First we need to check free local disk space on XenServer:

 

# df -h

Filesystem            Size  Used Avail Use% Mounted on

/dev/sda1             4.0G  1.9G  1.9G  51% /

none                  373M  4.0K  373M   1% /dev/shm

/opt/xensource/packages/iso/XenCenter.iso

                       52M   52M     0 100% /var/xen/xc-install

#

 

You can clearly see there is not much disk space left on /dev/sda1.

 

Now you need to create a new Logical Volume (LV) that will have enough space for our ISO images.

 

First check the available physical disk space:

 

# pvs

  PV         VG                                                 Fmt  Attr PSize   PFree 

  /dev/sda3  VG_XenStorage-8eaf2053-79bc-3284-1b70-13a714db05eb lvm2 a-   457.75G 199.96G

#

 

Then check the Volume Group(s) (VG):

 

# vgs

  VG                                                 #PV #LV #SN Attr   VSize   VFree 

  VG_XenStorage-8eaf2053-79bc-3284-1b70-13a714db05eb   1   7   0 wz--n- 457.75G 199.96G

#

 

Then create the new LV in the available VG (I have only one):

 

# lvcreate -L 10G -n isoImages VG_XenStorage-8eaf2053-79bc-3284-1b70-13a714db05eb

 

Now you have to make a filesystem on this new LV. I've made mine ext3.

 

# mkfs.ext3 /dev/VG_XenStorage-8eaf2053-79bc-3284-1b70-13a714db05eb/isoImages

mke2fs 1.39 (29-May-2006)

Filesystem label=

OS type: Linux

Block size=4096 (log=2)

Fragment size=4096 (log=2)

1310720 inodes, 2621440 blocks

131072 blocks (5.00%) reserved for the super user

First data block=0

Maximum filesystem blocks=2684354560

80 block groups

32768 blocks per group, 32768 fragments per group

16384 inodes per group

Superblock backups stored on blocks:

        32768, 98304, 163840, 229376, 294912, 819200, 884736, 1605632

 

Writing inode tables: done                           

Creating journal (32768 blocks): done

Writing superblocks and filesystem accounting information: done

 

This filesystem will be automatically checked every 24 mounts or

180 days, whichever comes first.  Use tune2fs -c or -i to override.

#

 

Now you need to create a mount point:

 

# mkdir /mnt/isoImages

 

You need to make the LV in the VG known to the kernel:

 

# vgchange -a y

 

Create the repository:

 

# xe sr-create name-label=ISOimages type=iso device-config:location=/mnt/isoImages/ device-config:legacy_mode=true content-type=iso

 

You should see your new repository listed in XenServer:

 

# xe sr-list

 

uuid ( RO)                : 3f492136-d7ba-360e-8a83-c324be44a676

          name-label ( RW): ISOimages

    name-description ( RW):

                host ( RO): XenBelut

                type ( RO): iso

        content-type ( RO): iso

 

#

 

Now you can mount the new FS:

 

# mount /dev/VG_XenStorage-8eaf2053-79bc-3284-1b70-13a714db05eb/isoImages /mnt/isoImages/
