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 all, I am having a problem when I do a zfs promote or a zfs rollback, I get a "dataset is busy error" I am now doing a image update to see if there was an issue with the image I have. Has anyone idea as to how to fix this issue? Thanks, Greg -- This message posted from opensolaris.org

Hi I am trying to install Windows using HVM but I get an error message that is totally useless and I am unable to figure out what the problem is. I just pulled xen-unstable.hg because nothing else supports my CPU yet. So here is what I get when I simply try to create the domain: [2008-05-28 13:55:26 16515] DEBUG (__init_s:1072) XendDomainInfo.create([''vm'',

I apologize if this has been covered before. I have not seen a blow-by-blow installation guide for Ubuntu onto an iSCSI target. The install guides I have seen assume that you can make a target visible to all, which is a problem if you want multiple iSCSI installations on the same COMSTAR target. During install Ubuntu generates three random initiators and you have to deal with them to get things

Hi, WARNING: Long post ahead I have an issue when starting multipathd. The kernel complains about "blk_cloned_rq_check_limits: over max segments limit". The server in question is configured for KVM hosting. It boots via iBFT to an iSCSI volume. Target is COMSTAR and underlying that is a ZFS volume (100GB). The server also has two infiniband cards providing four (4) more paths over SRP

Hello all, I am running an OpenSolaris server running 06/09. I installed comstar and enabled it. I have an ESXi 4.0 server connecting to Comstar via iscsi on its own switch. (There are two esxi servers), both of which do this regardless of whether one is on or off. The error I see is on esxi "Lost connectivity to storage device naa.600144f030bc450000004a9806980003.

Hi, I have a zfs volume that''s exported via iscsi for my wife''s Mac to use for Time Machine. I''ve just built a new machine to house my "big" pool, and installed build 129 on it. I''d like to start using COMSTAR for exporting the iscsi targets, rather than the older iscsi infrastructure. I''ve seen quite a few tutorials on how to use

Hello list, I started playing aroud with Comstar in snv_134. In snv_116 version of ZFS, a new hidden property for the Comstar MetaData has been intoduced (stmf_sbd_lu). This makes it possible to migrate from legacy (iscsi target daemon) to Comstar without data loss, which is great. Before this property you always lost the first 64k of your zvol data where comstar wrote it''s metadata -

Hi, referring to thread: http://www.gossamer-threads.com/lists/xen/users/177385#177385. I have the same thing going on: hypervisors with E5620 Xeon CPUs and hypervisors with E5410 CPUs. Live migrations go wrong when domU''s are not created on the latter and move from the E5410 servers to more recent ones. The rationale being that these CPU''s have less or other capabilities

The earlier post with the Dtrace probes definition (sent on April 23) was only to solicit feedback from all prospective users of iSCSI DTrace probes. I will follow up shortly with an updated document requesting approval from the community. thanks Priya -------- Original Message -------- Subject: Dtrace provider for the COMSTAR iscsi Target Port Provider - Review Request Date: Thu, 23 Apr

Can anyone confirm my action plan is the proper way to do this? The reason I''m doing this is I want to create 2xraidz2 pools instead of expanding my current 2xraidz1 pool. So I''ll create a 1xraidz2 vdev, migrate my current 2xraidz1 pool over, destroy that pool and then add it as a 1xraidz2 vdev to the new pool. I''m running b130, sharing both with CIFS and ISCSI (not

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

Hi there, I have a 512MB USB thumbnail which I used syslinux to create a bootable USB disk. It works fine with my old laptop and a few other computers. However, on my Dell Latitude E5410, it doesn't really work; when the Dell laptop boots, I pressed F9 to see the boot devices list and the thumbnail is not on the list. Some hints please? x -- [?] Please notice that v9 at dr.com is no

I do not seem to be able to get any where with the power management functions. I have had a look at the xenpm Wiki page, but it hasn''t helped.

sbdadm can be used with a regular ZFS file or a ZFS block device. Is there an advatage to using a ZFS block device and exporting it to comstar via sbdadm as opposed to using a file and exporting it? (e.g. performance or manageability?) Also- let''s say you have a 5G block device called pool/test You can resize it by doing: zfs set volsize=10G pool/test However if the device was already

Hi all, Using "old" way of sharing volumes over iscsi in zfs (zfs set shareiscsi=on) i can see i/o stats per iscsi volume running a command iscsitadm show stats -I 1 volume. However i couldn''t find something similar in new framework,comstar. Probably i''m missing something, so if anyone has some tips please share it :) Thanks in advance, Bruno -------------- next part

Hi, Nexenta CP and NexentaStor has integrated COMSTAR with ZFS, which provides 2-3x performance gain over userland SCSI target daemon. I;ve blogged in more detail at http://www.gulecha.org/2009/03/03/nexenta-iscsi-with-comstarzfs-integration/ Cheers, Anil http://www.gulecha.org
