44 Configuring Storage
6 Find the physical volume device SCSI device mapping name on which the
SR exists.
Identify the volume group (VG) corresponding to the SR.
Run the following command on the XenServer host:
# pvs
The output of this command is similar to the output given below:
P V V G
Fmt Attr PSize PFree
/dev/sdd VG_XenStorage-058e9a1d-9b7e-71bc-
7a4c-5b78d6e30bcb lvm2 a- 80.00G 38.00G
/dev/sde VG_XenStorage-4684b6c6-be6d-6267-
b7b5-834a1fd30f65 lvm2 a- 59.99G 45.99G
The volume groups (VG) are named as VS_XenStorage-<SR UUID>.
7 Use the SR UUID noted in step 2 to identify the correct volume group and
the corresponding Physical Volume (PV) from the output of the above
command.
8 To resize the physical volume, run the following command:
# pvresize /dev/sd<x>
9
To scan the SR, run the following command:
# xe sr-scan uuid=<SR UUID>
10
The SR size now gets updated to the new size of the physical volume.
11 Turn on the VMs.
