InfoScale features restrictions
The following InfoScale software features are restricted in the split InfoScale stack model:
Smartmove and Thin Reclamation - These features require co-ordination between VxVM and VxFS and hence are not supported in this model.
VxVM volume snapshots - Due to the inability of VxFS in the guest domain to coordinate with VxVM in the control domain, taking a data consistent snapshot of a VxVM volume containing a VxFS file system requires shutting down the application and unmounting the file system before taking the snapshot.
Resizing VxVM volumes and any type of file system on top of the volume with vxresize - Resizing any type of file system on the guest whose underlying device is backed by a VxVM volume in the control domain, requires resizing the VxVM volume and the file system in the guest individually.
If you are growing a VxFS file system in the guest whose underlying device is backed by a VxVM volume requires you to first grow the volume in the control domain using the vxassist command, and then the file system in the guest domain using the fsadm command.
Shrinking a VxFS file system, on the other hand, requires you to first shrink the file system in the guest domain using the fsadm command, and then the volume in the control domain using the vxassist command. Using the vxassist command requires you to use the -f option of the command, as in the following example.
# vxassist -g [diskgroup] -f shrinkto volume length
Caution:
Do not shrink the underlying volume beyond the size of the VxFS file system in the guest as this can lead to data loss.
Exporting a volume set to a guest domain is not supported.
Veritas Volume Replicator is not supported in the Split InfoScale stack model.
Multi-volume DST
File-level Smartsync
The following VxFS tunables are not set to their default values based on the underlying volume layout, due to VxFS being in the guest domain and VxVM being installed in the control domain:
read_pref_io
write_pref_io
read_nstream
write_nstream
If desired, you can set the values of these tunables based on the underlying volume layout in the
/etc/vx/tunefstabfile.See the Storage Foundation Administrator's Guide for more information about tuning I/O.
InfoScale Enterprise is not supported in this deployment model.
