Hi experts, I have few issues about ZFS and virtualization: [b]Virtualization and performance[/b] When filesystem traffic occurs on a zpool containing only spindles dedicated to this zpool i/o can be distributed evenly. When the zpool is located on a lun sliced from a raid group shared by multiple systems the capability of doing i/o from this zpool will be limited. Avoiding or limiting i/o to

Hello, There is a feature of zfs (autoexpand, or zpool online -e ) that it can consume the increased LUN immediately and increase the zpool size. That would be a very useful ( vital ) feature in enterprise environment. Though when I tried to use it, it did not work. LUN expanded and visible in format, but zpool did not increase. I found a bug SUNBUG:6430818 (Solaris Does Not Automatically

Hi, LUN is connected to solaris 10u9 from NETAP FAS2020a with ISCSI. I''m changing LUN size on netapp and solaris format see new value but zpool still have old value.

Hello, I know, that you had this discussion a view days ago but I''m in the installation phase of our new production servers and I intend to migrate the data from UFS volumes to ZFS volumes in near future. For doing this it must be ABSOLUTELY sure that I can resize the SAN LUNs because during the last 4 years I had to double the LUN size every year. I tried to resize a test volume

How much fun can you have with a simple thing like powerpath? Here''s the story: I have a (remote) system with access to a couple of EMC LUNs. Originally, I set it up with mpxio and created a simple zpool containing the two LUNs. It''s now been reconfigured to use powerpath instead of mpxio. My problem is that I can''t import the pool. I get: pool: ###### id:

Hi, I do have a disk array that is providing striped LUNs to my Solaris box. Hence I''d like to simply concat those LUNs without adding another layer of striping. Is this possibile with ZFS? As far as I understood, if I use zpool create myPool lun-1 lun-2 ... lun-n I will get a RAID0 striping where each data block is split across all "n" LUNs. If that''s

Hello, Experts. I''ve got a problem. I''m trying to expand my main zpool (rpool), but don''t know how to do that. (i''m 100% newbie in non-windows world) I use Osol under Vmware on Windows. I had a pretty small vhdd -> only 12gb. Yesterday i decided to expand my virtual drive to 20gb. (After several tries to upgrade the OS to a newest dev-releases and

Hi All, I''m new on ZFS, so I hope this isn''t too basic a question. I have a host where I setup ZFS. The Oracle DBAs did their thing and I know have a number of ZFS datasets with their respective clones and snapshots on serverA. I want to export some of the clones to serverB. Do I need to zone serverB to see the same LUNs as serverA? Or does it have to have preexisting,

We have a Mirror setup in ZFS that''s 73GB (two internal disks on a sun fire v440). We currently are going to attach this system to an Equallogic Box, and will attach an ISCSCI LUN from the Equallogic box to the v440 of about 200gb. The Equallogic Box is configured as a Hardware Raid 50 (two hot spares for redundancy). My question is what''s the best approach to moving the ZFS

I''m building a system with two Apple RAIDs attached. I have hardware RAID5 configured so no RAIDZ or RAIDZ2, just a basic zpool pointing at the four LUNs representing the four RAID controllers. For on-going maintenance, will a zpool scrub be of any benefit? From what I''ve read with this layer of abstration ZFS is only maintaining the metadata and not the actual data on the

I just got a call from another of our admins, as I am the resident ZFS expert, and they have opened a support case with Oracle, but I figured I''d ask here as well, as this forum often provides better, faster answers :-) We have a server (M4000) with 6 FC attached SE-3511 disk arrays (some behind a 6920 DSP engine). There are many LUNs, all about 500 GB and mirrored via ZFS. The LUNs

Hi All, Its been a while since I touched zfs. Is the below still the case with zfs and hardware raid array? Do we still need to provide two luns from the hardware raid then zfs mirror those two luns? http://www.opensolaris.org/os/community/zfs/faq/#hardwareraid Thanks, Shawn -- This message posted from opensolaris.org

Hello SUN gurus I do not know if this is supported, I have a created a zpool consisting of the SAN resources and created a zfs file system. Using third part software I have taken snapshots of all luns in the zfs pool. My question is in a recovery situation is there a way for me to mount the snapshots and import the pool while the original is still active. Right now all I am able to do is export

We''re planning to build a ZFS-based Solaris NFS fileserver environment with the backend storage being iSCSI-based, in part because of the possibilities for failover. In exploring things in our test environment, I have noticed that ''zpool import'' takes a fairly long time; about 35 to 45 seconds per pool. A pool import time this slow obviously has implications for how fast

Hi guys, I have a pool made with three luns striped. After some scsi retryable messages, happened during a storage activity, zpool status start to report one checksum error on one file only. The zpool scrub find it but don''t solve it, and when I try to read the file, I get an I/O error. Again, when I try to copy the file, I get only some bytes copied, and then stops, I mean this is

Hi all, Can anyone explain to me, or point me to any docs that explain how the following numbers map together? I have multiple LUNS exported to my HBA''s from multiple EMC arrays. zpool status, and /dev/dsk show device names like: c0t6006048000038794003753594D333837d0 ONLINE 0 0 0 c0t6006048000038794003753594D333838d0 ONLINE 0 0 0

I''m trying to get maybe 200 MB/sec over NFS for large movie files (need large capacity to hold all of them). Are there any rules of thumb on how much RAM is needed to handle this (probably RAIDZ for all the disks) with zfs, and how large a server should be used? The throughput required is not so large, so I am thinking an X4100 M2 or X4150 should be plenty. This message posted from

Hello, I recently installed SunOS 5.11 snv_91 onto a Ultra 60 UPA/PCI with OpenBoot 3.31 and two 300GB SCSI disks. The root file system is UFS on c0t0d0s0. Following the steps in ZFS Admin I have attempted to convert root to ZFS utilizing c0t1d0s0. However, upon "init 6" I am always presented with: Bad magic number in disk label can''t open disk label package My Steps: 1)
