How to Create ISO Storage on XenServer
Published: 30 Apr 2013
This post walks you through how to create local volume on a XenServer host to serve as ISO repo.
1. ssh to the XenServer host
2. Check free local disk space: df -h
Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda1 4127440 1976852 1940924 51% /
none 381120 4 381116 1% /dev/shm
/opt/xensource/packages/iso/XenCenter.iso
52408 52408 0 100% /var/xen/xc-install
3. Check available physical disk space
$ pvs
PV VG Fmt Attr PSize PFree
/dev/sda3 VG_XenStorage-43851e54-d3bf-0602-5e84-93629cfe7851 lvm2 a- 457.75G 457.75G
4. Check volume groups
$ vgs
VG #PV #LV #SN Attr VSize VFree
VG_XenStorage-43851e54-d3bf-0602-5e84-93629cfe7851 1 1 0 wz--n- 457.75G 457.75G
5. Create the new LV (Logical Volume) in the available VG
lvcreate -L 10G -n iso-images VG_XenStorage-43851e54-d3bf-0602-5e84-93629cfe7851
6. list
lvscan
7. make a filesystem on this new LV
mkfs.ext3 /dev/VG_XenStorage-43851e54-d3bf-0602-5e84-93629cfe7851/iso-images
8. create a mount point
mkdir /mnt/iso-images
9. make the LV in the VG known to the kernel
vgchange -a y
10. create the repository
xe sr-create name-label=iso-images type=iso device-config:location=/mnt/iso-images/ device-config:legacy_mode=true content-type=iso
11. confirm new repository listed in XenServer
xe sr-list
12. mount the new FS
mount /dev/VG_XenStorage-43851e54-d3bf-0602-5e84-93629cfe7851/iso-images /mnt/iso-images/
13. [OPTIONAL] edit /etc/fstab to mount at boot
After following these steps, you can now use something like wget to download ISO images to the /mnt/iso-images mount and have them available to XenServer.
