ZFS in Solaris 10

Hi all,
Two month ago, I have download Solaris 10, and there aren't the ZFS filesystem, so I want to know if Solaris have been upgraded and if it now contains the ZFS filesystem.
Thanks.

There are no Solaris 10 update releases at this time.
There are newer Solaris Express releases, but they don't include
ZFS.

Mounting zfs in Solaris 10

Currently I have three hard drives with:
Disk1: Solaris 10
Disk2: SXDE
Disk3: OpenSolaris (ZFS)
What is the proper way to mount Disk3 from Solaris 10 or SXDE

Hi
I think that the command that you need is 'zpool import' (on its own it will list pools that are available to import).
You may have problems if the version of ZFS on disk 3 is higher than the drivers on either Solaris 10 or SXDE (I recently tried importing an SXCE created ZFS partition into FreeBSD 7, but it failed for this reason).

Zfs on solaris 10 and home directory creation

I am using samba and a root preexec script to automatically create individual ZFS filesystem home directories with quotas on a Solaris 10 server that is a member of a Windows 2003 domain.
There are about 60,000 users in Active Directory.
My question is about best practice.
I am worried about the overhead of having 60,000 ZFS filesytems to mount and run on Solaris 10 ?

Testing results as follows -
Solaris 10 10/09 running as VM on Vmware ESX server with 7 GB RAM 1 CPU 64 bit.
ZFS pool created with three 50 GB FC LUNS from our SAN (Hardware RAID5). There are shared to ESX server and presented to the Solaris VM as Raw Device Mappings (no VMFS).
I set up a simple script to create 3000 ZFS filesystem home directories
#!/usr/bin/bash
for i in {1..3000}
do
zfs create tank/users/test$i
echo "$i created"
done
The first 1000 created very quickly.
By the time I reached about 2000 each filesystem was taking almost 5 seconds to create. Way too long. I gave up after about 2500.
So I rebooted.
The 2500 ZFS filesystems mounted in about 4 seconds, so no problem there.
The problem I have is why do the ZFS file system creation time drop of and become unworkable? I tried again to add to the pool after reboot and there was the same slow creation time.
Am I better off with just one ZFS file system with 60,000 userquotas applied and lots of ordinary user home directories created under that with mkdir?

Boot from second hard drive with ZFS in Solaris 10 x86

Hi,
The usual menu.lst to boot Solaris10 x86 with a boot environment that contains a ZFS boot loader is this one
title Solaris 10 5/08 s10x_nbu6wos_nightly X86
findroot (pool_rpool,0,a)
kernel$ /platform/i86pc/multiboot -B $ZFS-BOOTFS
module /platform/i86pc/boot_archive
title Solaris failsafe
findroot (pool_rpool,0,a)
kernel /boot/multiboot kernel/unix -s    -B console=ttyb
module /boot/x86.miniroot-safeI understand that to add an alternate boot disk, I have to play with installgrub and then attach it in the pool.
But my question is : Is there a way to boot from my alternate hard disk by adding a new entry in menu.lst or is the only
way is to modify the BIOS parameter?
Thanks for your help,

But ok, I imagineI can add a grub entry. But what I want to know is what is the exact way to boot from an alternate hard disk on Solaris 10u6
x86.AFAIK there are only two ways to do this. Select the disks via BIOS which becomes a royal PITA in a short amount of time or play with a boot manager such as GRUB until you get the syntax right.
Personally I put all OS's on the primary disks if possible to avoid these situations and if I have others to play with then you can easily mount them in or set them up as D: drive etc...
The only exception would be in an enterprise setting where you need to do things such as mirroring but then again in those situations it's only one OS per machine anyways so it's much easier.
So at the end, I am not sure what I have to configure and what is the procedure to boot from my alternate boot diskTry the grub homepage for the grub manual and hopefully for a mailing list or try a search engine.
http://docs.sun.com/app/docs/doc/819-5461/zfsboot-1?a=view
has an example to follow of using -B.
And moreover, the installgrub does not working for me :

You shouldn't need to do an installgrub if you installed Solaris. Try c5t4d0s0 not s2.

