similar to: ZFS Storage Pool advice

This question is concerning ZFS. We have a Sun Fire V890 attached to a EMC disk array. Here''s are plan to incorporate ZFS: On our EMC storage array we will create 3 LUNS. Now how would ZFS be used for the best performance? What I''m trying to ask is if you have 3 LUNS and you want to create a ZFS storage pool, would it be better to have a storage pool per LUN or combine the 3

I''ve compiled the 3.0-devel version on SUSE Linux 9.3. The ony problem is the qla2300 driver, which will not start all correctly on boot. So i cannot see other partitions than sda. --------------------------------------------------------------------------------- QLogic Fibre Channel HBA Driver ACPI: PCI Interrupt 0000:04:02.0[A] -> GSI 24 (level, low) -> IRQ 185 qla2300

Hi to all in the list, we are trying to do some tests lab for a large scale mail system having this requirements: - Scale to maybe 1million users(Only for testing). - Server side filters. - User quotas. - High concurrency. - High performance and High Availability. We plan to test this using RHEL5 and maybe RHEL6. As a storage we are going to use an HP EVA 8400 FC(8 GB/s) We defined this

Hello, I''m thinking about a setup that looks like this: - 2 headnodes with FC connectivity (OpenSolaris) - 2 backend FC srtorages (Disk Shelves with RAID Controllers presenting a huge 15 TB RAID5) - 2 datacenters (distance 1 km with dark fibre) - one headnode and one storage in each data center (Sorry for this ascii art :) ( Data Center 1) <--1km--> (Data

Hi folks, The following are initial virtio-scsi + target vhost benchmark results using multiple target LUNs per vhost and multiple virtio PCI adapters to scale the total number of virtio-scsi LUNs into a single KVM guest. The test setup is currently using 4x SCSI LUNs per vhost WWPN, with 8x virtio PCI adapters for a total of 32x 500MB ramdisk LUNs into a single guest, along with each backend

Hi all, we have just bought a sun X2200M2 (4GB / 2 opteron 2214 / 2 disks 250GB SATA2, solaris 10 update 4) and a sun STK 2540 FC array (8 disks SAS 146 GB, 1 raid controller). The server is attached to the array with a single 4 Gb Fibre Channel link. I want to make a mirror using ZFS with this array. I have created 2 volumes on the array in RAID0 (stripe of 128 KB) presented to the host

Hi, I am a libvirt qe, I am testing the function about the new location of disk auth element (as sub-element of the source element) in Backing Chain Management. And I have a questions: When all the backing chain are iscsi network disk type(no matter if the authentication is exist), start the guest , it will only has the top level disk in xml and there are no other backingStore in it. The test

Hi, For backing chain that all images are iscsi network disk type , such as iscsi://ip/iqn../0(base image) <-iscsi://ip/iqn../1(active image). Currently, 'qemu-img info --backing-chain' command can display correct backing file info, but after starting guest with the active image in backing chain, it don't include the related <backingStore> element in dumpxml. So,

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

We are interested in using Nut on our Federa 6.0 servers. However, our UPS systems are sold under the name "Geek Squad" (sold through the Best Buy chain of department stores). I'm pretty certain Geek Squad does not manufacture these units and they just rebrand them. Does anyone know who makes these units or what they are compatible with in terms of driver level protocol? The ones we

We have a Sun v890, and I''m interested converting existing ZFS zpool from c#t#d# to MPxIO. % zpool status pool: data state: ONLINE status: ONLINE scrub: scrub completed with 0 errors on Sun Jul 15 10:58:33 2007 config: NAME STATE READ WRITE CKSUM data ONLINE 0 0 0 mirror ONLINE 0 0 0 c1t2d0

zfs receive should allow option to disable immediately mount of received filesystem. In case of original filesystem have changed mountpoints, it''s hard to make clone fs with send-receive, because received filesystem immediately try to mount to old mountpoint, that locked by sourcr fs. In case of different host mountpoint can be locked by unrelated filesystem. Can anybody recommend a

Hi all, Imagine the following situation, you have : - one ISCSI storage server providing : lun0 and lun1 - the lun0 and lun1 contains a standard installation of Fedora : VM1 and VM2 - the standards installations define two VG VolGroup00 ... We didn't define LogicalVolume on the node and we attached directly the iSCSI lun to the VM without making partition or LV in Ovirt. On the

Hi. I have a simple (I think) question My dataset have these variables: names(data) [1] "v1" "v2" "v3" "v4" "v5" "v6" "v7" "v8" "v9" "v10" "v11" "v12" "v13" "v14" "v15" "v16" "v17"

Hi gurus, I was playing with zfs in a V890 before it was installed for production. We reinstalled it for production, but the 4 disks We used to play with zfs have a non standard format (slices comes from s0 to s8 not s2 for backup s7 does not exists) We need to recover those 4 disks to be used by Solaris Volume Manager. I know this would be an easy question, but I was trying to fix it

Hi list, I've the strange problem, that after some time of inactivity a share is being disconnected. This leads to a red 'X' in the Workplace's list of connected drives. When opening a disconnected drive, the drive is being reconnected. BUT: This has a very fatal side-effect: When f.e. an MS-Access database is open and the user does not use this db, the share is also being

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

Hi, I recently compiled dovecot-2.1.1 on Solaris 10 with Sun Studio, but when I want to compile Sieve for this version (dovecot-2.1-pigeonhole-0.3.0) I get an error: "sieve.c", line 578: identifier redeclared: sieve_multiscript_run and I see that declaration in sieve.h is different from definition in sieve.c, so compilation process fails with SunStudio cc compiler.

Doug Post@CACI 10/15/97 04:12 PM I have been trying to find an answer to a problem with samba and canot get any information. I have tried the samba web pages and they have not helped. How do I get into a newsgroup or is there an email address I can send the question to. This will affect many possible sights that may use Samba in the future for NFS. Could you point me in the right direction
