similar to: ZFS/iSCSI target integration

Hi, are there currently any plans to make an iSCSI target created by setting shareiscsi=on on a zvol bindable to a single interface (setting tpgt or acls)? I can cobble something together with ipfilter, but that doesn''t give me enough granularity to say something like: ''host a can see target 1, host c can see targets 2-9'', etc. Also, am I right in thinking without

Hi, I am posting my question to both storage-discuss and zfs-discuss as I am not quite sure what is causing the messages I am receiving. I have recently migrated my zfs volume from b104 to b134 and upgraded it from zfs version 14 to 22. It consist of two zvol''s ''vol01/zvol01'' and ''vol01/zvol02''. During zpool import I am getting a non-zero exit code,

Hello, I want to setup an opensolaris for centralized storage server, using ZFS as the underlying FS, on a RAID 10 SATA disks. I will export the storage blocks using ISCSI to RHEL 5 (less than 10 clients, and I will format the partition as EXT3) I want to ask... 1. Is this setup suitable for mission critical use now? 2. Can I use LVM with this setup? Currently we are using NFS as the

What does it mean for the reported value of a zvol volsize to be less than the product of used and compressratio? For example, # zfs get -p all home1/home1mm01 NAME PROPERTY VALUE SOURCE home1/home1mm01 type volume - home1/home1mm01 creation 1254440045 - home1/home1mm01 used 14902492672

Starting from this thread: http://www.opensolaris.org/jive/thread.jspa?messageID=118786&#118786 I would love to have the possibility to set an ISCSI alias when doing an shareiscsi=on on ZFS. This will greatly facilate to identify where an IQN is hosted. the ISCSI alias is defined in rfc 3721 e.g. http://www.apps.ietf.org/rfc/rfc3721.html#sec-2 and the CLI could be something like: zfs set

I''m not sure if this is a problem with the iscsitarget or zfs. I''d greatly appreciate it if it gets moved to the proper list. Well I''m just about out of ideas on what might be wrong.. Quick history: I installed OS 2008.05 when it was SNV_86 to try out ZFS with VMWare. Found out that multilun''s were being treated as multipaths so waited till SNV_94 came out to

I''m posting here as this seems to be a zfs issue. We also have an open ticket with Sun support and I''ve heard another large sun customer also is reporting this as an issue. Basic Problem: Create a zfs file system and set shareiscsi to on. On a vmware esx server discover that iscsi target. It shows up as 249 luns. When attempting to then add the storage esx server eventually

I''d love to be able to server zvols out as SCSI or FC targets. Are there any plans to add this to ZFS? That would be amazingly awesome. -brian -- "Perl can be fast and elegant as much as J2EE can be fast and elegant.

Hey all, I''m setting up a ZFS based fileserver to use both as a shared network drive and separately to have an iSCSI target to be used as the "Hard disk" of a windows based VM runninf on another machine. I''ve built the machine, installed the OS, created the RAIDZ pool and now have a couple of questions (I''m pretty much new to Solaris by the way but have been

Follow-up : happy end ... It took quite some thinkering but... i have my data back... I ended up starting without the troublesome zfs storage array, de-installed the iscsitartget software and re-installed it...just to have solaris boot without complaining about missing modules... That left me with a system that would boot as long as the storage was disconnected... Reconnecting it made the boot

Does opensolaris iSCSI target support SCSI-3 PGR reservation ? My goal is to use the iSCSI LUN created by [1] or [2] as a quorum device for a 3-node suncluster. [1] zfs set shareiscsi=on <storage-pool/zfs volume name> [2] iscsitadm create target ..... Thanks, -- leon This message posted from opensolaris.org

How can I set up a ZVOL that''s accessible by non-root users, too? The intent is to use sparse ZVOLs as raw disks in virtualization (reducing overhead compared to file-based virtual volumes). Thanks, -mg This message posted from opensolaris.org

The `lofiadm'' man page describes how to export a file as a block device and then use `mkfs -F pcfs'' to create a FAT filesystem on it. Can''t I do the same thing by first creating a zvol and then creating a FAT filesystem on it? Nothing I''ve tried seems to work. Isn''t the zvol just another block device? -- -Gary Mills- -Unix Group-

Hello, I was doing performance testing, validating zvol performance in particularly, and found that zvol write performance to be slow ~35-44MB/s at 1MB blocksize writes. I then tested the underlying zfs file system with the same test and got 121MB/s. Is there any way to fix this? I really would like to have compatible performance between the zfs filesystem and the zfs zvols. # first test is a

Team, **Please respond to me and my coworker listed in the Cc, since neither one of us are on this alias** QUICK PROBLEM DESCRIPTION: Cu created a dataset which contains all the zvols for a particular zone. The zone is then given access to all the zvols in the dataset using a match statement in the zoneconfig (see long problem description for details). After the initial boot of the zone

I''ve been seeing read and write performance pathologies with Linux ext3 over iSCSI to zvols, especially with small writes. Does running a journalled filesystem to a zvol turn the block storage into swiss cheese? I am considering serving ext3 journals (and possibly swap too) off a raw, hardware-mirrored device. Before I do (and I''ll write up any results) I''d like to know

I''ve upgraded my system from ufs to zfs (root pool). By default, it creates a zvol for dump and swap. It''s a 4GB Ultra-45 and every late night/morning I run a job which takes around 2GB of memory. With a zvol swap, the system becomes unusable and the Sun Ray client often goes into "26B". So I removed the zvol swap and now I have a standard swap partition. The

I have a customer who has implemented the following layout: As you can see, he has mostly raidz zvols but has one raidz2 in the same zpool. What are the implications here? Is this a bad thing to do? Please elaborate. Thanks, Scott Gaspard Scott.J.Gaspard at Sun.COM > NAME STATE READ WRITE CKSUM > > chipool1 ONLINE 0 0 0 > >

I have a 5-500GB disk Raid-Z pool that has been producing checksum errors right after upgrading SXCE to build 121. They seem to be randomly occurring on all 5 disks, so it doesn''t look like a disk failure situation. Repeatingly running a scrub on the pools randomly repairs between 20 and a few hundred checksum errors. Since I hadn''t physically touched the machine, it seems a

Hello zfs-discuss, What would you rather propose for ZFS+ORACLE - zvols or just files from the performance standpoint? -- Best regards, Robert mailto:rmilkowski at task.gda.pl http://milek.blogspot.com