How to convert ufs to zfs in Solaris 10

After installinng solaris 10 i wnat to convert my ufs to zfs , how can i do that , unfortunately tehre is no documentation available in docs.sun.com. any help is greatly appreciated

I found a document on Sun site long time ago titled "The best file system in the world" (Peter Baer Galvin's as far as I remember). I believe it can be still found somewhere there, and here are some of citations that may be helpful:
There are many things that ZFS is, currently, and a few that it is not. The most frustrating current limit is that ZFS cannot be the root file system. A project is underway to resolve that issue, however. It certainly would be nice to install a system with ZFS as the root file system and then to have features like snapshots available for systems work. Consider taking a snapshot, making a change that causes a problem on the system (e.g., installing a bad patch), and then reverting the system to its pre-patch state by restoring the snapshot.
Also, ZFS can be imported and exported, but it is not a true "clustered file system" in that only one host can access the file system at one time.
An open issue is the support of ISVs, such as Oracle, for the use of a ZFS file system to store their data. I'm sure this will come over time.
Hot spares are not implemented currently. If a disk fails, a zpool replace command must be executed for the bad disk to be replaced by a good one.
A mirror can be removed from a mirror pair by the zpool detach command, but RAID-Z sets and non-mirrored disks currently cannot be removed from a pool.
Also, currently there is no built-in encryption, and at this point ZFS is a Solaris-only feature. Whether ports will be done to other operating systems remains to be seen.
Just a brief word on the readiness of ZFS for production use. Usually, a new file system would not even be considered for production use for quite a while after its first ship. ZFS, on the other hand, may well garner production use immediately on its production ship. The testing that has gone into ZFS is astounding, and in fact testing was considered a first-class component of the ZFS design and implementation.

How to config ZFS in solaris 10

hi,
I'm testing solaris 10 x86 edition in my PC. but i don't
find any information about how to config ZFS in 10 (X86).. ;-(
if anybody know it, pls.give me some information.
thanks a lot.

ZFS has not yet been integrated into Solaris 10...
At this time you need either the "Software Express for Solaris 2/06"
( http://www.sun.com/software/solaris/solaris-express/ ) or the
"Solaris Express: Community Release"
( http://www.opensolaris.org/os/downloads/on/ ) to play with ZFS.

ZFS in solaris 10 x86 ?

In the Solaris 10 installation, I can only set the filesystem to UFS ? I want to know if ZFS is in Solaris 10 for X86 and if yes, how I can enable it.
Thanks.
Willits

I'm afraid ZFS didn't make it in time for the first official
Solaris 10 release ('GA') for either sparc or x86.
Promised for an early update release.
BTW, does anyone know what GA stands for?

Can't boot with zfs root - Solaris 10 u6

Having installed Solaris 10 u6 on one disk with native ufs and made this work by adding the the following entries
/etc/driver_aliases
glm pci1000,f
/etc/path_to_inst
<lang pci string for my scsi controller> glm
which are needed since the driver selected by default are the ncsr scsi controller driver that do not work in 64 bit.
Now I would like to create a new boot env. on a second disk on the same scsi controller, but use zfs instead.
Using Live Upgrade to create a new boot env on the second disk with zfs as file system worked fine.
But when trying to boot of it I get the following error
spa_import_rootpool: error 22
panic[cpu0]/thread=fffffffffbc26ba0: cannot mount root path /pci@0,0-pci1002,4384@14,4/pci1000@1000@5/sd@1,0:a
Well that's the same error I got with ufs before making the above mentioned changes /etc/driver_aliases and path_to_install
But that seems not to be enough when using zfs.
What am I missing ??

Hmm I dropped the live upgrade from ufs to zfs because I was not 100% sure it worked.
Then I did a reinstall selecting to use zfs during the install and made the changes to driver_aliases and path_to_inst before the 1'st reboot.
The system came up fine on the 1'st reboot and did use the glm scsi driver and running in 64bit.
But that was it. When the system then was rebooted (where it made a new boot-archive) it stopped working. Same error as before.
I have managed to get it to boot in 32bit mode but still the same error (thats independent of what scsi driver used.)
In all cases it does pop the SunOS Relase banner and it do load the driver (ncrs or glm) and detects the disks in the correct path and numbering.
But it fails to load the file system.
So basically the current status are no-go if you need to use the ncrs/glm scsi driver to access the disks with your zfs root pool.
File-Safe works and can mount the zfs root pool, but that's no fun as server OS :(

ORACLE ASM OR ZFS IN SOLARIS 11

ORACLE DBA EXPERTS
What kind of storage technology is recommended in order to implement an Oracle 11gr2 database in a Solaris 11 OS?
-Oracle ASM or the Solaris 11 ZFS filesystem.
Its any difference between the performance of both storage technologies?
Thanks for answer my questions and i wish to yours a very "Happy Hollydays".
Sincerely,
JOHN JAIRO GOMEZ LAVERDE

From what I understand Oracle recommends ASM. You cannot directly compare ASM with ZFS. ASM is a storage solution providing data management, availability and redundancy specific to Oracle. ZFS is an advanced file system. Whether you choose one over the other will depend on your storage requirements and knowledge.

