XenDesktopMaster

Brilliant! works perfectly, thanks very much

Hi Adrian,

I did exactly what you mentioned in your post and everything was working fine then this morning i upgraded my XenServer from 5.6 to 5.6 FP1and now it shows disconnected that additional local storage.

how to reconnect it ?

Thanks

error message：
The SR operation cannot be performed because a device underlying the SR is in use by the host.
can i do？

Hi Mark,

this article could help .

what is the best option between 2) and 3). What’s the advantage of having an ext partition vs lvm?

Using the EXT partition is in my opinion the best way. There could be a little performance penalty when using EXT but you have the possibility to access the created vhd files directly via ssh or scp.

Works for me.
Thanks

works for me too, thanks very much.

Thanks a lot Master. This really was some great help. I’m pretty new to XenServer (I use 5.6) and since I’m originally a Citrix guy I’m not used to Linux/XenServer commands that much.

My additional disk is now added but the system reports only 58GB available since the disk was first used in a Windows system and not cleared before mounting. There is still some HPFS/NTFS data on there. Can I reformat the disk in order to make all 500.1GB available to the system ? See below:

Disk /dev/sda: 500.1 GB, 500107862016 bytes
255 heads, 63 sectors/track, 60801 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System
/dev/sda1 * 1 523 4194304 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 523 1045 4194304 83 Linux
/dev/sda3 1045 60801 479995393 8e Linux LVM

Disk /dev/sdb: 500.1 GB, 500107862016 bytes

Device Boot Start End Blocks Id System
/dev/sdb1 * 1 7650 61440595+ 7 HPFS/NTFS

Thanks, Henri

My excuses for my ignorence but by using Google I solved my issue. First destroyed the SR via “xe sr-destroy uuid=”, then reformatted the disk using fdisk/fsck and afterwards recreated the SR again.

Thanks in advance, Henri

Henri, you’re welcome!

Hi, I have a problem with a 6TB partition; fdisk says that it is too big bla bla use parted bla bla
clearly I cannot install parted (I think).
Should I proceed anyway?
Thanks,
Miguel

Hi Miguel,

Hello,

as mark wrote i am also getting the same error:
The SR operation cannot be performed because a device underlying the SR is in use by the host.

Google did not help, because youre allways directed to the citrix knowlege center. http://support.citrix.com/article/CTX122233 Anyway the solution there does not fit on this problem.

Do you have any idea?

Thanks Stefan

Excelente, realmente funciona!!!

Hello,

i have a XenServer 5.6.0 with 3 disks (1.=1TB 2.=2TB 3.=1TB). After a problem i have to reinstall Xenserver, on disk 2 and 3 i have different VM installed from the first xenserve installation, but after the second installation i can’t find this VM’s. with the command:

[root@xenjm by-id]# ls -l

i can see /dev/sdb and /dev/sdc but how can i access (mount / reconnect) this VM’s on this disks?

Sorry for my english, this is not my language. Thank you for your help.

Jean-Marie, this should help: http://support.citrix.com/article/CTX120962

Thanks for the walkthrough!

The process worked great… for the first disk added (dev/sdb).

I now have another new physical disk installed (/dev/sdc) that fdisk -l sees, but when I run xe host-list, the UUID of /dev/sdb is returned… How do I call up the UUID of newest install?

Please advise.

Thanks again

Jim, the UUID from xe-host list isn’t a reference to the disk but a reference to the UUID of your XenServer hosts. So the IDs should be the same and everything is just fine!
