Re: [zfs-discuss] Scripting zfs send / receive

Is that > correct? yes, zfs can boot of a mirror or single disk ( not raidz or above ), actually zfs root can only boot of a slice in the disk, you can make the whole disk into a slice as such. Reason being that zfs does not boot of EFI labelled disks only SMI currently, you can use zpool attach to add disk to setup as wel, if you want to convert to a mirror. i tend to suggest a mirror for reliability. Not overly clear to me what you want, you say the 4 drives are going to be turned into the main file system, so is this what you will be using for root ( ie booting ) or are there other disks you will be using to boot. Also what solaris release is this ie zfs root will be in s10 update 6,or is in current nevada builds. Enda > > In this case, what needs to be out of the array?

Re: [zfs-discuss] mirroring zfs slice
Hi Use zpool attach from http://docs.sun.com/app/docs/doc/819-2240/zpool-1m zpool attach [-f] pool device new_device Attaches new_device to an existing zpool device. The existing device cannot be part of a raidz configuration. If device is not currently part of a mirrored configuration, device automatically transforms into a two-way mirror of device and new_device. If device is part of a two-way mirror, attaching new_device creates a three-way mirror, and so on. In either case, new_device begins to resilver immediately.

Where might I find it. it's the kernel patch, depending on how far back you are in the update's you might have to install m ultiple Kernel Patches. the latest one is 127127-11/127128-11 ( the u5 KU ) it depends on 120011-14/120012-14 ( the u4 kernel ) which depends on 118833-36/118855-36 the U3 kernel Above showing sparc/x86 versions You can get them from sunsolve.sun.com http://sunsolve.sun.com/show.do?target=patchpage Not sure about entitlement though, you will have to register at minimum ( no a/c needed as far as I know ), but you might need an a/c for certain patches. Also make sure you have latest patch utils patch applied as well ( 119254/119255 :- sparc/86 ), also run patchadd -a , the -a does a dryrun, and doesn't update the system, examine output, and then drop the -a if all looks ok. The recommended cluster ( under downloads in patch page ) has all the latest patches and requirements, might be easier to grab and work with it.

metalink doc 403202.1 appears to support this config, but to me reads a
little unclear.
{
Applies to:
Oracle Server - Enterprise Edition - Version: 9.2.0.5 to 10.2.0.3
Solaris Operating System (SPARC 64-bit)
Goal
Is the Zeta File System (ZFS) of Solaris 10 certified/supported by
ORACLE for:
- Database
- RAC
Solution
Oracle certifies and support the RDBMS on the whole OS for non-RAC
installations. However if there is an exception, this should appear on
the Release Notes, or in the OS Oracle specific documentation manual.
As you are not specific to cluster file systems for RAC installations,
usually there is no problem on install Oracle on the file systems
provided by OS vendor.But if any underlying OS error is found then it
should be handled by the OS vendor.
Over the past few years Oracle has worked with all the leading system
and storage vendors to validate their specialized storage products,
under the Oracle Storage Compatibility Program (OSCP), to ensure these
products were compatible for use with the Oracle database. Under the
OSCP, Oracle and its partners worked together to validate specialized
storage technology including NFS file servers, remote mirroring, and
snapshot products.
At this time Oracle believes that these three specialized storage
technologies are well understood by the customers, are very mature, and
the Oracle technology requirements are well know. As of January, 2007,
Oracle will no longer validate these products.
On a related note, many Oracle customers have embraced the concept of
the resilient low-cost storage grid defined by Oracle's Resilient
Low-Cost Storage Initiative (leveraging the Oracle Database 10g
Automatic Storage Management (ASM) feature to make low-cost, modular
storage arrays resilient), and many storage vendors continue to
introduce new, low-cost, modular arrays for an Oracle storage grid
environment. As of January, 2007, the Resilient Low-Cost Storage
Initiative is discontinued.
For more information on the same please refer to Oracle Storage Program
Change Notice

However it seems like the problem is not solved by IDR :( Hi Robert So this IDR has two bugs as fixed 6458218 assertion failed: ss == NULL 6495013 Loops and recursion in metaslab_ff_alloc can kill performance, even on a pool with lots of free data I have add'ed the IDR's requestors as they can comment, which one of the above fixes was not solved via this IDR in your testing.
