Configuring Storage 43
Resizing An SR After Changing the Size of An
LVM-Based Storage Volume
If you change the size of a LVM-based volume (SAS, iSCSI, or Fibre
Channel)—for example, if you increase the size of the volume on your iSCSI
storage array—the size of the SR on that volume does not get updated.
To adjust the size of the SR:
1
Turn off all virtual machines on the SR.
2 Note the universally unique identifier (UUID) of the SR.
Run the
xe sr-list command on the XenServer host and identify the
SR by its name label.
3 To identify the Physical Block Device (PBD) UUID corresponding to the
SR, run the following command on XenServer:
# xe sr-param-list uuid=<SR UUID>|grep PBD
where <SR UUID> is the UUID of SR noted in step 2
4 To unplug the Physical Block Device (PBD) corresponding to the Storage
Repository, run the following command:
# xe pbd-unplug uuid=<PBD UUID>
where <PBD UUID> is the UUID of PBD noted in step 3.
5 To plug the PBD, run the following command:
# xe pbd-plug uuid=<PBD UUID>
