Hi
Aren't there any kernel write errors in your 'dmegs'.
LV becomes fragile if the associated devices with cache are having HW
issues (disk read/write errors)
Zdenek
Is that true even when using a writethrough cache mode?
With writethrough - all writes are first committed on 'origin' disk - before
they are ack back to writing apps - so cache can be through away anytime.
When cache will experience write error - it will become invalidate and will
need to be dropped - but this thing is not automated ATM - so admin
works is needed to handle this task.
