I noticed (actually looked at my serial console logs :) that GEOM appears
to be tasting the zvols being exported via iscsi(istgt). For instance:
GEOM_MULTIPATH: da405 added to Z22
GEOM_MULTIPATH: da406 added to Z23
GEOM_MULTIPATH: da407 added to Z24
ZFS filesystem version 5
ZFS storage pool version 28
GEOM_PART: integrity check failed (zvol/pool0/d00000003_300g_16k, MBR)
GEOM_PART: integrity check failed (zvol/pool0/d00000003_300g_16k at snap1, MBR)
GEOM_PART: integrity check failed (zvol/pool0/d00000001_300g_16k, MBR)
GEOM_PART: integrity check failed (zvol/pool0/d00000001_300g_16k at snap1, MBR)
The zvols have never been accessed/formatted from the local system
except via the istgt daemon from the client.
Is there a way to disable this that I've somehow missed? man 4 GEOM
mentions "tasting" and the logic around this operation. A google search
shows a couple of similar questions - no discrete answers.
