap1.so.1 file system is having same size as that of / root filesystem? and what is the significance of /usr/lib/libc/libc_hwcap1.so.1 file system..
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

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 ;-)

Solaris file system performance

I run postmark on solaris and ext3 to compare their performance. I found the Solaris is three times slower than ext3. Is there anything wrong? I use "mount" to display all mount point and can see logging is open for the disk I'm testing. I tried closing the logging by "mount -o nologging" and the performance if even worse. So I think the logging is working. But why the performance is still so bad? My computer has 2G ram and the disk I'm using is SATA disk. I found the white paper from SUN says solaris is much faster than ext3 and they use postmark too. Is there any other parameter?

postmark is all about metadata operation performance. Which UFS has always been fairly bad at since solaris is paranoid about flushing metadata and syncing the disks religously to avoid filesystem corruption in case of sudden reboot.
Logging is not primarily a performance optimisation. Its primary function is to avoid having to fsck the disk after an unclean shutdown. So its not surprising that logging doesnt help postmark all that much.
You can try mounting the filesystem noatime which should help a bit.
You can also try ZFS inctead of UFS which supposedly has excellent postmark scores.
You should also be aware that postmark is a very contrived benchmark which only adequately represents the performance of a small subset of programs. Specifically those which manipulate large numbers of small files. Like a mail server.

File system for SAP ECC, EP , BI and CRM installation on Solaris/DB2

Hello,
We are going to implement SAP ECC 6.0 with EP 7, BI and CRM on Solaris operating system with IBM DB2 database.
All these applications are going to be installed on single server, as being a basis person, I know this is not all recommended.
But due to client's requirement and keeping cost factor in mind I need to install all these application on single box.
Now here I need your help. as I basis person, I know the required Solaris file system for SAP ECC 6.0 but not having any Idea about other application like EP/ CRM and BI .
If anyone able to help me with required Solaris file system. it will be great help.
Please let me know if there is any query.
Thanks.

> All these applications are going to be installed on single server, as being a basis person, I know this is not all recommended.

Why not using Solaris zones/container? This decreases the administrative amount tremendeously since you will deal as with "single machines" but they all run together on one box.
> Now here I need your help. as I basis person, I know the required Solaris file system for SAP ECC 6.0 but not having any Idea about other application like EP/ CRM and BI .
So you'd need to read the installation guides

File Systems are not shown in CCMS Monitoring

Hi Gurus,
We have installed all SAP components in Solaris 10 zones including Solution Manager.
Solaris File Systems are not shown in CCMS Monitoring under FileSystem. It looks like SAPOSCOL is not sending the OS data to CCMS. It does not show file systems in OS06 also.
The probles exists on Systems runnig in Solaris 10 zones only and NOT on systems running on individual Servers. [without Solaris zones]
Thanks,
Pj

Hi,
You need take some special considerations while installing SOLMAN on SOLARIS 10 zones. Check these notes
Note 870652 - Installation of SAP in a Solaris 10 zone
Note 724713 - parameter settings for Solaris 10
Hope this will solve your problem.

Accessing FAT and NTFS file systems in same machine

hi
i m new in solaris
is it possible to access my windows file system in solaris.
file systems are FAT and NTFS.
regards

You should be able to mount FAT filesystems as type pcfs.
Theres no native support for NTFS, but I seem to remember a project working on that.
So google for solaris NTFS will probably find it..

Zfs destroy DOES NOT CHECK NFS mount file-systems

I asked this question twitter once and the answer was a good one, but I did some checking today and was surprised!!
# zfs destroy mypool/home/andrew
The above command will destroy this file-system no questioned asked but if the file-system is mounted you will get back the Device busy and if you have snapshot then they will be protected as well
server# zfs destroy mypool/home/andrew
cannot unmount 'tank/home/andrew
server# zfs destroy dpool/staff/margaret
cannot destroy 'dpool/staff/margaret': filesystem has children
use '-r' to destroy the following datasets:
dpool/staff/margaret@Wed18
dpool/staff/margaret@Wed22
BUT?
server# zfs destroy dpool/staff/margaret@Wed18
server# zfs destroy dpool/staff/margaret@Wed22
NFSclient# cd /home/margaret
NFSlient# ls -l
drwx------+ 2 margaret staff 2 Aug 29 17:06 Mail
lrwxrwxrwx 1 margaret staff 4 Aug 29 17:06 mail -> Mail
drwx--x--x+ 2 margaret staff 2 Aug 29 17:06 public_www
server# zfs destroy dpool/staff/margaret
server#
GONE!!!
I will file a bug report to see what Oracle say!
Comments?
I think there should be a hold/protect of file-systems
# zfs hold dpool/staff/margaret
Andrew

