Failed mirror in VM Host storage allocated to VM Guests

[Torsten.]

This looks like your only choice so far, because the device remains "busy" until a reboot, but after a reboot you cannot do the "replace" command...

This disk is one of 8 (ie 4 mirrored) each disk is mirrored strictly to its corresponding partner. e.g.

c2t3d0 is mirrored to c1t3d0
c2t4d0 is mirrored to c1t4d0

etc, etc. If I use the new disk instead of rebooting, it would change that, however its a consideration to avoid a reboot.

The disk is one of 4 and all 4 disks are in each LV.

e.g.
LV01 has all 4 disks contained within
LV02 has all 4 disks contained within
LV03 has all 4 disks contained within

There are two PVGs vmos_primary and vmos_mirror

The failed disk is from vmos_primary PVG in Volume group vg_vmos.

I'm unsure how to get the new disk into vmos_primary PVG and then exactly mirrored to its device counterpart (currently being used by the VG) in vmos_mirror PVG.

Once I have done this, I presume I can just use lvextend and increase mirror copies to 1 again for each LV presumably specifying all 4 of the mirror disks in the command