Resize the zfs on solaris 5.10

hi All,
i have solaris 5.10 serving zfs filesystem via equallogic iscsi , i have resized the luns from the equallogic gui but i do not know how to resize at the solaris server. what are the steps? can i do it while filesystem online?

thanks guys for your replies, here is the output of the command " zpool status -v"
can someone give me a step by step on how to resize, also, can i do the resize while the filesystems online.? anything else i need to worry about doing this resize process?

SAP R/3 on Oracle / Solaris / ZFS

Hello,
My unix administator is planning on upgrading to a new OS environment to Solaris 10 with ZFS. We currently run SAP R/3 4.6C kernel / Oracle 9i on Solaris release 5.8 and I would like to know what would be the path to take from here. Does SAP R/3 4.6C or even 4.7 Support ZFS and what about Running Oracle 10g datafiles on a ZFS system for the SAP Database.
Any support is appreciated,
Arun

Oracle doesn't certify any more filesystems or certain Storage Systems (see Oracle Metalink 403202.1 - Zeta File System (Zfs) On Solaris 10 Certified/Supported By Oracle) but it's supported to run on them
We run several databases (Oracle and non-Oracle) on ZFS - and combined with zones it's GREAT to consolidate systems.
Check http://www.sun.com/software/whitepapers/solaris10/zfs_veritas.pdf for a comparison between VXFS and ZFS.
The SAP system itself is agnostic about the underlying filesystem.

How to determine the file system on Solaris

Friends,
How to determine which file system I have installed UFS or ZFS on Solaris
Thanks

Other methods would include looking at the /etc/vfstab if it's in there or fstyp(1M):

Is there a way to undelete files in solaris, either solaris 8 or solaris 10

Hi Everyone,
Want to check with you whether any option available to undelete a file in solaris8 or solaris10. Please let me know.
Thanks everyone,
Lakshmana Immidi.

Maybe, but mostly no. If you do a Google search you will see many ways to undelete files, but all are based on a number of assumptions:
1. You are not using ZFS. Most of these methods work with UFS or ext2/ext3.
2. You stop immediately upon accidentally deleting the file. A multiuser system is continually generating files, whether from users or from temporary processes that are running all the time. Any disk blocks your original file was on may get over-written very quickly by new files. Inodes of the files may get re-used, and inodes don't contain the name of the file they reference.
If using ZFS on Solaris 10, using snapshots is the best way to preserve user files. You can roll back to a previous snapshot, or even just go to the directory the snapshot is stored in and copy the file over. You can set up a script to take snapshots at various times to ensure you always have a fairly recent copy. You can also take incremental snapshots so you don't have to copy tons of data with each snapshot.

Using ZFS for Oracle RAC 11gR2 binaries

Hi,
We have following scenario,
Two Node Cluster: Oracle RAC 11Gr2 with Clusterware on Solaris 10
We want to keep Oracle & Clusterware binaries on ZFS mirror file system on each node locally and for Data files, FRA, Voting disks & OCR on shared SAN using ASM.
My question, is the above scenario certified by Oracle or can we keep Oracle binaries on ZFS...?
Will appreciate your input.
Thanks

Well my confusion started after reading this doc on oracle support:
Certification of Zeta File System (Zfs) On Solaris 10 for Oracle RDBMS [ID 403202.1]
"Oracle database 10gR2 (10.2.0.3 and higher patches), 11gR1 (11.1.0.6 and higher patches) and 11gR2 (11.2.0.1 and higher patches) are certified with Solaris 10 ZFS on Sparc 64-bit and Solaris x84-64. See Solaris ZFS_Best_Practices_Guide. This is for single instance ONLY. ZFS is currently not applicable to RAC and not Certified to use it as a shared filesystem."

ZFS compression(lzjb) on Oracle Database Files

Hi all,
We have just run few tests with Oracle Database files and using the lzjb compression on zfs with Solaris 10 would bring great space savings. Im looking at 2-3x fold compression ratios on Oracle files. Now, I am aware of slight CPU utilisation (2-3%) on our case, which is nothing compared to benefits.
Raises a few questions tough, are the any cave eats to know about? Why should I NOT turn compression on for Oracle files? From the Oracle Whitepaper I gather that compression is suggested turned on for Archives, but no mention for others.
http://www.oracle.com/technetwork/server-storage/solaris/config-solaris-zfs-wp-167894.pdf
Any suggestions and experiences are welcome

All you need to do is install windows and then oracle 10g.
after the complete installation,shutdown the database.
Now overwrite your previous datafiles including control files and you are done.
