Hello Experts, When I try to create SR with lvm over iSCSI, it always failed, I list my xe command and debug info: [root@xcp16 log]# xe sr-create host-uuid=a226200e-f7ff-4dee-b679-e5f114d1e465 content-type=user name-label=shared_disk_sr shared=true device-config:target=192.168.1.2 device-config:targetIQN=iqn.2013-07.example:shareddisk device-config:SCSIid=1IET_00010001 type=lvmoiscsi The SR is

i''ve installed XCP 1.5-beta. i''m a little confused as to what has happened. everything so far seems to work. however, i need more information on what was done to my hard disk during the installation and how was the file system set up. in particular, i was investigating how to create a new logical volume to place my ISO file to use as my ISO storage (SR). i notice (see below with

Hai, I use following steps for LV backup. * lvcreate -L 5G -s -n lv_snapshot /dev/VG_XenStorage-7b010600-3920-5526-b3ec-6f7b0f610f3c/VHD-a2db885c-9ad0-46c3-b2c3-a30cb71d83f8 lv_snapshot created* This command worked properly Then issue kpartx command kpartx -av

I'm pulling my hair out trying to setup a mirrored logical volume. lvconvert tells me I don't have enough free space, even though I have hundreds of gigabytes free on both physical volumes. Command: lvconvert -m1 /dev/vg1/iscsi_deeds_data Insufficient suitable allocatable extents for logical volume : 10240 more required Any ideas? Thanks!, Gordon Here's the output from the

Hmm, don't you just love changing terminology! I've been using HSM systems at work since '99. BTW, DMAPI is the Data Management API which was a common(ish) extension used by amongst others SGI and IBM. Back to lvmcache. It looks interesting. I'd earlier dismissed LVM since it is block orientated, not file orientated. Probably because my mental image is of files migrating to

ZFS also does some fun things here if you want to build an SSD & spinning disk array - http://zfsonlinux.org/ On 11 January 2017 at 11:56, J Martin Rushton < martinrushton56 at btinternet.com> wrote: > Hmm, don't you just love changing terminology!

But if not, the log should contain something useful. I like the hypothesis about mdadm metadata version 0.9, however that's still really common on RHEL and CentOS. It

Hello, Please excuse my complete xen ignorance but I am hoping someone will be able ot help me out here. I recently built my first Xen box using a 2, 1TB drives in a raid configuration, 2TB total. I installed Xen, I am able to access it via XenCenter. However, I am trying to use some of that 2TB as a local datastore but for the life of me I cannot get it mounted, I keep on getting this error:

I've had good results with using SSD as LVM cache for gluster bricks ( http://man7.org/linux/man-pages/man7/lvmcache.7.html). I still use XFS on bricks.

During Gluster Summit, we discussed gluster volumes as storage for VM images - feedback on the usecase and upcoming features that may benefit this usecase. Some of the points discussed * Need to ensure there are no issues when expanding a gluster volume when sharding is turned on. * Throttling feature for self-heal, rebalance process could be useful for this usecase * Erasure coded volumes with

HSM also stands for "Hardware security module" Maybe lvmcache would be interesting for you? HSM is more popularly known as "tiering".

Package: xcp-storage-managers Version: 0.1.1-3 Severity: normal XCP cannot use iscsi block devices. Fails with iscsiadm: No active sessions. I ran the following commands trying to diagnose the problem: First introducing a SR and then creating a PBD with the needed configuration for the iscsi block device. These steps work fine but when I tried to plug the PBD I got the error: root at

Hi, We are looking into replacing our current storage solution and are evaluating gluster for this purpose. Our current solution uses a SAN with two servers attached that serve samba and NFS 4. Clients connect to those servers using NFS or SMB. All users' home directories live on this server. I would like to have some insight in who else is using gluster for home directories for about 500

Hello List, Merry Christmas to all !! Basically I''m trying to boot a Windows 2008R2 DC HVM with 90GB static max memory and 32GB static min.

I have attached the HVM boot log of successful start. Many times the node hangs as soon as the
