similar to: Snapshots and backing store

We have some HDS storage that isn''t supported by mpxio, so we have to use veritas dmp to get multipathing. Whats the recommended way to use DMP storage with ZFS. I want to use DMP but get at the multipathed virtual luns at as low a level as possible to avoid using vxvm as much as possible. I figure theres no point in having overhead from 2 volume manages if we can avoid it. Has anyone

Hi everyone! Is there any way to create snaphot for a single disk of a virtual machine. As I konw, "virsh snapshot-create-as domain_name snapshot_name --disk-only" traverses all block devices to create snapshot. However I don't want to create snapshot except for root partition. The version of qemu and libvirt I used is as follows: qemu-1.4.2 and libvrit-0.10.2

Does anybody knows if is there a certified procedure in to backup a RAC DB 10.2.0.3 based on OCFS2 , via split mirror or snaphots technology ? Using Linux LVM and OCFS2, does anybody knows if is possible to dinamically extend an OCFS filesystem, once the underlying LVM Volume has been extended ? Thanks in advance Riccardo Paganini

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

Thanks for you reply! Firstly, I'm very sorry I forgot introduce the scenarios in my experiments. Supposing a case, I have a virtual machine with two disks. One is mounted as a root partition and the other is data partition and the second disk is an iscsi lun, that is to say, not a local disk or image. Now the result wanted is that creating a snapshot for the root disk but not for the data

Hi, With dovecot 1.0.2, depending on the client I can only see inbox, or all the folders. I see all the folders with pine and balsa, but can see only the inbox with squirel mail and thunderbird. Any idea what's going on here ? Thanks. Yves. ---- Yves Dorfsman yves at zioup.com

Dear All, because the organization I work for has to enter the 21 century eventually, and encouraged by the the excellent wiki's available, I'm giving Xen a try. I' ve tested setting it all up but I have this question concerning making backups. i' ve noticed that virsh snaphot-create does not work, and googling this, I can find many posts describing making backups with rbackup,

Hello, I have a Centos 6.2 clsuter with a CLVM partition on which I have a GFS2 file system. The problem rises when I make a snapshot from my FC NetAPP FAS2020. After I make the snapshot (it is a rw snapshot) of my LUN, I am not able to mount it from any of my cluster nodes, because the Physical Volume is seen two times one time on the standard LVM partition and the other time on the snapshot

Hi all, I have a situation where I need to consolidate a few servers running Solaris 9 and 8. If the application doesn''t run natively on Solaris 10 or Nevada, I was thinking of using Solars 9 or 8 branded zones. My intent would be for the global zone to use ZFS boot/root; would I be correct in thinking that this will be OK for the branded zones? That is, they don''t care about

Is there any way to make the AuthorizedKeysCommand as the user which is trying to log in? Thanks. -- Yves.

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

Hi. We have a configuration and audit application called Tripwire Enterprise (7.5) that is running on a Red Enterprise Linux 5.2 server. On this server, we are using winbind (samba version 3.0.33) for authentication (against Windows AD). When we try to run a configuration check on users and permissions we get an error that there is a problematic frame : C [libnss_winbind.so.2+0x129f] . I

Hi, I'm trying to make samba working with Solaris ZFS Snaphots. Solaris 10 is running on a x64/X86 box which is both Samba (3.4.2) server and Zfs server. I created home/delaye filesystem with home zfs pool. # zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT home 1.98G 2.60M 1.98G 0% ONLINE - home/delaye 2.47M 1.95G 1.66M /home/delaye

We''re setting up ZFS in front of an MD3000i (and attached MD1000 expansion trays). The rule of thumb is to let ZFS manage all of the disks, so we wanted to expose each MD3000i spindle via a JBOD mode of some sort. Unfortunately, it doesn''t look like the MD3000i this (though this[1] post seems to reference an Enhanced JBOD mode....), so we decided to create a whole bunch of

I am wondering if any one knows of a way to manage Xyratex disk shelves from CentOS (in particular CentOS 4). More details: Some years ago I installed a NAS unit from Exanet which consists of 2 rebadged IBM x3650 head nodes and a couple of Xyratex disk shelves with a total of 96 TB of raw disk, connected by fibre channel. The operating system is based on CentOS 4.4, but is modified, and runs a

Please reply to david.curtis at sun.com ******** Background / configuration ************** zpool will not create a storage pool on fibre channel storage. I''m attached to an IBM SVC using the IBMsdd driver. I have no problem using SVM metadevices and UFS on these devices. List steps to reproduce the problem(if applicable): Build Solaris 10 Update 2 server Attach to an external

So I'm trying to RAID-1 this system which has two identical disks installed in it, and it isn't working for some reason. I started by doing a CentOS-4 install on /dev/sda1 as root, and with /dev/sda2 as my swap. I finish the install, yum update, and then I want to make the mirrors. I copy the partition table from one disk to the other: # sfdisk -d /dev/sda | sfdisk /dev/sdb I create