The CR is already filed:
6947584 zfs destroy should be recoverable or prevented
The zfs.1m man page, which covers the mounted case and the ZFS admin guide are pretty clear
about the current zfs destroy behavior.
http://docs.oracle.com/cd/E23824_01/html/821-1448/gamnq.html#gammq
Caution - No confirmation prompt appears with the destroy subcommand. Use it with extreme caution.
zfs destroy [-rRf] filesystem|volume
Destroys the given dataset. By default, the command
unshares any file systems that are currently shared,
unmounts any file systems that are currently mounted,
and refuses to destroy a dataset that has active depen-
dents (children or clones).
I'm sorry that you were surprised.
Accidents happen too, like destroying the wrong file system, so always have good backups.
Thanks, Cindy

How so I protect my root file system? - x86 solaris 10 - zfs data pools

Hello all:
I'm new to ZFS and am trying to understand it better before I start building a new file server. I'm looking for a low cost file server for smaller projects I support and would like to use the ZFS capabilities. 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? 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? or can I independantly rebuild the root filesystem and just remount the zfs filesystem? Should I install solaris 10 on a mirrored set of drives? Can the root filesystem be zfs too? I'd like to be able to use a fairly simple PC to do this, perhaps one that doesn't have built in raid. I'm not looking for 10 terabytes of storage, maybe just four 500gb sata disks connected into a raidz zpool.
thanks,

Solaris 10 - After installation read only file system

Dear All,
I have installed the Solaris 10 on my x86 system with out any problem. The installation was completed successfully. I have followed the installation instructions that are mentioned in the following link.
http://docs.sun.com/app/docs/doc/817-0544/6mgbagb19?a=view
I am facing a different problem. I am not able to create even a single file / sub-directory on any of the existing directories. It always says READ ONLY file system can not create firl / directory.
Please help me how to resolve this issue.
Thanks in advance.

What do you get for 'svcs -xv' output?

Hi,
I read the Message 591 (Agu 2003) and the problem is quite the same. A brief description: I have aLaptop ASUS with HDD1 60GB and a USB storage HDD (in next HDD2) 100GB. I installed Solaris 10 x86 on HDD2 (partition c2t0d0s0). At the end of installation I removed the DVD and using BIOS features I switched the boot to HDD2. All ok; I received the SUN Blue Screen and I choose the active Solaris option; but at the beginning of the boot I received the following error message

Command for Unzipping a password protected zip file in Solaris

Hi,
I got a requirement where I need unzip a password protected zip file using java in Solaris.I tried with
unzip -P but it is not working in India and Australia (may be I need to download some patch). Can any one help me to find out the solution.
Thanks
Naresh

Hi peterchun,
Thanks for your reply.
I was trying with correct password only but my Solaris is not able to recognize unzip -P command. Can you please let me know whether I need to install any patch on Solaris (my Solaris version is 9) for this command.
Basic requirement: password protected zip files comes to our application and those need to be unzipped to one particular location. As we are using JAVA/J2EE in our application, Can you please suggest any UNIX command (with example) for this requirement will be great.
Thanks,
Naresh

Unbootable Solaris 10 x86 installed on ZFS root file system

Hi all,
I have unbootable Solaris 10 x86 installed on ZFS root file system. on an IDE HDD
The bios keep showing the msg
DISK BOOT FAILURE , PLEASE INSERT SYSTEM BOOT DISK
please note :
1- the HDD is connected properly and recognized by the system
2- GRUB don't show any messages
is there any guide to recover the system , or detail procedure to boot system again
Thanks,,,

It's not clear if this is a recently installed system that is refusing to boot OR if the system was working fine and crashed.
If it's the former, I would suggest you check the BIOS settings to make sure it's booting from the right hard disk. In any case, the Solaris 10 installation should have writting the GRUB stage1 and stage2 blocks to the beginning of the disk.
If the system crashed and is refusing to boot, you can try to boot from a Solaris 10 installation DVD. Choose the single user shell option and see if it can find your system. You should be able to use format/devfsadm/etc to do the actual troubleshooting. If your disk is still responding, try a `zpool import` to see if there is any data that ZFS can recognize (it usually has many backup uberblocks and disk labels scattered around the disk).
