Error Message

# vxassist -g thindg -b mirror thinvol layout=nostripe alloc=thindg206,thindg207,thindg208,thindg209,thindg210,thindg211,thindg212,thindg213,thindg215 mirror=enclr
VxVM vxplex ERROR V-5-1-14671 Volume thinvol is configured on THIN luns and not mounted. Use 'force' option, to bypass smartmove. To take advantage of smartmove for supporting thin luns, retry this operation after mounting the volume.
VxVM vxplex ERROR V-5-1-407 Attempting to cleanup after failure ...

Cause

Unable to mirror volume where the underlying luns are of type "thin_reclaim"

Resolution

To resolve the issue and enable the mirroring of the volume which is configured on thin reclamation LUN's, we need to use 'force' option to bypass smartmove OR to try and disable smartmove completely.

To use the 'force' option:

# vxassist -g thindg -b -o force mirror thinvol layout=nostripe alloc=thindg206,thindg207,thindg208,thindg209,thindg210,thindg211,thindg212,thindg213,thindg215 mirror=enclr
 

OR

 

To disable smartmove:


# vxdefault set usefssmartmove none

To verify the new setting:

# vxdefault list

# vxassist -g thindg -b mirror thinvol layout=nostripe alloc=thindg206,thindg207,thindg208,thindg209,thindg210,thindg211,thindg212,thindg213,thindg215 mirror=enclr
